Memory Spell

The Memory Spell is the name given to a spell written in the Book of Shadows that gives witches the ability to give back a person's memories.

History
After Leo Wyatt became an Elder, he used his powers to remove Piper's pain. However, when he was trapped on Valhalla, the spell caused her to become increasingly chipper and less like herself. Her sisters became worried, so Paige cast the memory spell, which backfired and caused Piper to lose her memories completely.
