Hopefully this might help out a bit.
I think I have the Brute's damage stat's incorrect. I believe they should be "1d10+9; 1d10+6 when not raging". If power attacking, the damage goes to +12 (with a -1 on the To Hit).
They shouldn't. The statblock in the scenario seems to be the already raging barbarian (increased Will, decreased AC), so the printed 1d10+6 is already raging.
If his statistics are those of a non-raging human, he would require 36 points via point-buy system. This would by VERY unusual.
I don't know what the usual way to handle things is on pfsprep - I suppose it's frowned upon if I just fix it and upload it too, right?
Just about to run this for the first time, and forgot I hadn't gotten my stat ducks in a row. This helped a lot!
