The Crimson is a biome added in the 1.2 update of Terraria. It is the counterpart of the Corruption, and has a 50% chance to replace the Corruption in newly created worlds. It functions the same like spreading over your world. It has some new enemies, Pulsating Hearts that resemble Shadow Orb, and Crimson Altars which resemble Demon Altars.

The Crimson can be spread artificially by placing Crimstone Blocks, Red Ice Blocks, or Crimsand Blocks near corruptible blocks. The Clentaminator can also be used to spread The Crimson. 500 blocks of Crimson-related blocks are needed to create and artificial Crimson biome.

The Crimson will spread into the surface and Underground Jungle once Hard Mode is activated.

The red appearance of the biome, the flesh resembling tree leaves, the amount of insects and many gore-themed items obtained by The Crimson material suggests that the biome's theme is based heavily on decaying flesh, instead of shadow-themed Corruption.

When 3 Pulsating Hearts are broken, the third heart will spawn The Brain of Cthulhu.

The Crimson does not have chasms like the Corruption does. Instead, it contains a more web-like structure; a large circular open area that supports 4-5 branches leading to the Pulsating Hearts which can be considered the core for The Crimson biome. The caves contain Crimson Altars instead of Demon Altars, however hitting them with anything except the Pwnhammer will damage the player.

The shape of these Crimson structures look very similar to a human heart when viewed on the map.

Monsters Edit

The Crimson is a biome which can wield the dungeons 'spider cave' and spawn a variety of blood 'crawling' monsters.

The Brain of Cthulhu can be spawned after every third crimson heart in broken or by clicking on a Bloody Spine in the Crimson biome.

In Hardmode, The Crimson gets several new monsters, which are:

All the post-hardmode monsters in The Crimson have a chance of dropping a Crimson Key Mold, though this is extremely rare.

Weapons and Tools Edit

Some of these are created with Crimtane Bars, while others can be found in Crismon Hearts.

Trivia Edit

  • The Crimson looks like a heart on the map.
  • The Corruption or The Hallow will not spread into The Crimson.
  • You will know when creating a world that it will have The Crimson and not The Corruption if it says "Making the world bloody" instead of saying "Making the world evil."
  • The Meat Grinder is only dropped in Hard Mode.
