          Return of the dart gun?28 Aug 2016 12:16  

          I already got the knee capper in a pipe gun, it helped with my second death claw.. But i just pulled another one, in the form of an auto shotgun. Does the 20% chance only occur per shot, or maybe per projectile? And it is fully auto, so you have to imagine death claws whimpering in fear of this.
