Durer (5e Creature)
From D&D Wiki
Medium aberration, neutral evil
Saving Throws Str +4, Dex +3
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) slashing damage.
Consume. Melee Weapon Attack: +4 to hit, reach 10 ft., one creature. Hit: 7 (2d6) acid damage, and the target is grappled (escape DC 13). Until this grapple ends, the target is restrained, and the durer can't consume another target.
Swallow. The durer makes one consume attack against a Medium or smaller target it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the durer, and it takes 10 (3d6) acid damage at the start of each of the durer's turns. The durer can have only one target swallowed at a time. If the durer dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement, exiting prone.
Disintegrate. The durer disintegrates into a Large swarm of Tiny worms, which has a burrow speed of 20 feet, cannot attack, has has the Swarm trait, but otherwise is the same creature. If this swarm ends its turn in the space of another durer, it can choose to meld into that durer. This durer effectively dies, and the target durer fully replenishes its hit points. While a swarm, the durer can use its action to return to its normal form.
A mass of black tendrils that have taken on the form of a humanoid being, often lumbers up to its target at full speed to attack, originally a group of elves who had ventured into the far realm and were corrupted—changed—into horrifying beings.
