Smuggler Bay is choked with kelp on purpose — a mat thick enough to foul a revenue cutter's screw is worth keeping, and the free companies keep it. Wrackweed is what grows in a kelp bed nobody is permitted to clear. It does not hunt so much as wait for the water above it to be disturbed, and it does not let go of what it takes down, because it has nowhere to take it.

Traits

False Appearance. While the wrackweed remains motionless on the surface, it is indistinguishable from an ordinary mat of floating kelp.

Drowning Hold. A creature grappled by the wrackweed is held beneath the surface. At the start of each of its turns it must succeed on a DC 15 Constitution saving throw or be unable to hold its breath any longer and begin to suffocate. A creature reduced to 0 hit points while held under is stable but cannot regain consciousness until it is brought back to the surface.

Dead Weight. The wrackweed cannot be moved by any effect that would push, pull or slide it while any part of it is in water.

Actions

Multiattack. The wrackweed makes three tendril attacks.

Tendril. Melee Attack Roll: +6, reach 15 ft., one creature. Hit: 13 (3d6 + 3) Bludgeoning damage. If the target is Large or smaller it is grappled (escape DC 14) and pulled up to 10 feet toward the wrackweed. The wrackweed can hold any number of creatures, but no more than two with any one tendril.
