Arcane Blast is a mage ability learned at level 10 for those who have chosen the Arcane specialization. It deals direct arcane damage, generating an [Arcane Charge] each time. So long as one charge remains active, it increases both the damage and cost of the spell. With careful management, the mage can use this spell to trade off damage per mana versus damage per second.
