Ice biome



The Underground Snow is a biome, and is the underground version of the Snow biome, starting at the Cavern layer and stopping at the lava layer. On the, the Underground Snow 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 Underground Snow biome is the only place where 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.
