Yes, got 4 non mem vouchers under 2 hours and alot of misc. items including 3 blood gems. I think the drop rates are a bit high for this one. Take this with a grain of salt. Maybe they'll nerf it later on because of the increasing players having it.
Btw, stack aquamarines of nulgath by doing the bank stacking glitch and room glitch, it'll make the quests faster. Swap it out every 26-27 drops or else it won't stack.
