Special Traits

  • Fire Hazard. When the ooze takes fire damage, it bursts into flame. The ooze continues burning until it takes cold damage or is immersed in water. A creature that touches the ooze or hits it with a melee attack while within 5 feet of it while it is burning takes 5 (1d10) fire damage. While burning, the ooze’s weapon attacks deal an extra 5 (1d10) fire damage.
  • Sticky Situation. A creature covered in the ooze’s tar has its speed halved for 1 minute. In addition, the tar ignites if touched by a source of fire or if a creature covered with tar takes fire damage. The tar burns until a creature takes an action to snuff out the flames. A creature that starts its turn covered with burning tar takes 10 (2d10) fire damage. A humanoid that dies while covered in tar rises 1 hour later as tar ghoul, unless the humanoid is restored to life or its body is destroyed.


  • Multiattack. The tar ooze makes two pseudopod attacks. If both attacks hit the same target, the target is covered in tar (see Sticky Situation).
  • Pseudopod. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage plus 14 (4d6) necrotic damage.
  • Hurl Tar. Ranged Weapon Attack: +2 to hit, range 60 ft., one target. Hit: 14 (4d6) necrotic damage and the target must succeed on a DC 14 Dexterity saving throw or be covered in tar (see Sticky Situation).


A pool of black pitch bubbles on the ground. Skulls and bones rise to the surface with each burst of putrid air. The tar lets out a burbling hiss, as if releasing the last gasp of a creature trapped within it.

Necrotic Sludge. When a group of tar ghouls is destroyed near each other, the tar sometimes coalesces into a necrotic sludge. Driven by the hunger and hatred of the ghouls, the resulting ooze preys on the fearful.

Ghoulish Allies. Tar oozes view tar ghouls as allies and don’t attack them. Tar ghouls often keep tar oozes as pets or guardians to their underground lairs. Occasionally, a tar ghoul gets the idea to build an army of tar ghouls by feeding humanoids to its pet tar oozes, but infighting quickly dismantles any organization the tar ghouls manage to create.

Eternal Flame. The tar that makes up the ooze is never consumed by fire, and it burns forever. It is prized as an alchemical component for making torches that never extinguish.

Ooze Nature. A tar ooze doesn’t require sleep.
