"Making the world evil"
The Corruption is an evil biome with a dark purple wasteland, death, and decay theme, in contrast to the red gore theme of its counterpart, The Crimson. Every world will contain one of the two, generated randomly (each with a 50% chance of occurring) or chosen by the player upon world creation. Both contain similar hazards and feature their own unique enemies, items, and blocks. The tools, weapons, and armor obtained via Corruption materials are generally faster, but slightly less powerful than those obtained via Crimson materials. Corruption enemies tend to have slightly lower stats, such as health, defense, and damage.
The Corruption contains multiple chasms, underground extensions of the biome. Chasms lead downwards in a straight line, some crossing a horizontal connector, ending with a Shadow Orb. Demon Altars generally line the chasm's passages, appearing inside and around it. Chasms consist of Ebonstone, which can be blown up by explosives, purified by using Purification Powder which you can buy from the Dryad NPC, or mined with a Nightmare/Deathbringer Pickaxe or higher.
The Corruption spreads, meaning it slowly converts adjacent tiles to their Corruption variants. See below for details. Chasms, Demon Altars, and Shadow Orbs will only appear upon world generation, and will not spawn in a Corruption area that has formed through spreading. If enough Corruption manages to take over a new area, then that area will eventually adopt the Corruption's theme music, background, and water color. For an area to be considered a Corruption biome, at least 200 / 300 tiles of Corrupt grass or Corruption blocks must be present.

Spread[edit | edit source]
The Corruption spreads itself, similar to the Crimson and The Hallow. This means that it slowly converts certain susceptible tiles that are in the vicinity of existing Corrupt blocks. While its spreading capabilities are very limited during pre-Hardmode, it spreads much faster and more aggressively after defeating the Wall of Flesh. Defeating Plantera for the first time reduces the speed of the Corruption's spread by 1/2 (50%).
Corrupted Desert[edit | edit source]
In Hardmode, Corruption spreads through Deserts, transforming them into Corrupted Deserts. A Corrupted Desert is fairly similar to a regular patch of Corruption: The theme music and enemies are the same, with the addition of Dark Mummies on the surface and Dark Lamias, Vile Ghouls and Desert Spirits in the underground with Bone Biters During a Sandstorm .
Notes[edit | edit source]
- Corruption can be created or spread artificially using Corrupt Seeds, Unholy Water, or the Clentaminator with Purple Solution, obtainable from the Steampunker during a Blood Moon in Corruption worlds (she sells Red Solution in a Crimson world instead).
- It is possible to create an artificial Crimson biome in a Corrupt world without the use of another world. To do so, one must buy Crimson Seeds in Hardmode from the Dryad while in a Graveyard.
- Artificially creating a new Corruption biome requires at least 200 Corruption blocks. Although Crimson might replace Corruption at world generation, it does not prevent Corruption from being artificially created in a Crimson world (and vice versa); nor does it prevent the alien biome's spread.
- Any enemy in the Corruption or Underground Corruption has a 0.04% (1/2500) chance to drop a Corruption Key / Corruption Key Mold
- The Archaeologist's set can only be completed in a world with Corruption. The Hat can be dropped by Doctor Bones, which can spawn in any world, but the Jacket and the Pants can only be crafted with Leather, which is crafted using Rotten Chunk, an item exclusive to the Corruption.
Tips[edit | edit source]
For elaborate strategies on surviving in the Corruption, including detailed gear recommendations, see Guide:Surviving in the Corruption.
- Early on, determining whether a world contains Corruption is possible in the following ways:
|The tree in world selection (on the right: during Hardmode)|
- During world generation, one half of the progress bar will be green, and the other half purple (red for Crimson worlds). Additionally, the bar on the inside will be lime green (yellow for Crimson worlds), representing Cursed Flames (Ichor in Crimson worlds). The step in the world generation process in which the Corruption is created is called "Making the world evil" ("Making the world bloody" for Crimson worlds). Also, a tree at the side of the world name in the world selection has one green/normal side and one purple side (red for Crimson worlds).
- Due to the vertical, straight shape of the Corruption's chasms, fall damage is an omnipresent danger, should the player have not yet obtained anything that reduces or negates fall damage, such as Lucky Horseshoe (or its upgrades), Featherfall Potion, Umbrella (only works when held), or the Bunny or Bee Mount.
- Climbing out of a chasms requires certain gear as well: any hook, Climbing Claws/Shoe Spikes (or their upgrades), any Rope (though note that enemies can easily knock the player off), Slime Mount, or items enhancing the player's jump ability (see Jump Height Comparison).
- Hooks are viable for both negating fall damage and getting out of chasms.
- It is recommended to cover all chasms with platforms to reduce the likelihood of accidentally falling into one and suffering fall damage. Placing rows of platforms inside the vertical chasms can be helpful, too.
- In Hardmode, it may be worth buying Crimson seeds from The Dryad and create an artificial Crimson biome.
Trivia[edit | edit source]
- Many Corruption enemies have rotten bodies, sometimes with green pus dripping out of them, as seen with the Eater of Souls and Corruptor. This contrasts with the Crimson enemies' abnormal cancerous-like growths.
- The lengthy chasms of the Corruption might be interpreted as worm tunnels, evidenced by its worm-like boss. Similarly the chasms in the Crimson could be neurons (cells found in the brain), relating to its associated boss,the Brain of Cthulhu.
- The horror media franchise Dead Space features an organism also called the Corruption, which spreads and terraforms affected areas, serving as habitats for the franchise's signature zombie-like creatures, the Necromorphs. Terraria's Corruption may have been based on this.
- The game Anti-Idle features an area called the Corruption, based heavily on the Terraria biome.
- The Corruption and its Shadow Orbs seem to be based heavily on "The Colour Out of Space", a science fiction/horror short story by American author H. P. Lovecraft, written in March 1927. In the story, a meteorite crashed near a small fictional town. The meteorite twisted the land, drove people insane, drained the life forces of anything around it, and deformed animals into grotesque abominations.
- This may have something to do with why meteorites begin falling after a Shadow Orb is smashed.
- During a Blood Moon, three critters turn Corrupt (the Corrupt Bunny, Corrupt Goldfish and Corrupt Penguin), a reference to the Corruption. They can also manually be turned Corrupt with Vile Powder.
- – According to the official game lore, the Corruption is a cancer caused by the sins of those living in the worlds of Terraria, and is strenghtened by the vile actions and thoughts present in all living beings. Its purpose is to restore balance to life and then destroy it, leaving the world a lifeless abyss.
- Usually there is only Corruption or Crimson generated in a world, but if you use the seed "516808" when you create a world, you will get a world that is both Corruption and Crimson.
- With the revamped terrain generation of Desktop version1.4, this is no longer the case, but there is now a seed "05162020" which will give a world with both Corruption and Crimson, both sets of ores, and other oddities. In addition to not actually being the same as any other 05162020 world.
