The 3.5/Pathfinder Handbook

[Mystic Muse]

Power attack isn't gone - it actually gives you bigger returns on your attack roll penalty now. (-1 to your roll gives +3 to damage, if you're using a two-hander) You just can't vary the amount you sacrifice.

And now I'll just shut up because I seem to keep spouting incosistencies or things that I know aren't true. (should have remembered that power attack wasn't gone)

However, I am going to give the edition a chance if this one guy can get back on here.
