Chain Mail

A Chain Mail is an Armor-class bodywear available throughout the Golden Sun series.

In and
In Golden Sun, Chain Mail is not a recommended purchase when it first appears at Altin due to the fact that the player usually has access to more useful armor like the Psynergy Armor in Mercury Lighthouse and the Elven Shirt in Mogall Forest, whose additional effects more than make up for the fact they each have just a few Defense points less than a Chain Mail. It continues to be sold at Kalay.

In Golden Sun: The Lost Age, Chain Mail can be bought at Kibombo after the Gabomba Statue dungeon and related events. Out of the two warriors capable of equipping it, Piers will start with Chain Mail as his default bodywear, and Felix will be equipped with a Psynergy Armor bought much earlier at Mikasalla. A Psynergy Armor, quite frankly, is better than a Chain Mail even though its monetary value is literally half as much and it has a few less defense points, because it has a significant PP-meter boost that is very useful at that point in the game. It is possible Felix will have found the Ixion Mail in Alhafra before going to Kibombo, so if he has a spare unequipped Psynergy Armor in his inventory when he meets Piers it would be sound to replace Piers' Chain Mail with that armor as soon as the latter joins.

In
In Golden Sun: Dark Dawn, Chain Mail is certainly not a good purchase by the point in the game Te Rya Village is reached and its vendors are accessed. In addition to Psynergy Armor having been available already at Passaj, even reaching that point in the game means passing through The Ouroboros, which contains the Ixion Mail, and Craggy Peak Ruins, in which a chest contains the Spiked Armor. Even if the higher Defense points compared to the Psynergy Armor are desired, those two armors have even higher Defense than the Chain Mail, and they have their own beneficial effects on top of that. At the time, only two available characters can even be equipped with armor in the first place, so the Chain Mail is completely outclassed from the moment it becomes available, and therefore it should not see any use.
