Stats / Weaknesses:

Brain of Cthulhu (First & Second Form): HP: 1,000/1,700 (effective HP: 3000-4000/5100-6800), Damage: 30/54, Defense: 14
Creeper Minions: HP: 100/170, Damage: 20/36, Defense: 10
The Brain's effective HP is higher due to the need to defeat its numerous Creeper minions first.

Phases:

First Form: The Brain teleports periodically, and its Creeper minions move to its new location, dealing contact damage.
Second Form: Triggered when all Creepers are defeated. The Brain teleports rapidly and charges the player, often appearing directly on top of them. In Expert mode, it summons three mirror images of itself that become more opaque as its HP decreases; the true Brain can be identified by its minimap icon.

Strategy:

Focus on defeating the Creeper minions first to expose the Brain of Cthulhu.
Be prepared for rapid teleportation and charges in the second form.
In Expert mode, pay close attention to the minimap to distinguish the true Brain from its mirror images.
In Expert mode, be aware that both the Brain and Creepers can inflict random debuffs (Poisoned, Darkness, Cursed, Bleeding, Confused, Slow, Weak, Silenced, Broken Armor). Creepers always inflict one, while the Brain has a 33% chance.

Drops:

Normal Mode: Coins (5g), Brain of Cthulhu Trophy (10%), Crimtane Ore (40-90, 100%), Lesser Healing Potions (5-15, 100%), Tissue Sample (30-50, 100%), Bone Rattle (5%)
Expert Mode: Coins (12g 50s), Brain of Confusion (100%)
