Spirit Armor

A Spirit Armor is an Armor-class piece of armor found in Golden Sun. Visually, the Spirit Armor resembles green body armor, similar to the yellow Dragon Scales.

Basic Description
Spirit Armor increases the wearer's base Defense by 32 points, and increases the Adept's Resistance to all four elements by 15 points each. It can be sold for 3000 coins and subsequently rebought for 4000 coins.

In Golden Sun, it is acquired randomly as a prize from Tolbi's Lucky Medal Fountain. It can be worn by Isaac and Garet in Golden Sun, and if transferred into The Lost Age, also by Felix and Piers.

Analysis
Spirit Armor is one of the many pieces of equipment that can be won at Tolbi's spring and be used to outfit the party, replacing any outdated equipment. When compared to the other body armor at the spring, the Kimono and the Cocktail Dress, the Spirit Armor gives the highest Defensive increase, and arguably the best side-effect, its 15 point boost to all four resistances. It would doubtless be a good fit on Isaac and Garet, but for Garet one might also want to consider equipping the Kimono instead for the agility boost, for Garet is normally a slow Adept when he is under the influence of the default Guard class series. By the time stronger equipment, such as the Dragon Scales, is available, the game will be near its end.
