The Parasites' Kiss

Thought to be the finest splinter pistol ever crafted, this weapon spits out crystalline darts bound with psycho-vampric circuitry. Upon biting into flesh, the target's very soul is leeched, one gasp of pain at a time, and transferred back to the gun's wielder. As the luckless victim withers and shrivels like rotten fruit, their murderer flushes with vigour and youth, revelling in their stolen life energies while their foe crumbles away to dust on the breeze.
