When Leo Wyatt was shot with a poisoned arrow by a darklighter named Alec, he orbed himself to the Halliwell manor. In order to heal him, Piper found this spell in the book and cast it after discussing it with her sisters. When the spell was cast, the sisters discovered that the powers of everyone there had been switched, giving Prue the power to see the future and the past and Phoebe to move things with a wave of her hand. Piper tried to heal Leo, though she could not find the trigger.
