Creeper

Creepers are eyeball-like hostile mobs 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.
 * Creepers are one of the few enemies that cannot pick up dropped coins in Expert Mode.
