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.

Actions

Multiattack. 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.

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit:13 (2d8 + 4) 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 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.

Lore

A shambling mound, sometimes called a shambler, trudges ponderously through bleak swamps, dismal marshes, and rain forests, consuming any organic matter in its path. This rotting heap of animated vegetation looms up half again as tall as a human, tapering into a faceless "head" at its top.
