Necromancy

Necromancers explore the cosmic forces of life, death, and undeath. As you focus your studies in this tradition, you learn to manipulate the energy that animates all living things. As you progress, you learn to sap the life force from a creature as your magic destroys its body, transforming that vital energy into magical power you can manipulate.
Most people see necromancers as menacing, or even villainous, due to the close association with death. Not all necromancers are malevolent, but the forces they manipulate are considered taboo by many societies.
