Special Traits

  • Amorphous. The jelly can move through a space as narrow as 1 inch wide without squeezing.
  • Spider Climb. The jelly can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.


  • Pseudopod. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) bludgeoning damage plus 14 (4d6) acid damage.


  • Split. When a jelly that is Medium or larger is subjected to lightning or slashing damage, it splits into two new jellies if it has at least 10 hit points. Each new jelly has hit points equal to half the original jelly’s, rounded down. New jellies are one size smaller than the original jelly.


Ochre jellies are animate masses of protoplasm hued a sickly combination of yellow, orange, and brown. At rest, their flat, pulsing bodies stand roughly 6 inches tall and can stretch out to a wide diameter-in motion, they often ball up into quivering spherical shapes and almost seem to roll as they move. Their malleable bodies allow them to seep through cracks and holes far smaller than the space they fill. Creatures dwelling below ground often attempt to seal up any such cracks to fortify their lairs against ochre jellies.

An ochre jelly’s highly specialized acid only dissolves flesh. This discovery has led many poisoners and hack alchemists to search out specimens for their tinkering. Some specialized weapons have resulted from these experiments that target the living body in wicked ways. Rumors of a slow-release poison that breaks down the cellular walls in living creatures surfaced a few years ago, but its creator guards the secret with his life.

Notes in a long-forgotten tome mention a burial practice used in faraway places that resembles cremation. Instead of burning the corpse to ashes, the practitioners seal the body into a stone sarcophagus with an ochre jelly so it can dissolve the body. Afterward, the morticians place the ochre jelly into a large canopic jar, complete with a bronze plaque naming the deceased. This practice protects items entombed with the body (which is quickly reduced to nothing but a polished skeleton), and the creature’s essence, it is believed, still rides along with the living jelly.

Ochre jellies stand about 6 inches tall, spread out to a little over 10 feet in diameter, and weigh upward of 2,600 pounds. When in combat, they tend to pile up upon themselves and exude long, dripping pseudopods to slam and grapple anything that moves.

Although the typical ochre jelly has stats as presented here, in the deepest reaches of the underground world these mindless predators can grow to enormous sizes. Perhaps more disturbing, though, are rumors of ochre jellies that have developed additional methods of capturing prey. Adventurers speak of jellies capable of poisoning foes with a touch or exuding clouds of noxious gas that burns the eyes and throat, leaving those who draw too near helpless as the immense protoplasmic beast slithers over their bodies and begins to feed.
