Increases the damage of your Fire spells by 1/2/3% and gives your Flame Orb a 33/66/100% chance to explode for X damage at the end of its duration.
Fire Power is a mage talent talent that increases damage done by fire spells by 1% per rank, up to 3% at max rank 5. This is a multiplicative talent that is applied after the addition of spell damage item bonuses, and is multiplied together with similar talents, buffs and vulnerabilities. As a direct damage boost to all fire damage, this talent is very popular among fire mages.
This damage multipler stacks with other effects that increase damage by a percentage, such as debuffs like Curse of the Elements and other mage talents like Playing with Fire. These percentages are multiplied together when stacking.
