The Disillusionment Charm (incantation unknown) is a charm that disguises a target as its surroundings, not by making it invisible, but by making it take on the exact colour and texture of its environment, effectively turning it into a chameleon.
Hippogriffs and Winged horses may be kept by wizards as long as they perform a Disillusionment Charm on them daily (as their effects are apt to wear off) so that Muggles will not notice anything strange about them. It is also noted that one of the ways to create an Invisibility cloak is to imbue a travelling cloak with a Disillusionment Charm, the charms on these cloaks wear off with time.
During the 1988–1989 school year at Hogwarts School of Witchcraft and Wizardry, fifth year Charms class students were taught about this charm by Professor Filius Flitwick for the Ordinary Wizarding Levels in the subject.
It is presumed that there are two methods of casting. It seems that if one is using the charm on themselves, they must twirl their wand around themselves as though they were wrapping themselves in rope. If, however, they are using it on an external target, they must merely tap on the target with their wand. This then produces a sensation that a raw egg has been cracked onto the person's head as the charm travels down them, granting them invisibility.
|Merula Snyde (possibly)||1986-1987||Used it on herself to spy on Jacob's sibling and Talbott Winger.|
|Albus Dumbledore||1991||Did not need an Invisibility Cloak because he could perform a Disillusionment Charm that was powerful enough to make him effectively invisible without one.|
|Alastor Moody||5 August, 1995||Used it on Harry Potter to protect him during the trip from 4 Privet Drive to 12 Grimmauld Place.|
|Hermione Granger||1997-1998||Used it as part of the protective enchantments used to hide the camp she shared with Harry Potter and Ron Weasley during the hunt for the Horcruxes.|
|Harry Potter||Would occasionally cast the protective enchantments (which included Disillusionment Charms) used to hide the camp he shared with Hermione Granger and Ron Weasley during the hunt for the Horcruxes.|
|Lord Voldemort||Spring 1998||Used it to conceal himself from anyone watching from Hogwarts Castle when he arrived to rob Albus Dumbledore's tomb; the Disillusionment Charm worked so well that even he could not see himself.|
|Vincent Crabbe||2 May, 1998||Used it on himself to hide in the corridor outside the Room of Requirement during the Battle of Hogwarts, which is how he happened to sneak in when Harry, Ron, and Hermione arrived to search for Rowena Ravenclaw's diadem.|
Behind the scenes
- There are numerous portrayals of things being invisible, or else of people appearing noiselessly in the air; both of these may be various instances of this spell being cast.
- While Harry Potter and the Order of the Phoenix claims that this does not induce invisibility but merely camouflages the target, Wonderbook: Book of Spells later states that it does, in fact, cause complete invisibility. This might be a contradiction between two canon sources, or merely a semantic divergence. It's also possible that the charm hides the target as well as the caster intends to, or that only the most powerful wizards and witches can achieve full invisibility.
- As Dumbledore once mentioned that Gellert Grindelwald was able to turn himself invisible without an Invisibility cloak, it is possible that the latter did so through this charm.
