Tank Killer

Tank Killer is a Perception-based perk in Fallout 76, and a perk in the Nuclear Winter battle royale mode.

Effects
Tank Killer reduces the physical and energy Damage Resistance of your target and adds a chance to stagger the target. However, it does not change the target's radiation, poison, frost or fire resistances.

Bugs
As of patch 1.4.0.20, the Adventure mode variant of Tank Killer 3 will not provide the 9% stagger chance for semi-automatic pistols, as it is missing the WeaponTypePistol keyword required to apply the stagger to that weapon type. The keyword is present for the 3% stagger rate for automatic pistols and will work as expected for automatic pistols as such.
