Clerics are part of the same elegant race as that of Archers. They too have the ability flight as an innate attribute. They can heal, curse and can call on the elements of thunder and wind to do their bidding. They can even raise fallen comrades in battle.
They are a good match for closed combatants since their long ranged spiritual prowess complements the short range of melee warriors, which in turn balances the Cleric's inadequacy in physical attacks.
