Terraria Overhaul/Brain of Cthulhu

The Brain of Cthulhu is a Pre-Hardmode Crimson themed Boss. It spawns when players destroy 3 Crimson Hearts in a Crimson world, or when a player uses a Bloody Spine anywhere in a Crimson biome.

Gameplay

 * Every contact with The Brain of Cthulhu now gives Confused debuff for 1 second.
 * The Brain of Cthulhu will now constantly create new Creepers in its second phase.

Visuals & Audio

 * Players will hear loud horrifying screams with every smashed Crimson Heart.
 * During the fight, the Brain of Cthulhu emits distorted sounds, likely speech.
 * This speech is a lower pitched and differently cut version of the Icon of Sin's speech in Doom II.

Death Animation

 * The Brain starts teleporting to random players and shaking rapidly and aggressively, while chaotically talking and screaming. It disappears for a few seconds before teleporting back to its original death position in a violent gore explosion, already dead.

Trivia

 * Like all Overhaul bosses with death animations, the Brain of Cthulhu uses its vanilla gore sprites, resulting in nonsensical scenes with piles of the brain's hearts and large chunks of the brain scattered on the floor.
