Talk:The Corruption

Merged into the Environments page
This article, while well written, is so small that I'd say we merge it - along with all the rest of the biome pages - into the overarching Environment page. MarekkPie 14:58, 23 May 2011 (UTC)


 * No No, against it. Overview Pages with links to more specific ones are fine (except we are talking about armor pieces or mob size variations) – Flying sheep 20:14, 25 June 2011 (UTC)

"The" Corruption
May I ask why exactly is it "the" Corruption? Why not just "Corruption"? --Demian 17:15, 26 May 2011 (UTC)
 * It is not a common occurrence compared to the actual amount of land that is on the server, it is also randomly generated as a separate "entity" if you will as it causes a complete environment change. At least that is how I see it.--Thanatos 18:51, 26 May 2011 (UTC)

Thorny Bushes
We should somehow explain that these grow here. – Flying sheep 20:14, 25 June 2011 (UTC)

Monster Spawns
I think the page should say how much corruption grass or ebonstone it takes for monsters to spawn or for Eater of Worlds to be fought.

Corruption "spread"?
It's not very clear what it means when it says sunflowers can be used to stop the corruption from spreading. The article doesn't talk about spreading anywhere else, so I don't quite understand what that means. Is this something the biome itself does? Is it possible - if you were to remove all sunflowers from your map - to turn the whole world into a corruption biome? Or is this just referring to those purple viney corruption bushes? How fast is the spread? Is there a limit to the distance it's allowed to cover? I think there's a lot left uninvestigated here 98.151.233.238 09:16, 13 August 2011 (UTC)
 * The spread is just the purple grass. It spreads, like basically any other sort of grass in the game, but it can also spread to dirt blocks that already have normal grass on them. It's true that Sunflowers planted on grass stop this spread, but so does a single block that's not dirt. The real function of Sunflowers seems to be offsetting "evil" tiles -- if one plants 40 Ebonstone blocks and 1 Sunflower, the sky would remain normal. --Lunboks 11:20, 13 August 2011 (UTC)
 * I just added a section that differentiates between 'Corruption' and 'The Corruption' terminology that will hopefully clarify this.  Equazcion ( talk ) 11:23, 13 Aug 2011 (UTC)
 * PS to answer your questions, there is no real limit to how far Corruption can spread, but naturally-occurring Corruption areas created during World generation seem to be limited to their original areas. Corruption can also be started using Corrupt Seeds, and I don't believe that is limited -- any contiguous dirt blocks will eventually develop Corruption. A Sunflower placed in the path of Corruption will act as a border where Corruption can not spread past.  Equazcion ( talk ) 11:26, 13 Aug 2011 (UTC)

Extent to how much the Corruption can spread / be stopped
We should discuss the extent of which certain items can spread / stop the Corruption. Some of these items include: The modes involved are pre-Hardmode and Hardmode.
 * Purification / Vile powders,
 * Sunflowers,
 * Hallowed / Corrupt seeds,
 * Holy / Unholy waters.


 * Whether sunflowers / Purification powder will still stop corruption in pre-Hardmode (as of v1.1)
 * Whether spraying Vile powder / Unholy water, or planting Corrupted seeds in The Hallow will cause corruption

Any comments? Dragomir7 04:05, 4 December 2011 (UTC)


 * Here's what I've figured out:
 * In normal mode, corrupt grass can spread anywhere regular grass could (dirt blocks with at least 1 exposed surface above a certain minimum depth), and can displace normal grass unless that normal grass has a sunflower planted in it. Naturally-occuring corruption will probably have its progress halted by various natural barriers before you even discover it.
 * In hardmode, corruption can displace normal grass even if it has a sunflower on it (the sunflower is uprooted, just as if a player had mined the dirt underneath). It can also spread through stone and sand, turning them into ebonstone and ebonsand, respectively.  It doesn't appear to corrupt ores or any artificial blocks (wood, bricks, glass, etc.), but it can now cross virtually all the natural barriers that would have stopped it in normal mode, both on the surface and (importantly) underground.
 * Direct contact does not seem to be required in hardmode; it looks like it jumped across my hellevator (2 spaces wide air gap). I don't know yet whether it can jump across uncorruptible blocks or only air gaps, or exactly what the range limit is.
 * The wiki page says corruption can gradually convert mud into dirt in order to spread through it. I have neither confirmed nor disproved that.
 * Hallow seems to spread according to analogous rules, except that sunflowers can grow on hallowed grass, so they don't get uprooted. I also suspect it spreads a little more slowly than corruption, but it's hard to be sure.
 * Additionally, hardmode corruption spawns corruptors, which have a projectile attack that they aim at players but that will corrupt any ground it happens to hit. This can even corrupt hallowed areas, so be careful fighting at the borders of corruption that you'd like to contain, even if the area is already hallowed.
 * Purification Powder will convert corrupted grass, ebonstone, or ebonsand back into their uncorrupted versions. (Of course, the corruption can always spread to them again.)  Hallowed Seeds can only be planted in dirt (not grass, stone, etc.); if planted underground (where grass normally can't grow), the hallowed grass won't spread, but it can still turn nearby stone/sand into pearlstone/pearlsand and create a hallowed biome.  Holy Water hallows any blocks that have hallowed versions (dirt, grass, stone, sand), and can even be used directly on corrupted blocks (though a small patch of hallow surrounded by corruption doesn't buy you much).  A single hallowed seed makes 5 vials of holy water, so this is a much more cost-efficient way to spread hallow as soon as you collect a bit of Pixie Dust.  I haven't used vile powder, corrupt seeds, or unholy water, but I would expect them to follow analogous rules.
 * I'm pretty sure it should be possible to build some sort of barrier that will stop the spread of corruption without resorting to hallow, but it looks like it may need to be fairly thick, and it would need to completely surround the corruption (including underground) to contain it. Since hallow spreads on its own, it is by far the easiest containment option.
 * Of course, you need both corrupted and hallowed areas in the world to farm all the crafting materials you'll want, and hallow appears to be only marginally less dangerous than corruption, so a roughly 50/50 split may be ideal anyway. --Manxome 08:14, 7 December 2011 (UTC)


 * This is a very good post with a lot of accurate and helpful information. I'd say all of this information should definitely be in the article. I have only one thing to add. Corruption will convert mud and jungle grass into dirt, and then corrupt it. Hallow does not have this effect. --GauHelldragon 08:29, 7 December 2011 (UTC)

Spreading
Can the Hardmode Corruption spread through a 2 block wide tunnel of air? --Mister X 14:16, 6 December 2011 (UTC)


 * Yes. At least, that is what I infer happened, judging from the aftermath in my hellevator, which was close to pre-existing corruption on only one side and now has large, matching swathes of ebonstone on both sides. --Manxome 07:47, 7 December 2011 (UTC)
 * This could be due to Corrupted Thorns, which spread the corruption too. 71.87.116.224 07:50, 7 December 2011 (UTC)
 * Corrupted thorns do not sprout directly from ebonstone, as far as I'm aware, and this was too far underground for corrupt grass. I also think I would have noticed if the hellevator was choked with corrupt thorns when I first discovered the ebonstone deposits.  And it didn't cross on the surface and spread downward, since I blocked the corruption's spread on the surface and there's hundreds of feet of regular stone above (and below) the ebonstone. --Manxome 08:20, 7 December 2011 (UTC)
