I got the Head, Body, and Feet while grinding for Battlemage gear on my SMN. Dunno how many runs it was...

But I recently grinded for the Waist, Legs, and Hands on my BRD and literally leveled in nothing other than Brayflox from 32-41. No FATEs, not hunting log, no quests. It took a lot of runs. X_x

But the set is beautiful, so it was worth it in the end. Shame I can't dye it, but oh well.
