Crimtane ore is a ore rarely found in the ground and is dropped off of the Brain of Cthulhu. The ore is essential to move on as the pickaxe belonging to this set is the only one capable of mining Hellstone.
Can be smelted into Crimtane Bars at any type of forge.
Added in the Hardmode update
- They are also dropped by the Eye of Cthulhu if the present biome is Crimson.
