Entangling Form

A creature that touches the Seaweed Elemental or hits it with a melee attack while within 5 feet of it must succeed on a DC 14 Strength saving throw or become Restrained by the elemental. At the start of each of the Restrained creature's turns, it takes 5 (1d10) bludgeoning damage as the tendrils of seaweed squeeze it. The Restrained creature can spend its action to attempt the saving throw again, ending the effect on a success. If the elemental moves more than 10 feet away from the Restrained creature, the effect ends.

False Appearance

If the Seaweed Elemental is motionless at the start of combat, it has advantage on its initiative roll. Moreover, if a creature hasn't observed the Seaweed Elemental move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the Seaweed Elemental isn't ordinary seaweed.

Mostly Clumps

The Seaweed Elemental can move through a space as narrow as 5 inches wide without squeezing.

Actions

Multiattack

The elemental makes two Slam attacks.

Slam

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage plus 3 (1d6) poison damage.

Other data

description

Terrifying tales of seaweed elementals are told in many of the taverns along the Obojiman coastline—sailors wrapped in swaths of green kelp and being dragged to the bottom of the Shallows are a common thread in stories that send chills down the spine. For the most part, the Shallows are clear of kelp, so spotting a seaweed elemental is easy for a vigilant sailor, but for those who wish to explore the underwater realm, a seaweed elemental is a serious threat, especially if one wanders into its domain.
