Senmurvs are experts an diving into combat for deadly strikes before retreating to safety. They typically strafe an opponent a few times before closing into melee. When they do, they latch on with both claws and rend, dealing terrible damage.

A senmurv can carry a rider and gear weighing no more than 200 pounds. Senmurvs do not tolerate saddles well, so the rider must learn to do without.
