Behemoth, Thalassic

CR 20.00 Magical Beast N Colossal
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.

Cleave from Feat

<p class="stat-block-1"> As a standard action, you can make a single attack at your full base attack bonus against a foe within reach. If you hit, you deal damage normally and can make an additional attack (using your full base attack bonus) against a foe that is adjacent to the first and also within reach. You can only make one additional attack per round with this feat. When you use this feat, you take a &ndash;2 penalty to your Armor Class until your next turn.</p>

Great Cleave from Feat

<p class="stat-block-1"> As a standard action, you can make a single attack at your full base attack bonus against a foe within reach. If you hit, you deal damage normally and can make an additional attack (using your full base attack bonus) against a foe that is adjacent to the previous foe and also within reach. 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 &ndash;2 penalty to your Armor Class until your next turn.</p>

Greater Sunder from Feat

<p class="stat-block-1"> You receive a +2 bonus on checks made to sunder an item. This bonus stacks with the bonus granted by Improved Sunder. Whenever you sunder to destroy a weapon, shield, or suit of armor, any excess damage is applied to the item's wielder. No damage is transferred if you decide to leave the item with 1 hit point.</p>

<p class="stat-block-1"> When you use the attack action, you can make one attack at your highest base attack bonus that deals additional damage. Roll the weapon's damage dice for the attack four times and add the results together before adding bonuses from Strength, weapon abilities (such as <i>flaming</i>), precision based damage, and other damage bonuses. These extra weapon damage dice are not multiplied on a critical hit, but are added to the total.</p>

Improved Critical from Feat

<p class="stat-block-1"> When using the weapon you selected, your threat range is doubled.</p>

Improved Iron Will from Feat

<p class="stat-block-1"> Once per day, you may reroll a Will save. You must decide to use this ability before the results are revealed. You must take the second roll, even if it is worse.</p>

Improved Sunder from Feat

<p class="stat-block-1"> You do not provoke an attack of opportunity when performing a sunder combat maneuver. In addition, you receive a +2 bonus on checks made to sunder an item. You also receive a +2 bonus to your Combat Maneuver Defense whenever an opponent tries to sunder your gear. </p>

<p class="stat-block-1"> When you use the attack action, you can make one attack at your highest base attack bonus that deals additional damage. Roll the weapon's damage dice for the attack three times and add the results together before adding bonuses from Strength, weapon special abilities (such as <i>flaming</i>), precision based damage, and other damage bonuses. These extra weapon damage dice are not multiplied on a critical hit, but are added to the total.</p>

Iron Will from Feat

<p class="stat-block-1"> You get a +2 bonus on all Will saving throws.</p>

Lightning Reflexes from Feat

<p class="stat-block-1"> You get a +2 bonus on all Reflex saving throws.</p>

Power Attack from Feat

<p class="stat-block-1"> You can choose to take a &ndash;1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is increased by half (+50%) if you are making an attack with a two-handed weapon, a one handed weapon using two hands, or a primary natural weapon that adds 1-1/2 times your Strength modifier on damage rolls. This bonus to damage is halved (&ndash;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 &ndash;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.</p>

Skill Focus from Feat

<p class="stat-block-1"> 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.</p>

Vital Strike from Feat

<p class="stat-block-1"> When you use the attack action, you can make one attack at your highest base attack bonus that deals additional damage. Roll the weapon's damage dice for the attack twice and add the results together before adding bonuses from Strength, weapon abilities (such as <i>flaming</i>), precision based damage, and other damage bonuses. These extra weapon damage dice are not multiplied on a critical hit, but are added to the total.</p>
