Can You Completely Get Rid of Corruption in Terraria?

The short answer is: yes, you absolutely can completely get rid of Corruption (or Crimson) in Terraria, but it requires time, effort, and the right tools. This isn’t a task you can accomplish early in the game. Instead, it’s a long-term project that becomes feasible once you’ve progressed into Hardmode. Let’s delve into the process and explore the nuances of eradicating these pervasive biomes.

The Challenge of Corruption and Crimson

Before tackling the solution, it’s important to understand the problem. Both Corruption and Crimson are evil biomes that can spread rapidly once you enter Hardmode. They can overtake your world, converting various blocks and altering the landscape. This spread can be frustrating, turning your beautiful builds into a chaotic, monster-filled wasteland. While these biomes have their uses, such as spawning unique enemies and providing specific resources, many players prefer a world free of their influence.

Why Eradicate the Evil Biomes?

Several reasons might motivate a player to eliminate Corruption or Crimson:

• Aesthetic Preference: Some players simply prefer the look of a pure world and dislike the visual changes brought on by these biomes.
• Base Safety: In the early stages of Hardmode, the enemies spawned in Corruption and Crimson biomes can be dangerous and pose a threat to your base. Eliminating them ensures a safer home environment.
• NPC Happiness: Although NPCs can live in the Hallow, they generally don’t enjoy living in the Corruption or Crimson biomes, and their unhappiness will affect the prices they offer and the items they sell.
• Personal Challenge: For some players, the act of purifying their world is a challenging and satisfying endgame project.

The Tools for Purification

To completely remove Corruption or Crimson, you’ll need the following:

• The Steampunker NPC: This NPC arrives after you defeat at least one mechanical boss in Hardmode. She’s crucial for accessing the next two tools.
• The Clentaminator: This tool, purchased from the Steampunker, is your primary weapon against evil biomes. It fires a spray that converts blocks.
• Green Solution: This special ammo, also purchased from the Steampunker, is used with the Clentaminator to convert infected blocks back to their original, non-corrupt state.
• A Stack of Coins: You’ll need quite a bit of money to purchase the Clentaminator and a large supply of Green Solution, as the process can be resource-intensive.

The Process of Purification

1. Locate and Assess: Start by identifying the areas affected by Corruption or Crimson. Pay attention to underground chasms and areas close to the surface.
2. Create Tunnels: Dig tunnels through infected areas, especially beneath the surface, to allow easy access. The Celebration MK2 is an effective tool for quickly clearing out large areas to make pathways.
3. Spray the Solution: Use the Clentaminator with Green Solution, systematically spraying the infected blocks. Be thorough; if you miss even a few spots, the spread can resume. It’s important to note that you need to be close to the area you wish to convert for the Clentaminator to be effective.
4. Watch out for Vines and Thorns: Be aware that the Crimson and Corruption spread via vines that grow beneath the grass blocks and can convert the walls, so it is imperative to get rid of these vines.
5. Monitor Progress: Regularly check previously purified areas for any signs of regrowth. Sometimes the evil biomes spread through walls which may need some time to be dealt with. The Dryad can tell you the percentage of corruption on the map and tell you when it is completely pure.

Important Considerations

• Hardmode Spread: Be prepared for the increased spread rate of Corruption and Crimson after entering Hardmode. It’s best to have a strategy in place before engaging the Wall of Flesh.
• Hallow: The Hallow is an anti-corruption biome and can be used to contain the spread. While it can co-exist with Corruption and Crimson, it does not remove it. The Hallow can be spread through the use of Hallowed Seeds, Holy Water and with the Clentaminator using Blue Solution.
• Walls: It’s important to note that while blocks that are infected will spread corruption to other blocks, it is not necessary to replace the walls unless the spread is from vines.
• Preventative Measures: Prior to Hardmode, you can use Sunflowers to limit the spread and build trenches filled with uncorruptible materials like Clay, Bricks, Silt or Ash to act as barriers, though the sunflowers are only effective pre-Hard Mode, and the trenches may not be perfect, as the evil biomes can also spread through vines.
• Time Commitment: Purifying your entire world is a significant undertaking that can take many hours, even days. Be prepared for a long haul.
• Smashing Altars: Each time you smash an altar in Hardmode, it will cause a random stone block somewhere in your cavern layer to convert to ebonstone, crimstone or pearlstone, so it is vital to clear out these areas if you intend to purify your whole map.

Frequently Asked Questions (FAQs)

1. Can you stop Crimson from spreading in Terraria?

Yes, similar to the Corruption, Crimson spread can be stopped and reversed. Using blocks of lava can also prevent surface Crimson spread by burning the grass, but this isn’t confirmed in Corruption biomes. The Hallow can also contain the Crimson, but it’s not recommended for early Hardmode due to its dangerous enemies.

2. Should I get rid of the Corruption in Terraria?

It’s up to personal preference. If you dislike the biome’s enemies, aesthetics, and spreading capabilities, then it’s a good idea to remove it. It also is helpful for NPC happiness. However, Corruption does provide unique resources and enemies, such as the mimics, which can be useful to farm.

3. How do you purify a world in Terraria?

The most effective method is using the Clentaminator with Green Solution. Dig tunnels through infected areas and spray the solution to convert the corrupted blocks to their original state.

4. What does the Dryad say when you cleanse the world?

When your world is completely pure, the Dryad will say: “[Name of World] is completely pure. You have done an amazing job!” or, if there is some hallow: “The world is in balance.”

5. Do Sunflowers stop Corruption?

Yes, Sunflowers prevent the two blocks beneath them from becoming Corrupted, Crimsoned, or Hallowed. This can be helpful for minor containment in pre-hardmode, though they won’t have any effect in Hard Mode.

6. Does smashing altars spread corruption?

Yes, each time you destroy a Demon or Crimson Altar, a random Stone block in the Cavern layer is converted to the evil or Hallow variant, which helps the biome spread.

7. Is Corruption better than Crimson?

Neither is “better”. The Crimson offers slightly better loot but has tougher enemies, while the Corruption has easier enemies but weaker gear. It’s down to player preference.

8. What can the Hallow spread to?

The Hallow spreads to Pearlstone, Pearlsand, and dirt blocks, causing hallowed grass to grow, similar to how evil biomes spread.

9. Can Hallow spread via walls?

The Crimson and the Hallow both grow vines from beneath their respective grass blocks that can spread their biomes to blocks and walls in Hardmode.

10. Do you have to destroy walls to stop Corruption?

No. You do not need to destroy or replace the walls of an area to stop it from spreading, except for vines.

11. Can NPCs live in the Hallow?

Yes. NPCs can live in the Hallow without any issues, unlike Corruption or Crimson.

12. Can Gray Bricks be corrupted?

No. Gray Bricks are resistant to the spread of Corruption, Crimson, and Hallow.

13. What weapon stops Corruption in Terraria?

The Clentaminator is the primary tool for removing Corruption, Crimson, and the Hallow.

14. Is there a way to get both Corruption and Crimson?

Yes. It’s possible to have both in your world by spreading blocks from one biome into the other. For instance, you can place corrupt stones in a Crimson biome to create a Corrupted area and vice versa. You can also buy seeds from the Dryad in a graveyard.

15. Can Hallow overtake Corruption?

The Hallow is an anti-corruption biome and can counteract its spread. It will not directly destroy or convert an area of corruption, but it will slow or halt its spread, and both biomes can still spread over each other, just at a very slow rate.

Conclusion

Purifying your world in Terraria is a challenging but rewarding endeavor. It requires careful planning, resource management, and a good amount of patience. While it may seem daunting, with the right tools and approach, you can effectively eradicate Corruption and Crimson, creating a world that is both aesthetically pleasing and free from the influence of evil biomes. Remember, the journey is just as important as the destination. Good luck on your purifying adventure!
