A creature within 5 feet of the cube can take an action to pull a creature or object out of the cube. Doing so requires a successful DC 13 Strength check, and the creature making the attempt must make a DC 13 Dexterity check if they fail, or be engulfed..
The dough can use a bonus action to expand to cover more creatures and/or split into multiple pieces.
Pseudopod. Melee Attack: +4 to hit, reach 5 ft., one creature. Hit: Disarms creature and absorbs held item (unless is obviously harmful to creature, like fire, salt, acid, etc).
Coerced Attack. Melee Attack: +5 to hit, reach 5 ft. one creature. Hit: Creature takes 1d4+3 (5) bludgeoning damage.
Engulf. The cube moves up to its speed. While doing so, it can attempt to engulf creatures. Whenever the cube uses this action, the creature must make a DC 13 Dexterity saving throw.
On a successful save, the creature can choose to be pushed 5 feet back or to the side. A creature that chooses not to be pushed suffers the consequences of a failed saving throw.
On a failed save, the creature's space, and the creature is engulfed. The engulfed creature can't breathe. It can only hold its breath for half its Constitution modifier in minutes . (minimum 1) due to carbon dioxide production When the dough moves, the engulfed creature moves with it.
An engulfed creature can try to escape by taking an action to make a DC 13 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the cube.
