Special Traits

  • Ambush Predator. The grunchlak has advantage on its attacks in the first round of combat against any creatures that go after it in initiative.
  • Echolocation. The grunchlak can’t use its blindsight while deafened.
  • Keen Hearing. The grunchlak has advantage on Wisdom (Perception) checks that rely on hearing.
  • Standing Leap. The grunchlak’s long jump is up to 20 feet and its high jump is up to 10 feet, with or without a running start.


  • Multiattack. The grunchlak makes a bite and claw attack.
  • Claw. Melee Weapon Attack: +7 to hit, reach 10 ft., one creature. Hit: 15 (2d10 + 4) slashing damage.
  • Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 4) piercing damage and the target must succeed on a DC 16 Constitution saving throw or take an additional 11 (2d10) poison damage and become grappled by the creature (escape DC 15). While grappled the creature is also considered restrained.
  • Slake. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature grappled by the grunchlak. Hit: The target takes 36 (8d8) piercing damage. If this damage reduces the target to 0 hit points, the grunchlak kills the creature by draining it completely of blood.


Said to be a foul abomination first born from the womb of a matron vampire on a midsummer’s eve, the grunchlak has since become a species unto itself. At first sight, one might perceive the creature as an overgrown satyr, but closer inspection reveals a leathery hide and the head of a monstrous bat. The grunchlak knows only the hunger it inherited from its ancient mother and the fear it instills upon all who gaze upon it.
