Ice biome



The Ice biome, also known as the Underground Tundra or Underground Snow biome, is a biome that is the underground version of the Snow biome, starting at the Cavern layer and stopping at the lava layer. On the, the Ice biome starts at the Underground layer. It is composed mainly of Snow Blocks and Ice Blocks. Thin Ice can be found generated over water and breaks when a character falls over 4 tiles onto it (unless using the Ice Skates or another accessory crafted from them). The Ice biome is the only place where Frozen Chests ( Ice Chests) can be found naturally.

In Hardmode, the Corruption, Crimson, and Hallow can spread through it, generating Purple, Red, and Pink Ice Blocks respectively. They are unable to spread through Snow Blocks.

On the, normal-sized worlds only have a 1/3 chance of containing a snow biome, and their respective underground. Furthermore, Armored Vikings, Snow Flinx, Icy Mermen, Ice Tortoises and Ice Mimics will spawn much more rarely than on the.

Trivia

 * It seems as if the Ice biome can actually go all the way down to the top of the Underworld layer if one were to create artificial ice biomes in the lava layer. If someone were to place the required amount of blocks in the area, regardless if it's in the lava layers or not, the music will still play, its background will show, and its enemies will spawn as normal. However, its background is changed to the default caverns background while retaining its music when entering the pre-underworld layer (the layer with the pre-underworld backgrounds), similar to how the Underground Corruption, Crimson, or Hallow biomes revert to the default background just before the underworld.
