Ars Goetia

A roleplaying supplement focused on ritual magic, demon summoning, and the binding of spirits to serve a magician. It introduces a Ritual Magician character class, familiars, and rules for the summoning and binding process, along with the powers granted by seventy-two demons from the Lesser Key of Solomon. The book includes demon ranks, sigils, historical-inspired illustrations, an Olde English typography lesson, and a d666 table of consequences for failed rituals or crossing a demon. It is compatible with OSR games, particularly Lamentations of the Flame Princess.
