The best monk build for DB farming is Sagewuko Firebells.
Sage helm and boots
SWK gloves, shoulders, amulet, chest and pants
Zodiac and Avarice Band
Kyoshiro's Blade and Vengeful Wind
Cube Torch, Tzo Krin's, RoRG
Zei's stone, Hoarder Powerful
You should be able to one shot blue packs and most RG's take two hits, at most three.
What Torment can this build handle, KhordLizardMage?
without tzo krin WoL is too weak.
better to farm t13 is LoN LTK and get 2-3 db every elite kill.
Sage set is useless nowadays
