Crushing Pressure (Su)

Three times per day as a standard action, a sea giant can increase the water pressure in a 10-foot radius around itself for a number of rounds equal to its Constitution bonus (5 rounds for an average sea giant). Any living creature in the area of increased pressure must succeed on a DC 22 Fortitude save each round it remains in the area or take 1d8 points of damage. The save DC is Constitution-based.

Sea giants are the reclusive cousins of storm giants. They are most often found in the deepest depths of the seas where they make their dwelling in the cones of long dead undersea volcanoes. Sea giants have a druid like power over the forces of the seas, and are a living embodiment of its bounty and destructive wrath. Sea giants seldom come into contact with surface dwellers, but have been known on rare occasions to exact bounties from coastal cities to insure the safety of its navies and merchant vessels. Sea giants are most commonly encountered within a few hundred miles of their lair, tending to their domain and battling off incursions of sahaugin, aboleth, krakens and other such destructive forces of the undersea. An adult male sea giant stands 10 feet tall and weighs about 6,000 pounds. Females are slightly shorter and lighter. Both have sea green skin, dark green or black hair, and silver eyes. Sea giants adorn themselves in loose flowing robes of white, blue, or green. Many wear wreathes of coral in their hair.

When battling at the surface of the seas, sea giants hurl rocks at great length against opposing ranged attackers, usually including crews of siege engines. When battling against surface ships their tactic is to disguise themselves by creating rough waters with their control water ability. They then hammer the hull with their mighty fists until it is holed, without ever revealing themselves to the crew. Once holed, they tear the hull apart and drown the crew. When fighting beneath the waves they use their crushing pressure special ability to increase the water pressure around themselves in an effort to destroy interlopers and trespassers.
