"A horrible chill goes down your spine..." "Screams echo around you..."

The Brain of Cthulhu is a Boss that spawns in the Crimson biome. It appears every time a player shatters three Crimson Hearts. It can also be summoned using a Bloody Spine.

The Brain of Cthulhu is the Crimson counterpart to the Corruption's Eater of Worlds. In a world containing Crimson, only the Brain of Cthulhu, and not the Eater of Worlds, will be summonable unless enough corruption is imported and Worm Food is used.

Attacks[edit]

First phase[edit]

The Brain is invincible and teleports around the area. It is surrounded by eyes called Creepers that attempt to deal damage by flying into the player. Each Creeper has its own health bar, and will drop Tissue Samples, Crimtane Ore, hearts, and stars. When all the Creepers are destroyed, the Brain itself becomes vulnerable and can take damage normally.

Second phase[edit]

The Brain will now teleport more frantically with no Creeper eyes to defend it. It concentrates more on ramming the player, and moves faster.

Tips[edit]

Trivia[edit]

  • The Brain of Cthulhu, along with the Eye of Cthulhu, is based on the character Cthulhu from the works of the author H.P. Lovecraft.
  • The Brain of Cthulhu strongly resembles the boss Phantoon from the game Super Metroid, both in appearance and behavior.
  • The Brain of Cthulhu's second form appears to have a heart inside of it, as well as an eye in the heart.
  • The Brain of Cthulhu is the only boss susceptible to knockback.
  • Unlike the Eater of Worlds, the Brain of Cthulhu doesn't run away if you leave the Crimson.
  • Unlike the Eater of Worlds, the Eye of Cthulhu, and Skeletron, the Brain of Cthulhu does not have a respective Hardmode boss on PC, but Ocarm may be it's counterpart for the console/mobile. (The others having The Destroyer, The Twins and Skeletron Prime respectively.)
  • The Brain of Cthulhu has the least HP out of all the bosses, with even less than the Eye of Cthulhu in its second form. However, if counting the health of its creepers, it has more health than King Slime.
  • Like some other monsters, the Brain will continue to attack a newly dead player's grave, almost as a sign of disrespect.

Bugs[edit]

Anomaly.png Anomaly 1.2.2 : The Brain can not only follow you if you leave crimson, but can also be spawned in any biome by destroying 3 Crimson Hearts, not only in crimson
Anomaly.png Anomaly 1.2.0.3.1: If two or more Brains are summoned at once, no Brain will go into its second stage until all Brains have lost all their Creepers.
Bug.png Bug 1.2.0.3.1: If you die fairly close to your spawn the Brain of Cthulhu can follow you to your spawn due to the lack of distance between your spawn and the Brain of Cthulhu, preventing it from despawning.
Bug.png Bug 1.2.3: Killing the Creepers as the brain is taking damage will cause the brain to disappear, The Crimson Rod was seen to not do this but will need further testing.
