Mysterious Robe

The Mysterious Robe (Shinbi no Robe/Robe of True Beauty in Japan) is a Robe found in Golden Sun: The Lost Age. Being a Robe, it can be equipped to Jenna, Ivan, Sheba, and Mia. It can be purchased upon arriving at Prox for 36500 coins, making it the most expensive item in the game (it is worth even more than the mighty Sol Blade). It can be sold for 27375 coins.

The Mysterious Robe increases the wearer's defense by 48, which is more than any other Robe (although the Mythril Clothes offer a slightly higher defense rating). However, as with most defensive Artifacts, it is not the defense itself that is most important; the Adept wearing the Mysterious Robe recovers 20 HP and 10 PP per turn. Although there are other pieces of equipment that restore some of the wearer’s HP and PP each turn, the Mysterious Robe is the only item in the game that does both. There is also no equipment that recovers as much HP as the Mysterious Robe, and only the Iris Robe and Psychic Circlet recover more PP.

The Mysterious Robe’s high HP and PP recovery rates, combined with its high defense rating and supported by its staggering price, makes this perhaps the best item in the game. Its impressive HP recovery keeps the wearer alive much longer than normal, and its PP recovery gives the wearer an essentially limitless supply of Psynergy. A good idea is to give this to someone with strong healing Psynergy, such as Mia in her default class, so that he/she can keep the rest of the party alive.

There are only four Robes that automatically restore HP (the Blessed Robe, the Oracle's Robe, the Muni Robe, and the Mysterious Robe), and only four Adepts who can wear Robes. For these Adepts, there is no other equipment that can restore HP automatically, making these four Robes very valuable items.
