I was in act3 up to Cydea for about 2 weeks, but wanted to finish before 1.05 hits. Took down Azmodan last night, and finished act4 today.
Only really scary moment was getting caught in one of Diablo's bone cages with 50% life. Proc'd SV and was cursed with the curse that drains life or something. I had to run around with 216 regen per sec trying not to die, running out the timer on SV. My shadow roll was nice too, spiders and grasp of the dead.
Still took nearly 25 minutes to finish him. I started with 5nv and it was about 45 seconds from expiring when he finally went down.
