I have spent over a week in Aurum Vale and still no drop. Been averaging 10-15 runs a day to maintain my sanity. Sadly I have completely lost my motivation to do any other content in the game. These repeated runs are sucking the life out of me. It took over 40 runs of Halatali as well before I got the drop. All in all im now 4/16 after 3 weeks of mindless dungeon grind. Don't think i'm done before the next step comes with the new patch...
