The Inquisition Players Guide is a 144-page hardcover supplement, and the first of two faction-focused supplements for the Imperium Maledictum line. It provides players and GMs with expanded character creation options to generate acolytes and Patrons rooted in the Holy Ordos of the Inquisition. Players can outfit their characters with powerful weaponry and tools from the Inquistion's Armory, such as Daemonhammers, xenos weaponry, spy tools and introducing rules and a bestiary for Familiars. This book introduces the new Subtlety mechanic, a new system for aiding players in espionage-focused games in the 41st Millennium.
