Learn the hideous secrets and vile rituals of Golarion's most evil cults, from the lord of all devils Asmodeus to the apocalyptic monstrousness of Rovagug. These deities are the villains of the cosmos, sadists and manipulators who view mortal life as a resource at best, or cattle to be fed upon at worst. Yet even the gods of corruption do not directly interfere in the workings of humanity - they leave that to their faithful, a despicable lot who spend their lives in the pursuit of cruelty, trickery, and violence. Faiths of Corruption presents an overview of the evil-aligned religions and faiths of the Pathfinder campaign setting, along with new rules and information to help players customize pious characters in both flavor and mechanics.
