Storm Diver's Additions Mod/Arid Ore

Arid Ore is a crafting material that generates in the Underground Desert biome once a Sand Elemental or a has been defeated, it can also drop in small quantities from any enemy in the biome once the same criteria is met. It can also be obtained from Wooden Crates and requires a pickaxe with at least 100% pickaxe power to mine.

Trivia

 * The generation of the ore can be disabled in the config menu, but it will still drop from enemies and crates.
