  • Amphibious. The demon can breathe air and water.
  • Magic Resistance. The demon has advantage on saving throws against spells and other magical effects.


  • Multiattack. The demon makes three attacks: one with its bite and two with its claws.
  • Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage.
  • Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage. If the target is a Medium or smaller creature, it is grappled (escape DC 14). The demon has two claws, each of which can only grapple one target.
  • Ray of Mutilation. Ranged Weapon Attack: +6 to hit, range 30/120 ft., one target. Hit: 7 (2d6) psychic damage and the target must make a DC 14 Constitution saving throw. On a failed save, the target is also cursed with magical deformities. While deformed, the target has its speed halved and has disadvantage on attacks based on Strength or Dexterity. The target can repeat the saving throw whenever it finishes a short or long rest, ending the effect on a success.


Strange waves crossed over from the home of the demons into the ordinary world. These waves corrupted some of the biggest giant crabs and turned them into disgusting fiends.

Sand Crawlers. Although they are usually in the sea, demon crabs also venture onto beaches and other areas around the coast. There have been recent tales of raids on small fishing villages by these horrid creatures.

Evil Eye. The fiend’s large eye can shoot out a bizarre green ray. This magical beam can cause a creature to be mutilated in strange ways. The unfortunate victims are often ostracized when they return to their communities.
