"Making the world bloody..."

The Crimson is a hazardous surface biome that presents a 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 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 due to its 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.

Notes[edit | edit source]

  • The Steampunker will only sell the Flesh Cloning Vat in a world that generated with Crimson naturally. Artificially creating a Crimson biome will not cause her to sell it.
  • Sand within Crimson becomes Crimsand. Ice Blocks become Red Ice Blocks.
  • Crimson can be spread artificially using the Clentaminator with the Red Solution, obtainable from the Steampunker during a Blood Moon in Crimson worlds (she sells the Purple Solution in a Corruption world instead).
  • Trees in the Crimson do not drop Acorns.
  • Creating a new Crimson biome requires at least 200 Crimson blocks, such as Dirt with Crimson grass, Crimstone, Crimsand or Red Ice Blocks. Although Crimson replaces Corruption at world generation, it does not prevent Corruption from being artificially created in a Crimson world, and vice versa. Spreading remains normal.
  • In order to stop the spread of Crimson in Hardmode, the player must create a gap of at least three tiles containing empty space or non-corruptible blocks. Hallow blocks will also stop the spread of Crimson, but will spawn its own hazards as well.

Tips[edit | edit source]

  • 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.
