A sargassum fiend emits a powerful scent that causes specific, miragelike hallucinations. All creatures within 300 feet of a sargassum fiend must make a DC 16  Wisdom  saving throw or become  charmed  by the scent. A  charmed  creature sees the sargassum fiend as whatever would most compel it to approach. This might be a lost loved one, a child in need of  help , an enchanting mermaid, the promise of dry land, and so on. This effect ends immediately if the sargassum fiend makes an  attack  against any target. \n'b'  Water Breathing .

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. Sargassum fiends usually reach sizes up to 10 feet in diameter before splitting, their means of asexual reproduction. Mutations have been known to exist, however, and sea-faring scholars have recorded individual sargassum fiends reaching masses of truly enormous  size .'
