The Crimson

"Making the world bloody..."

The Crimson is a hazardous surface biome that presents a gore theme, in contrast to the Corruption's diseased wasteland theme. A generated world will contain one of the two, chosen at random during world creation, each with a 50% chance of occurring. If chosen, it generally will be located far from a player's original spawn point. The two contain similar hazards, though the Crimson is often considered by players to be the more difficult of the two. Each have their own unique respective enemies, items, and blocks. The tools, weapons and armor obtained via Crimson materials have minor advantages over those obtained via Corruption materials. New players should avoid The Crimson before obtaining better gear.

As with the Corruption, the Crimson contains multiple Chasms, deep pits in the ground that lead to underground tunnels. Unlike the Corruption's vertical drops, the chasms in the Crimson cut at angles into the terrain, lead to large circular cavities, then branch off into smaller veins that lead to Crimson Hearts. Crimson Hearts are the Crimson counterpart to the Corruption's Shadow Orbs, and can be destroyed to achieve various effects that advance gameplay (see Crimson Heart for details).

Crimtane Ore can be collected in order to craft various advanced items, like the Corruption's Demonite Ore. Crimson Altars are found underground, which primarily come into play once a world enters Hardmode, though they also function as Crafting Stations for a few items; these operate identically to the Corruption's Demon Altars.

The Brain of Cthulhu is a Boss that can be encountered in the Crimson, and is the Crimson counterpart to the Corruption's Eater of Worlds; though it is slightly more difficult to defeat.

Crimson spreads in the same manner as Corruption, replacing Grass with Crimson grass, and in Hardmode, replacing Sand with Crimsand, Stone Blocks with Crimstone, Ice Blocks with Red Ice Blocks and the Underground Crimson is formed.

NOTE : View Underground Crimson for the mobs that spawn during Hardmode in and under the cavern layer.

Tips

 * The step in world generation in which the Crimson is created is called "Making the world bloody." If you want a Crimson world, look for that step during creation.
 * Another way to know if your world has Crimson is to ask the Guide. He will tell you to break a Crimson Heart if your world has Crimson, or to break a Shadow Orb if the world has Corruption.
 * In the PC version, a progress bar is shown while creating a world. Its frame will be green and purple if the world is to contain Corruption, or green and red if it is to contain Crimson.
 * Even after world creation you can check if the world is crimson or corruption by checking the color of the tree icon (purple = corrupt, red = crimson) in the world selection screen.
 * In Expert Mode, it is advised to have access to a Crimson biome because you can possibly get the Vampire Knives, which help tremendously.
