Yes, it does!!

Yeah, they could be all fake, but come one, thats Highly unlikely!
I've personally never looted the foxtail myself. I probably killed the black vixen 50 times plus. If you do a quick google search you cannot find anything useful other than a couple of images. I want to just share what I've seen as this picture was on reddit from a character by the name of Fenis Dael. Also this item is still listed as very rare on wiki so I mean it must be super rare. I hope someone can share their experience with the black vixen for now I havent looted a foxtail as I'm truly unlucky lol.
