Crimson



The Crimson biome is introduced in 1.2, being an alternative to the Corruption and chosen at world generation. The Crimson biome cannot co-exist with the Corruption in the same world. When the world generator generates the Crimson, any Sand that is within the biome is converted to Crimsand. As with the Corruption, the Crimson has multiple chasms, however, they are in varying angles and not a vertical drop.

Also, the Crimson replaces the Shadow Orbs which spawn in the Corruption with Demon Hearts. Crimtane Ore and Crimson Altars replace the Corruption's Demonite Ore and Demon Altar respectively. The Crimson Altar functions the same as a Demon Altar, with only difference being the visual graphics. The Brain of Cthulhu is the Crimson version of the Eater of Worlds, being slightly more difficult. The tools, weapons and armor from the Crimson have minor stat boosts, in exchange for the Crimson's difficulty.

The Crimson can also be converted from any other biome using the Clentaminator with the Red Solution, only obtainable when the Steampunker is living this biome. During Hardmode, the spread of Crimson is the exact same as the Corruption; replacing Grass with Crimson Grass, and Sand with Crimsand.

Should the crimson overlap with the Snow Biome during world generation, it replaces Ice Blocks with Red Ice Blocks, along with Snow into Red Snow.
