Herbivores need to eat plants to survive. Not being designed for combat, they usually have very high health pools. They can output fairly decent damage if they need to defend themselves. And a high amount of stamina to run away if needed. But most attack too slowly. Unlike Carnivores these prehistoric animals cannot eat meat. Herbivore herds are often used to defend themselves together, if a roaming Carnivore gets too close, or decides that a member of the herd will make a good meal.
