Spheres of Guile
This tabletop roleplaying supplement expands the use of character skills for exploration, investigation, social encounters, trickery, and combat. Fifteen skill spheres provide customizable talents that enable extraordinary actions, including options normally associated with magic, while guidance on character motivations supports roleplaying and adversarial encounters. Five new classes—the agent, courser, envoy, mastermind, and professional—focus on specialized skill use. Traditions, feats, archetypes, and other options extend these abilities to characters of any class.
