Rancid One (5e Creature)
From D&D Wiki
Medium ooze (oozing one), chaotic evil
Damage Resistances acid
Amorphous. The oozing one can move through a space as narrow as 1 inch wide without squeezing.
Spider Climb. The oozing one can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Stench. Any creature, other than an ooze, that starts its turn within 10 feet of the oozing one must succeed on a DC 15 Constitution saving throw or be poisoned until the start of the creature's next turn. On a successful saving throw, the creature is immune to the oozing one's stench for 24 hours.
Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) bludgeoning damage, plus 3 (1d6) acid damage.
Spit Acid. Ranged Weapon Attack: +0 to hit, range 15/30 ft., one target. Hit: 3 (1d6) acid damage.
When an oozing one dies, its body liquefies, such that its remains become a mass of slime with a vaguely humanoid shape. Dark rituals can imbue these remains with some of the hunger of the Faceless Lord, granting them a new life. Existing in the void between life and death, a rancid one has a uniquely repulsive stench and no desires beyond seeking food, such that it is little more than a common ooze. The only remembrance of a rancid one's former existence is its humanoid shape, though its limbs droop listlessly and its face issues naught but moans of anguish and vitriol.
Ooze Nature. A rancid one doesn't require sleep.
