Engulf in Ooze

Actions

Engulf in Ooze. The gelatinous cube moves up to its speed and can enter Large or smaller creature's spaces. When it enters a creature's space, that creature must make a DC 12 Dexterity save. The save is made at disadvantage if the target is unaware of the cube, and automatically fails if there is no nearby unoccupied space.
On a failure, the creature takes 10 (4d4) acid damage and is Engulfed. A creature that is Engulfed is Restrained, Suffocating, and cannot cast spells with Verbal components. It takes 10 (4d4) ongoing acid damage at the end of each of its turns. It can spend an Action to make a DC 12 Athletics check to escape the engulfing creature.
