The Corruption

The Corruption is an ominous environment. Purple corruption spreads over nearby dirt blocks and trees, and Thorny Bushes sprout, making it a difficult land to traverse. Deathweeds can be found here. Purification Powder can be used on corrupted dirt to turn it into "healthy" dirt, and Sunflowers can be placed to stop the corruption from spreading further.

Many chasms dot the landscape in the Corruption. It is recommended that you don't explore these until you have a Grappling Hook or some other form of vertical transportation, as chasms can be hundreds of feet deep. Chasms are covered in Ebonstone Blocks which can only be mined using a Nightmare Pickaxe or better, or by using Dynamite. Alternatively, Purification Powder can be used to turn the Ebonstone into normal Stone Blocks which can be mined with any pickaxe.

Caves can often be found surrounding the chasms. In these caves, Pots, Chests, Life Crystals and Demon Altars are common.

Corruption vs. "The Corruption"

 * Corruption is a purple grass-like substance that infects dirt blocks and spreads quickly to any connected dirt blocks, similar to ordinary grass.
 * "The Corruption" is a term used to describe the biome that takes effect when a multitude of Corruption exists in an area of the World; theme music is changed in such areas (to The Corruption's theme), Trees turn purple, the sky darkens, and Corruption enemies like the Eater of Souls spawn.

A small amount of Corruption can exist in other biomes, the same way Jungle Grass can exist in biomes that are not yet actual Jungle biomes, and Meteorite blocks can exist in biomes that are not Meteorite biomes. A multitude of any of these in an area will cause the respective biome to exist though, with altered theme music and spawned enemies appropriate to those environments.

History

 * 1.0.5 : Corruption areas now have cave systems connecting many of the chasms. Small to medium deposits of Demonite Ore can now be found when exploring the chasms.
 * 1.0.4 : Number of chasms generated in the world is decreased, but each chasm now has 100% chance to spawn a Shadow Orb.
