The spread of the Corruption, Crimson, and Hallow is a constant concern for any Terraria player venturing into Hardmode. While these biomes have a slow, creeping presence before defeating the Wall of Flesh, their expansion explodes into a rapid and potentially devastating force afterward. But what happens after you conquer Plantera, the jungle’s guardian? The answer is simple: defeating Plantera reduces the spread speed of Corruption and Crimson by 50%.
This decrease significantly impacts your world’s survival, giving you a much-needed breather and a better chance to contain the encroaching evil. Understanding the mechanics behind this slowed spread is crucial for effectively managing your world’s biome balance and preserving your precious builds. Let’s delve into the specifics and answer some frequently asked questions about biome spread in Terraria.
Understanding the Post-Plantera Spread
After defeating Plantera, the game essentially halves the rate at which the Corruption and Crimson convert blocks. This doesn’t mean they stop spreading entirely, but it provides a more manageable pace. Before Plantera, the evil biomes spread aggressively to almost any natural block. With the reduction after defeating Plantera, the pressure of constant biome control is significantly reduced.
FAQs: Taming the Corruption
Here are some frequently asked questions to help you further understand and manage biome spread after defeating Plantera and in general.
Can I completely eradicate the Corruption/Crimson/Hallow?
Yes, it is possible to completely purify your world! The primary tool for this task is the Clentaminator, purchased from the Steampunker NPC. This device sprays a solution that converts blocks within a certain radius (approximately 60 tiles). Eradicating the Corruption, Crimson, or Hallow requires patience, thoroughness, and a steady supply of the appropriate solution (Green Solution for purification, Purple or Red for spreading the evil biomes, and Blue for spreading the Hallow). It is recommended to dig tunnels to easily clentaminate the underground areas.
How wide should my quarantine trenches be?
A minimum of 3-tile wide trench is essential for creating a quarantine zone. This ensures that thorny bushes and other spreading elements from the Corruption or Crimson cannot bridge the gap. Lining the trench with non-corruptible materials like wood, clay, or bricks further enhances its effectiveness.
What materials are immune to Corruption/Crimson/Hallow?
Several materials resist conversion, making them ideal for building protective barriers. These include:
- Clay Bricks
- Wood
- Silt
- Ash
- Gray Brick
- Any man-made brick
How far can the Corruption/Crimson spread?
Corrupt and Crimson variants can grow 6 tiles in all directions, and spread their biome up to three blocks away like any other source. Their spread can be contained with physical neutral barriers, like Clay or Wood. Remember, thorns and vines from Corruptors and Crimson creepers can extend over gaps, so be mindful of these.
Does the Hallow spread faster than the Corruption/Crimson?
All three grass variants spread in an equal manner. However, Hallowed grass has the unique ability to overtake Crimson grass. Therefore, there is none that is “faster” or “stronger”.
Do Demon/Crimson Altars contribute to biome spread?
Destroying Demon Altars or Crimson Altars has a 66.67% chance of converting a single random Stone Block in the Cavern layer to Ebonstone/Crimstone or Pearlstone, which facilitates the spread of the Underground Hallow or Corruption/Crimson. However, altars themselves do not directly contribute to the overall Corruption/Crimson percentage.
Can the Corruption/Crimson spread through ice or snow?
In Hardmode, the Corruption, Crimson, and Hallow can spread through ice, generating Purple, Red, and Pink Ice Blocks respectively. However, they cannot spread through snow blocks.
Do Sunflowers really help prevent spread?
Yes, Sunflowers offer limited protection against the Corruption, Crimson, and Hallow. The two tiles directly underneath them cannot be converted. Additionally, each Sunflower decreases an area’s total Corruption rating by 5 tiles. However, their influence is relatively small, making them best suited for small-scale protection or early-game efforts.
Can NPCs live in the Hallow?
Yes, unlike the Corruption and Crimson, NPCs can live in the Hallow without suffering any penalties. In fact, many players intentionally create Hallowed biomes around their bases to provide a safe and pleasant environment for their NPCs.
Can I have both the Corruption and Crimson in my world?
While worlds typically generate with either the Corruption or Crimson, it is possible to introduce the opposite biome. You can acquire seeds or solutions from other players or create a new world and transfer the necessary items. Then, use the purchased solutions from the steampunker to spread the opposing biomes to create the ultimate evil in one world.
What does the Dryad say when the world is pure?
When your world is completely free of the Corruption, Crimson, and Hallow, the Dryad will say: “[Name of World] is completely pure. You have done an amazing job!” or “The world is in balance”.
Can the Mushroom biome be corrupted?
No, the Mushroom biome is immune to the spread of the Corruption, Crimson, and Hallow. This makes it a safe haven and a suitable location for housing the Truffle NPC.
Can I fight the Brain of Cthulhu in a Corruption world?
Yes, it is possible to fight the Brain of Cthulhu in a world that generated with the Corruption. Simply create a Crimson biome artificially and use a Bloody Spine within it to summon the boss.
Is the Crimson really better than the Corruption?
The choice between the Crimson and the Corruption is largely a matter of personal preference. Each biome offers unique items and benefits. Crimson armor provides health regeneration, while Corruption armor grants a melee speed boost. Ultimately, the “better” biome depends on your playstyle and character build.
What is the Steampunker’s role in controlling biome spread?
The Steampunker is a vital NPC for managing biome spread. She sells the Clentaminator and various solutions, including Green Solution for purification, and Red or Purple solutions for spreading the evil biomes. Access to her wares is essential for effectively controlling and manipulating the biome composition of your world.
Conclusion: Mastering Biome Control
While the Corruption and Crimson can be daunting forces in Terraria, understanding their mechanics and utilizing the tools at your disposal allows you to effectively manage their spread. Defeating Plantera provides a significant advantage by slowing down the spread, giving you more time to build defenses and purify your world. By leveraging the knowledge gained from this guide, you can create a balanced and thriving world, free from the encroaching darkness.
