I ran Grasp of Avarice through on my warlock on master difficulty, making that the first clear on my account, normal or master. During the first clear of each encounter, I got an artifice piece to drop. Specifically, boots from ogre, chest from 2nd encounter, and helmet from final boss. Now, on subsequent runs of the dungeon, armor will NOT drop. I have ran: 8 master final boss encounters. All 8 dropped 1 Luna. Double drops were NOT working for my character on master. 6 master Ogre encounters. All 6 dropped matadors. I suspected something funny, so I ran through on normal: 1 ogre checkpoint dropped a matador. 1 final boss checkpoint dropped 2 lunas. I then held the final boss checkpoint on normal for 2 subsequent runs: 2 runs dropped 4 lunas. Edit: The 2nd encounter will not drop ANYTHING, weapon or not, on 3 subsequent runs. (For some reason, double drops are working on normal). I was looking forward to farming artifice armor before season 21, as this seems to be the only dungeon dropping decent rolls, but this cant be RNG related at this point. Please help!
