Creeper

Creepers are eyeball-like enemies that are spawned along with the Brain of Cthulhu in groups of 20. They orbit the boss at high speed, following it wherever it teleports to, acting as a shield of sorts. Creepers do not respawn once they are killed. All Creepers must be destroyed first before the Brain of Cthulhu becomes vulnerable to attacks.

Creepers have a 1/2 (50%) chance to drop a Heart if the player is below full health.

Tips

 * Creepers are susceptible to the On Fire! debuff, making weapons that inflict it a good choice for.
 * Creepers do not drop souls, Biome Keys, or.

Trivia

 * In Classic Mode, the Brain of Cthulhu does not drop any Tissue Samples itself; only Creepers do. However, both enemies drop Crimtane Ore. In Expert Mode, the Brain's Treasure Bag will drop some Tissue Samples.
 * The Creeper's 1/2 chance to drop a Heart is six times higher than the regular 1/12 chance of most other enemies.
 * The Creeper resembles the Phantasmal Sphere attack of the Moon Lord and his True Eyes of Cthulhu.
