Rend Ship As a full-round action, a kraken can attempt to use four of its tentacles to grapple a ship of its size or smaller. It makes an attack roll opposed by the ship's captain's skill check, but the kraken gets +4 bonus on the check if it is a larger size category than the ship is. If the kraken grapples the ship, it holds the ship motionless; it can attack targets anywhere on or within the ship with its tentacles, but can only attack foes on deck with its free arms and can't attack foes at all with its beak. Each round it maintains its hold on the ship, it automatically inflicts bite damage on the ship's hull.
