Critical Mass

Critical Mass increases the damage done by Living Bomb and Flame Orb spells. In addition, Pyroblast and Scorch will have a chance to make your target vulnerable to spell damage, which increases the critical strike chance against the target by 5% for 30 seconds. The increase in damage, and the chance to apply vulnerability varies depending on the number of points spent in this talent. This incorporates the old functionality of Improved Scorch while applying it to Pyroblast as well as adding a damage bonus to Living Bomb and Flame Orb.
