Origin Potion

The Origin Potion is a recipe written in the Book of Shadows.

The potion's purpose is to send a flying energy ball back at its user and destroy his corporeal form.

After adding five mustards seeds, wait five seconds. The potion will erupt in pink goo, then recede and turn brackish green and finally corpse blue. Once the change is finished, add the eye of newt. Let the potion simmer for thirty seconds.

History
The Charmed Ones made one such potion for the Ephemeral Demon, Lupercalus. It was powerful enough to destroy his physical form and banish him into a jar.
