How to prepare for corruption spread

[TreehouseFalcon]

I've been looking at some youtube tutorials for this topic but they prepare for the spread AFTER they kill the Wall of Flesh. How do I make sure that corruption doesn't spread BEFORE defeating WoF?

Collect money, prepare to buy clentaminator, and much, much ammo for it. And go for cleansing spree.

Also, just a theory - dig out everything around it.

[Serilum]

Just place some sunflowers at the edge.

Sunflowers decrease the spread, my old school way of stopping corruption is placing a 4 block barrier of snow between the corruption and everything else. Snow can't be corrupted, but ice can.

It helps to dig a 3 blocks wide trench to seperate the existing corruption/crimson from the rest of the world. But it will corrupt a part of the world when WoF bites the dust.

General recommendation: Rush for second or third tier gear, fight a mechanical boss and buy the clentaminator gun. Then you can use tunnels and trenches to clean the entire corruption screen by screen. But you need to hurry, or it'll get near impossible to do that for the new corruption.

All you can do is create 4 wide trenches from surface to hell near the existing corrupted biomes. Once the hallow and corruption are spread you have to find it and to the same. The problem is that they spread pretty fast.

And destroying the altars sometimes create a small hallow/corruption somewhere on your map. Getting your map corruption free is near impossible. I always just protect my base and a few area's and put out artificial biomes if i think i need them. The corruption/hallow will take over your world so you better live with it as best as you can.

So should I do this before or after I beat WoF since there's new corrupted areas?

You can do it before to stop the current corruptions from spreading right after you start hardmode. Once in hardmode they spread too fast to do this right. It does take some time, even with a char that mines over 10k cubes within minutes.

Spread the magic green die!

Personally I just build a 3 wide trench around my house/base/NPC town, separating it from the rest of the world, and let the corruption/crimson/hallow spread free. You can always make another world if you need drops from certain biomes that have been corrupted in your world. The trench around my NPCs will keep them happy and corruption free so they don't move out.

Screw clentaminating, waste of time and money unless you've secured big plots. What I do most of the time is just dig out 3 block wide tunnels around the crimsons/corruptions, it takes some time but it's somewhat worth it, just be careful not to leave a block somewhere.

I usually just go ham with bombs on the edges of the corruption/crimson before WoF and in hardmode spam hallow everywhere as I quite like it. I just separate my base from all of them so it stays green.

Be careful, jungle will be overwritten by hallow and corruption/crimson!

[Shamanalah]

Am I the only one not bothered by the spread of the corruption?

I mean.... except for gathering normal woods, forest biome are kinda useless (are there unique fish to that biome? I'm not 100% sure about that...)

Edit: I'm always making sky fortress too, my bases never touch the ground and have like 10 blocks at least from the ground lol :P

Spreading the Hallow (by planting some of it's blocks underground) on top Purity next to the Corruption or Crimson can stop it's spread entirely, at least on the surface. The Hallow overcomes anything.

I don't really think the Jungle can be overwritten by other biomes because of it's importance. I've had multiple saves where the Corruption spreads right next to the jungle biome, but the jungle always remains untouched.
