Pushing Assault (Combat)Modifier
A strike made with a two-handed weapon can push a similar sized opponent backward.
Prerequisites: Str 15, Power Attack, base attack bonus +1.
Benefit: When you hit a creature your size or smaller with a two-handed weapon attack modified by the Power Attack feat, you can choose to push the target 5 feet directly away from you. If you score a critical hit, you can instead push the target 10 feet directly away from you. This movement does not provoke attacks of opportunities, and the target must end this move in a safe space it can stand in.
Essentia: You Push the target +5ft (+10 ft on a Critical Hit) / Essentia
