Abuse and Crimson are the main evil biomes of your earth. Each world will spawn with either a Corruption or Crimson biome, though there are one or two rare seeds that volition spawn both. You tin can choose whether you commencement with a Corruption or Crimson globe before you lot outset generating it.

The biome will make up one's mind which bosses you face, like the Brain of Cthulhu for the Crimson and the Eater of Worlds for Abuse. This volition likewise dictate what sort of armor and weapons you can create before y'all enter into Hardmode.

Overall, these 2 modes are the same difficulty, so it's upward to you which one you want to face in your world.

Both biomes volition slowly spread, even earlier Hardmode. They catechumen nearby blocks to the same biome at a very slow rate. Corruption and Cherry-red can spread through sand, mud, grass, stone, pretty much every default natural cake in Hardmode, only in pre-Hardmode, they simply spread through grass and bushes. Converted areas will have the aforementioned background music, spawn the same enemies, and abound the same plants.

Specific biomes, like the Desert or Snow biome, will have unique versions of the biome when converted into either Corruption or Scarlet. For example, the Crimson Desert volition spawn enemies like the Claret Mummies on the surface, and Dark Lamias cloak-and-dagger. The Snowfall Biome has no unique enemies, only the Water ice will catechumen to Red Ice.

Below, yous can bank check out some helpful data most evil biomes.

  • Pre-Hardmode the biomes can only spread through grass blocks and the Crimson thorny bushes. This means you lot can merely build a stone wall on the edge of your biome if you want to stop information technology from spreading.
  • Things go more complicated in Hardmode. Not only does the rate of spread increment significantly, but the evil biomes will too spread through stone and vines, which means Abuse or Cherry-red will spread underground, non just on the surface.
  • The rate of spreading is sped upwardly as soon as you lot defeat the Wall of Flesh and enter Hardmode. Yet, this rate is then decreased once you defeat Plantera. This should cease the biomes from spreading super rapidly if yous haven't prepared your world. You tin blitz this boss, if yous're capable, and reduce the take a chance of your world becoming overwhelmed.
  • Every Altar you smash (which spawns more than Hardmode ores) will besides increase the speed of Evil biome spreading. Be careful.

Excavation Holes To Cease Corruption And Carmine Spreading

This method is completely time-consuming but is also probably the about effective fashion to prevent Red and Corruption from eventually ruining your globe. It involves digging holes. Very big holes.

  • The system is elementary: dig tunnels that entirely encase your Corruption or Crimson biomes before you defeat the Wall of Mankind.
  • Alternatively, yous can dig tunnels that surround your base. Because 1.4 encourages multiple villages full of NPCs, this is a bit more than difficult than information technology used to be, but might save you time.

You need to dig a surrounding tunnel that is at to the lowest degree 3 blocks wide, although we recommend going for 6, just in case. Imagine you're drawing a circle around your Corruption or Crimson biome. This trench will forbid the affected blocks from spreading past information technology.

Remember, vines can abound in tunnels and will spread Corruption. These will abound from underneath the grass blocks. Even though information technology's fifty-fifty more time-consuming, you should encase the tunnels in a inexpensive block, like rock, to forestall vines from growing forth the clay walls. It's extremely frustrating if the vines ruin all the time and effort put into securing your tunnels.

If yous don't dig tunnels in preparation for Hardmode, you lot might realize that your world is quickly becoming overrun with Evil biomes.

  • These corrupted biomes spread particularly chop-chop through soft blocks, similar snow, and mud.
  • Deserts, Snow Biomes, and the Jungle are very susceptible to the quick spread of the corrupted biomes.

As a result, the Jungle biome tin can very quickly go completely overrun, removing the biome from your earth.

If you speak with the Damsel, they will tell you how nowadays the evil biome is in your world. This is helpful if you just have a small flake left that needs to be cleared.

Completely Removing Corruption And Crimson

using the clentanimator and green solution to remove corruption

To completely remove Corruption and Crimson from your world, you will need the following:

  • The Steampunker NPC
    • This NPC will only appear in one case yous defeat at least one mechanical boss, which appear in Hardmode.
  • The Clentanimator
  • Light-green Solution
  • A stack of coins

The Clentanimator is a useful tool sold past the Steampunker in Hardmode, though she has to exist living in a Jungle biome home. Come prepared, though, information technology's one of the well-nigh expensive items in the game. This tool can be used to both create and destroy biomes.

Green Solution is the ammo you put inside the Clentanimator. When fired information technology replaces the Evil biome with whatever tile was underneath originally (referred to as "Purity.") Careful, though, this solution volition also transform your Jungle into a Glowing Mushroom biome.

The Clentanimator has a range of 60 tiles and is extremely satisfying to use.

Ane problem is that information technology's quite hard to get rid of absolutely all of the Evil biomes. The best way to attempt and go rid of all of information technology (and finally satisfy the Damsel) is to dig a series of vertical tunnels and burn the Clentanimator side to side all the way downwardly. This way y'all should be able to embrace a skillful portion of the afflicted expanse.
