Description
Giant Jellyfish are one of the more underrated dangers of the ocean. They float with the currents and the tides nearly invisible (surprising on a 1-4 on 1d6) but moving to attack any creature who passes within 30 feet of the monster.
The attack of the giant jellyfish is a simple one: it drags its trailing tentacles over the body of its victim, and many tiny stingers strike, inflicting both pain and paralysis. Any living creature hit by a giant jellyfish must make saving throw or be paralyzed for 2d4 turns. As this will naturally happen in water, a paralyzed victim may then drown.
A giant jellyfish has 2d10 tentacles per hit die, and 50% of successful hits will be against the tentacles; while each point of damage severs a tentacle, only damage done to the creature's main body counts against its normal hit points. Severing all the tentacles renders the creature harmless, and they will regenerate over the course of a few weeks. Attackers who are aware of these facts may choose to attack the main body specifically, in which case any successful hit will count against the creature's hit points.
