  • Sunlight Sensitivity. While in sunlight, the gremlin has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
  • Water Breathing. The fuath gremlin can only breathe underwater.


  • Multiattack. The fuath gremlin makes two attacks with its claws.
  • Claws. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) slashing damage.
  • Dart. Ranged Weapon Attack: +3 to hit, range 20/60 ft., one target. Hit: 3 (1d4 + 1) piercing damage.
  • Congeal Water (1/day). One creature of the fuath gremlin’s choice within 30 feet of it must succeed on a DC 10 Dexterity saving throw or be coated with a thick, viscous coating of clinging watery fluid for 1 minute. While coated with this substance, the target is restrained and must hold its breath to keep from drowning (reference the SRD for Suffocating rules). The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.


This small, aquatic, vaguely humanoid creature exhibits keen interest in boaters and beachgoers. Its green, scaly skin and webbed fingers and toes befit its environment, and a thick yellow mane along its spine continues on to its long tail. The playful creature teases and splashes onlookers, ushering them into the water.

This scanty scourge of the sea (and other bodies of water) delights in trickery and causing misery. The size of a newborn human, it is capable of wreaking havoc and even murder. A fuath gremlin will sabotage boats just to watch the fear and mayhem as the passengers cling desperately to life on the open sea.

The evil creature will attempt to drown anyone it entices into the water and can hasten the process by expelling a viscous, suffocating watery liquid from its throat, foiling the efforts of even the best swimmers. It attacks with two claws if close up and dealing with a flailing swimmer or from a distance with darts it fashions from stout underwater reeds and sharpened seashells.
