Here is another tip.
Ok, this tells you how to take a cash shop item and put in a different server to another character. Example, If you play in Bera and also have a character in Scania. you can transfer the item from the guy in bera, to the guy in scania. First, wait until any cash shop item expires from your guy in bera, then unequip any cash shop item that you want to transfer, so it shows it in your inventory. (but don't enter the cash shop in bera or it wont work!) Then Go to the character in scania and enter the cash shop, it will tell you the item that in Bera expired, and all your cash shop items that weren't equipped with the guy in Bera will appear in the Cash shop in Scania! this trick also works with pets.
