The short answer, and a common point of confusion for many Terraria players, is yes and no. While directly breaking an altar does not instantly create large swathes of corruption, it plays a significant role in facilitating its spread. Let’s delve into the mechanics and clear up any misconceptions.
Essentially, every time you smash a Demon Altar (in a Corruption world) or a Crimson Altar (in a Crimson world), you trigger a 2/3 (66.67%) chance that a single random Stone Block deep within the Cavern layer will be converted. This block will change into Ebonstone (for Corruption worlds) or Crimstone (for Crimson worlds), or even Pearlstone if you’ve defeated the Wall of Flesh and entered Hardmode. This initial change acts as a seed, providing a new point from which the corruption (or Hallow) can begin to expand.
It’s crucial to understand that altars themselves are not counted towards the corruption percentage of a world, and they don’t directly “spawn” large chunks of corrupted biomes. However, they are the trigger for the chain reaction that allows existing corruption to spread more readily and create new pockets of evil biomes.
This process of converting a single block might seem minor initially, but this is an essential part of the progression that takes place in Terraria after defeating the Wall of Flesh, as these newly converted blocks can quickly grow, especially if there are soft or corruptible blocks nearby. For example, nearby snow, sand, or mud tiles will quickly become corrupted. Understanding this mechanic is key to managing the spread of corruption and maintaining control of your world.
Understanding Altar Mechanics in Terraria
The Role of Demon and Crimson Altars
Demon Altars (found in Corruption worlds) and Crimson Altars (found in Crimson worlds) serve two primary purposes. First, they act as crafting stations that allow the player to create specific items, particularly those needed to summon bosses early in the game. Second, and most importantly for this discussion, they are the key mechanism for introducing the Hardmode ores into your world.
The Connection to Hardmode
Once you defeat the Wall of Flesh and enter Hardmode, your world undergoes significant changes. One crucial change is that when you destroy an Altar, it will generate Hardmode Ores in the world, allowing players access to the higher-tier ores and weapons. These new ores are Cobalt/Palladium, Mythril/Orichalcum, and Adamantite/Titanium. The generation of these new ores is tied to the breaking of Altars and the spread of Corruption/Crimson/Hallow.
The Spread of Corruption (and Hallow)
It is crucial to note that the primary mechanism of corruption spread is tile-by-tile. Once an Ebonstone, Crimstone, or Pearlstone block is created, either by the world generation or when breaking an altar, it will convert nearby susceptible blocks. The Hallow works the same way, converting blocks to pearlstone, albeit a little slower.
This is why simply smashing a few altars can lead to considerable spread of the Corruption, Crimson, and Hallow, even if it doesn’t directly spawn large areas itself.
Frequently Asked Questions (FAQs)
Here are 15 frequently asked questions related to breaking altars and their impact on corruption spread in Terraria, to further solidify your understanding:
1. Does breaking a Shadow Orb or Crimson Heart also spread corruption?
Yes, breaking Shadow Orbs (Corruption) or Crimson Hearts (Crimson) also triggers the same single-block conversion mechanic as breaking altars. It does not cause large areas to be corrupted, but like altars, these blocks will initiate the expansion of corrupted biomes.
2. How many altars should I break?
It’s generally recommended to break at least 6 Altars to guarantee that all three tiers of Hardmode ores spawn. However, be aware that this also increases the potential spread of the Corruption or Crimson. Breaking 3 is an option to reduce the infection, but it might be difficult to find all the ores you need in the early game.
3. Do altars count towards the corruption percentage?
No, altars themselves do not count towards the corruption percentage of your world. The percentage is determined by the number of corrupted blocks present, like Ebonstone, Crimstone, Corrupt Grass, etc.
4. Are Demon Altars easier to find in the Corruption?
Yes, Demon Altars are more likely to spawn within the Corruption due to the vast caves and Chasms it generates. But they can also spawn elsewhere.
5. Can I purify corruption once it spreads?
Yes, you can purify corrupted areas using Purification Powder, Holy Water, or more effectively, the Clentaminator with green solution.
6. Can the Jungle be corrupted?
Yes, the Jungle is highly susceptible to corruption. Because of the many mud blocks, corruption spreads quickly there. Snow biomes and Deserts are also easy to infect.
7. Can the Corruption spread to the Crimson, or vice versa?
Yes, while they are typically generated as alternatives at world creation, you can create Crimson in a Corruption world, or Corruption in a Crimson world. Their spread is not inhibited.
8. Does the Hallow spread slower than the Corruption or Crimson?
The Hallow does spread, but it spreads slower than Corruption and Crimson. It serves as a good counter to the spread of these biomes and a safer alternative to your normal forest biome.
9. Can I prevent corruption spread altogether?
You can’t completely prevent the initial spread when breaking altars or orbs/hearts, but you can create Hellevators (vertical tunnels lined with non-corruptible materials like stone brick) to act as firebreaks.
10. How do I find the Pwnhammer to break Altars?
The Pwnhammer is dropped by the Wall of Flesh. This is the only hammer capable of breaking Demon and Crimson Altars.
11. Can Corruption spread through walls?
Corruption or Crimson cannot spread through non-corruptible walls. Natural walls that are placed by the game during world gen are corruptible. Player placed walls are not corruptible.
12. What is the best way to contain the spread of corruption?
The most effective way to contain the spread of corruption is through strategic use of Hellevators around your base and important biomes. This combined with the Clentaminator and non-corruptible tiles, will allow you to contain biomes that you want or do not want.
13. Does Demonite ore spread Corruption?
No, Demonite ore does not spread the Corruption. It can be found in higher quantities within corruption caves.
14. What is the difference between Corruption and Crimson?
Corruption is generally considered to be easier in the early game but has weaker loot overall. Crimson has harder early enemies but has better Hardmode loot, like Vampire Knives.
15. What does an Altar of Corruption do?
The Altar of Corruption, found within the Corruption biome’s dungeon structure, is a device that allows players to corrupt an item. It will change an item into a different item using random modifiers. This is similar to using a Vaal Orb in Path of Exile, where you have a chance to transform an item.
Conclusion
In summary, while breaking an altar doesn’t directly create huge swathes of corruption, it is an integral part of its spread because of the single block conversion it triggers. Understanding this process, combined with strategic use of purification methods and firebreaks, will help you maintain control of your world as you progress through Terraria. Now armed with this knowledge, you can proceed with a greater understanding and control, ensuring a better experience of the game.
