Way of the Demon's Bane

Monks of the Way of Demon's Bane follow a tradition that focuses their Ki on soul magic. These monks might be called Demon hunters or fiend foes, and they once were a vital weapon against demonic and devilish incursions. However, the majority of their abilities come from understanding and applying the powers of the abyss against their foes.
