I am currently farming act 3 inferno with 5 stacks (siegebreaker and asmodan)
I have 55k hp, get 10k armor, 1100 all resist, 40% block
I use leap iron impact, frenzy sidearm, revenge provoc, warcry with resist, ignore pain with 7 sec,
and WoTB insanity,
use superstition as one of your passive, you do 0 dps when you are dead.
you can switch to berserker rage when you have more survivabiilty.
dps is not that important but 12-15k is optimal.
use a life on hit weapon with fast IAS in order to stay alive, you need at least 700 LoH, it can be from Ammy, rings or wpn.
*Look for all resist gears in the 60s for each gear. the 40s and 50s won’t cut it in Act 3+ inferno.
I hope this helps. I can get 2-3 stacks on Act IV, and should be close to farming diablo with 5 stacks when I upgrade a few piece.
Leave comments or questions, thanks.
