The 3.5/Pathfinder Handbook

[Saph]

What Power Attack was used for in 3.5 no longer exists in Pathfinder.

Sorry Jaron, this is wrong. Like I said, I'm in a Pathfinder campaign, and Power Attack is used for pretty much the same thing as it usually is used for in 3.5 games, ie "Take a small penalty to hit something harder." The only time it's an issue is if you only ever used Power Attack in Shock Trooper builds or similar, which most people don't do.
