Secrets of Pact Magic
This d20 System supplement presents pact magic inspired by medieval Goetian traditions. Spellcasters summon ancient spirits, bargain for their power, and temporarily bind their abilities, often replacing spells with granted powers and side effects. The book includes more than one hundred elemental, epic, and other spirits, each with a seal, legend, ritual, abilities, tactical bonuses, and consequences. It also adds races, base and prestige classes, feats, spells, creatures, magic items, and thirteen organizations, with settings including the Apocryphal Desert, the Ravaged Sea, and the Outer Darkness.
