Special Abilities:
Improved Grab (Ex): To use this ability, the plesiosaur must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity.
Scent (Ex): This special quality allows the plesiosaur to detect approaching enemies, sniff out hidden foes, and track by sense of smell.
Description:
This nightmarish version of the plesiosaur is a grotesque parody of the prehistoric creature. Its skin is a rugged, scarred texture, hinting at its violent nature and the battles it has endured. Its eyes are dark and intense, exuding malevolence and intelligence. This creature is not just a predator; it's a force of nature, a relic from a time when monsters ruled the world.
Combat:
The plesiosaur is an aggressive and relentless hunter. It uses its speed and strength to overpower its prey, often toying with them before delivering the final blow. Its powerful jaws can snap bones with ease, and its flippers are strong enough to crush or slap opponents with deadly force.
When hunting in the water, the plesiosaur uses its improved grab ability to latch onto prey, dragging them underwater to drown them before feasting. On land, it relies on its bite and flipper attacks, using its size and strength to overpower foes.
Note for GMs: This creature is designed to be a formidable opponent, capable of challenging even seasoned adventurers. Its nightmarish appearance and aggressive nature make it a perfect antagonist for a horror-themed campaign or adventure. Adjust its stats and abilities as needed to fit the desired challenge level for your players.
