Usage & Description
The weapon'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.
This weapon can also currently be used to damage the special Jakobs barrels carried by Thieving Jabbers, which drop cash when damaged, without actually ever destroying the barrel. This allows for an infinite source of money for as long as you're able to supply pistol ammo.
When at 1 HP, enemies hit by the Night Flyer will have "IMMUNE" appear.
The source, name, and special effect of the weapon are references to Batman and his personal code of not killing anyone.
