Oh impressive!
I got my first RoRG after 6 caches. But I think it still not good enough for my crusader. Need to try this next week. What I'm afraid now, my blessed shield freaking hit everything. That mean, it will hit vast and many more stuff. Sigh.

According to Nevatalist quote on link above

Horadric Caches
Now have an increased chance to drop Legendary items on Torment II - VI

I still prefer to clear on T2 and sometime T3 before this. Since I just happen to know what is "Pity Timer", I shall start trying on Normal Mode.
