As you can see, I have the skull of dire ahamkara equipped (or I do if you're looking at this any time within a day or two after I post this, I'll leave it equipped for a while as evidence). So... I have it. It's the Y2 one. Just bought it off Xur. It didn't appear on my Exotic wall though, so I can't scrap it knowing I can re-buy it later (it's good that I decided it was wise to always verify they show up before scrapping them!)
