Went to use that Diablo trade site to see what boss mats were going for and saw several people advertising 5,000 summons worth of duriel mats for like 40m gold. Thought it was a good deal and contacted the person. When they invited me on a level 1 alt with a gibberish name I immediately felt like I was gonna be buying duped items. Didn’t wanna take the risk so I just blocked that guy from everything. A little later I was watching videos on how to farm boss mats on YouTube and came across a couple videos of people advertising a dupe method which according to them is an old method that apparently cropped back up with VoH.
So I guess all the stacks of boss mats I’ve seen spammed in trade over recent days too have been duped as well?
