Assassins of Porphyra
This roleplaying supplement expands the world of Porphyra with information on its major assassin orders and a new Porphyran Assassin class. It presents more than ten Assassin Secrets, including arcane and shadow-focused options, along with favored class bonuses for core-book races and five new skill uses. The supplement also includes a sample first-level professional assassin and explores assassination as a specialized pursuit involving planning, infiltration, and targeted violence rather than simple combat or theft.
