Increases the critical strike chance of your Flamestrike spell by X%.
Improved Flamestrike was a mage talent that increased the critical strike chance of the Flamestrike spell by 5% per point, up to 15% at max rank. The utility of this talent was directly related to the frequency that Flamestrike is used. Other talents in the fire tree at this tier were usually considered more useful, making this talent fairly unpopular.
