SPECIAL ABILITIES
Grab (Ex) A sargassum fiend can grab Huge or smaller
foes, and has a +8 racial bonus on grapple checks
rather than the normal +4 bonus most creatures with
grab possess.
Mirage (Su) 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 18 Will save or
become enraptured by the scent. An enraptured
creature sees the monster 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. The extent of this
illusion functions as mirage arcana (CL
equals the sargassum’s CR), but is a mind-
affecting phantasm, not a glamer. This effect
ends immediately if the plant makes an attack against any
target. The save DC is Charisma-based.
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 slain—harvesting
one requires a DC 29 Survival check. To date, no alchemical
or magical process has successfully preserved this musk.
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,
up to Colossal. Such enormous sargassum fiends can be
created by advancing their Hit Dice by a minimum of 5 HD
per size increase step.
