Devolution Corruption

From publisher blurb: This installment of the Occult Skill Guide introduces an all-new corruption that catapults its victims backwards through its species evolutionary history. Devolution progresses based upon a victim’s primal indulgences and primitive instincts, and as a creature devolves, they become more and more animalistic until the person they once were vanishes completely. In addition to complete corruption rules and accompanying manifestations, the product features a deep-dive analysis regarding what devolution is and which behaviors and instincts awaken bestial urges, furthering the corruption.
