Combat

Protoceratops are not very aggressive, but because they are the favored prey of larger creatures, they have developed effective defenses. A threatened protoceratops lowers its head and charges, attempting to bull rush an enemy and escape. If it cannot get away, it attempts to charge as often as possible.

Powerful Charge (Ex): A protoceratops deals 2d8+11 points of damage when it makes a charge.

Skills: Protoceratops have a +4 racial bonus on Survival checks.
