Nail collectors are unusual creatures. They walk around with unusually shaped nail clippers, which seem to grab as well as they cut. For some reason, they love to collect f ingernails from their victims, leaving them with bloody, unusable messes by the time they finish.
Nail collectors walk around with large sacks that they fill with stolen fingernails. Each one has hundreds or even thousands of nails in their collection and will fight anyone to the death to protect it.
