You can't use them together anyway, its either Power Attack or (Improved)Expertise.KaiRal Windspar wrote:Nope. Won't use it. I use Power Attack, and the combined -15 to attack would be stupid.
You have to pick and chose your moments, sometimes it is better to go for a quick kill rather than tanking it out with Expertise on. Don't forget that a natural 20 will hit whathever your AC, and if you are surrounded by a lot of critters these will start taking an effect.
Sometimes Power Attack is better (or even Improved Power Attack *sighs dreamily*) ! Then again, sometimes it is not, using Power Attack will reduce your chances of a crit (because you are at -5 to AB).
Experience and practise will tell you when to use what.
