Medicinal Cleansing

From: Isabelle
Description: Technically, the Mistress was consuming drinks that substituted reality. In order for this spiteful witch to eat again, I will create the purest water to wash the remnants of the magical painting from her body. Help me prepare a cleansing ritual.
Completed: I pour the drinks from the still lifes into a bowl and dilute them with spring water. Runes flash along the bowl’s edge, and the liquid gradually becomes transparent. The Mistress must consume nothing but this iced water for the rest of the day. Take the drink to her, but don’t expect gratitude.
