A set of Mythril Clothes is a Clothing-class piece of armor found in Golden Sun: The Lost Age. It is acquired by giving a Mythril Silver to Sunshine the Blacksmith in Yallam, where he will randomly forge it into either that or four other items. Visually, the Mythril Clothes resembles a shirt glowing with a dark blue aura.
The Mythril Clothes features a defense rating of 49, and it increases the wearer's Critical Hit and Unleash Rate by 15%, a very practical effect. It is bought for 14900 coins while its resale value is 11175 coins. As Clothing, it can be worn by all Adepts.
In a perfect game, this can be considered a very practical piece of armor to possess and distribute multiple copies of, providing high defense and increasing the chance the Adept's weapon will Unleash by 15%. For warrior Adepts, this armor is practically unmatched. There is one armor titled Valkyrie Mail that essentially functions as a further enhanced version to the Mythril Clothes, with 53 defense and 20% additional Unleash rate, and that is the game's best body armor. However, since you can only get one of that armor, and it can only be worn by the four Warrior Adepts Isaac, Garet, Felix, and Piers, the Mythril Clothes becomes very useful for the other Adepts who need armor with specifications that come close to that of the Valkyrie Mail's. It can also be especially useful on either Ivan or Jenna, mage-Adepts who can also wield Light Blades like the powerful Tisiphone Edge. This armor can also be viewed as an upgrade over the Erinyes Tunic, a Clothing with 45 defense and 10% additional Unleash, and 5 extra Attack points as well.
