The Goblin is a basic melee fighter and forms the vast majority of the enemy army. These little creatures are the basic pawns of warfare, and those of low level can be easily destroyed with one shot by experienced defenders. They can have an elemental affinity which protects them from certain defenses and damage. They also have a Challenge dedicated to them, Raining Goblins.
Goblins can be seen piloting or operating mechanical enemies, such as Goblin Copters, and the Goblin Mech.
