Tehialai-Thief-of-Ships

This sense allows a monster to feel vibrations caused by movement through a liquid. It's an imprecise sense with a limited range (listed in the ability). Wavesense functions only if monster and the subject are in the same body of liquid, and only if the subject is moving through the liquid.

At the beginning of each day, Tehialai can molt to change the morph of her two massive striking claws. She chooses two morphs and adds their Strikes and Release Claw effects to the stat block presented here. Tehialai can molt two different claws or two copies of the same claw.

Tehialai hides within a shell made of all the ships she has stolen. This ship armor reduces any damage Tehialai takes by an amount equal to its Hardness. Once Tehialai is reduced to fewer than half her Hit Points, or immediately upon being damaged by a critical hit, her ship armor breaks, removing her Hardness and reducing her Armor Class to 32.

Tehialai attempts to capsize an aquatic vessel of her size or smaller that she's adjacent to. She must succeed at a DC 33 athletics check (reduced by 5 for each size smaller the vessel is) or the pilot's Sailing Lore DC, whichever is higher.

Requirements Tehialai is adjacent to a broken ship, and her ship armor is broken

Tehialai claims nearby ship pieces to rebuild her home. She destroys the adjacent ship and rebuilds her ship armor, restoring her Hardness and increasing her AC back to 36.

Requirements Tehialai's claw isn't currently Pressurized

Tehialai draws water into the base of one of her claws, building immense hydraulic pressure as she prepares to attack. The claw remains loaded until she Releases that Claw or 1 minute has passed, whichever comes first. While the claw is Pressurized, Tehialai can't use that claw to Strike. If Tehialai isn't at least partially within a body of water when she Pressurizes her Claw, she takes a -2 penalty to any attack rolls and DCs when she Releases that Claw.

Requirements Tehialai has Pressurized a Claw

Tehialai lashes out with the force of the sea. See each claw for its released effect; the DC for any effect is 33. After Releasing a Claw, the claw depressurizes.

Requirements Tehialai has Pressurized a Claw

Tehialai's spear shoots out, impaling prey and reeling them back. All creatures in a 40-foot line take 8d6 piercing damage (DC 33 reflex save); creatures that critically fail are Grabbed until the end of Tehialai's next turn. After Releasing a Claw, the claw depressurizes.

Requirements Tehialai has Pressurized a Claw

The impact of Tehialai's claw begets a burning vacuum. Tehialai makes a boiling club Strike against one target within 15 feet. If she hits, a shock wave booms out, dealing 3d6 fire damage and 3d6 sonic damage to all creatures except her within 15-foot burst, including the target itself (DC 33 fortitude save). If the Strike was a critical hit, the target uses the degree of success one lower than it rolled on its save. Unlike most fire abilities, this ability can be used underwater, and the typical 5 fire resistance for being underwater doesn't apply. After Releasing a Claw, the claw depressurizes.

Tehialai launches a flurry of darts. She makes two salt dart Strikes against two different creatures. Both attacks count towards her multiple attack penalty, but she doesn't increase her penalty until after she has made both attacks.

Tehialai atomizes the water in her claw to create a mist that fills a 40-foot emanation centered on her and that lasts until the end of her next turn or until dispersed by a strong wind. All creatures within the mist become Concealed, and all creatures outside the mist become concealed to creatures within it. Wavesense functions through the mist and ignores the concealment.

Tehialai's claw whirs and spins to cut through armor and ship hulls. Tehialai makes a toothed shredder Strike. On a hit, the target becomes Off-Guard until the end of Tehialai's next turn and takes 2d12 bleed.
