I can't believe I have to resort to this, but could someone please dupe me this stupid color or something?
I have been trying to farm it for 5 and a half months of periodic but consistent farming. I've gotten white-out...this colors' disparity equivalent for three characters months ago. I've gotten 13, 13 Emperors of various levels over the course of all this time. I've killed these four douchebags on all three difficulties. My Zer0 has almost every customization, no maybe all of them (Barring Portal of course.) EXCEPT the color black.
It took me less time to get a Legendary mod from Vermy (before the advent of the Doctor's Orders guys that seem to drop these somewhat often, go fig), dashboarding to get a Slag Evis rubi, and the Hide of Terramorphous...than it's taken me to get the freaking color black. This has to be one of the most obscene drop rates of anything I've ever come across, and I used to play FFXI. And it's for a color. It's insane.
