Brawler Archive

I am currently master unarmed. What I mainly use is berserk (75% of the time), stun and unarmedhit 1. Is there a way to decide what type of damage you do? Sometime I lose fights or get in some close ones that shouldnt be because of that. For example, I would still have half my HPs, my opponents would be one hit away from dying, but then the next 4 hits, I will damage action or mind pool, and HPs wont go down.
