i asked my DM if this combo was valid, and the answewr was a solemn NO
monk /barbarian
the obvious bonuses- high skill pt/hp/save, rage, uncanny dodge, and all the cool monk abil
the idea: he was a barbarian the has killed too many people. He has turned to meditation to find inner peace. but every now and again, he loses control and enters a frenzied rage that blinds him to his actions. whne he recovers, he awakens to a bloody reality where he must lament the dead and repent for his losing control.
what's wrong? a barbarian is chaotic. A monk is lawful.
dont see the problem yet? a barbarian who become lawful loses his ability to rage. a monk who strays from the path no longer can gain any levels as monk...
so I am screwed both ways...
