Actually, I forgot how much extra damage you get from strength (especially from Overhand Chop), and that you used Power Attack (which should be +6 for you, with a -2 penalty to the attack roll).  So, I get +23 to damage.<br/><br/>I do think your total attack bonus is a bit high though, but I might also be missing something.  I'm getting +8 from strength (with rage), +6 from BAB, +1 from +1 weapon, +1 from weapon focus (+16 total), but -2 for a huge weapon (normally -4, the bracers negate 2 of it), and -2 for power attack, so +12 total.<br/><br/>You still hit and cleave the guy in two, but I want to get this settled for future attacks.<br/><br/>As for the damage being too high... possibly.  You're limited to only one attack/round with vital strike though, and you get -2 to attack and -4 to damage if you're not raging, so I'm not going to limit it right now.  We'll see.
