Way of the Samurai
A Pathfinder campaign supplement for Kaidan, a setting of feudal Japanese horror, focused on samurai characters and their place in the world. It details samurai clans, honor, seppuku, religious beliefs, character traits, feats, archetypes, orders, and two prestige classes, including options for gunslingers, paladins, rangers, samurai, and wizards. The supplement also provides rules and guidance for creating custom samurai clans, along with the fully detailed modular town of Kawashi. Characters can serve noble lords, defend against supernatural threats, pursue martial or scholarly traditions, or navigate the duties of honor and courtly life.
