In all environments pages there are these repetitive "inside the" and "found in the" etc., i think that should be deleted, not sure though --The preceding unsigned comment was added by Bow Artist3 (talk • contribs) at 13:18, May 23, 2011 (UTC).

I agree. Unless we eventually learn a lot more about the specific biomes, I'd say they all get merged here and redirected when searched for. MarekkPie 14:50, 23 May 2011 (UTC)


A merge has recently been suggest for this page. I am against it, simply because it is too soon. I think we have to wait and give those pages a chance to be stand alone. Worst case scenario, we merge later. By merging too soon, we undermine the individual page's chance of becoming a full fledged article. Happypal 15:28, 23 May 2011 (UTC)

I just want to add that I don't like this idea either - having long wordy articles with many many subcategories is fine for some things, but can also be extremely cluttered looking, especially if each section has screenshots and the like. And also, yes, the game is still very in development, lots of things are likely to be added quite soon for each section. --FungusTrooper 15:49, 23 May 2011 (UTC)
As I stated under meteorites, look a the Ore page along with the subsections for how I believe the Environments page should work, a small article with minor notes on the biomes then subpages for each environment. -Shadowclaimer 16:20, 23 May 2011 (UTC)
I'm not saying it would a merge would be the wrong solution, I'm just saying it is too soon for such a big change. Ore is just a block, and there is not much to say about it. An environment, on the other hand, I can see growing into great articles, with images and tons of things. If it turns out I'm wrong, then a merge would indeed be the right solution; merges are easy, un-merges are hard.
That said, I see nothing wrong with presenting the environment page like the ore one, with a little subsection and a link. Happypal 18:39, 23 May 2011 (UTC)


I am proposing a move of the pages Deserts, Forests and Floating Islands/(+subpages) to Desert, Forest and Floating Island. Why? apart from the fact that a wiki page about something should be singular, every other environment is also singular. This page (Environment, as of this edit), is also singular. Wikipedia does it this way too for Forest, and even Floating island. It's just the standard way of doing things. Happypal 06:40, 27 May 2011 (UTC)

We aren't Wikipedia, we don't follow Wikipedia rules. -- Wynthyst File:Curseicon.png talk 06:48, 27 May 2011 (UTC)
What rules do we follow? What is your explanation for Dungeon, Meteorite, Underground, but Deserts, Forests and Floating Islands?
I really don't think anyone cares as long as there are appropriate redirects (which there should be) --Colonel Thirty Two 23:29, 30 May 2011 (UTC)
Those who have an unhealthy obsession with consistency/uniformity care, such as myself :) It's something of a mixed blessing. I know this topic is ancient, but ya... I agree with Happypal in preferring singular to plural. My reasoning, in the hopes of influencing future page titles:
  • keep things as simple as possible;
  • plurality is a longer and more complex variant than singularity;
  • fewer redirect pages;
  • people's eyes aren't constantly catching on the "(Redirected from Foo)" line on their way from the title to the intro paragraph;
  • Wikipedia precedent;
  • there's an inherent beauty in consistency—though I appreciate diversity and variety in art and nature.
I'm certainly tempted to add 'move' templates to dozens of pages, but I'd just end up annoying all the "normal" people out there for whom consistency is a non-issue. I guess I just always like to feel as though some kind of perfection is being approached, which is why I find wiki editing rather addictive, and why I always spend so much time refactoring code.

Floating Islands

Floating islands aren't really a biome. The entire sky up to a certain hight not above the center of the map is the sky biome. The biome is actually the mostly empty vast space where harpies spawn. The floating islands are just a part of it. --Moxxy 17:01, 2 July 2011 (UTC)

Defining a Biome

What exactly defines a Biome? Sometimes removing the background destroys a biome and sometimes removing walls or adding stones destroys a biome. My example is based on the dungeon biome, where i currently have the phenomenia that when i remove walls nothing changes, but when i remove the backwall, the biome gets destroyed. On the contrary, placing enough corrupted stones will make any biome partly corruption, with spawn and music around a certain high (which i have yet to determine, sorry). So what is youre idea? --Preceding unsigned comment added by Faya (talk • contribs)

It's mostly nearby tiles, depth, and occasionally, background walls. For example, a certain number of jungle tiles means it's a Jungle, but at a certain depth, it's an Underground Jungle instead. A Dungeon is a Dungeon when there's 250 Dungeon-only bricks nearby, the player is at 0 ft or lower, and the player's standing in front of an unsafe background wall, not including no background wall. --Lunboks 12:35, 12 September 2011 (UTC)

Corrupted/Hallowed Desert, should they be added?

Both basically are real biomes on their own. They even have their own backgrounds and enemies. If at all, it wouldn't be more than a sub-sub-section, but I'm wondering if this should be added at all? - Selbi 22:55, 9 December 2011 (UTC)

Are you sure that they have "own" backgrounds? In my opinion it's just recolored standard desert background with overlayed rainbow in hallowed case.
Yes, they do. "Just a recolor" still makes them a full background design on their own. - Selbi 17:21, 13 December 2011 (UTC)
Personally I think we should put in sub-biome stuff for Hallow/Underground Hallow/Hallowed Desert, Corruption/Underground Corruption/Corrupt Desert, Jungle/Underground Jungle, and Floating Island/Space. --Theothersteve7 20:43, 13 December 2011 (UTC)

Snow Biome's resistance

From mine and a friend's experience, I find that Corruption very happily spreads over Snow Biomes; is this right? Every snow-related page claims that snow is resistant to both Hallow and Corruption (it is resistant to Hallow AFAIK)... MKSTAR26 12:31, 18 February 2012 (UTC)

The comment about the Snow Biome being always opposite the jungle is incorrect, at least in the current version. Playing on version on PC, a small Snow Biome generated in my map that was quite close to the jungle. At least, much closer to the jungle than it is to the Dungeon. Approximately halfway between the spawn area and the Jungle, separated by a Forest and a Corruption zone. 05:10, 4 November 2013 (UTC) ~

Artificial biome don't change background?

Haven't played too much, just created a jungle right in our settlement, the music changes, sky color became a little more yellow/green, just like in a real jungle biome, and of course, enemies. But the background pictures didn't change, but to be honest, I can't remember if the jungle has its own background. But today I made a western-themed settlement and I put sand all over the place, works fine, vultures and those sand spitting bugs spawned, but the background is still green forest. It would be nice if the background picture will change too, making it really looks like a desert without trees. Anyone got it to work? Should I just put more sand there? I only got 1 tile thick sand, which is enough for creatures/cactus to spawn.

More sand should work. I think the background changes depending on the proportion of a biome on-screen (and perhaps slightly off-screen), so you should get at least enough sand so the bottom row on your screen is sand. Of course, you can just add layers until it changes... -- 02:42, 22 March 2012 (UTC)
Okay, I will give it a try, but does this depends on how big the window is? what if I play in fullscreen? When I created the jungle, I only put 1 layer of mud on the original dirt ground, but it works fine, maybe because of those trees and grass?

EDIT: Tried with Map Editor, it works, now I just need to find out how many sand block do I exactly need.


I'm working on reorganizing and recategorizing this page as of 1.21. Now that many biomes are fully implemented the distinction between major and themed doesn't make as much sense to me. I am thinking of breaking up the page into Surface, Underground and Hardmode biomes, but I won't make any changes until I test it out first. I also want this page to include easy links to special biomes and unique features (like the pyramid) since it's a directory page, right? -- Camelotcrusade (talk) 20:01, 5 October 2013 (UTC)

There, I reorganized it! I hope you find it easier to follow now. -- Camelotcrusade (talk) 00:11, 6 October 2013 (UTC)

Jungle Biome requirements changed

I believe the requirements for a jungle biome have been changed to 300 jungle grass, vines, or bushes. To test this, I created a 40x2 mud platform and planted jungle grass seeds on it. Even after all 80 blocks had grass on them, and the platform was overgrown with vines, bushes, and grasses, nothing jungle related spawned. I then increased the size to 100x2 and still nothing spawned. Then I increased again to 150x2 and once that grass grew, jungle mobs started spawning. I wanted to test that bushes and vines still counted for determining the biome, so I decreased the size to 125x2 and kept everything trimmed. Mobs stopped spawning when the jungle was cut back, and started spawning again when it became overgrown again. 02:55, 8 July 2015 (UTC)

How large was your test area? I built a Jungle grass mini-arena with just around 80 mud blocks (about 20 for sidewalls and 40 for the ground), and I believe that even with all vines trimmed and bushes cut, I retain the Jungle music and background inside it, as well as the ability to use Abeemination to summon Queen Bee. I will see if I can re-verify the number of blocks a bit more carefully, but I am completely convinced it does NOT need 300. Esaelon (talk) 16:56, 8 July 2015 (UTC)
The test area I created was a 40x2 mud block platform completely covered with jungle grass. I should point out that what prompted me to make this test area was the fact that I created a fishing tank made with about 90 mud blocks with jungle grass and was not able to catch jungle related fish, such as neon tetras. When I created the 80 block test area and got nothing, I was convinced that 80 blocks wasn't enough. Perhaps there is two levels of biome, a bare minimum one where you can perform basic biome related functions, and a higher threshold where you start actually spawning monsters and being able to catch biome fish. 00:40, 11 July 2015 (UTC)
Regarding the spawning of fish, my experience has been that if you are at a location where your background / music changes to the biome, and there isn't another higher-priority biome in range of you, then you can catch the relevant fish. How the game handles biomes for fishing and for monster spawning seems subtly different, but I have not figured out how monster spawn determination works at all, yet. Esaelon (talk) 01:35, 11 July 2015 (UTC)

Snow Biome rename?

I've noticed that the Angler quest descriptions in 1.3, where it refers to where to locate quest fish, refer to the Snow biome as 'Tundra'. Given this appears to be the official name for the biome, should we rename all references to it on the wiki? Esaelon (talk) 05:09, 9 July 2015 (UTC)

Weird shadow biome

I once saw this weird biome we’re everything was black I don’t know why it was there but it was very unique Hantedarmor2345 (talk) 15:14, 18 February 2020 (UTC)

Should We Change the Name of "Ice biome" to "Ice"?

Should we change the name of ice biome to ice? Changing the name would make it parity with all the other biome names. — Preceding unsigned comment added by MattTheBanana (talkcontribs) at 02:56, 14 April 2020 (UTC)

Indeed. I removed it from the heading. Please remember to sign your talk page posts with four tildes (~~~~). --Rye Greenwood (talk) 13:11, 14 April 2020 (UTC)

Underground desert

The majority of the underground desert actually takes place in the Underground layer, not the Cavern layer.--Superwill771 (talk) 14:35, 4 May 2020 (UTC)

Wiki Biome banners.

How are we getting these banners for the biomes? Can we make some for the new mini-biomes? --Superwill771 (talk) 16:29, 17 May 2020 (UTC)

They're just edited in game screenshots. I'll try and get some up later. --Eraloiz (talk) 16:33, 17 May 2020 (UTC)

1.4 Biome Requirement Changes

The amount of blocks necessary to make artificial biomes was changed going from 1.3 to 1.4: In particular, snow biomes now require 1,500 blocks of snow/ice instead of 300, and corruption now requires 300 ebonstone instead of 200. All other biomes should be tested to see if their requirements have increased as well.

A friend streamer, Kinam Krindar has encountered an oddity where the torch god's blessing isn't counting a large mass of sandstone below and above a tunnel he's building through the underground desert biome as desert now, despite there obviously being enough sandstone to count as a biome. He says it stopped counting as soon as he destroyed the back wall. On the flip-side he was able to create an artificial surface and shallow underground desert for fishing using 1500 sand and hardened sand. Something seems up.
He also did some testing with the Marble and Granite mini-biomes, and it seems now that the requirements there have changed as well. Now you don't just need a single block to spawn mobs. You need at least a certain amount of unsafe marble/granite back wall respectively nearby to spawn the mobs. They will not necessarily spawn at the back wall, nor do you need to place the blocks at the back wall or stand in front of the back wall to spawn them. The back wall just has to be nearby. This means you cannot just set up a mob farm just anywhere for these mobs anymore. You must set it up where you have an existing biome. However, the technique of standing on some granite or marble to supercharge the spawnrate still functions, and if you backwall a large section with your own backwalls, you can ensure that mobs will only spawn where you want them. --ChthonicOne (talk) 21:49, 23 June 2020 (UTC)
Got a clip now. This shows that in the cavern layer it seems that Desert seems to require a back wall to have a biome. At least according to the torch god's blessing. --ChthonicOne (talk) 22:50, 23 June 2020 (UTC)

1500 sand blocks above ocean?

Would it count as a part of Ocean and override the Desert? Asking for an above ocean Desert Key farm. — Preceding unsigned comment added by at 20:09, 1 July 2020 (UTC)

Yes, it would count as an Ocean, even if you used e.g. Hardened Sand blocks: Desert Keys will not drop if the player is located in the Ocean biome (that is, horizontally roughly 380 tiles from either end of the map, and vertically above roughly the Underground layer). (Information taken from the Desktop version Desktop source code, class DesertKeyCondition in Terraria.GameContent.ItemDropRules.Conditions.cs There may be inaccuracies, as the current Desktop version Desktop version is - Fistsh (talk) 22:27, 1 July 2020 (UTC)

How big is this "area" the wiki is talking about?

On all of the wiki pages about biomes, they all talk about "X blocks inside an area" I'm currently trying to clear out a large piece of the corruption to put a town inside of it, but i can't find how big this "area" is, i've looked on every page i could think of to find how far away the corrupted blocks need to be.

Does anybody know in what range blocks affect biomes? ZeanZarzin (talk) 16:25, 3 November 2020 (UTC)

It is there at the top of the Biome Existence Requirements section on the Biomes page. 85 to each side and 61 below/64 above for PC/mobile and 50/42/44 for other platforms. Metalax (talk) 10:48, 4 November 2020 (UTC)
Shouldn't we move it to the top? Putting the "biome existence requirements" section under "Hybrid biomes" is kind of wierd, since it applies to the whole page and it's rather important. ZeanZarzin (talk) 10:48, 6 November 2020 (UTC)
Moved it out of Hybrid Biomes to its own section. I feel it should still be after all the actual biome sections on the page however. Metalax (talk) 16:14, 10 November 2020 (UTC)

Possible new Micro-Biome

Biome 1.pngBiome 2.pngBiome 3.pngBiome 4.png

This could be mere chance, since I probably play this game too much, but I found what looks like a new micro biome. There was a 1-tile wide gap going downward from the surface, similar to an Enchanted Sword Shrine. The gap reached about 75% of the way down to the small cave here, which had 2 antlion eggs about equidistant from the entrance. Digging a little further produced a larger cave that didn't look too out of the ordinary. I dug all the way to hell and there wasn't anything noteworthy. There was no loot from this supposed micro biome, but the 1-tile gap going through the middle of the hill look kind of weird to me. NaughtyPhy (talk) 06:43, 19 December 2020 (UTC)

As shown on this screenshot which shows different Desert top generations, it seems to be a common anthill hole which was linked to a small room which was itself connected to another. I have no doubt that burrow around it will reveal other caves from the Underground Desert biome. Also, as you stated, it doesn't have anything out of ordinary to be noteworthy. --Dinoxel (talk) 13:01, 19 December 2020 (UTC)

Separating biomes and structures?

Currently biomes and structures are listed on the same page. Should there be a clearer separation between them and divide them into two pages? Something like "Biomes refer to areas that contain unique tiles and cause unique (non-Boss) creatures to spawn naturally, while structures refer to areas that only contain unique combinations of tiles".

In this way, Bee Hives and Oasis should be classified as structures, since they do not contain unique creatures that only belong to that place. --BadPiggy1024 (talk) 08:04, 17 April 2022 (UTC)
