Aerialite Ore

"The ground is glittering with cyan light."

Aerialite Ore is a Pre-Hardmode ore which generates anywhere in the Underground and Cavern layers upon defeating The Hive Mind or The Perforators. It is used to craft Aerialite Bars at a Furnace. It requires at least a Nightmare Pickaxe or a Deathbringer Pickaxe to mine. It is also dropped by Aero Slimes.
