Invisiblium Ore

Invisiblium Ore is a Hard Mode ore that spawns when the Wall of Flesh is defeated. It looks exactly like empty air. It can be mined with a Molten Pickaxe or better. When mined, the slot in your inventory the ore goes into will look exactly like an empty slot. The quantity will also not be shown, but will be shown when you hover over the slot.

Placed Invisiblium will also look like empty air. A Luminescence Potion will make placed Invisiblium Ore/Bars and any Invisiblium item in your inventory glow blue. When this is in effect, it will resemble Mythril. This potion will not reveal natural Invisiblium however. Spelunking Potions will not work either, making Invisiblium tough to find.

Invisiblium Ore is about as rare as Adamantite after 2 altars (technically 6) have been smashed.
