Because of their extreme rarity, a Mirror of Kalandra is only used to duplicate the absolute best rare items available - the mirror will be consumed on use! Players that own these top rare items will provide "Mirror service" to players looking to use their Mirrors. Usually, the Mirror is given to Mirror service provider, the item is duplicated, and then the duplicate item is then traded back. This process typically includes a "Mirror fee", to be paid to the Mirror service provider, as well as some exchange of collateral, so that the original Mirror owner is insured against having their Mirror stolen.
