The Assassin: A Modular, Momentum Maneuvers Base Class

This tabletop roleplaying game base class centers on an assassin who builds and spends momentum during combat. Techniques generate or consume different amounts of momentum, creating choices between saving power for a stronger maneuver and using smaller effects immediately. Some techniques also draw from a replenished daily pool. At first level, players choose two combat-focused and two out-of-combat ability trees, shaping the character without using traditional archetypes. The available options cover touch attacks, brutal melee tactics, ambushes, mage hunting, infiltration, heightened intuition, and custom poisons. The supplement includes 105 techniques across seven categories and 19 feats.
