Great Bone-Axe. Melee Weapon Attack: +5 to hit, reach 5 ft., 1 target. Hit: 10 (2d6 + 3) slashing damage damage and 3 (1d6) necrotic damage. one a hit, the target must make a wisdom saving throw (DC 13) or be frightened for one minute. It can repeat this saving throw at the end of its turn.

Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., 1 target. Hit: 6 (1d6 + 3) bludgeoning damage.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 6 (1d4 +4) necrotic damage. The target must make a constitution saving throw (DC 14) or have its hit point maximum reduced by the amount of damage taken by this attack. A target automatically succeeds on this saving throw if they had at least one temporary hit point before taking this damage. The hit point maximum resets after a short or long rest.

Shove. The bloated zombie captain targets one creature within 5 feet of it and tries to shove it or knock it prone. It can not do this while not wearing a shield.
