The Bruiser (Base Class)

From publisher blurb:

Classes that focus on unarmed attacks seem to rely on the standard goto Monk class with its oriental flavor. The Brawler takes it a step closer to a traditional pugilistic theme, but still relies on the standard monk abilities including flurry of blows and AC bonus. The Bruiser offers another version of a head bashing brute that relies on his hands to take out his opponents, focusing both on unarmed attacks and grappling.
