This is the best gun to Transmogrify in World of Warcraft.
To this day IMO. The gun below is one of the coolest I have seen in WoW.
This was during the WOTLK invasion event. Random scourge would appear and you would have to kill them. They dropped purple epics. I managed to get my hands on some. They had a wierd +undead damage set bonus. I'll try to find some SS's of it.
