TP Modifier (fTP) is a multiplier of your Base Damage on the first hit of a weapon skill. The TP modifier function is a straight linear equation between the anchor points at 100% and 200%. It is also a straight linear equation between the anchor points at 200% and 300%. In other words, each percentage point of TP past an anchor point (100% or 200%) will increase fTP by 1% of the difference between the fTP of the next anchor point and the fTP of the previous anchor point.
