Crimtane Ore

Crimtane Ore is a pre-hardmode ore that was added in the 1.2 update. It has a luminescent blood red color and can be easily spotted underground due to its glowing effect. It can be found underground; more specifically, in the Crimson Biome's Chasms.

Crimtane is extremely rare to find, so it is not recommended that the player go mining for it. Defeating the Brain of Cthulhu, which can be summoned repeatedly by breaking Demon Hearts or by crafting Bloody Spines, is the easiest way to farm this ore. Crimtane is also dropped by the Eye of Cthulhu in worlds which contain the Crimson biome instead of the Corruption.

Crimtane can be crafted into bars which are then used in the creation of Crimson Armor and its coinciding tool kit. Unlike Demonite Ore, its Corruption counterpart, Crimtane cannot be crafted into bricks.

Like Demonite Ore, the pickaxe power required to mine Crimtane changes with location. Below ground level a Gold Pickaxe or better is needed, while above ground level any pickaxe will do.
