Camped the Dark Assassin for varying 3-6 hour stretches over 3 days, maybe 20 hrs total in all. I think I was the only Nub dumb enough to go after an Erud Necro solely for the
shoulders... No sooner did he spawn, than turn around and eat my widdle lvl 42 Necro face! Some buds did come over, and helped me rectify the situation, but it took me far too long for those shoulders. I never did replace them. =]
