Your knockbacks really send people flying.
Prerequisite : Str 25, Power Attack, Improved Knockback
Benefit: Your knockbacks throw your targets a number of squares equal to 1/5th your damage roll (i.e., the total damage, in feet).
Normal: Knockback causes victims to be flung a number of squares equal to 1/10th the damage of the knockback attack (i.e., a number of feet equal to half the damage).
NB: You can apply this feat to the power Energy Attack if you take the Knockback enhancement. You do not need Power Attack or a Strength score of 25.
