Crimstone Block

Crimstone Block is the stone found in the Crimson and requires a Deathbringer Pickaxe or explosives to mine. They are spread over the biome, and in hardmode, can affect nearby stone and grass, causing it to become corrupted with the crimson. You can also use these blocks to spread or make an artifical Crimson. A house cannot be built using this material, nor can it be built near this material. Exact number of crimstone in the area required to invalidate housing is currently unknown. Unlike its counterpart Ebonstone which is found in the Corruption, it can't be used to make bricks. Individual blocks of crimstone can also be occasionally found in the Underground.
