Necromancer

The necromancer can control the forces of undeath, shadow, and disease to manipulate the soul and deal damage to enemies and heal allies. They focus on diminishing the brightness of the soul to reduce the ability for the body to heal, while also learning the ability to manipulate the souls around them, letting them steal life energy from opponents and even giving it to allies. They are also experts in shadow magic, allowing them to hinder their opponent's ability to use their senses. Due to the fact that they are experts of disease they are able to inflict and cure ailments.
