Memory Charm

A Memory Charm is a spell used to erase some or all memories from a person's mind. The incantation is Obliviate.

There are varying degrees of Memory Charms: some only erase one particular memory, such as that which Kingsley Shacklebolt used on Marietta Edgecombe in Harry Potter and the Order of the Phoenix; others completely wipe the victim's mind, such as that which Gilderoy Lockhart attempted to use on Harry Potter and Ron Weasley in Chamber of Secrets. Some powerful Memory Charms can permanently damage the victim's mind. All Memory Charms can be broken by torturing the victim, as Lord Voldemort proved when he tortured Bertha Jorkins after Barty Crouch had put a Memory Charm on her.
