Ultimate Onmyōdō

A tabletop roleplaying supplement centered on onmyōdō, an animist tradition in which spirits inhabit rivers, trees, storms, and the dead. Onmyōji act as diviners and intermediaries, seeking spiritual favor and applying the spirits’ guidance to the mortal world. The supplement includes three base classes: the onmyōji, the shikigami ascendant, and the warrior poet. Its systems include petitions that call on spirits, origami folds that grant daily abilities, haiku performances with shifting effects, and talismans that provide persistent targeted or area-based benefits. It also contains archetypes, character and shikigami feats, and options tied to the Seven Lucky Gods.
