Special Traits

  • Amphibious. The river troll can breathe both air and water.
  • Keen Smell. The river troll has advantage on Wisdom (Perception) checks that rely on smell.
  • Poison Skin. The river troll’s skin contains a powerful poison. Any time the river troll touches another creature, that creature takes 7 (2d6) poison damage.
  • Regeneration. The river troll regains 10 hit points at the start of its turn as long as it is at least partially submerged in water; strong rainfall also allows the troll’s regeneration to function. If the troll takes acid or lightning damage, this trait doesn’t function at the start of the troll’s next turn. The troll only dies if it starts its turn with 0 hit points and doesn’t regenerate.


  • Multiattack. The river troll makes three attacks: one with its bite and two with its claws.
  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage plus 3 (1d6) poison damage.
  • Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage plus 7 (2d6) poison damage.
