Gastric Belcher Staff

The Gastric Belcher Staff is a Hardmode summon weapon that drops from Leviathan and Anahita. When used, it summons a miniature variant of the Aquatic Aberration that floats by the player and attacks nearby enemies by firing gravity-affected vomit towards its targets. Every third attack, it instead fires a random spread of five bubbles with varying size. The bubbles stay still and linger after a short time if they haven't hit a target, and the vomit pierces up to two enemies.
