Lemure

Magical darkness doesn't impede the lemure's darkvision.

A lemure that dies in the Nine Hells comes back to life with all its hit points in 1d10 days unless it is killed by a good-aligned creature with a Bless spell cast on that creature or its remains are sprinkled with holy water.

Melee Weapon Attack +3 to hit, reach 5 ft., one target. 2 (1d4) Bludgeoning damage.
