Special Abilities

Ooze Nature. The ooze doesn't require sleep.

Putrid Stench. A creature that starts its turn within 5 feet of the corrupting ooze must succeed on a DC 14 Constitution saving throw or take 3 (1d6) poison damage and be poisoned until the start of its next turn.

Actions

Multiattack. The corrupting ooze makes two Slam attacks. If both attacks hit one creature, the target must succeed on a DC 14 Dexterity saving throw or one nonmagical leather, metal, or wooden item the creature is wearing or carrying is destroyed. This effect can't destroy armor or weapons.

Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) bludgeoning damage plus 7 (2d6) poison damage.

Bonus Actions

Reshape Body. The corrupting ooze can reshape its mass into a vaguely Humanoid shape or back into its amorphous shape. It reverts to its amorphous shape if it dies. While in a Humanoid shape, it can take any action that requires hands, except it can't wield weapons or a shield or don armor.
