Blood Mage

Blood mages come by their power either by accident or by the teachings of evil such as dabbling in forbidden arcane lore or perhaps they were taught by a demon or fiend. They are more feared than many mages including necromancers, as they often dabble in necromancy as well, and are second in power only to lich's, demons, and fiends. With their blood fueling their magic giving them access to more powerful effects and with a willingness to sacrifice their own vitality to provide that fuel Blood Mages become a force that few would dare reckon with.
