The first known instance of making and applying gemstone tatoos was
the devout of Vertos during the Cabbalum. The tattoos alter a person's
physical capabilities, either increasing an ability score, or granting
resistance to a damage type, depending on the gemstone used. A
creature can only have one such tattoo. The gem dusts in the amounts
