The Crimson



The Crimson is a hazardous surface biome that presents a red gore theme. It may exist somewhere in a generated world, generally far from a player's original spawn point. It is the counterpart to the Corruption biome's diseased wasteland theme. A generated world will contain only one of the two, chosen at random during world creation, each with a 50% chance of occurring. The two contain similar hazards, though the Crimson is often considered by players to be the more difficult of the two. Each has 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 due to it's difficulties.

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, and the Underground Crimson is formed.

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

Trivia

 * While normal mode Crimson enemies are based on blood (Blood Crawler, Face Monster), Crimson hardmode enemies seem to be based on pus (Floaty Gross, Ichor Sticker).
 * What exactly the giant skeletal remains seen in the background are is unknown, though could possibly be the remains of Cthulhu.
 * The Crimson may be a reference to the War of the Worlds's (1898) red weed, which was brought to earth by the Martians. The trees in the background and the structures from the film have the same stringing flesh.
 * The chasms that make up the Crimson, when viewed from the map, occasionally appear in the form of long twisting arms ending in hands, neurons ending in dendrites, or veins, or can possibly interpreted as a womb.
 * Due to the game containing various enemies related to Cthulhu, the first boss released exclusively for this area being one of them, and the fact that you can use Crimstone to get Flesh Blocks, one could assume this biome is made of the body parts, remains, or even blood of Cthulhu.
