Psynergy Armor

A Psynergy Armor is an Armor-class bodywear available in both Golden Sun and Golden Sun: The Lost Age. In Golden Sun only one can be found in the game, in a chest in a hidden room behind a waterfall in Mercury Lighthouse, even though it is a "common" item. In The Lost Age, however, it is indeed sold as a common armor, in the general vendor at Mikasalla. Being an Armor-class piece of body protection, a Psynergy can be equipped on warrior-style Adepts, namely Isaac and Garet in the first game, along with Felix and Piers in the second. It increases the equipped Adept's base Defense rating by 21 points and base PP meter by 20 points. Its buy value is 1000 coins and its sell value is 750 coins.

In Golden Sun when the Psynergy Armor is able to be found, it is a very useful item and a substantial upgrade over whatever armor is currntly equipped. The boost to the equipped Adept's PP meter is very practical at that early point in the game, enough that it is a better piece of bodywear to equip than technically stronger pieces of armor that can be bought or found later, such as Chain Mails, which are almost ironically twice as valuable money-wise as the Psynergy Armor. Since it is not an Artifact, it will not appear in an armor vendor's Artifacts menu when it is eventually sold in the future.

In Golden Sun: The Lost Age, Psynergy Armor is sold commonly at the vendor at Mikasalla, which is extremely useful to the player. At that point you will most likely have found the Clothing Artifact Full Metal Vest, which has exactly the same defense rating as a Psynergy Armor. The best thing to do here is to buy one and equip it on Felix, and put the Full Metal Vest on one of the other two Adepts. Later on in the game, it is possible to acquire an even stronger armor for Felix, the Ixion Mail, but keep the Psynergy Armor in your inventory for later because when Piers joins your party later at Kibombo, he will be equipped with a Chain Mail, and the Psynergy Armor with its PP-meter boost would actually be preferable for Piers to wear over the slight defensive edge the Chain Mail would afford in comparison.
