There already seems to be some kind of Pot hack/Upgrade hack going on in Dungeon Fighter as of late and it is assumed that the Chinese gold sellers are the cause of this. They hack the pots, get a large amount of unique items, selling them for more than players can afford so they have to go and buy gold from their store just to purchase them. They're also upgrading them to +12, which is suppose to be pretty high and almost hard to find. (Not anymore) They're all over the place selling for 100+ mil.
