Legend
I would reword it thusly:
Frukathka said:Powerful Smiting [General]
When you employ use of a power attack when smiting, you deal additional damage to your foe.
Prerequisite: Strength 12, Power Attack, Smite attack
Benefit: When you make a power attack against a foe you are smiting, the extra damage caused by your smite ability increases by 50%. You may make one powerful smite attack for every four levels you have attained, and no more than once per round.
