Duping is very easy. Just follow these step and practice on single player games. Duping also works with hellfire. It is the same way as for Diablo.
Drop the item on the ground that you want duped.
Walk away so you can still see it.
Click on your item
At the exact same time you picked up the item left click on a potion in your belt
Drop the potion
If done correctly the potion should turn into your item that you want duped
What Is Diablo?
Diablo is a great game from Blizzard (the makers of Warcraft and it's sequels). Diablo is being billed as a role-playing game, and in the single player mode it actually is. Although even in Single Player mode it is one of the most basic go kill this and get that type of RPG that most hard core role-players will be put off by it's simplicity. The game is great for introducing those unfamiliar with role-playing to the genre. The Multi-player is where Diablo really shines as a game. It has less quests and come out more as a hack'n'slash type game in Multi-player mode, but the fact that you can interact with others makes it very addictive. The game sports an easy to use interface which most people can handle without even a glance at the manual (although some people should read the section on LATENCY before asking about the bars next to their name). The game sports beautiful SVGA graphics that dazzle the eyes and some really cool sound effects. The music that accompanies the game is very good at setting the mood except for in the town where the volume of that particular tune seems to be extremely high compared to all the other music tracks in the game. The monster death scenes are particularly satisfying as are the dynamic lighting effects. It's nice to be able to shoot a fireball down a long path and get glimpses of what is ahead by using the light it throws off. The game saw many delays in release but was well worth the wait. There are a few known bugs and a few system problems that you should be aware of before running out to buy this great game. Make sure your system has all the current drivers and that they are DirectX v2.0 or 3.0 compatible. Another thing to watch for is the temperature of your system. Diablo is one of the most advanced games on the market and often pushes borderline systems into the overheat range. If you suddenly start experiencing Page Fault Errors and Can't Read CD Errors while playing (even if you just started the game), then try running it with the cover off your case and a fan blowing on it. Most of the time this seems to work. Overall this game is highly addictive and another great product from the folks at Blizzard. Below are the Minimum System Requirements for Diablo.
