Behemoth, Thalassic

CR 20.00 Magical Beast N Colossal HD 29
Two massive limbs drag the bulk of this whale-like beast's body from the churning waters of the sea.

Sent by the gods to punish those who dwell near the sea, thalassic behemoths scourge ships and other vessels from the waters before turning their attention toward structures and survivors on land. Despite their massive bulk, thalassic behemoths swim incredibly fast and can easily outpace all but the fleetest of ships. On land, they can be more readily escaped, at least by those willing and able to leave homes and belongings behind. Though capable of surviving indefinitely on land and employing a clumsy, seal-like locomotion, thalassic behemoths soon weary of gravity's never-ending drag. They rarely venture more than a mile or two from shore before returning to the comforting buoyancy of the seas.

Thalassic behemoths resemble immense sperm whales in the water, but they can quickly haul themselves ashore using their mighty forelimbs. Tail and limb alike shatter wood and stone with but a single blow, while their jaws gape wide enough to swallow smaller boats whole.

The coming of a thalassic behemoth is typically foreshadowed by a dramatic increase in missing ships, strange tides, and the uncanny sight of sea life purposefully beaching upon shores. Thalassic behemoths generally spend much of their time lurking a few hundred feet below the surface—but legends hold that even greater behemoths, the dread leviathans, dwell in the deepest oceanic reaches.

Universal Monster Rules

Grab
Grab (bite) Ex from Universal Monster Rule
If a creature with this special attack hits with the indicated attack (usually a claw or bite attack), it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply to use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its combat maneuver check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature's descriptive text). Creatures with grab receive a +4 bonus on combat maneuver checks made to start and maintain a grapple. Unless otherwise noted, grab works only against opponents no larger than the same size category as the creature. If the creature can use grab on sizes other than the default, this is noted in the creature's Special Attacks line.
Fast Swallow Ex from Universal Monster Rule
The creature can use its swallow whole ability as a free action at any time during its turn, not just at the start of its turn.
Swallow Whole (4d6+27 bludgeoning, AC 28, 39 hp) Ex from Universal Monster Rule
If a creature with this special attack begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. Unless otherwise noted, the opponent can be up to one size category smaller than the swallowing creature. Being swallowed causes the target to take damage each round. The amount and type of damage varies and is given in the swallowing creature's statistics. A swallowed creature keeps the grappled condition, while the creature that did the swallowing does not. A swallowed creature can try to cut its way free with any light slashing or piercing weapon (the amount of cutting damage required to get free is equal to 1/10 the creature's total hit points), or it can just try to escape the grapple. The Armor Class of the interior of a creature that swallows whole is normally 10 + 1/2 its natural armor bonus, with no modifiers for size or Dexterity. If a swallowed creature cuts its way out, the swallowing creature cannot use swallow whole again until the damage is healed. If the swallowed creature escapes the grapple, success puts it back in the attacker's mouth, where it may be bitten or swallowed again.
Amphibious Ex from Universal Monster Rule
Creatures with this special quality have the aquatic subtype, but they can survive indefinitely on land.
Capsize (DC 25) Ex from Universal Monster Rule
A creature with this special quality can attempt to capsize a boat or a ship by ramming it as a charge attack and making a combat maneuver check. The DC of this check is 25, or the result of the captain's Profession (sailor) check, whichever is higher. For each size category the ship is larger than the creature attempting to capsize it, the creature attempting to capsize the ship takes a cumulative –10 penalty on its combat maneuver check.
Push (water jet, 20 ft.) Ex from Universal Monster Rule
A creature with the push ability can choose to make a free combat maneuver check with a particular successful attack (often a slam attack). If successful, this check pushes an opponent directly away as with a bull rush, but the distance moved is set by this ability. The type of attack that causes the push and the distance pushed are included in the creature's description. This ability only works on creatures of a size equal to or smaller than the pushing creature. Creatures pushed in this way do not provoke attacks of opportunity and stop if the push would move them into a solid object or creature.
Rend (2 claws, 3d6+18) Ex from Universal Monster Rule
If it hits with two or more natural attacks in 1 round, a creature with the rend special attack can cause tremendous damage by latching onto the opponent's body and tearing flesh. This attack deals an additional amount of damage, but no more than once per round. The type of attacks that must hit and the additional damage are included in the creature's description. The additional damage is usually equal to the damage caused by one of the attacks plus 1-1/2 times the creature's Strength bonus.
Trip (tail slap) Ex from Universal Monster Rule
A creature with the trip special attack can attempt to trip its opponent as a free action without provoking an attack of opportunity if it hits with the specified attack. If the attempt fails, the creature is not tripped in return.

If you hit, you can continue to make attacks against foes adjacent to the previous foe, so long as they are within your reach. You cannot attack an individual foe more than once during this attack action. When you use this feat, you take a –2 penalty to your Armor Class until your next turn.

Greater Sunder from Feat

You receive a +2 bonus on checks made to sunder an item. This bonus stacks with the bonus granted by Improved Sunder.

This bonus to damage is halved (–50%) if you are making an attack with an off-hand weapon or secondary natural weapon. When your base attack bonus reaches +4, and every 4 points thereafter, the penalty increases by –1 and the bonus to damage increases by +2. You must choose to use this feat before making an attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage.

Skill Focus (Perception) from Feat

You get a +3 bonus on all checks involving the chosen skill. If you have 10 or more ranks in that skill, this bonus increases to +6.
