Corruption

Function:

 * Corruption is the blight of Terraria spreading swiftly through it's soil and creatures. This dark energy can be used to corrupt metals, ancient artifacts and craft dangerous new magic items. Corruption is at times harder to collect than Purity; as a result, the items crafted with it are more powerful but harder to craft.

Collection:

 * Corruption was drawn into Terraria by dark powerful forces sometimes in small amounts and at other times in vast monstrous creatures. Corruption can be gathered in two simple ways: the first and easiest is to destroy a creature so corrupt that it forms into a raw material. The second method is to twist human souls through dark rituals performed at an Arcane Anvil.
