Traits

Lightning Absorption. Whenever the shambling mound is subjected to lightning damage, it takes no damage and regains a number of hit points equal to the lightning damage dealt.

Dndbeyond Approval. This feature has no mechanical effect in the Shambling Mound. It merely serves as a feature that makes the stat block "unique" enough for Dndbeyond's standard. Allowing me to share the statblock with you, the community. 

Actions

Multiattack. The shambling mound makes two slam attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 17), and the shambling mound uses its Engulf on it.

Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.

Engulf. 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 17 Constitution saving throw at the start of each of the mound's turns or take 19 (3d8 + 6) bludgeoning damage. If the mound moves, the engulfed target moves with it. The mound can have up to two creatures engulfed at a time.

Description

A shambling mound left unchecked will consume everything around it and eventually grow into an ancient shambler, a huge, monstrous version of the shambling mound.
