The animated sludge can enter a hostile creature's space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.
Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (3d6) necrotic damage. In addition, a target hit by this attack must succeed on a DC 15 Constitution saving throw or gain one level of contamination.
Each creature in the animated sludge's space must succeed on a DC 15 Strength saving throw. On a failed save, a creature becomes grappled by the sludge if it is Large or smaller (escape DC 14). Until this grapple ends, the target is restrained. If the saving throw is successful, the target is pushed out of the sludge's space. The sludge can grapple one Large creature or up to two Medium or smaller creatures at one time. At the start of each of the sludge's turns, each target grappled by it takes 28 (8d6) necrotic damage and must succeed on a DC 15 Constitution saving throw or gain one level of contamination. A creature within 5 feet of the sludge can attempt to pull a creature or object out of it. This takes an action and requires a successful DC 14 Strength check.
