Two hostile tribes call Oros their home, Udam and Izila, and they both cause their share of trouble for the Wenja. The Udam are proficient with poison while the Izila have mastered fire. They both possess the same types of enemies: Warriors, Archers, Hunters, Spearmen, Slingers, Scourges, and Chieftains. All but the Chieftains have two versions, regular and elite. Typically Elite troops are the same as their counterpart but with head armor that must be broken before you can get a headshot. Their attributes differ slightly between the two clans, but their roles basically remain the same.
