Dr. Nusakan is a character from SaGa Frontier.
He is a Mystic doctor that runs his clinic at Pidona Slums.
He is recruitable during "Muse's Nightmare" event.
One of the best Mystics, because of his decent statuses and his Mystic Coat, which enables him to heal allies without any cost, equip armour and suits, a very unique trait.
He starts with the Sunspot Destroyer Spell Art, useful for long parts of the hack.
But he eventually gets overshadowed by both Asellus and Zozma due for Asellus has cosplay item and Zozma has higher offensive statuses, but if you don't have patience for raising another Mystic, Nusakan can carry his job nicely as a fighter, magician or support character.
