When you have upgraded to certain level, you'll certainly need some more advanced equipments. However, it is a waste of you discard all embedded gems. Therefore, you can use the Remove Gem function to remove them.
Choose "Remove" in Armory in any main city to enter the interface. Drag the item you need to remove gems into corresponding place to start. A light blue color will appear if gems can be removed.
Gold or gift coupons are needed for each remove. You can choose to remove one gem if more than one are embedded. Removed gem will be placed into the bag and the slot will be free. If the equipment is unbound, the removed gem will be unbound, and vise versa.Back
