(Dinosaur) Ornithomimus

You hear a stampede off in the distance as the ground beneath your feet shake. They flock toward you with startling speed in a bird-like fashion. As you watch them, you notice how much they look like birds running from a predator. As you watch them, you notice they are moving away from you and you relax. Then you notice something drip on your shoulder. You spin around to see what they were running from…

Ornithomimus is one of the more advanced members of a family made up of very bird-like dinosaurs that includes Strutiomimus and Gallimimus. They are smaller than their larger cousins, but move just as quickly over land. They have highly developed foreclaws which are useful for scratching and maneuvering while running.

Combat

Trample (Ex)

When stampeding, a group of Ornithomimus will literally run over anything in its way. They can only effectively trample creatures of two sizes smaller than themselves. This damage is automatic and opponents get opportunity attacks or saves as normal.
