Descended is an adjective describing the state of a Tier 2 or Tier 3 character. Characters who have chosen to become Evil Tier 2 or 3 characters are called descended, as in, "Many of the descended have Blood Claws."
Demons are unable to accept healing from other characters. Demons must retain Evil Morality (lower than -19) or lose access to their powers.
