Disillusionment Charm

The Disillusionment Charm is a spell that is used to hide something. This spell causes the object to become a kind of chameleon, taking on the appearance of whatever is behind it. It is typically used to hide magical creatures or objects from Muggles. Mad-Eye Moody cast a Disillusionment Charm on Harry Potter to protect him during the trip from 4 Privet Drive to 12 Grimmauld Place. It was also used by the thirteen witches and wizards who came to collect Harry from number four, Privet Drive for the last time in 1997.

When a Disillusionment Charm is cast on a person, the caster taps their wand on the top of the subject's head. Then, it feels as if the caster has broken a raw egg on top of the subject's head. There may or may not be a nonverbal incantation.

The spell is also the most common way to create an Invisibility cloak. It is possible to create such a powerful Disillusionment charm that the targets are completely invisible, as proved by Lord Voldemort and Albus Dumbledore.

Owners of Hippogriffs and all breeds of Winged horses are required by law to cast a Disillusionment Charm on their creature every day to prevent Muggles from seeing them.
