Appraiser's Eye
This golden sphere is the size of an eyeball with a bejeweled iris. Its weight is negligible. The sphere has 3 charges and regains 1d3 expended charges daily at dawn. Even if you aren't attuned to the sphere, you can use it and its charges for the following properties.
While holding the eye, you can use an action to expend 1 of its charges to cast the identify spell from it. Alternatively, you can use the eye as the material component required for the legend lore spell. When you do, there is only a cumulative 10 percent chance that the sphere is consumed by the spell.
While you're attuned to the sphere, it also functions like a normal eye while it's in your socket, and you have advantage on Intelligence checks you make to determine an item's value, as well as on Wisdom (Perception) checks that rely on sight. In addition, if you cast legend lore and use the sphere as the material component for the spell while you're attuned to it, the 10 percent chance that the sphere is consumed by the spell isn't cumulative, and in the event that the sphere is consumed by the spell, it loses this property and can no longer be used as a component for the spell, but isn't destroyed.
You could tell who the curators were. Their single golden, jeweled eye could seemingly peer through anything to uncover its worth. Some would say they were blind to honest value — to emotion — while others would argue that they were the few who only saw things for what they were truly worth. The curators knew, though, that they were simply blinded by greed. Lured to temptation by the guilds of Antronec and the promise of wealth, they'd rip out their own eye only to be made poorer humans, plagued by gold and gemstone. They'd lost what had made them special. Valuable as people. Now they were only worth the gold they carried, and they were painfully aware that they could be replaced by anyone as gullible as they once were.
