Does the half-orc favored class bonus for brawler improve the damage they do with Close Weapon Mastery as well, or just your actual unarmed-really-unarmed damage (my gut is saying the latter, but I'd be happy to be wrong on this :) )?
It is only unarmed strike damage until you get the class feature which lets you use that in place of the base damage from weapons in the close weapon group.
