Just like on regular worlds where we have to find parts for a purifier. Why not a machine for rare ores/items? It wouldn't find it for you, but it would tell you how many you have in your world (Natural ones) the only ones it would show numbers for are Crystals, Onyx, Diamonds, Beryllium, and specific mushrooms. And yes I said ores that are in different biomes. But this machine would be available in different biomes. So what do you think about this idea? Good? Bad? PLEASE, constructive critism.
