The Archerfish is a Pre-Hardmode gun obtained from Shadow Chests in the Abyss. If Musket Balls are used as ammo, bullets are replaced with a stream of water in a similar fashion to the Water Gun, albeit much faster and damage-dealing, and can pierce up to 2 enemies before dissipating upon hitting a third.
Its best modifier is Unreal.
- This weapon can also be obtained from the Abyssal Crate after either The Slime God or Wall of Flesh have been defeated.
- The Archerfish is a fish in real life, which shoots a stream of water out of its mouth to hit insects above the water.
