Shambling Mound

The shambling mound engulfs a Medium or smaller creature grappled by it. The engulfed target is blinded, restrained, and unable to breathe, and it must succeed on a DC 14 Constitution saving throw at the start of each of the mound’s turns or take 13 (2d8 + 4) bludgeoning damage. If the mound moves, the engulfed target moves with it. The mound can have only one creature engulfed at a time.

Strength Saving Throw: DC 15, one Medium or smaller creature within 5 feet. Failure: The target is pulled into the shambling mound’s space and has the Grappled condition (escape DC 14). Until the grapple ends, the target has the Blinded and Restrained conditions, and it takes 10 (3d6) Lightning damage at the start of each of its turns. When the shambling mound moves, the Grappled target moves with it, costing it no extra movement. The shambling mound can have only one creature Grappled by this action at a time.

The shambling mound makes two slam attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 14), and the shambling mound uses its Engulf on it.

The shambling mound makes three Charged Tendril attacks. It can replace one attack with a use of Engulf.
