Oh, just throw a brick at the little bastard. He'll duck... Or take it full in the face and laugh because he's an orc and bleeding is funny  ;D<br/><br/>Or we can have witty repartee while flailing about and dying from poison because we can't hit frikkin' swarms with weapons!<br/><br/>Also, Grease covers a ten-foot square; I'm uncertain of the swarms' positions.
