Crimson and Hallow are out of control. Please help!

[inkxy]

I'm a (relatively) unexperienced new player in a Hardmode world. Before Hardmode,I had sealed off my Jungle on one side from the Crimson, with a giant pit. Now that I'm in a Hardmode, the Jungle is soon to be under attack from the other side as a new Crimson has spawned there. The newly spawned Crimson stretches into my mines, and now mining has become more dangerous. I heard that creating the Hallow can stop the Crimson/Corruption spreading, and doesn't force NPCs to move out. However, now the area around my house is a Hallow biome from my attempts at stopping the Crimson spreading. It's not too bad, but the monsters spawned are severely annoying and killed my dryad. You should have seen how many gastropods there were on a Blood Moon! My other Hallow, the natural one, has taken over half of my Underground Snow biome and will probably spread to take over the whole entire snow biome. My other other Crimson (my world is normal-sized so there were two Crimsons to begin with) will probably spread all the way to my dungeon if I can't stop it, and past my dungeon if I don't put up something to stop it before it gets there. This means that almost all of my deserts will be Crimson, my snow biome will be Hallowed, I have created a new Hallow biome that will soon be spreading uncontrollably and my Jungle will be taken by the Crimson if I can't seal it off. I haven't killed a mechanical boss yet so I can't get the Clentaminator. I need a quick and efficient way to contain my Crimsons and Hallows that doesn't involve creating giant pits stretching down to the Underworld that will take forever and requires ~400 Sticky Bombs and ~20 Sticky Dynamite per pit. Please help me!

The clentaminator might help with that. It can change biomes pretty fast to normal. It's also pretty expensive.

Do remember that the dungeon cannot be converted to crimson/hallow and neither can the piramids in the desert should you have any. They make great barriers for a while. If you go to the lowest point in the dungeon and dig from there you should be able to cut the entire map in 2 parts easily.

Breaking demon altars also releases the crimson on some randon tiles on your map. It's better to live with underground crimson as you can't really remove that without much work.

I could give you a Clentanimator and green solution of you want

[Chaos Undecided]

Defeat one of the three mechanical bosses in a different world if you have to and get the steam punker. The clentaminator may be expensive but it's easily the best solution to your problem, it converts these biomes back to normal in no time. If you need better equipment for the mech bosses, the new world for acquiring the steampunker can be used as an extra source of hardmode ores as well. With this, you can try to kill the three mechanical bosses in your original world, thus allowing you to take on plantera once you've got some chlorophyte gear from the hardmode jungle (after killing the 3 mechs in a world). Killing plantera for the first time slows corruption, crimson and hallow spread by a third, so you cleanup quest will be much more efficient.
Overall, expensive and difficult as it may be, get the clentaminator. It annihilates unwanted biomes.

There are never any easy ways to deal with corruption, it's a major hassle in the game and it was probably designed that way. Your first time around, it's normal to have your world overrun.

Usually, you can dig enough to protect one side of your Jungle before Hardmode (it's a good thing you thought ahead), re-dig to protect the other side if you're unlucky enough for corruption to happen that side too during transition, and get the Clentaminator before things get too out of hand (mechanical bosses aren't that powerful). Then, killing Plantera slows corruption to 1/3 of its normal speed, so you can keep things under control.

Again, if you're inexperienced, you're not going to be killing Mech bosses early enough to stop the corruption. No biggie. You can either function with most of your world corrupt (makes it easier to get Souls), and with a powerful character it's surprisingly easy to install yourself on a new world should you want a clean one.

I was thinking of digging down from my dungeon anyways. The problem is that I haven't killed a Mechanical boss yet and by the time I get the Clentaminator, the Crimsons and Hallows would have spread very far. I need a quick solution that can contain the biomes until I can get the Clentaminator.

The speed at which they spread will be rendered irrelevant by the clentaminator, especially if you get hold of it on a fresh world so these biomes don't spread in your original world.

Okay. Thanks for that.

For each Demon/Crimson altar you destroy random crimson or hallow spawn in your world. SO if you like things au naturel then only break 3 of them.

Next, Hallow stops crimson and is to prefer over the corruption that prevents NPCs from living and a house from being suitable. But as you have observed, it can be kinda tricky to be attacked by laser shooting gastropods and unicorns.

That your underground has become hallowed or crimson actually works in your favour. You can get Souls of light/night and fight hallowed/crimson mimics. So that's a good thing. And completely normal. I think Mushroom biomes cannot change so that's always a way to create a barrier between you and the underground.

Last but not least. The Clemanator is by far the best way to prevent spread, the other one is to defeat Plantera. Defeating Plantera reverts the spread to the speed of a normal world instead of the new faster one.

Hallow and crimson, if they were to meet, hallow would take over crimson/ corruption. also, put 3 block-wide pillars infront of the crimson and hallow that is around 10 blocks deep.

So, then youre NPC are safe, go and farm some titanium/adamantite ores, make another world if you need, and kill the twins, buy a clentaminator and fight the corruption/crimson. In 1.3 Clorophite ore is a barrier againts the corruption/crimson, so youre jungle are not in real danger.

sounds like you need some T4 rockets fired at most of your world.

Why not make it 99% hallow and 1% crimson or normal grass biome
