Kelp Strangler

A drifting mat of kelp animated by drowned breath and a patient, bottomless hunger. It lies still among the weeds until something warm wades past, then lashes out with grasping fronds. Once it has you wrapped it simply holds and squeezes, dragging you under to drown while it waits out your struggling.

Kelp Lash: bludgeoning, 15 ft, +4 to hit, 2d6+3 and held. Suffocating Wrap: held target save Con Tough or begins drowning/loses action, cooldown 2 rounds.

Plant Mass: piercing half damage; fire hurts normally if not submerged. Invisible among kelp beds while still. Senses: Night Vision (60 ft), Living Sense (feels the living, 60 ft).
