Way to split items in a stack in Torchlight 2

Disabling Steam Cloud Synchronization

It is unfortunate that you have to play two different characters on those computers, however if you are happy with this to be the solution, all you need to do is the following:

1. Right click on Torchlight II in your games list and select Properties

2. On the Updates tab, you will find a setting for disabling Steam Cloud (The Steam synchronization service)

It is your choice whether you want to disable Steam Cloud on both (Just follow those steps on the other computer). If you leave it enabled on one computer, you will have that game data safely backed up on Steam's Servers.

Resolving the Conflicts Later

First back up your game data

1. Navigate to %USERPROFILE%\Documents\My Games\Runic Games\Torchlight 2
2. Copy the saves folder to somewhere else and keep until certain that the game works.

If Steam Cloud conflicts when you re-enable it, tell steam to not copy either files:

Navigate to %USERPROFILE%\Documents\My Games\Runic Games\Torchlight 2\save in Windows Explorer and open the folder which is made up on random numbers (#################).

Add your other character file in there and then tell Steam Cloud to force your local files onto Steam Cloud.

Disclaimer: I have not tried this and have posted this answer entirely based on my theoretical understanding of this game. I cannot verify that this method will work. You should back up your game data first in case anything goes wrong or something breaks.

The sharedstash.bin file cannot be merged with another (to my knowledge), so that will not be able to be copied over. The character stash is saved in the character file, so that will remain intact.

Restoring Game Data if Something Goes Wrong

1. Navigate to where you backed up your saves folder.

2. Delete the saves folder in %USERPROFILE%\Documents\My Games\Runic Games\Torchlight 2 and then paste in your backup copy.

You can then either try again, try a different method or just choose to keep one set of game data.

The Transmuter will take one unsocketed item (even magic or enchanted) + 2 gems of equal or greater level (to the unsocketed item) to consume the gems and place a socket on the item.

As Rilgon Arcsinh pointed out, there is a small chance for an enchanter to add a socket to an item when asked to enchant it. Of course, this will use up one of the limited number of enchants for the item. There is also a named enchanter, Jurik the Socketer, who is guaranteed to add sockets when asked to enchant an item, up to a maximum of two sockets.
