Talk:The Law of Retribution/@comment-5392913-20150513185016

I was just chatting with 2 guys from a squad that actually managed to beat the nightmare raid. They said that they only got past the hijack part because one guy in the squad used a shield drone specter and it caused a bug that opened all the doors at that part of the mission. They got arcane grace as a reward, so I'm guessing the reward for the nightmare raids are a better droprate for all the rare arcanes.
