These three the arrows and the axe do no damage. Basically I just have to throw the axe to build up my rage, then I can take out about 1/4 health bar from an enemy. Then rinse and repeat. The problem is this one fight takes place on a tower that has two cairns that are easy to get stuck on when dodging, so it's hard to keep dodging for 15 minutes without getting pushed to that side of the tower at some point, and then you roll backwards and you're stuck by the cairns.
