Darkserpent

The Darkserpent is a Post-Moon Lord and pre-War Mode ranged weapon, and is the upgrade to the Mechalodon. It fires at an insanely fast speed, has a slight inaccuracy, has a 25% chance to not consume ammo, and fires a rocket every 25 shots. The rocket itself deals 1.5x the damage of the weapon and explodes upon contact with a block or enemy. Normal types of bullets (Musket Balls, Silver Bullets) will gain the ability to pierce enemies, but bullets with special properties (Chlorophyte Bullets, Meteor Shots) will maintain those properties. It is one of the strongest guns before War Mode. Rockets have a 75% chance to perform a critical hit as well.

It's best modifier is Unreal.
