"Making the world bloody..."
The Crimson is an evil biome with a red gore theme, in contrast to the dark purple wasteland theme of its counterpart, the Corruption. Every world will contain one of the two, generated randomly (each with a 50% chance of occurring) or chosen by the player upon world creation. Both contain similar hazards and feature their own unique enemies, items, and blocks. The tools, weapons, and armor obtained via Crimson materials generally have minor advantages over those obtained via Corruption materials. Crimson enemies tend to have slightly higher stats, such as health, defense, and damage.
The Crimson contains multiple chasms, extensions of the biome into the underground. Every chasm has an entrance on the surface and leads to a large, circular cavity, then branches off into small "fingers" which end with a Crimson Heart. Crimson Altars generally line the chasm's passages, appearing inside and around it. Chasms consist of Crimstone, which can be blown up by explosives or mined with a Nightmare/Deathbringer Pickaxe or higher.
The Crimson spreads, meaning it slowly converts adjacent tiles to their Crimson variants. See below for details. Chasms, Crimson Altars, and Crimson Hearts will only appear upon world generation, and will not spawn in a Crimson area that has formed through spreading. If enough Crimson manages to take over a new area, then that area will eventually adopt the Crimson's theme music, background, and water color. For an area to be considered a Crimson biome, at least 200 tiles of Crimson grass or Crimson blocks must be present.

Spread[edit | edit source]
In Pre-Hardmode, the Crimson can spread, but only under limited conditions:
- Crimson grass can spread in a manner similar to normal grass, converting adjacent Dirt Blocks with at least one side open to air (only in the surface layer).
- Crimson grass can also displace normal grass, unless the grass has a Sunflower planted on it.
- Crimson grass may sprout thorny bushes, which can spread Crimson grass adhering to the same rules.
Naturally-occurring Crimson will often be halted by various natural barriers (stone, Desert, etc.) before it is even discovered, but when creating an artificial Crimson in Pre-Hardmode, care should be taken that it does not spread further than intended.
|Original Tile||Converted Tile|
|Jungle thorny bushes||Crimson thorny bushes|
Blocks which are up to three tiles away from an existing Crimson block can be converted, even if incorruptible blocks are in the way. Grass and thorny bushes can spread to tiles which are up to five tiles away. Due to this change, Sunflowers can no longer stop the spread.
Crimson vines can spread the Crimson as well.
The Crimson does not spread through any other materials, even natural materials like Clay and Snow. Therefore, in order to halt the spread, a gap or barrier, consisting of any incorruptible block, of three tiles is necessary. Note that thorny bushes might bridge a gap and continue the spread.
Defeating Plantera reduces the speed of the Crimson's spread to 33% of the default Hardmode speed.
Crimson Desert[edit | edit source]
In Hardmode, Crimson spreads through Deserts, transforming them into Crimson Deserts. A Crimson Desert is fairly similar to a regular patch of Crimson: The theme music and enemies are the same, with the addition of Dark Mummies on the surface and Dark Lamias , Tainted Ghouls and Desert Spirits in the underground .
Notes[edit | edit source]
- Crimson can be created or spread artificially using Crimson Seeds, Vicious Powder, Blood Water, or the Clentaminator with Red Solution, obtainable from the Steampunker during a Blood Moon in Crimson worlds (she sells Purple Solution in a Corruption world instead).
- Artificially creating a new Crimson biome requires at least 200 Crimson blocks. Although Corruption might replace Crimson at world generation, it does not prevent Crimson from being artificially created in a Corruption world, and vice versa. Spreading remains normal.
- The Steampunker will only sell the Flesh Cloning Vat and Red Solution in a world that naturally generated with Crimson. Artificially creating a Crimson biome in a Corruption world will not cause her to sell these items.
- Any enemy in the Crimson or Underground Crimson has a 0.04% (1/2500) chance to drop a Crimson Key / Crimson Key Mold
- Trees in the Crimson do not drop Acorns.
Tips[edit | edit source]
For elaborate strategies on surviving in the Crimson, including detailed gear recommendations, see Guide:Surviving in the Crimson.
- Early on, determining whether a world contains Crimson is possible in the following ways:
|The tree in world selection (on the right: during Hardmode)|
- During world generation, one half of the progress bar will be green, and the other half red (purple for Corruption worlds). Additionally, the bar on the inside will be yellow (lime green for Corruption worlds), representing Ichor. The step in the world generation process in which the Crimson is created is called "Making the world bloody" ("Making the world evil" for Corruption worlds). Also, a tree at the side of the world name in the world selection has one green/normal side and one red side (purple for Corruption worlds).
- In Expert mode, the Vampire Knives (obtained from opening a Crimson Chest) are highly useful in virtually all situations. However, the Crimson's boss accessory, the Brain of Confusion, pales heavily in comparison to its Corruption counterpart, the Worm Scarf, meaning that the two balance each other out.
Trivia[edit | edit source]
- Occasionally, two chasms might overlap, causing a sort of "cross" or "X" pattern, as seen in the image to the right.
- Because of the large circular cavity, its out-warding branches, and the entrance tunnel cutting at sharp angles, the chasm could be interpreted as a cartoon-like hand, or a heart connected to veins.
- The entrance of the chasm has teeth acting like stalactites and stalagmites, and could be interpreted as the entrance being the mouth of a beast.
- The interpretations of the above mentioned trivia notes would make sense with the Crimson's gore like theme.
- Many Crimson enemies have deformed features or blisters that resemble cancerous growths. This contrasts with the rotten bodies of many Corruption enemies, sometimes with green pus dripping out of them.
- During a Blood Moon, three critters turn Crimtane (Crimtane Bunny , Crimtane Goldfish , and Vicious Penguin ), a reference to the Crimson. They can also manually be turned Crimtane with Vicious Powder.
- – According to the official game lore, the Crimson is a living being who wants to balance the world, and the creatures who come from it were once people who worshipped the Crimson.
- The shade of Crimson grass appears to be almost the exact same shade as inverted normal grass.
- The achievement "Corruptible" refers to the Corruption. However, the Crimson appears to have no Crimson achievement equivalent.
