Radioactive Ore is a rare resource obtained primarily by mining in the Skull Cavern or from treasure chests and monsters. It emits a green glow and can be smelted into Radioactive Bars, which are used in crafting or sold for a high price. Handling it does not cause harm, but it serves as a valuable material for late-game items and upgrades, including the crafting of the highly effective Radioactive Sprinkler.
