The Black Anurian is a Pre-Hardmode magic weapon obtained from Shadow Chests in the Abyss. It shoots violet bubbles that travel in an upward arc, alongside two homing planktons which are fired in a random spread. All projectiles fired deal half damage instead of full.
Its best modifier is Mythical.
- Its name is a reference to the biological order which frogs belong to, known as "Anura". This is reflected in the weapon's frog-like appearance.
