Grenades and other splash damage weapons can kill the Creepers very quickly, as they will bunch up often.
Weapons that inflict these debuffs can make quick work of them.
Creepers have low individual health and are especially susceptible to the On Fire! and Frostburn debuffs.
Since Hellstone can be destroyed with explosives in Hardmode, and Hardmode ores can be obtained from fishing, defeating the Brain of Cthulhu is not necessary to obtaining those items.įor more elaborate strategies on defeating Brain of Cthulhu, including weapon and arena recommendations, see Guide:Brain of Cthulhu strategies.
Crafting the Deathbringer Pickaxe (from Tissue Samples and Crimtane Ore) will not be necessary if the player obtains the Reaver Shark (through fishing).
However, defeating the Brain of Cthulhu is the only way to gain access to the Tavernkeep and, as of 1.4.0.2, Meteorites.
Note that actually defeating the Brain of Cthulhu is not completely necessary to progress, as the Creepers may drop the needed amount of materials.
They seem to share their Creepers and go into their second phases simultaneously.
Two Brains can be summoned at once by smashing Crimson Hearts.
If the player leaves the Crimson, the Brain of Cthulhu will despawn.
Creepers are more aggressive in Expert Mode and Master Mode.
Creepers drop Hearts at a higher rate than most enemies.
The debuffs inflicted by the Brain and the Creepers are extended in duration, as detailed in the table above.
This brings the boss's overall health up from 5100 health to 6487 health.
The Creepers gain a health increase of the same percentage, going from 170 health up to 216 health.
This brings its original Expert Mode health of 1700 health up to 2167 health.
In Master Mode, the Brain of Cthulhu gains a 27.47% health increase.
The probabilities of applying each debuff are listed in the following table note that the Creepers always inflict a debuff while the Brain only has a 33.33*1/3 (33.33%) chance to do so.
Furthermore, both the Creepers (in the first phase) and the Brain (in the second phase) inflict a random debuff upon contact.
In Expert mode, the second phase now has three mirror images of the Brain appear around the player, mirroring the Brain's movements and becoming more opaque as the boss loses health.
This brings the boss's overall health up from 3000 health to 5100 health.
The Creepers gain a health increase of the same percentage, going from 100 health up to 170 health.
This brings its original Classic Mode health of 1000 health up to 1700 health.
In Expert mode, the Brain of Cthulhu gains a 70% health increase.
In the second phase, the Brain becomes vulnerable to attacks and knockback and it aggressively attempts to ram the player while rapidly teleporting around. Once all Creepers are defeated, the Brain enters its second phase. The Creepers do not teleport along with the Brain but are instead pulled between the player and the Brain in large, sweeping orbits, forming groups and allowing the player to deal damage to all the Creepers at the same time. It teleports around the player, drawing nearer before teleporting away again in a random direction while its Creeper minions attack the player. The Brain itself is initially invincible. When Otherworldly music is enabled, the track Boss 1 (Otherworldly) (Otherworldly).mp3 will play instead. While the Brain of Cthulhu is alive, the music Boss 3 will play. Unlike its Corruption counterpart, it does not have a mechanical equivalent in Hardmode. The Brain of Cthulhu is the Crimson counterpart to the Eater of Worlds. Defeating the Brain of Cthulhu for the first time allows the Tavernkeep NPC to spawn. All Creepers must be destroyed first before the Brain of Cthulhu enters its second phase, where it becomes vulnerable to attack and can be killed.ĭefeating the Brain of Cthulhu and its attendant Creepers is the only way to obtain Tissue Samples, and is one of the ways to obtain usable quantities of Crimtane Ore. Creepers do not respawn once they are killed. 20 Creepers spawn along with the Brain and orbit the boss at high speed. In the first, the Brain is invulnerable and teleports randomly around the player. It can be summoned when 3 Crimson Hearts are destroyed in a Crimson world, or when a player uses a Bloody Spine anywhere in the Crimson or Underground Crimson biome. The Brain of Cthulhu is a pre-Hardmode, Crimson-themed boss resembling a large, flying brain. For the Old-gen console and 3DS pet summon, see Brain.
