There are so much potential about air spell that weren't developed here. We can use air spells to knock enemies into wall or suck them together as vacuum force, dealing damage and stun them. We can use vacuum as insulated armor in order to reduce fire and ice damage. We can induce air into fire spell and amplify the damage. We can use "wind cut" to assist melee. We can simply use air to blow away that annoying smoke created after using fire blast. I wish someone develop more about air spell man. They are so cool to be left inadequate like this
