Rusty Hearts [EU] Augment Stone Increasing

[Gpof]

You need two (2) Magic Chest of Change, 3 stones and another player to trade to. You have to trade the other player and then Ctrl+Right click on the Magic Chest of Change, a small window will appear asking you how many MCoC (Magic Chest of Change) you want to trade, ignore that small window and don't close it. Now drag one stone and drop it on the MCoC then right click on the stone (to add it into the trade) do the same for the other two stones. Trade them and the receiver should get 6 stones instead of 3.

PS: It can only be 3 stones at a time, no more no less. And to dupe other items such as materials, consumables and what not you need to have a stack of 128. and do the same process as the stones.

I'm having issues getting this to work with the stackable items. Could you reword or explain that part differently? I'm able to do the regular items just fine.
