Can You Fight the Brain of Cthulhu in a Corruption World?
The short answer is: Yes, you can fight the Brain of Cthulhu in a Corruption world, but it requires some extra effort. While the Brain of Cthulhu is naturally associated with the Crimson biome, and the Eater of Worlds is the boss typically found in the Corruption biome, it is still very much possible to face the Brain of Cthulhu even if your world spawned with Corruption. You will, however, need to create a Crimson biome artificially within your Corruption world to do so.
Summoning the Brain of Cthulhu: The Crimson Connection
The Brain of Cthulhu is a pre-Hardmode boss, and its summoning is directly linked to the Crimson biome. Normally, in a Crimson world, you can summon this fleshy foe in one of two ways:
- Destroying three Crimson Hearts: Deep within the Crimson biome, you’ll find Crimson Hearts, floating, pulsating, red, heart-shaped background objects. Breaking three of these with a hammer or explosives will summon the Brain of Cthulhu.
- Using a Bloody Spine: This is a boss-summoning item crafted with 30 Vicious Powder and 15 Vertebra. Using a Bloody Spine within the Crimson or Underground Crimson biome will also summon the Brain of Cthulhu.
However, a world that spawns with Corruption lacks both the Crimson Hearts and the Crimson biome, making a straightforward summoning impossible.
Bridging the Biome Gap: Creating an Artificial Crimson
Since the Bloody Spine alone cannot be used to summon the Brain of Cthulhu in a corruption world, creating an artificial crimson biome becomes necessary. Here’s how you can create a crimson area within your corruption world:
- Crimson Seeds or Blocks: The most common way is using Crimson Seeds or crimson-related blocks. Crimson Seeds, when used on suitable blocks such as dirt or stone, convert the area into the Crimson biome. You can acquire these from a world that has Crimson. You can obtain Crimstone Blocks from the Crimson biome on another world as well. Placing a fair amount of Crimstone Blocks or spreading Crimson grass via seeds will begin to create a Crimson Biome in your Corruption world.
- Crimson Grass: You’ll need to ensure that the Crimson grass spreads sufficiently. The game recognizes the biome based on the prevalence of specific blocks and grass types. Start with a small area and ensure it grows outward to encompass a reasonable fighting zone.
- Underground Crimson: Ideally, for the Brain of Cthulhu, create a large area underground so that the game will recognize it as an Underground Crimson Biome. This will also help stop the Brain of Cthulhu from enraging.
- Crimson Hearts: You can use the Crimson Hearts you acquired in the Crimson world you got the seeds from to set the stage for an easier summoning experience.
Once a crimson biome has been established, you can summon the Brain of Cthulhu in two ways again:
- Breaking three Crimson Hearts: Place and break the crimson hearts you obtained on another world.
- Using a Bloody Spine: Simply use a Bloody Spine within the boundaries of your newly created Crimson Biome.
Fighting the Brain of Cthulhu: Tactics and Considerations
Whether you are in a crimson world or a corruption world that has an artificially created crimson biome, the Brain of Cthulhu fight remains consistent. The boss itself is a large, flying brain with two phases, surrounded by several smaller enemies called Creepers.
- First Phase: The Brain is invulnerable in its first phase. Your focus should be on destroying the surrounding Creepers, as they will die in one hit.
- Second Phase: Once all the Creepers are dead, the Brain will reveal itself and begin attacking you directly. Be prepared for its erratic movements and attacks.
- Knockback: Unlike all other bosses, the Brain of Cthulhu is affected by knockback. Using weapons with high knockback can be highly advantageous.
- Debuffs: In Expert mode, the Brain of Cthulhu can inflict random debuffs like Slow or Bleeding, making the fight much more challenging.
- Enraged: If you leave the Crimson biome with the Brain of Cthulhu in tow, it will become enraged and much faster. Fighting the boss in the Underground Crimson Biome is advised.
Successfully defeating the Brain of Cthulhu grants you valuable resources like Tissue Samples and Crimtane Ore, which are crucial for crafting powerful gear.
