The Eradicator is a post-Moon Lord rogue boomerang that is dropped by The Devourer of Gods. When used, it throws a disk that passes through tiles and returns to the player after traveling a moderate distance. When thrown at nearby enemies, it will sporadically fire non-piercing nebula lasers that deal 40% of the weapon's damage.

Performing a stealth strike with the Eradicator causes the next boomerang thrown to not return to the player but slightly stick to enemies and rapidly fire lasers in random directions before dissipating. Some of the lasers fired are slightly affected by gravity while some of them are not.

Its best modifier is Flawless.
