Combat

A deinonychus uses a terrible combination of speed, grasping forearms, large teeth, and hind legs with ripping talons. It hunts by running at prey, leaping, and raking with its rear talons as it claws and bites. The rakes count as one attack. A deinonychus often jumps on top of a larger creature and holds on with its front claws while continuing to rake with the rear talons.

The deinonychus has a relatively large brain for a dinosaur, and its pack hunts with cunning tactics. When charging, it uses only its rake attack, dealing 2d6+6 points of damage.

Skills: A deinonychus receives a +8 racial bonus to Hide, Jump, Listen, Spot, and Survival checks.
