The Cultist
A character playbook for dark fantasy adventures centered on serving ancient cosmic beings. The cultist can draw resources from a secretive organization, summon monsters, perform dark rituals, and uncover forbidden knowledge. As the character advances, players choose whether to expand the cult’s influence, strengthen summoned creatures, improve ritual magic, or delve further into secrets that may threaten their sanity. The supplement also includes new gear, usable magic scrolls, an ancient tome, two magic items, a related compendium class, four Lovecraftian monsters, and expanded rules for the cult and its abilities.
