This creature is not a true giant, but is actually a composition of several hundred strands of semi-intelligent seaweed. The weed giant is not rooted and, although it gains food in the manner that regular seaweed does (i.e., through nutrients in the water), it also feeds by entrapping creatures or other plants in its strands and decomposing them with its digestive secretions. The weed giant then absorbs its victim(s) through its strands. In this manner, the weed giant is similar to an aquatic variation of a shambling mound.
Though composed of vegetable matter, the weed giant is an intelligent lifeform; it thinks and acts with the same instincts and drives that many animals do. The brain of this creature is at the center of its weed structure; it is from this point that the strands emanate. In order to kill a weed giant, a successful attack must be made against the creature’s brain rather than against its kelp strands. Attacks made against the creature’s brain are against AC 3; all other attacks are against AC 9, but do not effective hit-point damage to the monster, merely cutting away strands of weed which grow back in full in 1-4 weeks. The brain can be attacked at random 10% of the time (roll this chance before rolling to hit the necessary armor class); because the brain is mobile, it is virtually impossible to attack directly (in a nonrandom fashion).
In combat, the weed giant does 2-16 hp damage on a strike with its weedy appendages (“arms” or “legs”); if the creature misses, the displacement of water forces the victim away from the weed giant (a distance equal to 4-24.) unless a save is made vs. paralysis. This water buffeting can also be employed by the weed giant to deflect any missile fire from any engine smaller than a ballista. However, unless the missiles strike the brain, they cause no damage to the weed giant at all. All edged weapons (except magical) cause only half damage against this creature; blunt weapons cause no damage at all.
