I once had a static for this bcnm. We've gone about 15 times in all, and we managed to get 4 rings in that time. Afters some bad runs, we decided to break up after our 6th kill w/o a drop. This bcnm can be a cruel mistress at times. Man but we manage to get 3 astrals in a 5 run period. Those were the days, but as they say, it was time to move on to other runs. Oh and we only died once because we got tired and mistakes were made.
