While individually one of these fist-sized jellyfish is merely a nuisance, in great numbers, fire jellyfish can form into dangerous swarms. Bobbing in the water, they create a cloud of stinging tentacles. They were named in part for their bright coloration, but those who are stung by fire jellyfish learn the larger reason for their name—the pain of their stings is comparable to being burned alive.

Abilities

Swarm Mind — This monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.
Agile Swimmer — Fire jellyfish swarms use Acrobatics to Swim.
Burning Swarm (poison) — Each enemy in the swarm's space takes 3d8 poison damage (DC 24 Reflex save) and is exposed to fire jelly venom.
Fire Jelly Venom (poison) — Saving Throw DC 24 Fortitude

Maximum Duration 6 rounds

Stage 1 Clumsy 1 (1 round)

Stage 2 Clumsy 2 (1 round)

Stage 3 Clumsy 3 (1 round)

✖ clumping✖ melee reliance
Waterlocked: this swarm cannot leave AQUATIC terrain, so land-only allies can't fight alongside it in the same space.
