Traits
- Necrotic Absorption. Whenever the Amorphous Amalgamation is subjected to necrotic damage, it takes no damage and regains a number of hit points equal to the lightning damage dealt.
- Undead Fortitude. If damage reduces the zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5+the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.
- Heart of a Child. When engulfed players must make a DC 15 Perception check, players who succeed will see the Amorphous Amalgamations heart. They can attempt to strike at the heart, attacks will be at disadvantage. The heart has 15AC and 5HP. If the heart is slain, the Amorphous Amalgamation will be destroyed.
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: (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.
