To Cloak Oneself in Goodness is a potion that allows the drinker to temporarily fool a force of good and bypass magical defense systems that repels evil, such as a force field.
Description[]
The elixir is a yellowish-green potion that requires a spell and the blood of a good witch, specifically those connected to a specific magical object. Once the blood is added, the potion will smoke and is ready to be consumed.[1]
History[]

Bacarra steals the Book of Shadows.
Future Bacarra acquired Piper's blood for the potion. After present-day Bacarra drank it, they both were able to touch the Book of Shadows without getting repelled and gained access to its magic. They then found a spell to disempower a witch and cast it on the Charmed Ones to strip them of their powers, making them defenseless and open to attacks.
Notes and Trivia[]
- The spell for the potion was never cast onscreen.
