Hello all, I am playing a Softcore wizard and all I have left to kill is Diablo on Infero. I was wondering if anyone could help me out though. I feel like I could do him now (have only done a couple attempts) but I figured I have 3.25 million gold and I might as well upgrade my gear and make it a little easier. I personally kind of feel like I should buy a new weapon for more damage but I know some of my gear pieces are kind of a low level and wasn't sure if they would be better upgrades, so I was hoping someone here could give me some advice.
