Can You Purify Hallow in Terraria? A Comprehensive Guide
The short answer is yes, you can purify the Hallow in Terraria, but not in the way you might initially expect. Unlike the Corruption or Crimson biomes, which can be converted using Purification Powder, the Hallow requires a different approach. This article will delve into the intricacies of managing and removing the Hallow, providing you with a comprehensive understanding of this unique biome.
The Unique Nature of the Hallow
The Hallow is a Hardmode biome that appears after defeating the Wall of Flesh. It’s characterized by its vibrant, pastel colors and a more whimsical feel compared to the sinister Corruption and Crimson. While the Hallow is often considered “good” by the Dryad NPC, it’s not without its challenges. It can spread aggressively across your world, and you might eventually want to contain or even completely remove it.
Understanding the Limitations of Purification Powder
The most common tool for biome purification in early gameplay, Purification Powder, has absolutely no effect on Hallowed blocks or walls. This can be a source of frustration for new Hardmode players who are used to using it to manage the spread of evil biomes. Attempting to use Purification Powder on Hallowed ground will not yield any results.
Vile Powder: Your Early Solution to Hallow Removal
The key to reversing the Hallow’s spread, especially early in Hardmode, is using Vile Powder. Vile Powder, made from Vile Mushrooms found in the Corruption or purchased from the Dryad during a Blood Moon, has the unique ability to convert Hallowed blocks back to their original state. This includes converting Pearlstone to Ebonstone or regular Stone, and reverting Hallowed grass back to normal grass.
The Clentaminator: The Ultimate Biome Management Tool
While Vile Powder is a viable early solution, the Clentaminator is the ultimate tool for managing the spread of the Hallow and other biomes. This item, purchased from the Steampunker NPC, uses different “Solutions” to quickly convert large areas.
- Green Solution is specifically used to remove Hallow, Corruption and Crimson, returning the blocks to their default state.
- Blue Solution is used to spread the Hallow and is ideal for creating artificial Hallow biomes or expanding existing ones.
Using the Clentaminator and Green Solution is by far the fastest and most efficient way to purify the Hallow.
The Importance of Containment
Before focusing on complete purification, it’s often necessary to contain the Hallow (and other biomes). This can be achieved by creating tunnels at least 6 blocks wide and 3 blocks deep, lined with non-corruptible blocks such as Dungeon Bricks, Ores, Clay, Ash, Silt, or most crafted blocks. These barriers prevent the spread of Hallow and other biomes through direct block conversion.
Frequently Asked Questions (FAQs)
Here are 15 frequently asked questions regarding the Hallow and its management, designed to further enhance your understanding of this complex biome.
1. Can Hallow be converted to other biomes directly?
No, Hallow cannot be directly converted into the Crimson or Corruption using Vile Powder. However, you can directly convert crimson/corrupt blocks into thier hallowed counterparts using the Clentaminator, but it won’t spread beyond the blocks you sprayed unless it’s near a normal convertible block.
2. Can Hallow spread to ice?
Yes, in Hardmode, Hallow can spread through ice, creating Pink Ice. It cannot spread through Snow Blocks.
3. Can the Hallow infect the Jungle biome?
No, the Hallow cannot spread through mud areas like those found in the Jungle or Glowing Mushroom biomes. This makes the Jungle relatively safe from Hallow encroachment.
4. How do I make an artificial Hallow biome?
An artificial Hallow biome requires at least 100 to 125 Hallowed blocks such as Hallowed grass, Pearlstone, Pearlsand, or Pink Ice. This will allow Hallow enemies to spawn and count as a Hallow biome.
5. Will NPCs move out of the Hallow?
Unlike the Corruption or Crimson, NPCs will not move out of the Hallow. In fact, having your base in the Hallow can prevent the evil biomes from encroaching.
6. Can Hallow convert Crimson or Corruption?
Hallow can convert Crimson and Corruption into grass blocks, but it cannot directly convert blocks already claimed by an evil biome. This creates the possibility of Hallow and evil biomes existing closely next to each other.
7. Does Hallow spread faster than Corruption or Crimson?
No, all three biome grass variants spread at an equal rate. There is no biome that is inherently “faster” or “stronger” in terms of spread. However, hallowed grass will overtake crimson grass.
8. Do crystal shards spread the Hallow?
No, crystal shards do not spread the Hallow. They emit a small glow similar to Demonite and Crimtane Ore, but are not a factor in biome spread.
9. Can the Hallow take over the Mushroom Biome?
The Hallow will not affect the mushroom grass blocks in the Mushroom biome. If you are housing the Truffle NPC, you will be fine.
10. What happens if I don’t spawn the Hallow?
If you are playing on a world before 1.2, the game ends either at Skeletron or the Wall of Flesh. Then the Hallow does not spawn at all. Also it could be a glitch. Try destroying Demon/Crimson Altars to spread both Hallow and evil.
11. Does the Dryad like the Hallow?
Yes, the Dryad considers the Hallow to be “good” compared to the Corruption or Crimson, which she labels as “bad.”
12. What are the benefits of having a Hallow biome?
The Hallow, while more challenging for new Hardmode players, is a good biome to farm for Hallowed Keys. It also provides a good area to house NPCs without worrying about evil biome corruption.
13. Can I use Holy Water to remove the Hallow?
No. Holy Water can spread Hallow, but it can’t revert Hallow blocks back to their original form like Vile Powder can.
14. What can I craft with Hallowed Bars?
Hallowed Bars, dropped by Mechanical Bosses, are used to craft mid-Hardmode armor and weapons.
15. What’s the most cost effective way to protect against the Hallow?
The most cost-effective way to protect against any biome spread is to create a horizontal hole, 6 blocks wide and 3 blocks deep, and fill it with non-biome affected blocks like dungeon bricks or ores.
Conclusion
While the Hallow can initially seem daunting, understanding its unique properties and the tools available to manage it makes it much less threatening. By utilizing Vile Powder, Green Solution with the Clentaminator, and building proper containment barriers, you can effectively purify the Hallow and maintain control of your Terraria world. With the right knowledge and preparation, you can confidently navigate this vibrant but challenging biome.
