Platecarpus

Creature 3 — animal

The mid-sized platecarpuses are the most common type of mosasaur. They're typically 15 feet long, but larger specimens can grow up to 20 feet. The larger varieties sometimes eat Medium humanoids, but most stick to smaller fare. The massive swimming reptiles called mosasaurs thrash their powerful tails to propel them after prey. Four articulated, webbed paddles let them precisely steer their paths, and their hinged jaws-much like a snake's-allow mosasaurs to swallow larger creatures than their s

Swallow Whole (attack) — Medium, 1d6+2 bludgeoning, Rupture 10

The monster attempts to swallow a creature of the listed size or smaller that it has grabbed or restrained in its jaws or mouth. If a swallowed creature is of the maximum size listed, the monster can't use Swallow Whole again. If the creature is smaller than the maximum, the monster can usually swallow more creatures; the GM determines the maximum. The monster attempts an Athletics check opposed by the grabbed creature's Reflex DC. If it succeeds, it swallows the creature. The monster's mouth or jaws no longer grab a creature it has swallowed, so the monster is free to use them to Strike or Grab once again. The monster can't attack creatures it has swallowed.

A swallowed creature is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The swallowed creature takes the listed amount of damage when first swallowed and at the end of each of its turns while it's swallowed. If the victim Escapes this ability's grabbed condition, it exits through the monster's mouth. This frees any other creature grabbed in the monster's mouth or jaws. A swallowed creature can attack the monster that has swallowed it, but only with unarmed attacks or with weapons of light Bulk or less. The swallowing creature is Off-Guard against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the swallowed creature cuts itself free. A creature that gets free by either Escaping or cutting itself free can immediately breathe and exits the swallowing monster's space.

Effect: Engulf and Swallow Whole

If the monster dies, a swallowed creature can be freed by creatures adjacent to the corpse if they spend a combined total of 3 actions cutting the monster open with a weapon or unarmed attack that deals piercing or slashing damage.
Grab

WORKS WELL WITH

AnvilAQUATICA durable front-liner keeps attention while the platecarpus lines up a swim-by Strike against a less protected target.
SniperAQUATICA ranged attacker can keep pressuring it while it's occupied trying to swallow a grabbed target.
WeaverAQUATICA debuffer lowering Fortitude saves raises the odds the swallow attempt sticks against a chosen target.

PUNISHES

✖ isolated targets✖ melee reliance✖ low Fortitude
Water-locked in practice with only a minimal land Speed; pairing with land-only allies limits how much it can contribute once combat leaves the water.
