Eisen pulled his head to the side and managed to dodge the incoming arrow that Brody shot at him. Of course they were blunt arrows, but it still would have hurt if he had been hit right in the center of the face, not to mention that it still would have caused a considerable amount of actual damage to his HP.
But at the same time, that was one of the few ways for Eisen and Brody to cause enough damage to each other to make 'giving up' viable. After all, this was the last type of fight they would go through for the day, and both of them were a little bit tired at this point in time.
