The Heavenly Volley is a Post Moon-Lord bow that is obtainable after collecting the Poseidon's Wrath, Elemental Wrath, Eclipse and Spectral Shot. It has a very high damage and speed stat, and fires 5 arrows similar to the Tsunami. Falling stars are also present, which resemble those created by the Star Wrath. Fireballs also fall from the sky. A beam similar to the Shadowbeam Staff also comes from the skies when shooting. To top it off, it fires Razorblade Typhoon(s) from your position to cursor.
The Heavenly Volley is the most powerful bow in the entirety of the Archery Mod, and is capable of annihilating any boss the player may encounter, including the Moon Lord.
