Unique quest

Wasted my souls many times, never getting unique items always rare or grade 15 :( game becoming annoying

Use souls only for infinite stamina.Farm on torment 8-9-10 for leg/epic items rank15 & Stones too. When u get enough Stones and good leg items farm unique on inferno stages. In a week i've done from 4M Atk 14 M Def to 20M Atk 38M Def. I'm quite close to start autofarm on inferno stages

Cool .. Right now i'm in inferno level only, but can u tell which stages start giving unique items.
