Removing Corruption

[Pofan]

Hi, im trying to reduce spread of this stuff as much as i can but i'm a bit confused because whenever i clear WHOLE part of Corruption with Clentaminator (probably 3-4 chasms and some tunnels beneath), when i go back to chceck thing out, a new block (or wall) is turning into corruption AGAIN outta nowhere, spreading it like crazy. So i wanna ask where did this corrupted block came from. Is that because chasms are there from start or what? (I know that when you smash Demon Altar, one random block will turn corrupted)

Yeh its a bch, if you dont get every last block it will infect the area almost immediately.

I am currently doing a test if the top crust of the land can become infection free by running a 5 block high tunnel from end to end.

I ended up downloading Terramap and running a scan for all instances of the corrupting blocks. Its the only way imo to be completely sure that you've sprayed everything!

**all it takes is one corrupted block to start spreading corruption/crimson

[bloOdykizZy]

what happens when you're 0% corruption or 0% crimson? I'm assuming nothing.

there's really not much of a point in trying to remove the stuff...you have to have corruption/crimson, hallowed biomes to get all the ingredients you need to make higher tiered stuff.

if you want to "contain it" and stop the spread, basically the most effective way is to dig a hellevator 6 blocks wide. but even that takes forever.

some people claim to have removed it all and gotten 0% but i don't see how that's possible since in hardmode, it pervades all the way down to the core from the surface, you practially have to hit every every block in the entire world to get rid of it. except the jungle of course.

I just learn to live with it, once you get a few hardmode equipments, hardmode is not that "hard"


my advice on "removing the stuff"...don't try, it's too much of a headache.

if you insist on trying, then i would only go as far as keeping it away from my town, although i usually build my town up high above it or dig underground below it and then just let the corruption and hallows spread naturally, they will eventually meet and stop each other

[Pofan]

you've got the point, i wanna contain it, cuz it found my jungle biom, that would be pain in a** if corruption take it all, so i cleared that whole chasm near jungle like i said but it keeps regrowing outta nowhere
P.S. even if you clear whole map, ther are still seeds so you can start all this madness again :)

[★Brosef]

So confirming the results of my test, yes you can contain the infection/preserve certain locations by digging a "trench" around the desired location to prevent complete take over.

[Pofan]

that will take a bit longer but shroomite claw and minig elixir along with mecha glove will do the trick, i guess instead of using clentaminator every single time and waste money will be better to dig around it and countain it like this

We're having a lot of issues with corruption spread in our server at the moment. Purifying powder and clentaminator aren't really working. Basically, a lot of preparation needs to be done before you go into hardmode. We built hellevators, which are keeping a lot of the spread at bay, but it would seem that if you want to stop the thorns spreading the corruption past the tunnels and hellevators you need to fill them with some kind of brick, clay or snow. We've been digging more tunnels and walling bits off with brick but in future playthroughs I think I'll wall off the existing areas of corruption before hardmode so I don't have to worry about it spreading too far in hardmode and make sure that there are plenty of defenses around the main base. Terraria is all preparation and unfortunately if you want to really keep the corruption at bay you need to spend quite a bit of time making sure it's contained.

well that's what i meant when i said "dig hellevators all the way down 6 blocks wide"

the only way to really stop the spread is to remove all the blocks in between the corruption and the area you are trying to protect.
i may be mistaken about the 6 blocks.
i am aware of the reaching throns that grow from the corruption to try and get your blocks, they can only reach so far. myabe you need to make the trench 8 blocks wide or 10, i forget.

of course...then your world looks ugly with huge holes in it lol.

just be glad you don't have to mine dungeon bricks and surround your whole city in a 4 block radius of protective casing to prevent clowns from blowing it up anymore

A 3 block gap is enough actually. Hallow, Corruption, and Crimson can only 'jump' 3 blocks from their source block. If you line/fill the gap with blocks that cannot be converted, such as Brick or Wood, this also prevents things like corruption thorns from possibly spreading it.

[Tangerine]

put a whole bunch of hallow in the area

[Torchfire]

Just making a point, but if you put a rope through the middle of the hellevator shaft, the thorns will not spread through it. That way a 3-block wide shaft is enough to prevent the spread of any cancerous biome.

[Pofan]

thanks for all advices, i just wanna protect jungle from corruption i'm not gonna dig whole map

[ImmortalSausages]

if you want to make your world pure, Heck Better buy out the steampunkers Green Solution :P

yes, the blocks can only jump 3 blocks away but corruption grows thorns which snake their way over and extend the reach., which is why i said you need to make the shaft wider.

...however, i was unaware of the rope trick the next guy just posted, blocking the thorns with rope.
it would take a LOT of rope but it might be quicker that way.
