The Hallow is a new biome that is created once you have defeated the Wall of Flesh in the Underworld. It is an anti-Corruption biome and can be spread by planting Hallowed Seeds or throwing Holy Water and is most effective when used to counter the spreading of Corruption. However the corruption and hallow can spread over each other still, just very slowly.

The biome has light blue grass and colored trees, and the background has a big rainbow. It is home to Unicorns, Pixies, and Gastropods. (Only at night will the Gastropods spawn)

The Hallow has its own underground level, the Underground Hallow, primarily made of Pearlstone, a white colored Ebonstone-like block converted from normal stone. Much like Ebonstone, Pearlstone takes longer to dig than normal stone. To dig Pearlstone, you need at least a Nightmare Pickaxe, which is made from Demonite Ore and Demon Scale (both dropped by Eater of Worlds.

The Dryad can say what the percentage of Hallow and Corruption is in the world, once the Wall of Flesh has been defeated. The Hallow can spread both on the surface and Underground.

Purification Powder has no effect on the hallowed ground; However, Vile Powder can return hallowed ground to the default biome of the world.

The Hallow can provide a challenge to players unprepared so it is recommended that you at least have Cobalt Armor

SpreadingEdit

The Hallow can be spread above ground with Pearlstone Blocks, Pearlsand, Holy Water, or with Hallowed Seeds.

The rules for spreading The Hallow are as follows:

• Pearlstone and Pearlsand Blocks will spread The Hallow to adjacent Stone, Sand, and Grass blocks (Pearlstone will not spread The Hallow to dirt blocks without Grass growing on them).
• When planted, Hallowed Seeds will spread The Hallow to adjacent Dirt, Stone, Sand, and Grass blocks.
• The Hallow cannot spread to Mud Blocks ; therefore, the Hallow cannot spread through the jungle.
• The hallow also cannot spread to Snow Blocks ; therefore the Hallow cannot spread through Snow Biome.
• Sunflowers will not impede the spreading of The Hallow.
• Hallow will not spread through gaps in the environment that are three or more blocks across.
• Hallow will not spread through synthetic blocks (i.e. materials such as Gray Brick ) that are three or more blocks across.
• Vines growing from hallowed ground can spread The Hallow through proximity.
• The Hallow can be planted in a world where the Wall of Flesh has not been killed but it won't spread through Sand and Stone. It will spread the hallow grass over default grass, however. If the Hallow is created underground, Chaos Elementals can spawn, but neither they nor any other monsters will drop Souls upon death. Crystal Shards also won't grow in pre-WoF world.

NotesEdit

• While The Hallow does prevent Corruption from spreading, the creatures spawned within are still on-par with other post-Wall of Flesh content.
• If you want to get rid of the Corruption (after beating the Wall of Flesh of course) an easy way would be to spread the hallow there with hallow seeds, some holy water or by placing different Hallow blocks.
• You can use Holy Water in a world where there is no hallow, and it spawns it, though it is slower.
• If you failed to stop The Corruption post Wall of Flesh, spreading The Hallow is a quick alternative of safe housing for your NPCs from the quickly spreading biome. As opposed to The Corruption, NPCs will not move out of rooms 'infected' by The Hallow, and monsters that spawn in this biome do not have the ability of full flight, (the exception maybe the Gastropod) so you can safely build an elevated house without the worry of creatures attacking your NPCs.
• The absolute best way to stay free from both Corruption and Hallow is to build your house in a snow biome. Snow blocks are immune to both hallow or corruption, and no post-hardmode monsters spawn on the surface of a snow biome. This method however, only applies to surface, not the underground, and it does not prevent stone and grass blocks under your house from getting hallowed or corrupted.

TriviaEdit

• The Hallow shows some resemblance to the Forest in "The Lorax" by Dr. Seuss.
