I'm level 16 in act 2 and my dark friend has a 2 handed axe that rocks. It wasn't that good in the begining but after a few sharpenings it does 117 to 200 damage. I've put a few points in critical hits and death blows and he can walk through demons, magic users, and archers with one hit!
On the other hand my archer of good only does 46-80 damage with his bow. I really haven't found a great bow yet. I just had a thought - can you sharpen a bow???
