Snow biome

See also: Underground Snow

A Snow biome is an area dominated by Snow Blocks and Ice Blocks, and displays a constant snowfall effect. Trees within Snow biomes have a snowy cover on them, and yield Boreal Wood, instead of ordinary Wood (Pc only.png PC version only). During rain, a Snow biome displays a blizzard instead, where snowfall increases and unique enemies spawn.

Dome shaped hills are commonly found in snow biomes, each one containing a cave that is similar in generation to Crimson Chasms.

Some NPCs will sell different items when situated in a snow biome, including the Merchant, Painter, and Clothier.

At Cavern depths, each Snow biome becomes an Underground Snow biome.

  • Player-created Snow biomes are possible by placing Snow Blocks and/or Ice Blocks in an area.
  • Water does not turn into ice blocks in a Snow biome. Ice blocks are generated only on world creation.
  • Snow biomes are somewhat immune to surface Hallow and Corruption/Crimson spread, since snow blocks cannot be transformed. However, Ice Blocks are affected and will be transformed into Pink Ice Blocks (Hallow), Purple Ice Blocks (Corruption) and Red Ice Blocks (Crimson), which mostly affects the Underground Snow.
  • Grass will not grow on Dirt Blocks in a Snow biome.
  • From surface to underground, the snow biome will always generate in a shape similar to a trapezoid.
  • The Snow biome will always be located on the opposite side of the world as the Jungle. However, unlike the Jungle, it can be located very close to spawn.
  • On the Mobile version, the Snow biome (And underground snow) will only be present in about 1 in 3 worlds.
