Grimoire : A Personal—& Magical—Record of Spells, Rituals, & Divinations To record her craft, a witch keeps a grimoire. It's a book to chronicle her spells, rituals, recipes, herbs, incantations, and tools—for all the knowledge she has accumulated. A grimoire becomes a sacred text for other witches. Herein lies all of the reference information for your own practice—from lists of lunar phases to popular herbs and crystals. And then you customize to your own will and tastes. Then pass it on for generations to come!
