What limitations on Power Attack feat? (very minor KotS pregen spoliers)

[Harr]

I'm almost sure this has been asked before, but I've searched for 20 minutes through google and nothing, so here goes:

The Fighter's Power Attack feat in the KotS pregen. Usable with any attack power, or just with basic attacks? Usable with opportunity attacks?

Also, at third level the fighter gets another daily power. This means he can use each of those powers once in a day, yes? Not that he must choose one of these two for his daily each day or anything like that?

At third level, the fighter gets another encounter power, not daily. And yeah, he can use them both.

Power Attack seems to be useable on any attack, decided at the time of that attack.

You're right sorry, I meant at second level.

But yeah I guess they count as separate powers and he can use them both.. the only one that would have to choose is the wizard because of this 'spellbook' thing.
