Devils of Agony and Despair
Habitat: Planar (Nine Hells); Treasure: None
When devils drive hosts of lemures into close proximity or when lemures compress into a single mass, a swarm forms and adopts a unified mind.
The least of all devils, lemures arise from wicked souls, their mortal memories scoured away. Only vague limbs and anguished features jut from these slurries of infernal proto-matter.
Hellish Restoration. If the swarm dies in the Nine Hells, it revives with all its Hit Points in 1d10 days unless it is killed by a creature under the effects of a Bless spell or its remains are sprinkled with Holy Water.
Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through an opening large enough for a Medium creature. The swarm can’t regain Hit Points or gain Temporary Hit Points.
Multiattack. The swarm makes two Vile Slime attacks.
Vile Slime. Melee Attack Roll: +4, reach 5 ft. Hit: 11 (2d8 + 2) Poison damage, or 9 (2d6 + 2) Poison damage if the swarm is Bloodied.
