Bloated Corpse Carrier

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.

Death Burst. When the bloated corpse carrier is reduced to half its hit points (112 HP), it releases a number of Zombie Minions equal to (1d4 + 2). These zombies act on their own initiative and attack the nearest living creatures. The recoil from the death burst causes the Bloated Corpse Carrier to become stunned for 1 turn.

Putrid Aura. Any creature that starts its turn within 10 feet of the bloated corpse carrier must succeed on a DC 17 Constitution saving throw or be poisoned until the start of its next turn.

Multiattack. The Bloated Corpse Carrier makes two slam attacks.

Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 17 (3d6 + 5) bludgeoning damage.

Corpse Vomit (Recharge 5–6). The bloated corpse carrier spews forth a torrent of vile liquid and rotting body parts in a 15-foot cone. Each creature in that area must make a DC 15 Constitution saving throw. On a failure, a target takes 21 (6d6) poison damage. If the saving throw is successful, the target takes half the poison damage.
