Have you ever played an MMO and been forced to create a mule character to transfer items between your characters? Maybe you’ve had to pay to mail items to alternate characters? No matter how developers try to prevent this “out of character” practice from happening there is always a workaround.
Dimensional chests are a shared storage space between all of your characters. You can also use it for personal storage as well but know that you no longer need to create mule characters to share equipment across all of the characters on your account.
There is no cost to use a dimensional storage chest and they are provided to keep you doing what you want to do, playing the game.
Dimensional chests are most often located in civilized areas such as shops or encampments so keep your eye out for them there.
