I ran through almost all of Act 3 last night.

I went from Keeps Depths Level 1 to Kill Azmodan. About 2 bags worth of rares each guy.

I used Acid Rain, Hex, Big Stinker, BBV Rain Dance. Hex was really useful, and the pets actually stayed up on a lot of fights, they were really handy.

It went pretty well, maybe 1 or 2 repairs. I didn't actually kill Azmodan though, that fight seemed to take forever.
