River Dragon

The River Dragon is a giant lizard, growing up to 30 feet in length (nearly half of that being tail), that is found in the rivers and lakes of the world of Weirth.
These creatures are the undisputed kings of the savanna, at least within a half-mile of any waterway. These lizards are are two-tone brown in color, with rows of black spots along the spine and a pale, cream-colored belly. They have oblong, blunt heads, wider than they are long with wide, pincer mouths for grasping prey (swallow a man-sized creature whole on Bite attack roll of 18+).
These creatures can move very quickly, at least as fast as a horse, for short periods, definitely long enough to run a man down and devour him. Both front and back feet have webbed toes and claws, making them especially deadly in combat, if unable to fit their prey in their mouth immediately.
Typical hunting behavior of the river Dragon is that of the Ambush predator. It will lay in wait in the shallow water near the shore, similar to an alligator, and wait for another creature to approach the water to drink. When potential prey is within about 30 feet of the water's edge, the River Dragon will burst from the water with a shrill, high pitched, keening sound. First they will attempt to rush the prey and catch it in the River Dragon's mouth as it explodes from its hiding place. If the prey is able to flee, the river Dragon will follow at top speed ( ")
The skin, claws and pincer-teeth of a River Dragon are very valuable to armorers and alchemists. A particularly durable type of leather armor can be made from the skin, and it fetches a high price (High Quality x40 modifier). This armor is one step better than standard boiled leather armor, and weighs five pounds less than boiled steerhide.
