Talk:The Hallow

In my opinion, it would be appropriate to create a separate page for the Underground Hallow, since the enemies and the environment down there are very different from the surface. Just like there are separate pages for the Jungle and the Underground Jungle. What do you think ? --Tcas 10:25, 3 December 2011 (UTC)

Yes. Enemies don't seem to drop souls of light/night in the aboveground Hallow/Corruption respectively. Also, it looks like hallow/corruption on the surface don't spread downward, just across like the jungle or mushroom grass. I think the world re-generates an underground hallow and deep corruption after Wall of Flesh is defeated, and these are distinct areas that can't grow. Someone should try to create an artificial underground hallow to test this.

(In response to above) It IS possible to create artificial underground hallow and corruption. The game determines if it's hallow/corruption based on the number of those biome-specific blocks, not if there's actually supposed to hallow/corruption there. As for the fact that Hallow/Corruption don't spread downward from the surface, how would they? There's not enough area they can spread to to move downward. There's not enough stone or exposed dirt for that to happen. --Henix

Spreading tests
Add your remarks/results here !

Okay, I just tested planting some Hallowed Seeds in a not-hardmode world. Here is what I noticed : Yeah, I know that pre-hardmode artificial Hallow isn't very interesting, but that's for the sake of science. --Tcas 23:02, 3 December 2011 (UTC)
 * the artificial Hallow spreads exactly like the Corruption (pre-hardmode) :
 * only on dirt blocks, overrides normal grass;
 * does not spread through sand, stone, clay and mud;
 * if there is enough Hallow, the background and music change.
 * However, since all Hallow mobs were introduced as hardmode, only the usual mobs (slimes, zombies) spawn.
 * Since stone is not affected, no Underground Hallow biome is created
 * Hallowed does stop at Corruption and Corruption stops at Hallowed,they cannot spread over each other.
 * Not tested :
 * Spreading speed : is it the same as for the Corruption ? Is it slower than in hardmode ?

Spread distance
After some testing it seems "hallow blocks" can turn blocks up to 3 blocks away into hallowed blocks.

I have tested recently the hallow + Corruption blocks, I noticed on normal terraria (Not hard mode) That the hallow pushed into some corruption,this only seemed to happen though when there was more of the hallow in the area.

Removal
Corruption can be removed with Purification Powder; what about Hallow? - Spinfx 01:59, 15 December 2011 (UTC)
 * Vile powder has the same effect on the Hallow --GauHelldragon 03:51, 15 December 2011 (UTC)
