This article is about the hardmode biome. For the armor tier, see Hallowed armor.
See also: Underground Hallow

The Hallow is a Hardmode surface biome. It has an easily recognizable cyan-colored grass, multicolored trees, and a huge rainbow in the background. It is the only biome where you'll find Unicorns, Pixies and Gastropods. The Underground Hallow biome can be found directly under a naturally-generated Hallow biome.

Hallow does not exist in a newly-generated world. Instead, it is generated along with a large Underground Hallow biome when the Wall of Flesh is defeated the first time. The Hallow can also be artificially created by planting Hallowed Seeds in dirt, using Holy Water or Blue Solution, or placing Pearlstone and Pearlsand blocks.

The Hallow is the only environment through which the Corruption and Crimson cannot spread at all. Consequently, its role is very important in hardmode, where the corruption becomes nearly unstoppable. The Dryad will tell the player the percentage of Hallow and Corruption/Crimson in the world. Neither the Hallow, Corruption nor Crimson can spread through the Underworld, but the wall of flesh causes some of it to be biome related. The Hallow cannot spread through mud biomes like Jungles or Glowing Mushroom biomes as well.

Although activating hardmode requires the player to have good equipment, the Hallow is a challenging biome, especially at night, since it is home to powerful mobs. Do not be fooled by the cute and childish scenery.

[edit] Spreading

The initial Hallow spread during the onset of Hardmode may "purge" pre-Hardmode Corruption/Crimson areas.

[edit] Hardmode

As soon as Wall of Flesh is defeated, a section of Hallow spawns. This strip goes from the Underworld to the surface, converting stone, sand and grass in its path into pearlstone, pearlsand and hallowed grass, respectively. This does include floating islands that happen to be in the path of this stripe. The Hallow's stripe can intersect with the Corruption's chasms as well as Floating Islands.

Hallow spreads in a manner very similar to corruption:

There are also a few differences in the way that the Hallow spreads:

  • The Hallow can spread through its vines (but can not "go up" through regular vines).
  • The Hallow does not uproot sunflowers, but can still spread beneath them.
  • Pearlstone does not seem to create hallowed grass as fast as ebonstone creates corrupt grass.
  • The Hallow cannot convert mud or jungle grass. This means the Hallow can be completely superseded by the Jungle causing no blocks to become Hallow.

Killing Plantera slows the spread of Corruption/Crimson/Hallow to 1/3 speed.

[edit] Pre-hardmode

Hallow does not normally exist before the world enters hardmode, but can be created with Hallowed Seeds, Holy Water, or the Blue Solution (for use with the Clentaminator) imported from another world. If it is created, it will only spread the same way as pre-hardmode Corruption: slowly, on the surface, and only through dirt and grass. This means you can safely use other hallowed blocks without creating a biome and converting regular blocks in pre-hardmode worlds. It still prevents the Corruption from spreading. Furthermore, Hallow-specific mobs will not appear, since they were only designed for hardmode.

[edit] Notes

  • One way to protect yourself and your NPCs is by building a Sky City. As Wraiths can pass through blocks but they cannot fly upward.
  • An artificial Hallow biome requires at least 100 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 Mold.
  • The Hallow seems to be the only important biome that does not have a boss, which makes one wonder if there will be one in a future update.
  • The Hallow doesn't have an altenate version, unlike the Corruption(Which is the Crimson).
Anomaly.png Anomaly: Several players reported no growth of the Hallow with Hallowed Seeds in the ground in pre-hardmode.
Anomaly.png Anomaly: Hallow has been seen to "purify" the Corruption.
Anomaly.png Anomaly: Occasionally, no hallow will spawn when hardmode is activated.
Bug.png Bug : Hallow Music sometimes plays in the background quietly and loops making players have to exit and re-enter the game.
Bug.png Bug : Rarely, The Hallow is generated on worldgen rather than when hardmode is activated.
Bug.png Bug : Sometimes (mainly if the hallow is generated in the ice biome) there will be no grass meaning surface mobs will not spawn. The only way to fix this is by buying seeds from your Dryad.

[edit] 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 mobs are the same (except for the Light Mummy), and the background is slightly different.

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

[edit] History

  • 1.2.0.3: Hardmode Crimson, Corruption, and Hallow spread is now slowed after killing Plantera instead of any Mechanical Boss.
  • 1.1: Introduced.
