Special Traits

  • Water Vulnerability. If the demon ape begins its turn with at least half its body submerged in a body of water must make a DC 20 Constitution saving throw. On a failed saving throw, the demon ape’s size is reduced by one step, from Gargantuan to Huge, or Huge to Large, to a minimum of Tiny. When this occurs, the demon ape deals half damage with all of its abilities, its maximum hit points are reduced by 20 for each reduction, and the size which the demon ape can grapple with its Claw attack is reduced by 1 step as well. The demon ape’s size returns to normal over the course of 1 month.


  • Multiattack. The demon ape makes one Bite attack and two Claw attacks.
  • Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 7) piercing damage.
  • Claw. Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit: 20 (2d12 + 7) slashing damage, and the target is grappled (escape DC 20). The demon ape can grapple 1 Large or smaller creature in each claw.
  • Deafening Roar (3/day). Creatures that can hear the demon ape within 120 feet of it must make a DC 18 Constitution saving throw. On a failed saving throw, the creature takes 4d10 + 5 thunder damage and is deafened for 1 minute. On a successful saving throw, the creature takes half damage and is not deafened.
  • Fling. One Large or smaller object or creature grappled by the demon ape is thrown up to 60 feet in a random direction and knocked prone. If a thrown target strikes a solid surface, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 20 Dexterity saving throw or take the same damage and be knocked prone.
