Single-Dupe
Start up a new filter and leave it in the standard mode. Under SEARCH enter: FF __ FF __ 01 in slots 007, 009, and 011 (the __ indicate unmodified slots). Under MODIFY enter: FF 17 FF __ 00 in slots 007, 008, 009, and 011.
Now log into your character. Put whatever you want to dupe in the upper left slot of your backpack (must be that slot, must be backpack) and then place stacked items anywhere else in the bag. Also place one different stacked item in another bag. Now, enable the filter and shift-click one of the stacked items in the backpack, keep the quantity at 1, and place it somewhere else in the backpack (must be in the backpack). Ta-da, you have a duped item. Now the item you “unstacked” will be greyed so go to that stacked item in the other bag and unstack some quantity of it and drag it on the greyed item thereby un-greying it and letting you repeat this. The stacked items in the backpack can be anywhere except for the first slot, and you can have as many slots occupied as you want for efficiency’s sake.
Notes: This will work on any soulbound or otherwise item, anything. However, reagents duped in this manner will not count toward crafting, or quests (normal quests anyway) - the reason has to do with the mechanics behind this (it shouldn’t take much time to figure it out if you look at the filter, think about what you’re doing, and especially if you drag a duped item onto a bar...). It’s a real shame soulbound trade got disabled as far as I know, because this paired with that... oh man, good times. Also because of the way this works, you can’t stack duped items that would otherwise be stackable but it’s still useful (for instance dupe yourself full Primal Mooncloth bags off of one bought with the gold hack, then keep one bag full of say... Flasks of Petrification - pain to make but if you have one original... bingo). Right, on that note, you can’t dupe from an item duped in this method (again obvious if you understand what the filter is doing) so make sure to keep “originals” in order.
Anyway, I said this won’t count towards completing ‘normal quests’. Well, it so happens that on WoWscape they invented this new GM reward token system with some quests where you turn in tokens of differing quality for different items, namely mounts and non-combat pets. There are also quests to convert a certain number of lesser tokens into greater tokens. It turns out that with the way these custom quests were done... this dupe DOES work towards the completion of those quests, so with a single of the lowest-quality tokens in hand just dupe 20 of them, toss the original in the bank, convert to a higher quality, dupe 20, toss the new original in the bank, convert, and actually that’s the end. Sadly they don’t have an exchange quest for the highest quality token, but you can get everything beneath from one lowest-quality token. I think that about covers it for this one.
Ich denke, das dürfte auch für den ein oder anderen von euch interessant sein.
