As soon as you enter hardmode Terraria, World Corruption, Crimson, and the new Hallow biomes all begin to expand outward. Left alone, these biomes will eventually engulf your entire world, destroy NPC villages, and generally make life difficult.
Thankfully, there are various ways to remove Corruption and Crimson from the world of Hard Mode. In this guide, we’ll cover everything you can do to prepare for the spread of Hard Mode’s evil biomes, and what you can do to get rid of it once and for all in Endgame.
Updated April 9, 2023: Jacqueline Zalace Terraria’s rot and crimson are a bit of a pain to deal with. For this reason, we have added information to help you deal with these evil biomes. Additionally, we’ve added some tips for dealing with Hallow.
What are Corruption and Crimson?
Corruption and Crimson are the main evil biomes in your world.Each world spawns in either Corruption or Crimson biomes, but there are one or two rare seeds that spawn both. Before starting generation, you can choose to start with either a Corruption or Crimson world.
Your biome determines the bosses you face. Like Crimson’s Cthulhu Brains or Corrupt Eater of WorldsThis also determines the types of armor and weapons you can craft before entering hardmode.
Overall, these two modes are of equal difficulty, so it’s up to you which one you face in your world.
How Corruption and Crimson Spreading Work
Both biomes slowly expand even before hardmode. They convert nearby blocks to the same biome at a very slow rate. Before Hardmode, it only spreads on grass and bushes. The converted area will have the same background music, the same enemies, and the same plants.
Certain biomes, like desert and snow biomes, have a unique version of the biome when converted to rot or crimson.For example, in the Crimson Desert, enemies such as Blood Mummies appear on the surface and Dark Lamia below. Snow biomes have no unique enemies, but ice turns into red ice.
every altar you destroy Increases the spread speed of evil biomes. take care.
Decayed biomes spread particularly quickly through soft blocks, snow, mud and so on. This means that deserts, snow biomes, and jungles are highly susceptible to rapid spread of corrupted biomes. As a result, jungle biomes can quickly be completely overrun if they are near evil biomes.
hard mode spread
Things get even more complicated in hard mode. Not only does the spread rate increase significantly, Evil biomes extend to stone and vinesi.e. Corruption or Crimson is spread undergroundnot only on the surface.
Rot and crimson can spread through sand, dirt, grass, stone, and almost all default natural blocks.
As soon as you defeat the Wall of Flesh and enter Hardmode, your spread speed increases. However, defeating Plantera will reduce this rate.
This will prevent the biome from spreading too quickly if you haven’t prepared the world.
What is Hallow?
Hallow is a third spawn biome that only exists once you reach Hardmode. After defeating the Wall of Flesh, some of the evil biomes in the world become Hallow.
Like Crimson and Corruption, Hallow will spread. Overall, it spreads by a similar mechanism. It’s a “cute” biome, but the mobs are still dangerous. Interestingly, two evil biomes cannot spread through his Hallow and vice versa. When these biomes meet, diffusion stops.
Unlike Crimson and Corruption, Hallows do not spread through mud blocks or Glowing Mushroom biomes.
Dig a hole to stop biome spread in pre-hard mode
This method is very time consuming, but it’s also the most effective way to prevent Crimson and Corruption from finally ruining your world. very big hole.
The system is simple. Dig a tunnel that completely covers the Corruption or Crimson biomes before defeating the Wall of Flesh.. Alternatively, you can dig a tunnel around the base If you want to keep everything in one place.
I need to dig a tunnel around At least 3 blocks widealthough we recommend Just in case, let’s make it 6.
Imagine drawing a circle around a Corruption or Crimson biome. This trench prevents affected blocks from spreading beyond it.
Remember, Vines grow in tunnels and spread rot when entering hardmodeThese grow from under grass blocks.
It will take longer, but Wrap the tunnel with cheap blocks like stone, Prevents vines from growing along walls of soil. It’s very frustrating when the vines are constantly ruined and labor is expended to protect the tunnels.
Tips for quick digging
If your world is still pre-hardmode, you won’t have access to some of the best mining equipment in the game.No super pickaxes, drills, or megabuffs for mining. There are a few things you can use to make this process as smooth and quick as possible. These mining methods can be found below.

How to rid your world of rot and crimson
If you haven’t dug tunnels to prepare for Hard Mode, you may find your world is rapidly overrun with evil biomes.
Talk to Dryad and it will tell you How many evil biomes are present in your world. This is useful when there are a few remaining bits that need to be cleared.
Completely remove rot and crimson
To completely rid your world of rot and crimson, you’ll need:
- Steampunker NPC
- This NPC will appear when you defeat one or more Mecha Bosses that appear in Hard Mode.
- Cleantanimeter
- green solution
- pile of coins
Clentanimator is a useful tool sold by Steampunker on hard modealthough she should live in Home of the jungle biome. However, it is one of the most expensive items in the game.This tool can be used for both Create and destroy biomes.
Green Solution is the ammunition you put inside the Clentanimator.when fired Replaces evil biomes Uses the tile that was originally underneath (called “purity”). But be careful. Turn your jungle into a glowing mushroom biome.
You can also remove Hallow using Clentanimator. This is done in the Green Solution, but you can purchase the Blue Solution to expand your colorful biomes even further.
The best way to get rid of it all (and ultimately satisfy the dryads) is dig a series of vertical tunnels Fires Clentanimator left and right. This way you should be able to cover a good portion of the affected area.
Can the whole world become evil?
What happens when the whole world becomes the crimson of corruption? Luckily, this doesn’t happen naturally.
Both of these evil biomes cannot spread through Hallow. So as long as Hallow exists, there will be at least two biomes in the world. However, using Clentanimator he can remove Hallow. Doing this without removing the evil biomes can lead to the world being overrun.
Even if the world becomes completely evil, you can get rid of it with Clentanimato. This will take a long time, but all hope is not lost.
