For any that were doubtful or curious of what it actually spaws on now. I had been told it was comming from either Fezzik or the Cannibal Bringand Mage. Been farming Fezziks for a month now and just got a drop. Top row is in Fel, bottom is in Tram. They pulse lighter to darker and back again. The rest of the facets it seems to remain grey the whole time.
