Resistant Blocks
Can we clarify what is meant by resistant blocks? Are the blocks merely resistant, i.e. they will be converted eventually, just at a slower pace, or are they actually immune to being corrupted? - Spinfx 04:29, 8 December 2011 (UTC)

The entire world is changed?
I'm very hesitant to summon the WoF because it seems the entire world will change into hallow and corruption. Is this correct? No more forests, Jungles, deserts? This seems so lame... so it can't be right. I wanted to ask folks how much of your world was changed to Hallow/Corruption.


 * Firstly, the change is gradual, not immediate. You gain one Hallow biome somewhere, and the corruption and Hallow biomes will start spreading through stone and sand as well as grass.  Next, all creatures that occur in woods also occur in Hallowed woods.  Deserts will gradually become either Hallowed deserts or Corrupt deserts.  The jungle will probably be preserved - the Corruption can take it over, but the Hallow will not, so make sure you spread Hallow around its edges.  The Dungeon and Underworld remain unaffected, and floating island are safe.  All in all, yes, you lose a bit when you go to hardmode, and it's probably best to keep a pre-hardmode copy of your favorite world, but you gain far more than you lose.  --Theothersteve7 17:24, 13 December 2011 (UTC)


 * I see, thanks. I'm attempting to dig some vertical tunnels so that I have vertical strips of hallow/corruption and the outside edges of the world are still normal. Also digging a 3-block wide trench around my home area so it remains unaffected. Will report on its effectiveness, wish I had a compass to give exact measurements. 76.182.95.123 17:10, 13 December 2011 (UTC)


 * Preserving the surface is a bit easier. Hallow and Corruption don't spread through dirt without grass (except in the way that grass does).  So you can simply build something on top of the soil, kill off the grass underneath it, and you've made a surface barrier.  I should upload some pictures.  --Theothersteve7 17:24, 13 December 2011 (UTC)


 * From what I've read elsewhere on the wiki, the Dungeon is also unaffected by the Hallow/Corruption, and since it extends from the surface down to nearly all the way to the Underworld, it is a natural barrier of sorts (you may wish to dig a vertical airgap from the bottom of the dungeon down to the Underworld to complete the "barrier").
 * On a side note, yeah, I'm in no rush to activate hardmode either. Been spending a lot of time digging huge airgaps around my base and farms. While tedious, it gives me a sense of satisfaction that nothing, and I mean nothing, will be able to jump across my 20-block gaps. Try to get at my base now, Hallow/Corruption. Ha! - Spinfx 01:08, 23 December 2011 (UTC)


 * I'd like to chime in about Floating Islands being untouchable - I've had Corruptors follow me up there and shoot Vile Spit, corrupting it pretty quickly. Your 20-block gaps won't mean jack unless you build a wooden barrier or something of the sort to fence those suckers in.68.127.28.221 01:42, 23 December 2011 (UTC)


 * I've mined out all the floating islands a long time ago (didn't want to waste meteors crashing there) and my surface outposts are high towers. Corruptors won't be spitting into my territory any time soon. EDIT: You guys still leave your floating islands hanging around? It takes, what, 10 minutes with some explosives to get rid of one (the backwalls can be ignored). The only way Hallow/Corruption is getting into your safe area is if smashing the demon altars generates Hallow/Corruption there. - Spinfx 02:50, 23 December 2011 (UTC)


 * Me and my friends beat the Wall of Flesh on Xbox recently, and my world gained hallow, but I hate the world now because the Corruption was a big problem, so I planted Hallow to contain it, but the Hallow spread like crazy and I lost every NPC except the Dryad. I created a new world and before I fight the WoF I'm gonna cleanse the world of the Corruption and, in Hardmode, the Hallow. I would reccomend that you cleanse the world of Hallow and Corruption to keep from losing the jungles, deserts, ocean, etc. Terrariatrooper9 8:05, 23 July 2013 (UTC)

Generation of Corruption/Hallow
On the console version, it appears that the forces of light and dark erupt where the Wall of Flesh first appears, and the corruption spreads in the direction the WoF is moving. So if you summon the WoF for the first time on the left-hand side of the map, and it's moving to the right, you get a long strip of corruption but only a small amount of hallow. Also, hallow seems to overwrite pre-hardmode corruption entirely, converting it to hallow but then being unable to spread.

This may allow players to control the way these biomes are generated and what they intersect - putting the dungeon in the way of corruption while the hallow points at existing corruption could significantly tilt the balance of the world. More testing is needed; third-party verification (especially on PC) would be helpful.
