Unfinished
My idea for the lore behind this creature is that it possesses such a love for slicing objects and animals, it even slices its own arm off at a young age. Rarely you'll find a Slasher that has both limbs, but if they do, its a sign of increased intelligence in that specimen, since they have the willpower not to, since they realize they can slash more with two arms rather than one. They're quite loud, since they constantly scratch the ground and walls, and they're often cast out from hordes, as they're known from attacking their own kin. They often hunt alone, slashing their victims and sapping their blood through their claws.
