Yeah, I'm going to have to disagree with that. Strongly. I mean, never power attack if you have less than a 95% chance to hit? What a waste of a feat. Anything you can already hit with 95% certanity you can probably kill with your minimum damage anyway.cordell said:5) If your highest bonus attack doesn't have enough bonus to hit on a 2, then never power attack.
Personally I like a 40%-60% chance on my primary after taking into account penalties from PA and such. Though in this case you are talking about someone who is also TWF which makes the secondaries more valuable so he may want slightly better odds (like 50%-75%). In any event I still say always power attack for at least one or two points unless you know that you are going to need absouetly everything you got to hit the guy (meaning you have a 10% or 15% chance before adding in penalties).
Power attack is one of your basic feats. It is how full BAB types stay compettitive at higher levels. Use it.
