Punishing Kick with weapons?

Question

Ok, so I have a quick question on how the mechanics of the Punishing Kick feat work.

I'm building a duelist that has punishing kick and a rapier as her main weapon. Now do I just add the punishing kick to my normal attacks, or do I need to make an unarmed strike in order to use it?

The rules don't appear to state that you need to make an unarmed attack to have it work, but I could be wrong.

The feat does not explicitly say it has to be an unarmed strike, but I strongly suspect that the intention is that it be only usable on unarmed attacks. Alas, other abilities have weird sounding names, considering how you can combine and use them.

Answer 1

Yes, it is strongly implied that it has to be an unarmed strike. Pathfinder isn't designed to be NP-complete, it relies on reasonable interpretation to work. It's not the letter of the law, but it's the clear intent in my opinion as a Pathfinder GM.
