Traits
Amphibious. The Utopets can breathe air and water.
Slimy Grasp. The Utopets is covered in a slippery, slimy substance. Creatures have disadvantage on ability checks made to escape a grapple with the Utopets.
Luring Presence. The Utopets can mimic alluring sounds, such as distant laughter or cries for help. A creature that hears these sounds can tell they are imitations with a successful DC 13 Wisdom (Insight) check.
Actions
Multiattack. The Utopets makes two Claw attacks.
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target.
Hit: 6 (1d8 + 2) slashing damage plus 3 (1d6) necrotic damage.
Grasping Drown. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature.
Hit: The target is grappled (escape DC 12). Until this grapple ends, the target is restrained, and the Utopets cannot use Grasping Drown on another target. If the Utopets is in water and the grappled target is not a water-breathing creature, the target begins to suffocate after 1 minute if it cannot breathe underwater.
Luring Call (Recharge 5–6). The Utopets targets one humanoid it can see within 30 feet. The target must succeed on a DC 13 Wisdom saving throw or be charmed for 1 minute. While charmed in this way, the target is incapacitated and feels an overwhelming urge to move toward the Utopets, entering dangerous terrain (such as deep water) if necessary. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Lore
Malicious water-dwelling undead originating from criminals or sinners who drowned.
Typically, a Utopets is described as a creature taking the form of a tall, slender human with pale or greenish, slippery skin, a disproportionately large head with disheveled dark hair, and thin, sharp claws on its hands.
Utoptsy are reincarnated spirits of criminals, sinners, or sorcerers who died in water. They usually remain bound to their last place of residence—a pond, lake, or river. They stand as tall as an average person or taller, most often gaunt and bony, with crests on their napes and webbed feet, as well as thin, sharp claws on their hands. Utoptsy have large, bulging eyes on a swollen head with sparse hair. Sometimes they're described with tangled black hair. The monsters are covered in sticky slime that clings to surfaces they've touched. Their skin shows signs of decay, most often greenish or bluish.
