Crimson converted by the Hallow upon start of Hardmode.

"Hallowed" redirects here. For the bars, see Hallowed Bar.

Once you enter hallowed land, you will see a rainbow in the sky. I can help you with painting that if you want.

— The Painter

The Hallow is a Hardmode surface biome. It is characterized by pastel-colored fairytale graphics, with cyan-colored grass, multicolored trees, and a large rainbow in the background, as well as similarly whimsical-looking (though dangerous) enemies. The Underground Hallow biome can be found directly beneath a naturally-generated Hallow biome.

The Hallow does not exist in newly-generated worlds. It is generated along with a large Underground Hallow biome when the Wall of Flesh is defeated for the first time and the world converts to Hardmode. This initial conversion can replace preexisting sections of the world's "evil biome" (Corruption or Crimson). If areas of Jungle or Glowing Mushroom biome are included in the conversion area, stone will be converted but the (mud based) grasses will be unaffected.

Once generated, Hallow spreads in a manner similar to the evil biomes; Pearlstone, Pearlsand, and dirt blocks growing Hallowed grass will spread Hallow to neighboring blocks, causing Hallow enemies to spawn over ever-larger areas. Hallow can also be seeded in new areas via Hallowed Seeds, Holy Water, or Blue Solution. See below or the Biome spread page for more details.

The Hallow, unlike Crimson and Corruption, cannot spread through mud areas such as found in Jungles or Glowing Mushroom biomes.

The Dryad can tell the player the percentage of Hallow and Corruption/Crimson in the world.

Main article: Biome spread

The Hallow spreads itself, similar to the evil biomes. This means that it slowly converts certain susceptible tiles that are in the vicinity of existing Hallowed blocks. Defeating Plantera for the first time reduces the speed of the Hallow's spread by 50*1/2 (50%). Hallow can convert Crimson and Corruption into grass blocks, but otherwise cannot convert blocks already claimed by an evil biome. This can result in areas where the Hallow and an evil biome intertwine closely. If Hallow is introduced into a pre-Hardmode world, its spread will be very limited, similarly to the evil biomes.

Hallowed Desert[]

The Hallowed Desert.

When the Hallow spreads through desert, it becomes Hallowed Desert. It is very similar to the Hallow: the music theme is the same, the enemies are the same (except for the Light Mummy and Crystal Thresher), and the background is slightly different.

The sand is replaced by pearlsand. Although their color is different, cacti still drop cactus when cut, and waterleaf plants are also able to grow.

  • An artificial Hallow biome requires at least 125 Hallowed blocks, such as Hallowed grass, Pearlstone, Pearlsand, or Pink Ice.
  • In Hardmode, all enemies in the Hallow have a chance of dropping a Hallowed Key.
  • Making an artificial Hallow biome in a pre-Hardmode world (for example via Blue Solution) will change the background and music, though no Hallow enemies will spawn.
    • However, oddly, Lightning Bugs will still spawn during night.
  • The Corruption or Crimson is unable to overlap the Hallow.
  • The Hallow can spread to Grass and Flower Walls.
  • The Hallow will sometimes not spawn on the Surface; only underground.
  • Based on the source code, the Dryad considers the Hallow to be "good", as opposed to the Corruption or Crimson, which she considers "bad." However, she does not consider the world to be "pure" until all three are eradicated.
  • Again, on beginning Hardmode the Hallow can overlay the Jungle, and this will convert stone but not Jungle grass. Due to the Jungle being mostly Mud, this can lead to there not being enough Hallow blocks present to consistently spawn the biome's enemies. However, the Pearlstone present can still produce small fragments of Hallow biome, which can show pink water and enrage Plantera.

  • The Hallow does not have an alternate version, unlike the Corruption (which is the Crimson). Originally, a candy-land themed alternate for the Hallow was planned,[1] but the idea was scrapped before development.
  • The verb to hallow means to make holy, indicating that the name Hallow likely means holy land.
  • Hallowed grass will spawn on floating islands in the 10 year anniversary seed, at world generation allowing for the creation of a hallow biome pre-hard mode.
  • Official Terraria Lore – According to the official game lore, the Hallow is created once the world's guardian (the Wall of Flesh) is defeated. It is complete, extreme purity that serves to cure threats that attempt to disrupt the natural balance of good and evil.
