Special Traits

  • Amorphous. The chaos beast can move through a space as narrow as 1 inch wide without squeezing.
  • Destabilize. A creature that touches the chaos beast or hits it with a melee attack while within 5 feet of it must make a DC 15 Constitution saving throw or be poisoned for 1 minute. A creature poisoned in this way takes 21 (6d6) necrotic damage at the start of each of its turns. It can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If the creature’s saving throw is successful or the effect ends for it, the creature is immune to the chaos beast’s Destabilize for the next 24 hours.


  • Multiattack. The chaos beast makes two claw attacks.
  • Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage plus 10 (3d6) necrotic damage. The creature must make a DC 15 Constitution saving throw or be affected by the chaos beast’s Destabilize effect.


This creature resembles a lion with dark, blackened fur, razor-sharp fangs, and oversized paws that wield sharpened claws.

A beast of chaos is a creature that has been warped when the demonic forces of the Abyss reach into the Material Plane. A beast of chaos vaguely resembles the animal it once was. Its skin and fur become leprous and patchy. Its color fades to a dull sheen. Its teeth become razor-sharp and more pronounced. Its eyes turn to a bright golden yellow.
