Elasmosauruses are long-necked, primeval reptiles that dwell in deep oceans and seas. Although not truly a dinosaur, elasmosauruses are often found in similar locations and are similarly titanic creatures. Keeping their massive bodies underwater, elasmosauruses use their long necks to catch prey and snorkel air to their massive lungs while remaining mostly hidden from the surface above. An elasmosaurus is 30 feet long and weighs 6,000 pounds. As rare and reclusive as they are, elasmosauruses ar

Abilities

Deep Breath — The elasmosaurus can hold its breath for 2 hours.
Long Neck — An elasmosaurus's long neck allows it to interact with the surface while its body remains submerged underwater. While submerged no deeper than 15 feet underwater, an elasmosaurus can still stick its head up to breathe. An elasmosaurus gains cover against attacks made against creatures who are above the water's surface while it is underwater, even if its head is above the surface.
Attack of Opportunity (Jaws Only) — Jaws only

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.

Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.
Drag Below (attack) — The elasmosaurus attempts an Athletics check against a Grabbed foe's Fortitude DC. If the elasmosaurus succeeds, the foe is forcibly moved 5 feet toward the elasmosaurus's body. If the elasmosaurus critically succeeds, the foe is moved 10 feet towards the elasmosaurus's body.
Thrashing Retreat — A swimming elasmosaurus thrashes the area around it as it attempts to flee. It makes two paddle Strikes, each of which must be against separate targets, and each of which takes the normal multiple attack penalty. It then Swims up to its swim Speed. This Swim does not trigger reactions based on movement.
