Mule

A character created only or mostly for the purpose of extending your inventory space for your account to store items and material is often referred to as a "mule".

To maximize storage space a good Mule will be equipped with a Belt Pouch and two Bags with Runes of Holding applied. PvP charachters are good for being "mules" because they don't take much time to make.

Note: You can swap items between the different characters on your account by using the Xunlai Agent storage space.
