err.. get 15 max/ed, they are alot more effective, especially if u ahve patients and can afford them. also there are a few with high ed at a low lvl, which can add a shitload more dmg than a 15 max ( my friend found a lvl 20 rec 34% ed jewel, put it in a 5 socket bow, added 13 to max, godly lvl 20 ownage)
