Ooze, Corrupting

A corrupting ooze boils and bubbles with rank marsh gas and the fetid stench of the sewer, and it leaves a stinking trail of acidic slime wherever it goes.

Swim and Walk. A corrupting ooze is a festering slime that can slither and even swim like a gigantic sea slug, or it can assume a roughly humanoid form and shamble through the streets, though its stench and its lack of speech make it unlikely that anyone might mistake it for a normal person. They are frequently soldiers and servants to heralds of blood and darkness.

Dissolve Bones. A corrupting ooze can absorb an entire large animal or small person, simply dissolving everything including the bones in a matter of minutes. This function makes them an important element of certain dark rituals.

Corrupting Touch. When a corrupting ooze scores a critical hit or starts its turn with a foe grappled, it can dissolve one leather, metal, or wood item of its choosing in the possession of the target creature. A mundane item is destroyed automatically; a magical item is destroyed if its owner fails to make a successful DC 16 Dexterity saving throw.

Strong Swimmer. A corrupting ooze naturally floats on the surface of water. It swims with a pulsating motion that propels it faster than walking speed.


Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) bludgeoning damage plus 3 (1d6) acid damage, and the target is grappled (escape DC 13).
