Though you may have multiple casters in your empire, there is only one store of mana that they all use to power their spells. Your decisions to use your mana to enchant your champions, attack your enemies, move around the world or guard your cities will be critical to surviving in the world of Elemental. Your sovereign provides a small amount of mana each turn, but there is more to be found by building shrines on the world's mana shards. Spells with maintenance costs like enchantments, city enchantments, and summons will detract from your mana each turn. Click on the mana symbol in the main screen to get a breakdown on where your mana is going; or to dispel enchantments you no longer need.
