Special Traits

  • Amphibious. The river troll can breathe air and water.
  • Keen Smell. The river troll has advantage on Wisdom (Perception) checks that rely on smell.
  • Regenerate. The river troll regains 12 hit points at the start of its turn. If the troll takes fire damage, this trait doesn’t function at the start of the river troll’s next turn. The river troll only dies if it starts its turn with 0 hit points and doesn’t regenerate.
  • Siege Monster. The river troll deals double damage to objects and structures.


  • Multiattack. The river troll makes three attacks: one with its bite and two with its claws.
  • Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit:10 (1d10 + 5) piercing damage.
  • Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit:16 (2d10 + 5) slashing damage.
  • Drown. When a river troll hits with a claw attack it can attempt to grapple the target and drown it (DC 16 Strength saving throw). Because of its size, the river troll can attempt to drown two Large or smaller targets at the same time.


The river troll is an absolutely massive type of troll. These huge trolls make their homes in lakes and rivers. They hunt for prey and will attempt to drown their victims. Unlike other trolls, these monsters refuse to serve anyone else.

At Home in the Water. Although they are huge in size, river trolls are actually quite good swimmers. They are also amphibious and use this trait to surprise their victims. River trolls can hide on the bottom of large rivers or lakes for hours.

Deadly Drownings. These horrid monsters are extremely strong and can usually drown their opponents. River trolls can also do extensive damage to objects and structures.

Fears Fire. Attacking the river troll with fire is the only way to stop them from regenerating.
