Hello, I've recently decided that my I/L archmage is likely to be my (main) character to train, and I've been wondering about gear and how to cost effectively be a modest AM.

These are my current stats



Right now I'm using a Legendary Kage, (115 M.attack +4Int) and I have been wondering if an elemental staff 4 would be worth the money dropped on it.

Assume right now I hit 25k a hit on CL each hit, non crit, if I were wearing a clean 118 Magic attack non potential ES4, How much more damage would I hit?
