I have one rule. – Increased damage and fire rate. Will damage enemies until they are at 1 HP, at which point it won't deal anymore damage. Full auto while airborne. Alternative Fire mode toggles the zoom magnification.
Usage & Description
The Night Flyer's special effect can be used to help a teammate achieve a second wind by guaranteeing they get the kill, as well as helping characters complete challenges which require kills under specific circumstances.
The Night Flyer can also be used to damage the special Jakobs barrels carried by Thieving Jabbers which drop cash when damaged, without destroying the barrel. This allows for money to be obtained for as long as the character has pistol ammo.
Attempting to damage enemies at 1HP with this weapon will result in the word "IMMUNE" spawning, similar to the "RESIST" phrase (I.E. Using an incendiary weapon on a shield).
The source, name, and special effect of the weapon are references to Batman and his personal code of not killing anyone.
