  • Amphibious. The shrroth can breathe air and water.
  • Magic Resistance. The shrroth demon has advantage on saving throws against spells and other magical effects.
  • Innate Spellcasting. The shrroth’s innate spellcasting ability is Charisma (spell save DC 16, +8 to hit with spell attacks). It can cast the following spells, requiring no material components:
  • Jet Burst (recharge 4-6). As a bonus action, the shrroth moves up to 80 feet through a body of water. This movement does not provoke opportunity attacks.


  • Multiattack. The shrroth makes one Trident attack and up to four Tentacle attacks.
  • Trident. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 18 (2d10 + 7) piercing damage.
  • Tentacle. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 13 (1d12 +7) bludgeoning damage and the target is grappled (escape DC 19) by the shrroth. The shrroth has six tentacles and can only grapple up to six creatures at a time. A creature that starts its turn grappled by the shrroth suffers 9 (2d8) bludgeoning damage. Each tentacle has an AC of 20, 15 hit points, and immunity to poison and psychic damage. Severing or destroying a tentacle deals no damage to the shrroth and severed tentacles regrow at a rate of one per day.
  • Sickening Cloud (recharge 5-6). The shrroth emits a cloud of grayish liquid into a body of water that fills a 40-foot cube and remains for 2d4 rounds. Any creature that begins its turn within the cloud must succeed at a DC 19 Constitution saving throw or be poisoned for one minute.


Swimming through the fetid backwaters of the River Styx as it flows through the bottomless sea rifts of the Abyss comes a tentacled horror known in the nightmares of marines and sailors. Shrroth sometimes pass through the thin barriers between the mortal realm and the underworld. They quickly set up shop along sea lanes where they harry sailors, sink ships for sport, and take prisoners whom they torment and torture mercilessly before devouring them body and soul.

Shrroths are 15-foot-tall demons with the lower torso of an octopus and the upper torso of a copper-skinned humanoid. Its arms end in six-fingered talons, and it wields a wicked trident. A mass of long black hair hangs from its head. Two forward-curving, blackish horns protrude under this tangle of hair. Its lower torso sports a mass of writing tentacles reaching lengths of 10 feet. Six larger tentacles stretching 20 feet surround the smaller tentacles. The creature’s mouth is a jagged wreck of sharks teeth.
