From publisher blurb:
Legends say that witches keep their spells inscribed into a Book of Shadows that holds their accumulated wisdom and power.
Here, in Strange Brew: Book of Shadows, you’ll find magic drawn from real-world legends, mythology, and folktales, as well as pure flights of fancy. Within Strange Brew: Books of Shadows, you will find over 100 spells and a half-dozen rituals, enough to delight your characters, bedevil your foes, and make your witch (or other spellcaster, whether arcane or divine) a formidable opponent.
Witches are magical creatures.
