Here it is, from the Pathfinder SRD:<br/><br/>Brawler: While raging, the barbarian is treated as if she has Improved Unarmed Strike. If she already has the feat, her unarmed strikes deal 1d6 points of damage (1d4 if she is Small).<br/><br/>As he already has Improved Unarmed Strike, I took that to mean all his unarmed strikes while raging are increased to 1d6+6 (Assuming it's a two-handed strike).<br/><br/>[Updated Damage Roll]: 1d6+6= 7 (http://elliquiy.com/forums/dicebot.php?r=21004)<br/><br/>Actually turned out less than the first roll, but I'd say the 1d6 for all other strikes is a worthy trade off!
