Here is a way I have found to duplicate items.
1. Find and open your torchlight save game folder. Mine is in C:\Documents and Settings\[user]\My Documents\My Games\Runic Games\Torchlight 2\save
2. Open the folder inside your save folder (this contains your save info)
3. Open torchlight then take the item(s) you want to duplicate and put them in your shared stash.
4. Quit to the main menu and alt+tab out of the game to go to windows.
5. Copy the sharedstash.bin file and paste it in a new folder (I put mine on the desktop)
6. Go back into the game and load your game.
7. Once you are in the game move the item(s) you want to dupe out of the shared stash.
8. Quit to main menu and alt+tab back to windows.
9. Move the shared stash folder you copied before into the save folder and replace the 1 that is in there already.
10. Go back to the game and look at your stash. The item(s) will be in there and in your inventory.
Patched can u find a new way?:/
