Spiritualists are Monks, Priests, Shinto Miko's basically any of your holy or spiritually active that practice the art of banishing evil spirits.
~Shinto Miko The Miko draws power from one of the five pure elements. The spirits of that element assist her in purging the dark spirits or sending on lost ones but once drawn upon for example a tree spirit she must let it rest at least half a day or the power won't be there to call upon when needed again.
