Special Traits

  • Keen Smell. The bog beast has advantage on Wisdom (Perception) checks that rely on smell.


  • Multiattack. The bog beast makes two attacks with its claws.
  • Claws. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) slashing damage. If the target is a creature, it must succeed on a DC 14 Constitution saving throw against disease or become poisoned until the disease is cured. Every 24 hours that elapse, the target must repeat the saving throw, reducing its hit point maximum by 5 (1d10) on a failure. The disease is cured on a success. The target dies if the disease reduces its hit point maximum to 0. This reduction of the target’s hit point maximum lasts until the disease is cured.


This creature appears as a large, shaggy, fur-covered humanoid with clawed hands and feet. Two, long, upright tusks protrude from its mouth. Its eyes are dull brown and its fur is brownish-yellow.

Bog beasts make their homes in bogs and swamps and feed on creatures that dwell there. They are avid hunters and a bog beast’s hunting area usually covers a large expanse of ground several miles around its lair.

A bog beast stands over 9 feet tall and weighs around 1,100 pounds.

It makes its lair amid overgrown swamplands and attacks just about any creature that travels too close to its lair. They seem to be able to communicate with one another through a series of guttural grunts and growls but do not speak any known language.

Bog beasts attack with their claws and always fight to the death. A creature killed by a bog beast is dragged back to its lair, where it is devoured.
