Ooze, Suppurating

A sentient pool of blood and protoplasm seeps forward, the thin membrane encasing its form rippling with undulating pustules.

Unnatural Antibodies. Suppurating oozes lurk in horrible, disease-ridden places. These semi-transparent accretions of pus and coagulant are borne from the liquefied remains of victims of a disease called the Seeping Death.

Morbid Liquefaction. The contagion spread by the suppurating ooze is a radically advanced form of liquefactive necrosis and helps the ooze slowly digest its fleshy prey.

Ooze Nature. An ooze doesn’t require sleep.

Amorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing.

Seeping Death. A living creature that touches the ooze or hits it with a melee attack while within 5 feet of it takes 4 (1d8) necrotic damage and must succeed on a DC 13 Constitution saving throw or contract a disease. At the end of each long rest, the diseased creature must succeed on a DC 13 Constitution saving throw or its Dexterity score is reduced by 1d4. The reduction lasts until the target finishes a long rest after the disease is cured. If the disease reduces the creature’s Dexterity to 0, the creature dies and its body becomes a suppurating ooze 1d4 hours later. The disease lasts until removed by the lesser restoration spell or other similar magic.

Spider Climb. The ooze can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.


Pseudopod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 9 (2d8) necrotic damage. If the target is a creature, it must succeed on a DC 13 Constitution saving throw or become infected with the seeping death disease (see the Seeping Death trait).
