A sea wasp can entangle a creature up to two sizes smaller than itself with its tentacles with a successful CMB check. An entangled opponent suffers tentacle damage and the effect of its poison each round the hold is maintained. An entangled creature still receives a save to avoid the effects of its poison. While a foe is entangled, the sea wasp cannot attack any other creature.
A monstrous sea wasp can jet backward once per round as a full-round action at a speed equal to four times its swim speed. It must move in a straight line, but does not provoke attacks of opportunity while jetting.
Monstrous sea wasps can automatically sense the location of anything within 60 feet that is in contact with water.
Environment warm aquatic
Organization solitary or ring (2-5)
Monstrous sea wasps are deadly aquatic creatures with long, writhing and highly poisonous tentacles that extend for several yards. They inhabit warm waters and tend to congregate near coastal regions or river mouths where they wait for prey to wash downstream to them. Monstrous sea wasps are also called box jellyfish or marine stingers. Almost invisible in the water, the sea wasp has four eyes, one on each side of the bell, connected to a nerve ring inside the main body. They have no brain, but are able to process visual information. These eyes are invisible to all but the keenest observers.
Monstrous sea wasps feed on a variety of marine life including fish, manta rays and stingrays, and crustaceans. The larger monstrous sea wasps also feed on sharks, whales, giant fish, giant squids, octopi, and swimmers. Prey that becomes entangled in its mass of tentacles is quickly stung by the sea wasp and then coiled into its mouth and devoured.
Monstrous sea wasps are non-aggressive and do not actively hunt for food. They simply float along in the water waiting for a living creature to swim into its mass of tentacles. When it detects prey in its tentacles, it folds them around the prey, and stings it. A monstrous sea wasp’s poison (particularly the larger ones) is meant to instantly kill its prey so it does not struggle and damage the sea wasp’s delicate form. Sages catalogue the sea wasp’s sting as being one of the deadliest and most painful one can experience. A creature stung by a sea wasp that lives to tell about, never forgets its brush with this monstrosity.
