The mystic caste of the Sahagin race is characterized by lighter scales than the warrior caste. They also commonly are covered with rags and strips of cloth, often adorned with shells and other undersea paraphernalia. They secrete the same oily substance as warriors, but to a lesser degree.
They have magic related to water and the sea. Many have only ritual abilities, but some have shown the ability to cast spells 'on the fly.'
