Amorphous. The muck can move through a space as narrow as 1 inch wide without squeezing.
Amphibious. The muck can breathe air and water.
Illumination. The muck sheds dim, greenish light in a 10-foot radius.
Pollution Aura. Any creature that ends its turn within 5 feet of the muck takes 4 (1d8) poison damage.
Spider Climb. The muck can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Toxic Form. A creature that touches the muck or hits it with a melee attack while within 5 feet of it takes 4 (1d8) poison damage and 3 (1d6) acid damage, and it must succeed on a DC 13 Constitution saving throw or else become poisoned until the end of its next turn. Any nonmagical weapon made of bone, metal, or wood that hits the muck corrodes. After dealing damage, the weapon takes a permanent cumulative –1 penalty to damage rolls. If its penalty drops to –5, the weapon is destroyed.
Nonmagical ammunition made of bone, metal, or wood that hits the muck is destroyed after dealing damage.
The muck can eat through 2-inch-thick, nonmagical bone, metal, or wood in 1 round.
Pseudopod. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) bludgeoning damage plus 13 (3d8) poison damage and 10 (3d6) acid damage, and the target must succeed on a DC 16 Constitution saving throw or else gain one level of exhaustion and become poisoned for 1 minute. While poisoned in this way, it emits a dim, greenish light in a 5-foot radius that makes it impossible for it to benefit from being invisible. When the poison effect ends on a creature, any levels of exhaustion caused by this effect are removed from it.
Split. When a muck that is Medium or larger is subjected to lightning or slashing damage, it splits into two new mucks if it has at least 15 hit points. Each new muck has hit points equal to half the original muck's, rounded down. New mucks are one size smaller than the original muck.
Description
When an ooze accumulates enough toxins and pollution into its form without dying, it can transform into a kind of monstrous poisonous ooze known as toxic muck.
Toxic muck is extremely hazardous to any environment that it occupies. Its mere presence in an area will cause plants to wither, animals to become sick, and the earth itself to become foul and corrupted. The muck will also wander in search of prey to consume, endangering any creatures that are hardy enough to survive the toxified environment that they now inhabit.
Adventurers sometimes hunt toxic muck for the rare poisons that are brewed inside them. Toxic muck that is carefully slain can be harvested using a poisoner's kit.
In settings and worlds with nuclear radiation, a toxic muck is usually a heavily irradiated ooze. This may be instead of or in addition to its normal toxicity.
Ooze Nature. A toxic muck doesn't require sleep.
