Succubi appear in European legends as demons that take the form of extraordinarily beautiful women. According to ancient beliefs, they visited their victims at night, seducing them in their dreams and gradually draining their life force.

Those visited repeatedly would awaken weaker and more exhausted each time, unable to explain the dreams that haunted them. Over time, the boundary between dream and reality would fade completely, until the victim could no longer tell whether the demon was truly visiting them or whether they had never really awakened at all.

Role in The Black Bestiary
Succubus specializes in hunting Humanoid Beings. When attacking them, it places the Exhausted Condition on them, denying the opponent access to their abilities.
