Okay first of all if this method of duplicating is already posted, remove this thread.
If not then listen carefull. What I am going to do now is giving an example if a possible filter, so if u want do to it different and think you know how to just try out. I am dutch so excuse me if my english is bad.
Duplicating
1. Open WPE pro, or if you have it, the modified version so you dont need to use permedit. If you have Vista, run it as administrator. If you dont have the modified version of WPE pro then run permedit and grant WPE pro system privileges.
2. Create a filter like this, and if you know how to just use a different because I know there are more ways to get an equal effect:
------------------------007-008-009-----011-------------------
Search----------------FF---------FF-------01--------------------
Modify-----------------FF---17---FF------00--------------------
Apply the filter and check it. Activate the filter(s).
3. Open World of Warcaft and login. Switch back to Windows. Target wow.exe whit WPE pro. Now enter the world whit your character.
4. Empty your Backpack. Now the upper left slot of your Backpack will be the spot were you put the items you want to duplicate.
5.1 Duplicating Stacks
This is the easiest one. Not that the other way is much harder. Put the stack in the upper left slot of your Backpack. Now use Shift + Rightclick and split one item. Put that one item anywhere else in your Backpack. The stack of items you wanted to duplicate hasnt changed, while you have one extra item. But I have to warn you, these dublicted items cannot stack anymore, making it less efficient to duplicate stacks.
5.2 Dublicating Normal/Soulbound
This one is a little harder. Put the Normal/Soulbound item you want to dublicate in the upper left slot of your Backpack. Different from dublicating stacks, you now put a stack of any kind of stackable items anywhere into your Backpack (not in the upper left slot). Easiest to use is arrows or bullets or food, since these are easy to collect and cheap. Now use Shift + Rightclick and split one item from this stack of stackable items in your Backpack. Put that one item anywhere else in your Backpack. As you can see that item changes in to the item that is located in your upper left slot. This means you duplicated the item. The stack of stackable items in your Backpack has become gray. No worries, just get another stack of stackable items, put these anywhere else than in your Backpack, use Shift + Rightclick and split any number of items. Put those items on the gray stack of stackable items in your Backpack. Now the stack of stackable items in your Backpack have become normal again, and you have a duplicated item in your Backpack.
6. Thats it you have dublicated items. These dublicated items have some weird characteristics though. If you dupe items that are used to exchange for better items, like Tier 6 coins that are used on some servers to buy Tier 6 items (this mostly comes as a reward for donating or voting), these will all, instead of one, disappear when you buy such a Tier 6 item. The best thing you can do is duplicate a Tier 6 coin, then put the original in the Bank, buy a Tier 6 item, and get your coin back at the Bank.
7. Hadnt got much time yet to test what the duplicates do, although I took some time to type this message so they might have more side effects than I expected. Anyways, have fun duplicating items.
Works on
