Do push limit affix only add damage on skill not on basic attack?
Push the Limit increases the cost and damage of spells by +50%.
if you have 20 points in a skill, like twister, then basic attack x skill x push the limit, or 1 x 2 x 1.5 = 3. if your basic attack does 1 million damage, then your attack would do 3 million damage. and if your spell cost 500 MP to cast, then it would now cost 750 MP to cast.
basic attack would be (((BWD + Power) x (IQ x WD%) + WD+) x ED%) + ED+ =.
skill points are next, unless they come right after BWD + Power, and then any other multipliers for damage. critical damage is calculated last.
hope this helps.
