Special Traits

  • Keen Smell. The mountain troll has advantage on Wisdom (Perception) checks that rely on smell.
  • Regeneration. The mountain troll regains 20 hit points at the start of its turn. If the mountain troll takes acid or fire damage, this trait doesn’t function at the start of the mountain troll’s next turn. The mountain troll dies only if it starts its turn with 0 hit points and doesn’t regenerate.


  • Multiattack. The mountain troll makes two melee attacks, but can use its slam only once.
  • Kick. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) bludgeoning damage, and if the target is Medium or smaller it must succeed on a DC 15 Dexterity saving throw or be hurled up to 20 feet away.
  • Slam. Melee Weapon Attack: +8 to hit, reach 20 ft., up to three targets no more than 5 ft. apart. Hit: 15 (2d10 + 4) bludgeoning damage, and if the target is Large or smaller it must succeed on a DC 16 Strength saving throw or be knocked prone.
  • Stomp. Melee Weapon Attack: Each creature in a 10–foot-radius burst centered on the mountain troll must make a DC 16 Dexterity saving throw, taking 15 (2d10 + 4) bludgeoning damage on a failed save or half as much damage on a successful one.


Incorporating features of their cave and hill kin, mountain trolls are huge, with thick rocky skin and sparse, mossy hair. Despite their size, they are capable climbers with strong arms and large hands providing them an ample grip in their mountainous home.

Despite the name, mountain trolls often venture into rocky lowlands to hunt, where prey is more abundant and their rough hide still affords them some level of cover.
