Renders an object or person invisible
The Invisibility Spell is a charm that renders a target object invisible. It creates a field of invisibility around the charmed object, and thus differs from the Disillusionment Charm, which hides objects by causing them to blend into their surroundings. The invisibility field can be extended beyond the object itself as well, as shown by Fred and George Weasley's invention of Headless Hats, which, when worn, make the wearer's entire head invisible.
This spell may also be used to render wizards and witches invisible; Albus Dumbledore and Lord Voldemort were among those known to be able to render themselves invisible without the aid of an Invisibility cloak.
