My friend who said he had gotten it from blizzhackers before they took it down said..
He downloaded it..
Installed it like Maphack..
Put the item you wanted to dupe in the cube with a nagel ring and a perfect skull..
then click transmute..
and he also said, that you need space in your INV for the item you are wanting to dupe if you dont you will get realm down..
He also also ^^ said that they took it down from blizzhackers shortly before he got it.
That's all i know about it so far, i hope we can get it to work
