A sargassum fiend is a free-floating mass of intelligent seaweed capable of luring its victims to their deaths via a powerful hallucinogenic pheromone. Once the sargassum fiend lures prey within striking distance, it grabs the entranced creature and attempts to crush it to death. Experienced sailors tell tales of entire crews jumping overboard to swim out to a murderous field of the sea plants.
The strange pheromone produced by a sargassum fiend can be harvested from the numerous bulbs that grow within the fiend’s body, but these bulbs rot quickly once harvested. A fresh bulb lasts for 1 hour before becoming useless; until that point it can be crushed as a standard action to produce a mirage effect as detailed above. A single sargassum fiend generally has 1d6 bulbs of musk when slainâharvesting one requires a DC 29 Survival check. To date, no alchemical or magical process has successfully preserved this musk.
