Instructions
Specialize your Talent Tree points into the "Fire" tree. A Fire Mage specializes in dealing damage quickly and efficiently by maximizing the output of his damage, at the cost of some survivability.
Acquire gear that increases "Intellect," "Wisdom" and "Critical Hit Rating." These three stats increase the damage your magic spells do and how often you can cast them, which is essential to maximizing your damage per second.
Use skills that deal high burst damage. Skills that use burst damage perform maximum damage immediately after casting, rather than burning an enemy and damaging him over a longer period of time.
