Build Guide
This dungeon set is easier than the others, i made it with 2:58 time left -> link
You can swap the the bracers, ring or weapon in the cube, no matter if u don't have the head just complete it with the firebird or whatever you want, only if you have the RoRG, if not just use the head. It's prior to have the off-hand to make easier the task of burn 20 enemies 6 times, just search for a big pull and then use BH to stick them together and channel Disintegrate and the enemies will burn.
For the 50 hits with your revive meteor, just take a big pull running with DS or teleporting like mad sticking at least 50 enemies and let them kill you, and you can hit them with BH and D, maybe you can get 1 counter for the first task.

Thx for the guide, but even with all the gear it was pretty hard at first. But then I changed the following and bam first try:
1) reduced my dps from 1.3 bil to 900k (so the mobs actually have the time to start burning and not die instantly)
2) didn´t use the coe ring (why would you use it? if it procs, your BH just explodes all the mobs and you can´t burn anything)
3) didn´t use bane of the trapped to gather the mobs quicker ( I used 3 defensive gems)
