It's hell, I reached 60 before finishing. Gearing, I bought new gear for every slot for all four WDs. But I did say making sure (except for weapons) that I did not spend more than 100k per item. Often I spent 20-50k for a lot of stuff.

Health averaging something like 19k, damage 12k+ i think, about 250% MF on each char with 5 stacks of valor.. enough chances to xxx to lock the enemy and enough regen to keep going.

As I was gearing cheaply, I'm lacking vit and my int stats on items are generally 50-90. It's enough to get started though.. I didn't want to spend too much and find my funds ran out half way through gearing them

I did Diablo after Izual, Diablo couldn't get off a single damage attack and did not summon the black mirror dudes. The most he managed was a cage, which wasn't near me... awesome
