Infused Tattoo

In ages past there were those who were granted boons from extraplanar entities. Overtime these peoples became knowledgeable in many rituals to further enhance themselves past what the boons allowed. Currently only a few of the decendents of these peoples still know these rituals. The ritual itself is just the application of a tattoo, the design and size of the tattoo doesn't matter, just so as long as you have it applied to your body the ritual will be successful.
Known problems with this technology occur after an individual attempts to recieve a second tattoo. Its been documented that once a sailor recieved a second tattoo and died shortly after, due to as what he discribed as "Me flesh, it burns with the fury of the ocean. I can feel my body being singed from the inside out." His eyes then erupted into flames and he died.
