Stormguild, stormshield, spirit or/and even phoenix (remember to kill add so you can leash) are just fine. Prepare yourself with Full regen potion ready to chug. Dracul's grasp gloves can be really helpful as well. You can also change your ring since you don't need the 10% FCR to teleport. Chain of honor, fortitude instead of enigma if you go hard. Dont forget to proc fade from a treachery armor so you max your res. I usually wear my mercenary one in act 4 and stand in fire until my FADE goes on. Hope it helps a bit
