Tuatha's Grimoire is a grimoire created and owned by the powerful evil witch Tuatha. The Grimoire was entombed along with Tuatha by the Chosen One two hundred years ago. Just like the Warren Book of Shadows, it is known to contain spells and potion recipes, although much of its content is unknown. This Grimoire is not known to possess any magical powers like the Book of Shadows and the Grimoire do.
