Onyxia

The Onyxia is a craftable post-Moon Lord gun that is the direct upgrade of the Onyx Chain Blaster. It rapidly fires bursts of six bullets at a time alongside an onyx blast that deals triple the damage of the fired bullets. The bullets from the Onyxia are fired in 3 symmetric pairs surrounding the onyx blast. It has a 50% chance to not consume ammo when fired.

Trivia
