Emetical Gatekeeper

The Emetical Gatekeeper is a Hardmode, post-Plantera magic weapon that casts a mouth where the player aims. It is found in the Corrosion Chest of Dungeons in Corrosion worlds, which must be unlocked with a Corrosion Key.

It summons a large stationary mouth that opens and projectile vomits at enemies who get within 15 tiles of the mouth, being able to attack three enemies at once. The vomit projectile is affected by gravity and inflicts the Corroding debuff. The mouth despawns after 8 seconds, or when the player summons another mouth.

Its best modifier is Mythical.
