This book puts potency back into omnipotence, the fiendishness into archfiends and takes a huge weight off the shoulders of Game Masters, by providing them a comprehensive set of tools for running these powerful beings. Unleash the Power of the Divine, the Damned and the Devious! In every corner of a fantasy world, unseen forces shape destiny—gods and goddesses, ancient spirits, capricious fey, and scheming fiends. But while their presence is woven into the fabric of nearly every Dungeons & Dragons campaign, Game Masters are often left wondering: What do these powerful beings actually do? The Game Master’s Handbook of Patrons, Pacts & Pantheons is your ultimate guide to bringing deities, supernatural patrons, and religious factions to life. This essential tome provides a wealth of tools, guidance, and inspiration to help GMs craft compelling divine entities, build immersive religious traditions, and seamlessly integrate these forces into storytelling and gameplay. Inside, you'll find: - Worldbuilding Tools – Build rich, dynamic religious traditions and mythologies, from sprawling pantheons to enigmatic cosmic forces. - Patron & Deity Mechanics – Establish divine relationships beyond simple spellcasting, allowing all players to bargain, worship, or defy higher powers. - Tables & Story Hooks – Populate your world with sacred sites, rituals, theological debates, and factions vying for power. - New Supernatural Patrons – From celestial overseers to abyssal overlords, each with unique mechanics to shape their followers’ fates. - Pacts, Gifts & Boons – Create meaningful interactions between mortals and the divine, rewarding devotion, cunning, or sheer audacity. - Four All-New Subclasses – New character options for clerics, paladins, monks and druids, leaning into supernatural patrons who provide the power (and restrictions) associated with each subclass. Whether your players seek the favor of an ancient god, rebel against an oppressive theocracy, or strike a dark bargain with an archfiend, this book empowers Game Masters to weave the divine into every adventure. Will your players ascend to greatness, or become pawns in the eternal struggle of the cosmos? The answer lies in your hands.
