  • Highly flammable. Bog corpse bodies are often preserved in peat or tar deposits, and their very flesh is imbued with these substances. A bog corpse that suffers fire damage is lit on fire and suffers 3 (1d6) fire damage at the end of its turn. While on fire, a bog corpse inflicts an additional 2 (1d4) fire damage to anyone it hits with its Fist attack, and those who strike the flaming corpse with a melee attack while within five feet suffer 1 fire damage.
  • Watery Grave. A creature reduced to 0 hit points by a bog corpse is not dead. Instead, it falls into a coma that lasts until the bog corpse that reduced it to 0 hit points is slain, after which the victim becomes stable as if it had passed three death saves. If a creature in a coma caused by a bog corpse is placed in the sacred bog the corpse guarded, that creature becomes a bog corpse in 1d6 days.


  • Fist. Melee Weapon Attack: +5 to hit, reach 5 ft., 1 target. Hit: 7 (1d8 + 3) bludgeoning damage and the target is marked by the bog corpse. The bog corpse or any other bog corpse from the same sacred bog gains advantage on attack rolls against a marked target. Furthermore, they can detect the presence of a marked creature within 30 feet, and they know the approximate location of the marked creature if it is farther away.


Created by foul magics of long-dead gods, bog corpses are the remains of victims sacrificed to these otherworldly entities in times long before history began to be recorded. Cursed by the rituals that consigned them to a fetid tomb, bog corpses protect the sacred places in which they died. Once their unholy sites are disturbed, they rise to drive off the intruders and also to hound them to death. Those slain by a bog corpse are not entirely dead, and the bog corpse attempts to carry its victims back before the soul departs its body. Once interred in the rotting bog, the fresh corpse transforms into a bog corpse.
