I thought I would have some luck farming but after about 50 runs of Cave of Shadows I didn't even get a bad pink. I was wearing Bigger Luck the whole time and used a daily elixir. Someone else re-rolled for a Glow Stick but they had a 100% re-roll elixir and did most of the runs. Then in the middle of the runs someone joined and got a Sentinel Shotgun on their first run, no re-roll, then on their second run they got a Glow Stick for a re-roll....
