Transfer Bonus

As you gear gets deprecated through leveling and better set pieces are being obtained, the best thing to do is tranfering bonuses from one piece to another.
You can do it through transfer bonus system, but with a few limitations:

You can only transfer bonuses to an item that is not holding any upgrade or maker.

• You can not transfer a "brutal 2.5x maker" to an item that already has a "brutal 1.75x maker"
• You can not transfer a "brutal 2.5x maker" to an item that has a "+1" upgrade
• You can not transfer a "+1" upgrade to an item that already has a "brutal 2.5x maker" attached to it.
• You can not transfer a "+4" upgrade to an item that has a "+1" upgrade

You can only transfer bonuses of the same slot class.

• It means you can't transfer bonuses between an "armor" and a "backpack", only from "armor to armor".
  
• The same happens with weapons, you can't transfer between a "sword" and a "bow".

For items with tier, you will need a Class 4 Transfer Token to transfer the tier to another item.

To transfer, it requires you to have at least 1 crystal coin on your inventory, although it may not be the final transfer price.
