Sin eaters can feel the emotions of others, & they thrive off the negative emotions, especially depression. Using this, they can attach themselves to the souls of their victims, nurturing their sins & feeding off them. A good sin eater will suck the sins right off the soul, but an evil one will exacerbate the sins into worse sins.

Sin eaters can cause sins to manifest as physical sores, either on themselves or others, if they burn off the sins they have gathered. They can affect other empath subraces.

They are resistant to normal dieases & poisons.
