Tolten will be alone in this fight. Its not hard, but pretty interesting. Golden Knight will tell Tolten what to do : Attack, Defend, Heal. Once he will tell Tolten to defend use Complete Defense (if he has learned it, otherwise defend normally), Golden Knight will use Ultimate Hit. After that check your skills, you will have Ultimate Hit. Use it and the fight will be over. After the fight you will get Age of the King and King Ring as well as a new ability Ultimate Hit.
