For those of you who haven't read the books in a while or are just looking for something to clarify, I have pulled some things for you to look at. I pulled it off of wikepedia, so some of the things might not be correct, but the are for what we need them for.
Using magic
For a person's ability to perform magic to be of use, much training is needed. When "wild," typically with young and untrained children, magic will still manifest itself subconsciously in moments of strong apprehension, fear or anger. For example, Harry Potter once made his hair grow back after a bad haircut, and, in anger, made his Aunt Marge inflate enormously. Whilst this reaction is usually uncontrollable, Tom Marvolo Riddle, later known as Lord Voldemort, was able to "make things move without touching them...make animals do what he wanted without training them...make bad things happen to people who annoy him...or 'make them hurt if I [he] want to'" when he was a young child, apparently intentionally. In addition, Lily Potter was able to guide and control the blades of a flower by wanting to. Almost all magic is done with the use of a supporting tool or focus, typically a wand. On the subject of magic without the use of a wand, Rowling says:
A wizard or witch is only at their best when using their own wand. Throughout the series, it is evident that when using another's wand, one's spells are not as strong as they normally would be.[ Ownership of a wand can transfer from one person to another if the original owner of the wand is forcibly disarmed (either magically or manually, as evident from Draco Malfoy's magical disarming of Dumbledore in Half-Blood Prince and Harry's manual disarming of Draco in Deathly Hallows). Moreover, if a person has the allegiance of more than one wand, and one of them is forcibly taken away, the other wands that respond to this person will also change their allegiance (Harry's taking Draco's hawthorn wand in Malfoy Manor in Deathly Hallows, leads to the Elder Wand also accepting Harry as its master: "Does the wand in your hand know that its last master was disarmed? Because if it does... I am the true master of the Elder Wand.")
Within the books, technical details of magic are obscure. Of Harry's lessons, only those involving magical creatures, potions or divination are given in any detail.
Severus Snape once told Harry Potter that "Time and space matter in magic..." during Harry's first Occlumency class in Harry Potter and the Order of the Phoenix and Albus Dumbledore told Harry after finding the magically concealed boat to reach the locket Horcrux that "Magic always leaves traces, sometimes very distinctive traces."
The limits of magic
Before publishing the first Harry Potter novel, Rowling spent five years establishing the limitations of magic; determining what it could and could not do. "The most important thing to decide when you're creating a fantasy world," she said in 2000, "is what the characters CAN'T do." For instance, while it is possible to conjure things out of thin air, it is far more tricky to create something that fits an exact specification rather than a general one; moreover, any objects so conjured tend not to last.
Harry's status as an orphan from the first book quickly establishes that resurrection of the dead is impossible. While corpses can be transformed into obedient Inferi on a living wizard's command, they are little more than zombies with no soul or will of their own. It is also possible through the rare Priori Incantatem effect to converse with ghost-like "shadows" of magically murdered people. The Resurrection Stone also allows one to talk to the dead, but those brought back by the Stone are not corporeal, nor do they wish to be disturbed from their peaceful rest. Throughout the series, this limit is continually mentioned, and wizards try to transcend it at their own folly.
Likewise, it is not possible to make oneself immortal unless one makes use of a mystical object of great power to sustain life (such as the Philosopher's Stone created by Nicolas Flamel or a Horcrux, the latter having been used by Tom Riddle). If one were to possess the three Deathly Hallows, it is fabled that they would possess the tools to become the "master of death". However, it is hinted that being a true "master of death" is to be willing to accept that death is inevitable. Becoming a ghost is also an option for wizards and witches; however, it is said that it is "a pale imitation of life." Whether or not ghosts are sentient is not told. However, Snape states that a ghost is merely "the imprint of a departed soul left upon the earth"
True love is almost impossible to create magically, though Amortentia, a love potion, can create a powerful sense of infatuation.
Magic and emotion
A witch or wizard's emotional state can affect their inherent abilities. In Half-Blood Prince, Nymphadora Tonks temporarily lost her power as a Metamorphmagus after suffering sadness over her grief for the death of Sirius Black, and for her love for Remus Lupin, who wanted to distance himself from her due to his being a werewolf. The form of her Patronus changed to reflect her depression. As related to Harry by Dumbledore, Merope Gaunt only demonstrated any magical ability when removed from her father's oppression, but then seemed to lose it again when her husband abandoned her. Many other examples of emotion-influenced magic appear throughout the series, with Ariana Dumbledore, and Harry's attack upon Aunt Marge in Harry Potter and the Prisoner of Azkaban, being prime examples. Several magical spells involve the use of emotion when casting them. The Patronus charm, for example, requires the caster to concentrate on a happy memory. Force of will under extenuating circumstances also helps in casting spells, and affects the force with which they are cast. An example of this is when Harry is able to conjure a corporeal Patronus when Sirius Black is in danger of being administered the Dementor's Kiss.
Magic and death
Death is studied in detail in a room (called the Death Chamber) of the Department of Mysteries containing an enigmatic veil. Sirius Black falls through this veil after he is hit with a curse from Bellatrix Lestrange. Magical techniques have been used to extend life. The Philosopher's Stone can be used to prepare a potion that postpones death for the rest of eternity, so long as the potion is drunk on a regular basis. Voldemort has availed himself of other methods, being one of the few wizards ever to use Horcruxes in his long sought attempt to "conquer death", and is believed to be the only one to use multiple Horcruxes. In addition, the drinking of Unicorn blood will keep a person alive even if death is imminent, but at the terrible price of being cursed forever. Being magical can contribute to one's longevity, as there are several characters in the series who are quite long-lived (such as Griselda Marchbanks, who was an invigilator during Albus Dumbledore's O.W.L examinations).
It is revealed by Nearly Headless Nick in the fifth book that all witches and wizards have the choice of becoming ghosts when they pass away. The alternative is "passing on". Nick says that he became a ghost because he was foolish, "afraid of death." All Hogwarts headmasters appear in a portrait when they die, allowing consultation by future generations.
In Harry Potter and the Goblet of Fire, Dumbledore says that there is no spell that can truly bring the dead back to life, however several cases of dead people becoming half-alive are known. In the Goblet of Fire, because of a connection between Harry and Voldemort's wands, images of Voldemort's recent victims appear and help Harry escape. According to Harry, they seemed too solid to be ghosts.
In Deathly Hallows, a magical item known as the Resurrection Stone is said to have the power to raise the dead. According to the legend of the Deathly Hallows, however, the people do not feel as if they belong in the human world and prefer to stay in their resting place. They are mere spirits, imitations and shadows of who they used to be.
Magic and love
In Harry Potter, love is treated as a branch of magic, although it does not seem to be something that is easily controlled, rising unbidden from the emotion itself. Lily’s sacrifice on Harry’s behalf, for example, comes around at the end of the series to work to Harry’s advantage in unforeseen ways. Love is a big theme in the books, and it is implied that it is Voldemort’s inability to understand the concept that leads to his eventual downfall. Since he does not understand the selfless love contained in Lily’s sacrifice, he is unable to predict the consequences of Harry’s own sacrifice at the end of Deathly Hallows. Thus he is unprepared for the fact that Harry’s friends are protected from his spells. Voldemort also unwittingly ensures that Harry is tied to life while Voldemort lives, by taking some of his blood in the hope that he will be able to gain some of the protection that lingers in Harry as a result of Lily’s sacrifice.
It is implied that the inability to love is what make Voldemort as evil as he is. Severus Snape, who voluntarily joined the Death Eaters on leaving Hogwarts, turns spy for the Order of the Phoenix when he realises that the woman he loves is being threatened by Voldemort. Similarly, Narcissa Malfoy’s love for her son Draco eventually leads her to betray Voldemort, directly leading to Harry’s survival – another oversight on Voldemort’s part. With these examples, the book strongly hints that anybody with the ability to love cannot go as far down the path of evil as Voldemort has done, and it is his complete lack of compassion that makes him capable of what he does.
Selflessness is a concept strongly tied to love in the books. Sacrifice of one’s life for the people one loves is seen in Harry’s case as well as Lily’s. Also, when confronting Wormtail about his betrayal of the Potters, Sirius tells him “You should have died for them! As we would have done for you!
Spellcasting
Spells are the every-purpose tools of a wizard or witch; short bursts of magic used to accomplish single specialised tasks such as opening locks or creating fire. Typically casting requires an incantation, most often in a modified form of Latin (see Dog Latin), and gesturing with a wand. However, these seem to be aids to the will only; wands are in most cases required, but there are indications that sufficiently advanced witches and wizards can perform spells without them. Spells can also be cast non-verbally, but with a wand. This technique is taught in the sixth year of study at Hogwarts and requires the caster to concentrate on the incantation. Some spells (e.g. Levicorpus) are apparently designed to be used non-verbally. While most magic shown in the books requires the caster to use their voice, some do not (and this may depend on the witch or wizard). Dumbledore has been known to do impressive feats of magic without speaking, such as conjuring enough squashy purple sleeping bags to accommodate the entire student population or during his duel with Voldemort towards the end of Order of the Phoenix.
It is evidently also possible to use a wand without holding it. Harry himself performs Lumos to light his wand when it is lying on the ground somewhere near him. Additionally, Animagi and Metamorphmagi do not need wands to undergo their transformations.
Spells are divided into rough categories, such as "charms", "curses", "hexes", or "jinxes". Although offensive and potentially dangerous curses exist in number, three are considered usable only for great evil, which earns them the special classification of "Unforgivable Curses".
Magical abilities
The following is a list of special abilities that a wizard or witch in the Harry Potter universe may have.
Animagi transformation
An Animagus is a witch or wizard who can turn into a particular animal or magical creature at will. This ability is not innate: it must be acquired by magical means. All Animagi must register at a central authority; it is illegal to obtain this ability without registering, although out of the five Animagi described as such in the books (Minerva McGonagall, Rita Skeeter, James Potter, Sirius Black, and Peter Pettigrew), four either never registered before their death or are currently living and unregistered (McGonagall is the only mentioned registered Animagus).
Animagi transformation is one of the few forms of magic that can be performed deliberately wandlessly. One example of this is that, while both Sirius and Peter are left wandless for over 10 years, both retain the ability with supposedly no ill effects. When Animagi transform, the animal appears to be a normal animal. However, during Prisoner of Azkaban, it is noted that Ron's pet rat, Scabbers (later revealed as Peter Pettigrew's animagus form) has lived over twelve years when only expected to live three. Also, an animagus in animal form retains the ability to think like a human, which is the principal difference from being an animagus and being transfigurated into an animal. Also, while in their human forms, both Sirius Black and Peter Pettigrew were noted to look something like their animal forms.
Each Animagus has a specific animal form, and cannot transform into any other animal. The animal cannot be chosen: it is uniquely suited to that individual's personality, like the Patronus Charm, and in most cases the Animagus will change into the same animal used in the person's Patronus charm. (McGonagall's Patronus is a cat, like her Animagus form; James Potter's was a stag, which was also his Animagus form.) Similarly, when an Animagus transforms it is always into the same animal (i.e. same markings, same colours, etc.). When an Animagus registers, they must record all the defining physical traits of their animal form so that the Ministry can identify them.
Explicit emphasis is made in the books on the differences between Animagi and werewolves. Animagi have full control over their transformations and retain their minds, whereas werewolves' transformations are involuntary and include severe changes in personality. After the person has transformed into a werewolf, he no longer remembers who he is; he would kill his best friend if he got anywhere near him. A werewolf only responds to the call of his own kind. The only way that a werewolf can retain his sanity, intelligence and memory while transformed is using the Wolfsbane Potion.
Rowling also makes it clear in The Tales of Beedle the Bard that an animagus is not the same as a wizard simply transfiguring themselves into an animal. The former ability, as mentioned above, allows the witch or wizard to maintain their own mind and human powers of reasoning and memory. The latter however would cause the person to gain the brain of the animal they have transfigured into. This would lead to the obvious problem that they would forget that they were a wizard and be trapped, unknowing, in this form for the rest of that creature's lifespan unless transformed back by another wizard.
Metamorphmagi
A Metamorphmagus (a portmanteau of metamorph and magus) is a witch or wizard born with the innate ability to change some or all of their appearance at will. The talent cannot be acquired; a witch or wizard who has it must be born with it.
Nymphadora Tonks and her son, Teddy Lupin are currently the only known Metamorphmagi in the series; it is a very rare ability, possibly hereditary. Tonks is known to change her hair color and style according to her mood. Indeed, she even appears as an old woman on occasion. Her son, Teddy Lupin, also inherited this trait, as his hair is mentioned repeatedly changing colour.
The extent of these appearance-altering abilities and the limits thereof are not entirely clear. According to Rowling, a Metamorphmagus can alter his or her appearance completely, for instance, from black to white, young to old, handsome to plain and so on. In one example, Tonks changes her facial appearance by reshaping her nose into "a beaklike protuberance like Snape's", to "something resembling a button mushroom", and "one like a pig snout" which reminded Harry of his cousin Dudley's.
Parselmouth
Parseltongue is the language of snakes. It is, in the common mind, associated with Dark Magic (although Dumbledore has stated that it is not necessarily an evil quality), and those possessing the ability to speak it ("Parselmouths") are very rare. It appears to be a skill acquired through both learning or via a method of xenoglossia, such as through genetic inheritance (or by use of Dark or dangerous Magic). Harry was a Parselmouth: it was revealed in Harry Potter and the Chamber of Secrets to be due to Voldemort's passing on some of his abilities to Harry the night he tried to kill him. In Deathly Hallows it is revealed that it is a part of Voldemort's soul within Harry that grants him this ability, which is later destroyed leaving Harry stripped of the ability.
Other known Parselmouths include: Herpo the Foul; Salazar Slytherin and his descendants, including the Gaunts and Voldemort. Dumbledore can also understand Parseltongue; however, he learned it and did not naturally possess the ability. In Half-Blood Prince he repeats Morfin Gaunt's words "the big house over the way", which were spoken in Parseltongue.
Ginny Weasley is not a Parselmouth, although at points in Chamber of Secrets she appeared to speak in Parseltongue: she was at the time being possessed by the spirit of Tom Marvolo Riddle, who was himself Voldemort, a Parselmouth. Ron uses Parseltongue in the final book to reopen the Chamber of Secrets, but only through persistently trying to mimic the sounds that Harry made.
Rowling borrowed the term from "an old word for someone who has a problem with the mouth, like a hare lip."
Flying
Flight without aid of a broomstick or other object is a relatively rare ability. Voldemort can do this without the aid of a broom or carpet, as can Snape.
Objects are also known to be enchanted so they fly. Sirius had a flying motorbike that he lent to Hagrid to bring Harry to the Dursleys, and Arthur Weasley enchanted a Ford Anglia to fly. However, because of a loophole in the law (it is illegal to enchant certain Muggle Artifacts) that Mr. Weasley himself made, he was not technically in the wrong.[ The enchantments cast on these machines do not affect their normal functions and purposes, except the ability of flight.
Seers
A Seer is a witch or wizard with the clairvoyant ability to predict future events. The predictions given through this ability can sometimes be self-fulfilling prophecies, and Dumbledore states in Order of the Phoenix that not all of them come true, depending on the choices made by those mentioned. This would seem to indicate that a Seer predicts possible or likely events, at least in some cases. Sybil Trelawney is noted to never remember that she has made a prophecy when it is a true one. She speaks in a hoarse voice and only if a wizard is present will anyone know about it.
Each prophecy made by a Seer is recorded in a glass sphere and stored in the Hall of Prophecy of the Department of Mysteries within the Ministry of Magic. Only a person mentioned in a prophecy can safely retrieve it; anyone else who tries to do so will be driven insane.
According to McGonagall, true Seers are extremely rare. Sybill Trelawney is the only Seer shown in the books, although it is mentioned that Sybill's great-great-grandmother, Cassandra Trelawney, was a renowned Seer in her day. Trelawney is considered an "old fraud" by her students, and is sacked by Dolores Umbridge in the fifth book for it. However, she has twice made true prophecies (not counting 'minor' predictions such as Neville's breaking a teacup, the death of Lavender Brown's rabbit Binky and Hermione's quitting Divination. It is unclear whether Trelawney's visions of the Grim 'following' Harry in his third year are Sirius Black in Animagus form or just Trelawney being melodramatic and predicting the death of a student as she has done every year).
Legilimency and Occlumency
Legilimency is the magical skill of extracting feelings and memories from another person's mind — a form of magical "telepathy" (although Snape, an able practitioner of the art, dismisses the colloquial term, "mind-reading", as a drastic oversimplification). It also allows one to convey visions or memories to another person, whether real or imaginary. A witch or wizard possessing this skill is called a Legilimens, and can, for example, detect lies and deceit in another person, witness memories in another person's past, or "plant" false visions in another's mind.
The counter-skill to Legilimency is Occlumency (and its user, known as an Occlumens), by which one can compartmentalise one's emotions, or prevent a Legilimens from discovering thoughts or memories which contradict one's spoken words or actions. An advanced form of Occlumency is planting false temporary memories inside an Occlumens´ own head while blocking all other true memories, so if a Legilimens, even a highly skilled one, were to attempt to read the mind he or she would find false memories only and believe everything was right. This is how Snape was able to lie to Voldemort for years.
Voldemort, Snape, and Dumbledore are all known to be skilled in Legilimency and Occlumency. Throughout the books, Snape is repeatedly said to be highly skilled in Occlumency. Voldemort is said to be the master of Legilimency by Snape, as he, in almost all cases, immediately knows during conversations if someone lies to him.
The skills are first mentioned in Order of the Phoenix, (though Harry gets the impression before that Snape can read minds) wherein Snape is instructed by Dumbledore to give Harry lessons in Occlumency. Whether as a result of negligence in Snape's instruction, or poor aptitude on Harry's part, Harry never made any progress in the skill, and as a result he was lured by Voldemort through a carefully calculated vision he falsely believed to be real. Only once has Harry managed to overcome Snape with the use of Occlumency, in Order of the Phoenix. It seems that not everyone is able to master Occlumency. Also, although it appears to be an advanced form of magic, a young wizard can learn to be an Occlumens (Draco Malfoy was able to block Snape's attempt to use Legilimency on him in his 6th year, after being taught Occlumency by Bellatrix Lestrange). Near the end of Order of the Phoenix, Harry learns from Dumbledore that his love for Sirius is what caused Voldemort to release his possession of Harry. Revolting from the love in Harry, Voldemort feared the further use of Legilimency on Harry, drawing away from their connection. This allows Harry to freely see/feel Voldemort's thoughts/emotions in the next two books. In Deathly Hallows, Harry finally does master Occlumency - shutting his mind to Voldemort - when Dobby dies. He realises that his grief - or what Dumbledore calls it, love - is what can block out the Dark Lord.
Bellatrix Lestrange, Draco Malfoy, Narcissa Malfoy and Barty Crouch Jr also have skill in Occlumency, since Bellatrix was clearly said to have taught Draco to shield his thoughts from Snape. It was never clearly said that Narcissa was an Occlumens, but since she successfully managed to prevent Voldemort (the master of Legilimency) from detecting her lie about Harry's death, she is very likely to be one.
Legilimency and Occlumency are not part of the normal curriculum at Hogwarts, and most students would graduate without learning them. They seem to be considered a more advanced form of magic.
Apparition and Disapparition
Apparition is a magical form of teleportation, through which a witch or wizard can disappear ("Disapparate") from one location and reappear ("Apparate") in another. It is sometimes accompanied by a distinctive cracking or popping sound, though this is associated with ineptitude rather than success; the most skilled wizards can Apparate "so suddenly and silently" that they seem to have "popped out of the ground" (Dumbledore). The act is also accompanied by a very unpleasant squeezing sensation, as though being sent through a tight rubber tube, according to Harry.
The Ministry licenses apparition, and a witch or wizard must be 17 years old or older and have a licence to use Apparition in the same way real-world governments require individuals to have a licence to drive a motor vehicle. Students at Hogwarts may attend Ministry lessons in Apparition during their sixth year, and may take their examination once they turn seventeen.
The training is difficult, and students run the risk of splinching — being physically split between the origin and destination — which requires the assistance of the Ministry's Accidental Magic Reversal Squad to undo. Splinching is quite common during lessons, and can be uncomfortable (and at times rather gruesome) depending on the body parts splinched, but is ultimately harmless if properly reversed. Ron left behind half of an eyebrow during his first Apparition exam, causing him to fail, and splinched himself twice in The Deathly Hallows.
For reasons of security, the grounds of Hogwarts are protected by ancient Anti-Apparition and Anti-Disapparition spells, which prevent humans from using Apparition in the school grounds. This does not extend to magical creatures such as house-elves and phoenixes, who can still use their own form of Apparition. It is also possible to prevent individuals from using Apparition, as Dumbledore did with the Death Eaters in Order of the Phoenix, whom he held until Ministry officials could take them into custody.
It is considered rude to Apparate directly into a private area, such as a home. Dumbledore stated in the 6th book that it would be "quite as rude as kicking down the front door". For this reason, and for reasons of security, many homes also have Anti-Apparition spells protecting them from uninvited intrusions. The accepted way to travel to a home is to Apparate near the destination, and continue to the final destination on foot. Apparition is considered unreliable over long distances, and even experienced users of the technique sometimes prefer other means of transport, such as broomsticks.
A wizard or witch can use Side-Along Apparition to take others with them during Apparition. Dumbledore uses this on Harry several times, and notably, Harry uses Side-Along Apparition to take the weakened Dumbledore back from the seaside cave containing Voldemort's locket Horcrux. This was also Harry's first real Apparition outside of lessons and although unlicensed and never before having even tried Side-Along, he does it extremely successfully and later he, Hermione and Ron sometimes Side-Apparate each other as well. In addition, Dumbledore's phoenix, Fawkes, used Side-Along-Apparition to take Dumbledore with him when avoiding arrest from the Ministry. This suggests that phoenixes, like elves, can teleport anywhere, even in places with Anti-Apparition spells (this is also written in "Fantastic Beasts and Where to Find Them"). However, this ability may require more skill than normal Apparition or more concentration at least, as Hermione splinched Ron when she Side-Along Apparated him and Harry in a desperate moment. Dumbledore, who was much older and much more experienced, could Side-Along Apparate people with no problems as shown when he took Harry in this method multiple times.
In the Order of the Phoenix film, Death Eaters and Order members Apparated and Disapparated in clouds of smoke. Death Eaters would appear and disappear in black smoke, Order members in white. In the movie, both sides also seemed to be able to "half-apparate" in which their bodies were made out of smoke, giving them the ability to fly. This is not canon to the books and probably just used for more cinematic, atmospheric purposes. Interestingly, both times Fred and George apparated and disapparated, they did it with a pop as in the books.
It is shown that it is possible to Apparate without a licence; it's just not usually done unless in lessons and is illegal. In this way it seems to be similar to having a licence to drive a car as well: one doesn't need a licence to have the skill, but does need it to use the skill legally. In Deathly Hallows, Harry did not possess a licence, while Hermione and probably Ron did, but he appeared more skilled at Apparating than Ron as he has never splinched himself or others and Ron has splinched himself at least a few times. In the books, it was indicated that while Ron could Apparate, he wasn't very good or skilled at it. He splinched himself at least twice (although both times it was extremely minor) and Harry and Hermione were able to Apparate before he could. When extra lessons were mentioned, Harry had been able to Apparate once in the previous lesson and Hermione had managed it twice and passed her test easily the first time. In contrast Hermione seemed to have no problems Apparating, except the one time when she tried Side-Along and splinched Ron, but she was in a very difficult circumstance then, and managed it perfectly on all the numerous other occasions that she used Side-Along. In Harry's first official Apparition (and the first one of the trio to do it in more than lessons or the test) he not only did not splinch himself, he managed to Side-Apparate Dumbledore and get them both over an unspecified distance on the first try with no problems.
In the books, the words "Apparate" and "Disapparate", like many other neologisms used by Rowling, are capitalised, whereas established English words such as "jinx" and "hex" are not. The words themselves are most likely derived from the French apparaître and disparaître meaning to appear and disappear, although before Charles Fort's invention of the term "teleportation" in the 1930s, it was known as "apportation". Another possible derivation is from the English word “Apparition” meaning to appear suddenly or dramatically, which comes from the Latin "apparitio" meaning attendance. "Disapparate" probably comes from the same word but with the prefix: “dis-” expressing negation or reversal.
Other teleportation
Some other forms of instantaneous movement occur in the books, such as a house elf's ability to teleport or Fawkes's ability to disappear in a burst of flame. (In Fantastic Beasts and Where to Find Them, it is stated that all phoenixes have this ability.) In the novels, Harry refers to this as "Apparition" but this may be because of Harry's inexperience and not fact. This theory is further reinforced as neither Fawkes nor house-elves are restricted by anti-Apparition magic. Fawkes also vanishes silently and in a burst of flame, whereas a wizard Apparating is accompanied by a very loud "crack" (or a quiet "pop") with no visible effect.
Floo Powder is also used to teleport. The wizard/witch takes a small pinch of floo powder and throws it into a fire. The fire will turn an emerald green and the wizard/witch will shout where they wished to go. Harry used Floo powder before and shouted 'diagonally', instead of 'Diagon Alley' and ended up in Knockturn Alley.
Another method of teleportation is by portkey. With ministry permission, an object can be turned into a portkey. A portkey will teleport itself and anyone touching it at a specified time to a pre-chosen destination. Harry, the Weasleys, and Amos and Cedric Diggory take a portkey to the Quidditch World Cup in Goblet of Fire. The Triwizard cup was a portkey that took Harry and Cedric to the cemetery where Voldemort's father was buried. In book five, Dumbledore creates an illegal portkey to take Harry and the Weasley children to Number 12, Grimmauld Place after Mr. Weasley is injured.
In addition, Vanishing Cabinets allow one to teleport, although the only one in the series (first seen in Chamber of Secrets) is initially broken. Only after Draco Malfoy repairs it in the Half Blood Prince can Death Eaters teleport into Hogwarts, bypassing the protections.
Veela charm
An ability attributed to Veela and those of Veela heritage, such as Fleur Delacour. It is used to charm males, much like the Sirens in The Odyssey.
Harry seems more resistant to this than Ron and most others, though the first time he was exposed to it his reaction was similar to Ron's. Men who are exposed to it over time become more resistant to it, although the Veela charm takes full effect if the Veela surprises the man, as noted by Ron in 'The Half-Blood Prince'. It is possible that Victoire Weasley has inherited this ability from Fleur. As no men of Veela descent have been portrayed in the books (although Bill and Fleur have a son named Louis, as well as two daughters), it is unknown whether they would also have this ability.
As shown in Goblet of Fire, Veela hair can be used as cores to create wands. According to famed wandmaker Mr. Ollivander, these wands are a little "temperamental". Since Fleur's contains one of her grandmother's hairs, being a positive familial bond, no inherent problem is seen within this particular wand.
Magical resistance
This refers to a certain degree of immunity against hexes and spells found in powerful creatures such as trolls, dragons, and giants. Hagrid is resistant to certain spells, like the Stunning Spell, due to his giant blood. This type of resistance is not insurmountable; if enough Stunning Spells, for example, are fired at a creature with magical resistance at once, the creature may still be rendered unconscious. Also, wizards and witches can resist a spell with the power of their own sheer will, such as Harry did in book 4, when Barty Crouch Jr. disguised as Alastor Moody tried to control Harry with the Imperius curse and Harry resisted.
Spell-like effects
Unbreakable Vow
The Unbreakable Vow is a voluntary agreement made between two witches or wizards. It must be performed with a witness ("Bonder") on hand, holding their wand on the agreeing persons' linked hands to bind them with magic as a tongue of flame. The Vow is not literally "unbreakable" as the person taking it is still able to go back on his or her word, but doing so will cause instant death. The Unbreakable Vow was first introduced in Half-Blood Prince, in which Snape made a promise to Narcissa Malfoy to protect Draco, with Bellatrix as the "Bonder", as her son attempted to fulfill the Dark Lord's task, and for Snape to fulfill the task if something should prevent Draco from doing it. Another example in Half-Blood Prince occurs when Ron tells Harry how Fred and George tried to make him undertake an Unbreakable Vow, but because of their father's intervention, they did not succeed.
Priori Incantatem
Priori Incantatem, or the Reverse Spell Effect, is used to detect the spells cast by a wand. The spells cast by the wand will emerge in smoky or ghost-like replicas in reverse order, with the latest spell emerging first. It is first encountered in Goblet of Fire when the house elf Winky is found holding Harry's wand. This spell is used to reveal that it was indeed Harry's wand that cast the Dark Mark. In Harry Potter and the Half Blood Prince, it is revealed that the teenage Voldemort murdered his father and grandparents using his uncle Morfin's wand, knowing that, when examined, the wand would incriminate Morfin as the murderer. In Deathly Hallows, Harry feared that a Priori Incantatem spell would be used on Hermione's wand after the Death Eaters had a hold of it. This would reveal that she had accidentally broken his holly and-phoenix-feather wand (with her wand) when a curse misfired and they both narrowly escaped Voldemort earlier. As a result, the protection of the shared cores was lost and, worse still, this would now be made known to Voldemort. During the final duel between Harry and Voldemort, the latter mentions that he knows that the holly and phoenix wand is destroyed, implying that the Priori Incantatem had indeed been performed on Hermione's wand, as they had feared.
Forcing two wands that share the source of their cores to do battle can also cause a more potent form of Priori Incantatem. The tips of the two wands will connect, forming a thick golden "thread" of energy, and the two wands' masters fight a battle of wills. The loser's wand will regurgitate shadows of spells that it has cast in reverse order. This phenomenon occurred during the duel between Harry and Voldemort at the end of Goblet of Fire. Their simultaneous spells (Harry and Voldemort cast "Expelliarmus" and "Avada Kedavra" respectively) triggered the threads, and as Voldemort lost the battle of wills, his wand regurgitated, in reverse order, shades of the spells he had cast with it – screams of pain from torturing various victims, echoes of the people his wand had murdered: Cedric Diggory; Frank Bryce; Bertha Jorkins; as well as Harry's parents. Harry was previously informed by Mr. Ollivander that the holly wand that "chose" Harry was the "brother" of the yew wand that gave him the lightning-shaped scar on his forehead, although the significance of this was not discussed then. Dumbledore later revealed to Harry that his and Voldemort's wands both shared a tail feather given by Dumbledore's pet phoenix, Fawkes.
Dark Arts
The Dark Arts are those magical spells and practices that are usually used for malicious purposes. Practitioners of Dark Arts are referred to as Dark witches or wizards. The most prominent of these is Voldemort, known to them as the Dark Lord. His followers, known as Death Eaters, practice the Dark Arts while doing his bidding.
The type of spells characteristic of Dark Arts are known as curses, which usually cause harm to the target. All, to a certain degree, are in some circumstances justifiable. The motivation of the caster affects a curse's result. This is most notable in the case of Cruciatus: when cast by Harry, angered by the death of his godfather and desiring to punish the murderer, it causes a short moment of pain; as the murderer herself comments, righteous anger does not allow the spell to work for long. When cast by figures such as Voldemort, who desire to inflict pain for its own sake, it causes intense agony that can last as long as the Dark witch or wizard desires. Use of Dark Magic can corrupt the soul and body; Voldemort has used such magic in his quest to prolong his life and obtain great power. Dark Arts also caused Voldemort to look deformed and inhuman, a side effect of splitting his soul into Horcruxes.
According to Snape, the Dark Arts "are many, varied, ever-changing and eternal... unfixed, mutating, indestructible." They also appear to be the most common form of magic used by criminals, while dangerous spells used by others in the books are frequently labelled Dark. In magical dueling, for example, there are any number of spells that may be used to attack, immobilise, or disarm an opponent without causing pain or lasting harm; however, spells such as the Cruciatus Curse or Sectumsempra, judged to be Dark by reliable authorities, wound or seriously distress a victim in some way.
In the Wizarding world, use of the Dark Arts is strongly stigmatised and even illegal; however, these spells are prevalent enough that even before the rise of Voldemort, many schools, (including Hogwarts), taught Defence Against the Dark Arts as a standard subject. Techniques include anti-curses and simple spells to disable or disarm attackers or fight off certain creatures. Some schools, such as Durmstrang, teach Dark Magic. A Dark Arts class was also taught at Hogwarts while it was under Death Eater control.
Unforgivable Curses
The Unforgivable Curses are some of the most powerful known Dark Arts spells. They were first classified as unforgivable in 1717. Used by the books' villains, such as Voldemort and the Death Eaters and in some cases the Ministry of Magic, their use inspires horror and great fear amongst others. The curses are so named because their use is — except by Ministry authorisation — forbidden and unforgivable in the Wizarding world when used on another human or probably any sentient being. The use of any of these spells on another human being is punishable by a life sentence in Azkaban. These curses are thus very rarely used openly. However, in Deathly Hallows, the Unforgivable Curses are used liberally by good characters, ranging from Professor McGonagall with the Imperius Curse, to Harry effectively using the Cruciatus Curse. He also uses the Imperius curse on a goblin and a suspicious Death Eater during their disguised attack upon Gringotts Bank. However, at the time the Unforgivable curses had been made legal. Since the spells are very powerful, their use requires a strong desire to cause the effects, a directed will, and great skill.
It is noted that to perform the Unforgivable Curses, the caster must "mean it". This means that they need to want the effects a fair amount for the effects to last. In Order of the Phoenix, Harry attempts to use the Cruciatus Curse on Bellatrix, but he is drawing only from righteous anger and does not truly 'mean it'. Bellatrix explains that a caster must truly want their victim to suffer, and thus Harry's spell causes her to feel pain for only a moment. Nonetheless, the sheer force of the curse is enough to blast Bellatrix off of her feet.
The use of the Unforgivable Curses was authorised against Voldemort and his followers by Bartemius Crouch Sr, during the First Wizarding War. Shortly after his resurrection, Voldemort names two Death Eaters "killed by Aurors".
The Unforgivable Curses:
Using magic
For a person's ability to perform magic to be of use, much training is needed. When "wild," typically with young and untrained children, magic will still manifest itself subconsciously in moments of strong apprehension, fear or anger. For example, Harry Potter once made his hair grow back after a bad haircut, and, in anger, made his Aunt Marge inflate enormously. Whilst this reaction is usually uncontrollable, Tom Marvolo Riddle, later known as Lord Voldemort, was able to "make things move without touching them...make animals do what he wanted without training them...make bad things happen to people who annoy him...or 'make them hurt if I [he] want
”You can do unfocused and uncontrolled magic without a wand (for instance when Harry blows up Aunt Marge) but to do really good spells, yes, you need a wand.”
A wizard or witch is only at their best when using their own wand. Throughout the series, it is evident that when using another's wand, one's spells are not as strong as they normally would be.[ Ownership of a wand can transfer from one person to another if the original owner of the wand is forcibly disarmed (either magically or manually, as evident from Draco Malfoy's magical disarming of Dumbledore in Half-Blood Prince and Harry's manual disarming of Draco in Deathly Hallows). Moreover, if a person has the allegiance of more than one wand, and one of them is forcibly taken away, the other wands that respond to this person will also change their allegiance (Harry's taking Draco's hawthorn wand in Malfoy Manor in Deathly Hallows, leads to the Elder Wand also accepting Harry as its master: "Does the wand in your hand know that its last master was disarmed? Because if it does... I am the true master of the Elder Wand.")
Within the books, technical details of magic are obscure. Of Harry's lessons, only those involving magical creatures, potions or divination are given in any detail.
Severus Snape once told Harry Potter that "Time and space matter in magic..." during Harry's first Occlumency class in Harry Potter and the Order of the Phoenix and Albus Dumbledore told Harry after finding the magically concealed boat to reach the locket Horcrux that "Magic always leaves traces, sometimes very distinctive traces."
The limits of magic
Before publishing the first Harry Potter novel, Rowling spent five years establishing the limitations of magic; determining what it could and could not do. "The most important thing to decide when you're creating a fantasy world," she said in 2000, "is what the characters CAN'T do." For instance, while it is possible to conjure things out of thin air, it is far more tricky to create something that fits an exact specification rather than a general one; moreover, any objects so conjured tend not to last.
Harry's status as an orphan from the first book quickly establishes that resurrection of the dead is impossible. While corpses can be transformed into obedient Inferi on a living wizard's command, they are little more than zombies with no soul or will of their own. It is also possible through the rare Priori Incantatem effect to converse with ghost-like "shadows" of magically murdered people. The Resurrection Stone also allows one to talk to the dead, but those brought back by the Stone are not corporeal, nor do they wish to be disturbed from their peaceful rest. Throughout the series, this limit is continually mentioned, and wizards try to transcend it at their own folly.
Likewise, it is not possible to make oneself immortal unless one makes use of a mystical object of great power to sustain life (such as the Philosopher's Stone created by Nicolas Flamel or a Horcrux, the latter having been used by Tom Riddle). If one were to possess the three Deathly Hallows, it is fabled that they would possess the tools to become the "master of death". However, it is hinted that being a true "master of death" is to be willing to accept that death is inevitable. Becoming a ghost is also an option for wizards and witches; however, it is said that it is "a pale imitation of life." Whether or not ghosts are sentient is not told. However, Snape states that a ghost is merely "the imprint of a departed soul left upon the earth"
True love is almost impossible to create magically, though Amortentia, a love potion, can create a powerful sense of infatuation.
Magic and emotion
A witch or wizard's emotional state can affect their inherent abilities. In Half-Blood Prince, Nymphadora Tonks temporarily lost her power as a Metamorphmagus after suffering sadness over her grief for the death of Sirius Black, and for her love for Remus Lupin, who wanted to distance himself from her due to his being a werewolf. The form of her Patronus changed to reflect her depression. As related to Harry by Dumbledore, Merope Gaunt only demonstrated any magical ability when removed from her father's oppression, but then seemed to lose it again when her husband abandoned her. Many other examples of emotion-influenced magic appear throughout the series, with Ariana Dumbledore, and Harry's attack upon Aunt Marge in Harry Potter and the Prisoner of Azkaban, being prime examples. Several magical spells involve the use of emotion when casting them. The Patronus charm, for example, requires the caster to concentrate on a happy memory. Force of will under extenuating circumstances also helps in casting spells, and affects the force with which they are cast. An example of this is when Harry is able to conjure a corporeal Patronus when Sirius Black is in danger of being administered the Dementor's Kiss.
Magic and death
Death is studied in detail in a room (called the Death Chamber) of the Department of Mysteries containing an enigmatic veil. Sirius Black falls through this veil after he is hit with a curse from Bellatrix Lestrange. Magical techniques have been used to extend life. The Philosopher's Stone can be used to prepare a potion that postpones death for the rest of eternity, so long as the potion is drunk on a regular basis. Voldemort has availed himself of other methods, being one of the few wizards ever to use Horcruxes in his long sought attempt to "conquer death", and is believed to be the only one to use multiple Horcruxes. In addition, the drinking of Unicorn blood will keep a person alive even if death is imminent, but at the terrible price of being cursed forever. Being magical can contribute to one's longevity, as there are several characters in the series who are quite long-lived (such as Griselda Marchbanks, who was an invigilator during Albus Dumbledore's O.W.L examinations).
It is revealed by Nearly Headless Nick in the fifth book that all witches and wizards have the choice of becoming ghosts when they pass away. The alternative is "passing on". Nick says that he became a ghost because he was foolish, "afraid of death." All Hogwarts headmasters appear in a portrait when they die, allowing consultation by future generations.
In Harry Potter and the Goblet of Fire, Dumbledore says that there is no spell that can truly bring the dead back to life, however several cases of dead people becoming half-alive are known. In the Goblet of Fire, because of a connection between Harry and Voldemort's wands, images of Voldemort's recent victims appear and help Harry escape. According to Harry, they seemed too solid to be ghosts.
In Deathly Hallows, a magical item known as the Resurrection Stone is said to have the power to raise the dead. According to the legend of the Deathly Hallows, however, the people do not feel as if they belong in the human world and prefer to stay in their resting place. They are mere spirits, imitations and shadows of who they used to be.
Magic and love
In Harry Potter, love is treated as a branch of magic, although it does not seem to be something that is easily controlled, rising unbidden from the emotion itself. Lily’s sacrifice on Harry’s behalf, for example, comes around at the end of the series to work to Harry’s advantage in unforeseen ways. Love is a big theme in the books, and it is implied that it is Voldemort’s inability to understand the concept that leads to his eventual downfall. Since he does not understand the selfless love contained in Lily’s sacrifice, he is unable to predict the consequences of Harry’s own sacrifice at the end of Deathly Hallows. Thus he is unprepared for the fact that Harry’s friends are protected from his spells. Voldemort also unwittingly ensures that Harry is tied to life while Voldemort lives, by taking some of his blood in the hope that he will be able to gain some of the protection that lingers in Harry as a result of Lily’s sacrifice.
It is implied that the inability to love is what make Voldemort as evil as he is. Severus Snape, who voluntarily joined the Death Eaters on leaving Hogwarts, turns spy for the Order of the Phoenix when he realises that the woman he loves is being threatened by Voldemort. Similarly, Narcissa Malfoy’s love for her son Draco eventually leads her to betray Voldemort, directly leading to Harry’s survival – another oversight on Voldemort’s part. With these examples, the book strongly hints that anybody with the ability to love cannot go as far down the path of evil as Voldemort has done, and it is his complete lack of compassion that makes him capable of what he does.
Selflessness is a concept strongly tied to love in the books. Sacrifice of one’s life for the people one loves is seen in Harry’s case as well as Lily’s. Also, when confronting Wormtail about his betrayal of the Potters, Sirius tells him “You should have died for them! As we would have done for you!
Spellcasting
Spells are the every-purpose tools of a wizard or witch; short bursts of magic used to accomplish single specialised tasks such as opening locks or creating fire. Typically casting requires an incantation, most often in a modified form of Latin (see Dog Latin), and gesturing with a wand. However, these seem to be aids to the will only; wands are in most cases required, but there are indications that sufficiently advanced witches and wizards can perform spells without them. Spells can also be cast non-verbally, but with a wand. This technique is taught in the sixth year of study at Hogwarts and requires the caster to concentrate on the incantation. Some spells (e.g. Levicorpus) are apparently designed to be used non-verbally. While most magic shown in the books requires the caster to use their voice, some do not (and this may depend on the witch or wizard). Dumbledore has been known to do impressive feats of magic without speaking, such as conjuring enough squashy purple sleeping bags to accommodate the entire student population or during his duel with Voldemort towards the end of Order of the Phoenix.
It is evidently also possible to use a wand without holding it. Harry himself performs Lumos to light his wand when it is lying on the ground somewhere near him. Additionally, Animagi and Metamorphmagi do not need wands to undergo their transformations.
Spells are divided into rough categories, such as "charms", "curses", "hexes", or "jinxes". Although offensive and potentially dangerous curses exist in number, three are considered usable only for great evil, which earns them the special classification of "Unforgivable Curses".
Magical abilities
The following is a list of special abilities that a wizard or witch in the Harry Potter universe may have.
Animagi transformation
An Animagus is a witch or wizard who can turn into a particular animal or magical creature at will. This ability is not innate: it must be acquired by magical means. All Animagi must register at a central authority; it is illegal to obtain this ability without registering, although out of the five Animagi described as such in the books (Minerva McGonagall, Rita Skeeter, James Potter, Sirius Black, and Peter Pettigrew), four either never registered before their death or are currently living and unregistered (McGonagall is the only mentioned registered Animagus).
Animagi transformation is one of the few forms of magic that can be performed deliberately wandlessly. One example of this is that, while both Sirius and Peter are left wandless for over 10 years, both retain the ability with supposedly no ill effects. When Animagi transform, the animal appears to be a normal animal. However, during Prisoner of Azkaban, it is noted that Ron's pet rat, Scabbers (later revealed as Peter Pettigrew's animagus form) has lived over twelve years when only expected to live three. Also, an animagus in animal form retains the ability to think like a human, which is the principal difference from being an animagus and being transfigurated into an animal. Also, while in their human forms, both Sirius Black and Peter Pettigrew were noted to look something like their animal forms.
Each Animagus has a specific animal form, and cannot transform into any other animal. The animal cannot be chosen: it is uniquely suited to that individual's personality, like the Patronus Charm, and in most cases the Animagus will change into the same animal used in the person's Patronus charm. (McGonagall's Patronus is a cat, like her Animagus form; James Potter's was a stag, which was also his Animagus form.) Similarly, when an Animagus transforms it is always into the same animal (i.e. same markings, same colours, etc.). When an Animagus registers, they must record all the defining physical traits of their animal form so that the Ministry can identify them.
Explicit emphasis is made in the books on the differences between Animagi and werewolves. Animagi have full control over their transformations and retain their minds, whereas werewolves' transformations are involuntary and include severe changes in personality. After the person has transformed into a werewolf, he no longer remembers who he is; he would kill his best friend if he got anywhere near him. A werewolf only responds to the call of his own kind. The only way that a werewolf can retain his sanity, intelligence and memory while transformed is using the Wolfsbane Potion.
Rowling also makes it clear in The Tales of Beedle the Bard that an animagus is not the same as a wizard simply transfiguring themselves into an animal. The former ability, as mentioned above, allows the witch or wizard to maintain their own mind and human powers of reasoning and memory. The latter however would cause the person to gain the brain of the animal they have transfigured into. This would lead to the obvious problem that they would forget that they were a wizard and be trapped, unknowing, in this form for the rest of that creature's lifespan unless transformed back by another wizard.
Metamorphmagi
A Metamorphmagus (a portmanteau of metamorph and magus) is a witch or wizard born with the innate ability to change some or all of their appearance at will. The talent cannot be acquired; a witch or wizard who has it must be born with it.
Nymphadora Tonks and her son, Teddy Lupin are currently the only known Metamorphmagi in the series; it is a very rare ability, possibly hereditary. Tonks is known to change her hair color and style according to her mood. Indeed, she even appears as an old woman on occasion. Her son, Teddy Lupin, also inherited this trait, as his hair is mentioned repeatedly changing colour.
The extent of these appearance-altering abilities and the limits thereof are not entirely clear. According to Rowling, a Metamorphmagus can alter his or her appearance completely, for instance, from black to white, young to old, handsome to plain and so on. In one example, Tonks changes her facial appearance by reshaping her nose into "a beaklike protuberance like Snape's", to "something resembling a button mushroom", and "one like a pig snout" which reminded Harry of his cousin Dudley's.
Parselmouth
Parseltongue is the language of snakes. It is, in the common mind, associated with Dark Magic (although Dumbledore has stated that it is not necessarily an evil quality), and those possessing the ability to speak it ("Parselmouths") are very rare. It appears to be a skill acquired through both learning or via a method of xenoglossia, such as through genetic inheritance (or by use of Dark or dangerous Magic). Harry was a Parselmouth: it was revealed in Harry Potter and the Chamber of Secrets to be due to Voldemort's passing on some of his abilities to Harry the night he tried to kill him. In Deathly Hallows it is revealed that it is a part of Voldemort's soul within Harry that grants him this ability, which is later destroyed leaving Harry stripped of the ability.
Other known Parselmouths include: Herpo the Foul; Salazar Slytherin and his descendants, including the Gaunts and Voldemort. Dumbledore can also understand Parseltongue; however, he learned it and did not naturally possess the ability. In Half-Blood Prince he repeats Morfin Gaunt's words "the big house over the way", which were spoken in Parseltongue.
Ginny Weasley is not a Parselmouth, although at points in Chamber of Secrets she appeared to speak in Parseltongue: she was at the time being possessed by the spirit of Tom Marvolo Riddle, who was himself Voldemort, a Parselmouth. Ron uses Parseltongue in the final book to reopen the Chamber of Secrets, but only through persistently trying to mimic the sounds that Harry made.
Rowling borrowed the term from "an old word for someone who has a problem with the mouth, like a hare lip."
Flying
Flight without aid of a broomstick or other object is a relatively rare ability. Voldemort can do this without the aid of a broom or carpet, as can Snape.
Objects are also known to be enchanted so they fly. Sirius had a flying motorbike that he lent to Hagrid to bring Harry to the Dursleys, and Arthur Weasley enchanted a Ford Anglia to fly. However, because of a loophole in the law (it is illegal to enchant certain Muggle Artifacts) that Mr. Weasley himself made, he was not technically in the wrong.[ The enchantments cast on these machines do not affect their normal functions and purposes, except the ability of flight.
Seers
A Seer is a witch or wizard with the clairvoyant ability to predict future events. The predictions given through this ability can sometimes be self-fulfilling prophecies, and Dumbledore states in Order of the Phoenix that not all of them come true, depending on the choices made by those mentioned. This would seem to indicate that a Seer predicts possible or likely events, at least in some cases. Sybil Trelawney is noted to never remember that she has made a prophecy when it is a true one. She speaks in a hoarse voice and only if a wizard is present will anyone know about it.
Each prophecy made by a Seer is recorded in a glass sphere and stored in the Hall of Prophecy of the Department of Mysteries within the Ministry of Magic. Only a person mentioned in a prophecy can safely retrieve it; anyone else who tries to do so will be driven insane.
According to McGonagall, true Seers are extremely rare. Sybill Trelawney is the only Seer shown in the books, although it is mentioned that Sybill's great-great-grandmother, Cassandra Trelawney, was a renowned Seer in her day. Trelawney is considered an "old fraud" by her students, and is sacked by Dolores Umbridge in the fifth book for it. However, she has twice made true prophecies (not counting 'minor' predictions such as Neville's breaking a teacup, the death of Lavender Brown's rabbit Binky and Hermione's quitting Divination. It is unclear whether Trelawney's visions of the Grim 'following' Harry in his third year are Sirius Black in Animagus form or just Trelawney being melodramatic and predicting the death of a student as she has done every year).
Legilimency and Occlumency
Legilimency is the magical skill of extracting feelings and memories from another person's mind — a form of magical "telepathy" (although Snape, an able practitioner of the art, dismisses the colloquial term, "mind-reading", as a drastic oversimplification). It also allows one to convey visions or memories to another person, whether real or imaginary. A witch or wizard possessing this skill is called a Legilimens, and can, for example, detect lies and deceit in another person, witness memories in another person's past, or "plant" false visions in another's mind.
The counter-skill to Legilimency is Occlumency (and its user, known as an Occlumens), by which one can compartmentalise one's emotions, or prevent a Legilimens from discovering thoughts or memories which contradict one's spoken words or actions. An advanced form of Occlumency is planting false temporary memories inside an Occlumens´ own head while blocking all other true memories, so if a Legilimens, even a highly skilled one, were to attempt to read the mind he or she would find false memories only and believe everything was right. This is how Snape was able to lie to Voldemort for years.
Voldemort, Snape, and Dumbledore are all known to be skilled in Legilimency and Occlumency. Throughout the books, Snape is repeatedly said to be highly skilled in Occlumency. Voldemort is said to be the master of Legilimency by Snape, as he, in almost all cases, immediately knows during conversations if someone lies to him.
The skills are first mentioned in Order of the Phoenix, (though Harry gets the impression before that Snape can read minds) wherein Snape is instructed by Dumbledore to give Harry lessons in Occlumency. Whether as a result of negligence in Snape's instruction, or poor aptitude on Harry's part, Harry never made any progress in the skill, and as a result he was lured by Voldemort through a carefully calculated vision he falsely believed to be real. Only once has Harry managed to overcome Snape with the use of Occlumency, in Order of the Phoenix. It seems that not everyone is able to master Occlumency. Also, although it appears to be an advanced form of magic, a young wizard can learn to be an Occlumens (Draco Malfoy was able to block Snape's attempt to use Legilimency on him in his 6th year, after being taught Occlumency by Bellatrix Lestrange). Near the end of Order of the Phoenix, Harry learns from Dumbledore that his love for Sirius is what caused Voldemort to release his possession of Harry. Revolting from the love in Harry, Voldemort feared the further use of Legilimency on Harry, drawing away from their connection. This allows Harry to freely see/feel Voldemort's thoughts/emotions in the next two books. In Deathly Hallows, Harry finally does master Occlumency - shutting his mind to Voldemort - when Dobby dies. He realises that his grief - or what Dumbledore calls it, love - is what can block out the Dark Lord.
Bellatrix Lestrange, Draco Malfoy, Narcissa Malfoy and Barty Crouch Jr also have skill in Occlumency, since Bellatrix was clearly said to have taught Draco to shield his thoughts from Snape. It was never clearly said that Narcissa was an Occlumens, but since she successfully managed to prevent Voldemort (the master of Legilimency) from detecting her lie about Harry's death, she is very likely to be one.
Legilimency and Occlumency are not part of the normal curriculum at Hogwarts, and most students would graduate without learning them. They seem to be considered a more advanced form of magic.
Apparition and Disapparition
Apparition is a magical form of teleportation, through which a witch or wizard can disappear ("Disapparate") from one location and reappear ("Apparate") in another. It is sometimes accompanied by a distinctive cracking or popping sound, though this is associated with ineptitude rather than success; the most skilled wizards can Apparate "so suddenly and silently" that they seem to have "popped out of the ground" (Dumbledore). The act is also accompanied by a very unpleasant squeezing sensation, as though being sent through a tight rubber tube, according to Harry.
The Ministry licenses apparition, and a witch or wizard must be 17 years old or older and have a licence to use Apparition in the same way real-world governments require individuals to have a licence to drive a motor vehicle. Students at Hogwarts may attend Ministry lessons in Apparition during their sixth year, and may take their examination once they turn seventeen.
The training is difficult, and students run the risk of splinching — being physically split between the origin and destination — which requires the assistance of the Ministry's Accidental Magic Reversal Squad to undo. Splinching is quite common during lessons, and can be uncomfortable (and at times rather gruesome) depending on the body parts splinched, but is ultimately harmless if properly reversed. Ron left behind half of an eyebrow during his first Apparition exam, causing him to fail, and splinched himself twice in The Deathly Hallows.
For reasons of security, the grounds of Hogwarts are protected by ancient Anti-Apparition and Anti-Disapparition spells, which prevent humans from using Apparition in the school grounds. This does not extend to magical creatures such as house-elves and phoenixes, who can still use their own form of Apparition. It is also possible to prevent individuals from using Apparition, as Dumbledore did with the Death Eaters in Order of the Phoenix, whom he held until Ministry officials could take them into custody.
It is considered rude to Apparate directly into a private area, such as a home. Dumbledore stated in the 6th book that it would be "quite as rude as kicking down the front door". For this reason, and for reasons of security, many homes also have Anti-Apparition spells protecting them from uninvited intrusions. The accepted way to travel to a home is to Apparate near the destination, and continue to the final destination on foot. Apparition is considered unreliable over long distances, and even experienced users of the technique sometimes prefer other means of transport, such as broomsticks.
A wizard or witch can use Side-Along Apparition to take others with them during Apparition. Dumbledore uses this on Harry several times, and notably, Harry uses Side-Along Apparition to take the weakened Dumbledore back from the seaside cave containing Voldemort's locket Horcrux. This was also Harry's first real Apparition outside of lessons and although unlicensed and never before having even tried Side-Along, he does it extremely successfully and later he, Hermione and Ron sometimes Side-Apparate each other as well. In addition, Dumbledore's phoenix, Fawkes, used Side-Along-Apparition to take Dumbledore with him when avoiding arrest from the Ministry. This suggests that phoenixes, like elves, can teleport anywhere, even in places with Anti-Apparition spells (this is also written in "Fantastic Beasts and Where to Find Them"). However, this ability may require more skill than normal Apparition or more concentration at least, as Hermione splinched Ron when she Side-Along Apparated him and Harry in a desperate moment. Dumbledore, who was much older and much more experienced, could Side-Along Apparate people with no problems as shown when he took Harry in this method multiple times.
In the Order of the Phoenix film, Death Eaters and Order members Apparated and Disapparated in clouds of smoke. Death Eaters would appear and disappear in black smoke, Order members in white. In the movie, both sides also seemed to be able to "half-apparate" in which their bodies were made out of smoke, giving them the ability to fly. This is not canon to the books and probably just used for more cinematic, atmospheric purposes. Interestingly, both times Fred and George apparated and disapparated, they did it with a pop as in the books.
It is shown that it is possible to Apparate without a licence; it's just not usually done unless in lessons and is illegal. In this way it seems to be similar to having a licence to drive a car as well: one doesn't need a licence to have the skill, but does need it to use the skill legally. In Deathly Hallows, Harry did not possess a licence, while Hermione and probably Ron did, but he appeared more skilled at Apparating than Ron as he has never splinched himself or others and Ron has splinched himself at least a few times. In the books, it was indicated that while Ron could Apparate, he wasn't very good or skilled at it. He splinched himself at least twice (although both times it was extremely minor) and Harry and Hermione were able to Apparate before he could. When extra lessons were mentioned, Harry had been able to Apparate once in the previous lesson and Hermione had managed it twice and passed her test easily the first time. In contrast Hermione seemed to have no problems Apparating, except the one time when she tried Side-Along and splinched Ron, but she was in a very difficult circumstance then, and managed it perfectly on all the numerous other occasions that she used Side-Along. In Harry's first official Apparition (and the first one of the trio to do it in more than lessons or the test) he not only did not splinch himself, he managed to Side-Apparate Dumbledore and get them both over an unspecified distance on the first try with no problems.
In the books, the words "Apparate" and "Disapparate", like many other neologisms used by Rowling, are capitalised, whereas established English words such as "jinx" and "hex" are not. The words themselves are most likely derived from the French apparaître and disparaître meaning to appear and disappear, although before Charles Fort's invention of the term "teleportation" in the 1930s, it was known as "apportation". Another possible derivation is from the English word “Apparition” meaning to appear suddenly or dramatically, which comes from the Latin "apparitio" meaning attendance. "Disapparate" probably comes from the same word but with the prefix: “dis-” expressing negation or reversal.
Other teleportation
Some other forms of instantaneous movement occur in the books, such as a house elf's ability to teleport or Fawkes's ability to disappear in a burst of flame. (In Fantastic Beasts and Where to Find Them, it is stated that all phoenixes have this ability.) In the novels, Harry refers to this as "Apparition" but this may be because of Harry's inexperience and not fact. This theory is further reinforced as neither Fawkes nor house-elves are restricted by anti-Apparition magic. Fawkes also vanishes silently and in a burst of flame, whereas a wizard Apparating is accompanied by a very loud "crack" (or a quiet "pop") with no visible effect.
Floo Powder is also used to teleport. The wizard/witch takes a small pinch of floo powder and throws it into a fire. The fire will turn an emerald green and the wizard/witch will shout where they wished to go. Harry used Floo powder before and shouted 'diagonally', instead of 'Diagon Alley' and ended up in Knockturn Alley.
Another method of teleportation is by portkey. With ministry permission, an object can be turned into a portkey. A portkey will teleport itself and anyone touching it at a specified time to a pre-chosen destination. Harry, the Weasleys, and Amos and Cedric Diggory take a portkey to the Quidditch World Cup in Goblet of Fire. The Triwizard cup was a portkey that took Harry and Cedric to the cemetery where Voldemort's father was buried. In book five, Dumbledore creates an illegal portkey to take Harry and the Weasley children to Number 12, Grimmauld Place after Mr. Weasley is injured.
In addition, Vanishing Cabinets allow one to teleport, although the only one in the series (first seen in Chamber of Secrets) is initially broken. Only after Draco Malfoy repairs it in the Half Blood Prince can Death Eaters teleport into Hogwarts, bypassing the protections.
Veela charm
An ability attributed to Veela and those of Veela heritage, such as Fleur Delacour. It is used to charm males, much like the Sirens in The Odyssey.
Harry seems more resistant to this than Ron and most others, though the first time he was exposed to it his reaction was similar to Ron's. Men who are exposed to it over time become more resistant to it, although the Veela charm takes full effect if the Veela surprises the man, as noted by Ron in 'The Half-Blood Prince'. It is possible that Victoire Weasley has inherited this ability from Fleur. As no men of Veela descent have been portrayed in the books (although Bill and Fleur have a son named Louis, as well as two daughters), it is unknown whether they would also have this ability.
As shown in Goblet of Fire, Veela hair can be used as cores to create wands. According to famed wandmaker Mr. Ollivander, these wands are a little "temperamental". Since Fleur's contains one of her grandmother's hairs, being a positive familial bond, no inherent problem is seen within this particular wand.
Magical resistance
This refers to a certain degree of immunity against hexes and spells found in powerful creatures such as trolls, dragons, and giants. Hagrid is resistant to certain spells, like the Stunning Spell, due to his giant blood. This type of resistance is not insurmountable; if enough Stunning Spells, for example, are fired at a creature with magical resistance at once, the creature may still be rendered unconscious. Also, wizards and witches can resist a spell with the power of their own sheer will, such as Harry did in book 4, when Barty Crouch Jr. disguised as Alastor Moody tried to control Harry with the Imperius curse and Harry resisted.
Spell-like effects
Unbreakable Vow
The Unbreakable Vow is a voluntary agreement made between two witches or wizards. It must be performed with a witness ("Bonder") on hand, holding their wand on the agreeing persons' linked hands to bind them with magic as a tongue of flame. The Vow is not literally "unbreakable" as the person taking it is still able to go back on his or her word, but doing so will cause instant death. The Unbreakable Vow was first introduced in Half-Blood Prince, in which Snape made a promise to Narcissa Malfoy to protect Draco, with Bellatrix as the "Bonder", as her son attempted to fulfill the Dark Lord's task, and for Snape to fulfill the task if something should prevent Draco from doing it. Another example in Half-Blood Prince occurs when Ron tells Harry how Fred and George tried to make him undertake an Unbreakable Vow, but because of their father's intervention, they did not succeed.
Priori Incantatem
Priori Incantatem, or the Reverse Spell Effect, is used to detect the spells cast by a wand. The spells cast by the wand will emerge in smoky or ghost-like replicas in reverse order, with the latest spell emerging first. It is first encountered in Goblet of Fire when the house elf Winky is found holding Harry's wand. This spell is used to reveal that it was indeed Harry's wand that cast the Dark Mark. In Harry Potter and the Half Blood Prince, it is revealed that the teenage Voldemort murdered his father and grandparents using his uncle Morfin's wand, knowing that, when examined, the wand would incriminate Morfin as the murderer. In Deathly Hallows, Harry feared that a Priori Incantatem spell would be used on Hermione's wand after the Death Eaters had a hold of it. This would reveal that she had accidentally broken his holly and-phoenix-feather wand (with her wand) when a curse misfired and they both narrowly escaped Voldemort earlier. As a result, the protection of the shared cores was lost and, worse still, this would now be made known to Voldemort. During the final duel between Harry and Voldemort, the latter mentions that he knows that the holly and phoenix wand is destroyed, implying that the Priori Incantatem had indeed been performed on Hermione's wand, as they had feared.
Forcing two wands that share the source of their cores to do battle can also cause a more potent form of Priori Incantatem. The tips of the two wands will connect, forming a thick golden "thread" of energy, and the two wands' masters fight a battle of wills. The loser's wand will regurgitate shadows of spells that it has cast in reverse order. This phenomenon occurred during the duel between Harry and Voldemort at the end of Goblet of Fire. Their simultaneous spells (Harry and Voldemort cast "Expelliarmus" and "Avada Kedavra" respectively) triggered the threads, and as Voldemort lost the battle of wills, his wand regurgitated, in reverse order, shades of the spells he had cast with it – screams of pain from torturing various victims, echoes of the people his wand had murdered: Cedric Diggory; Frank Bryce; Bertha Jorkins; as well as Harry's parents. Harry was previously informed by Mr. Ollivander that the holly wand that "chose" Harry was the "brother" of the yew wand that gave him the lightning-shaped scar on his forehead, although the significance of this was not discussed then. Dumbledore later revealed to Harry that his and Voldemort's wands both shared a tail feather given by Dumbledore's pet phoenix, Fawkes.
Dark Arts
The Dark Arts are those magical spells and practices that are usually used for malicious purposes. Practitioners of Dark Arts are referred to as Dark witches or wizards. The most prominent of these is Voldemort, known to them as the Dark Lord. His followers, known as Death Eaters, practice the Dark Arts while doing his bidding.
The type of spells characteristic of Dark Arts are known as curses, which usually cause harm to the target. All, to a certain degree, are in some circumstances justifiable. The motivation of the caster affects a curse's result. This is most notable in the case of Cruciatus: when cast by Harry, angered by the death of his godfather and desiring to punish the murderer, it causes a short moment of pain; as the murderer herself comments, righteous anger does not allow the spell to work for long. When cast by figures such as Voldemort, who desire to inflict pain for its own sake, it causes intense agony that can last as long as the Dark witch or wizard desires. Use of Dark Magic can corrupt the soul and body; Voldemort has used such magic in his quest to prolong his life and obtain great power. Dark Arts also caused Voldemort to look deformed and inhuman, a side effect of splitting his soul into Horcruxes.
According to Snape, the Dark Arts "are many, varied, ever-changing and eternal... unfixed, mutating, indestructible." They also appear to be the most common form of magic used by criminals, while dangerous spells used by others in the books are frequently labelled Dark. In magical dueling, for example, there are any number of spells that may be used to attack, immobilise, or disarm an opponent without causing pain or lasting harm; however, spells such as the Cruciatus Curse or Sectumsempra, judged to be Dark by reliable authorities, wound or seriously distress a victim in some way.
In the Wizarding world, use of the Dark Arts is strongly stigmatised and even illegal; however, these spells are prevalent enough that even before the rise of Voldemort, many schools, (including Hogwarts), taught Defence Against the Dark Arts as a standard subject. Techniques include anti-curses and simple spells to disable or disarm attackers or fight off certain creatures. Some schools, such as Durmstrang, teach Dark Magic. A Dark Arts class was also taught at Hogwarts while it was under Death Eater control.
Unforgivable Curses
The Unforgivable Curses are some of the most powerful known Dark Arts spells. They were first classified as unforgivable in 1717. Used by the books' villains, such as Voldemort and the Death Eaters and in some cases the Ministry of Magic, their use inspires horror and great fear amongst others. The curses are so named because their use is — except by Ministry authorisation — forbidden and unforgivable in the Wizarding world when used on another human or probably any sentient being. The use of any of these spells on another human being is punishable by a life sentence in Azkaban. These curses are thus very rarely used openly. However, in Deathly Hallows, the Unforgivable Curses are used liberally by good characters, ranging from Professor McGonagall with the Imperius Curse, to Harry effectively using the Cruciatus Curse. He also uses the Imperius curse on a goblin and a suspicious Death Eater during their disguised attack upon Gringotts Bank. However, at the time the Unforgivable curses had been made legal. Since the spells are very powerful, their use requires a strong desire to cause the effects, a directed will, and great skill.
It is noted that to perform the Unforgivable Curses, the caster must "mean it". This means that they need to want the effects a fair amount for the effects to last. In Order of the Phoenix, Harry attempts to use the Cruciatus Curse on Bellatrix, but he is drawing only from righteous anger and does not truly 'mean it'. Bellatrix explains that a caster must truly want their victim to suffer, and thus Harry's spell causes her to feel pain for only a moment. Nonetheless, the sheer force of the curse is enough to blast Bellatrix off of her feet.
The use of the Unforgivable Curses was authorised against Voldemort and his followers by Bartemius Crouch Sr, during the First Wizarding War. Shortly after his resurrection, Voldemort names two Death Eaters "killed by Aurors".
The Unforgivable Curses:
- Avada Kedavra (the Killing Curse, used for killing)
- Crucio (the Cruciatus Curse, used for torture)
- Imperio (the Imperius Curse, used for mind control)
