List of Rings

There are many classes of "normal" defensive equipment in the Golden Sun series, but in addition there are several other classes of "supplemental" equipment that you get under special circumstances and can equip for extra benefits in addition to the normal equipment you're wearing. The pieces of armor listed here belong to the Ring class of supplemental equipment, which can be equipped by any party member to date.

All Rings are counted as Artifacts, meaning that they do not appear in the Buy menu of vendors. These are bought and sold individually and usually are unique, and if one appears in the Artifacts menu of a town's vendor that one ring can be bought by itself and then be sold by itself anytime afterwards to reappear in the Artifacts menu. The vendor shopkeeper will specifically remark about how rare a find your Artifact is whenever you specifically sell one.

The prices the games assign to each piece of equipment normally are quite reliable indicators of how good each equipment is as they measure against each other in actual battle. This does not necessarily hold true so much for rings, but for consistency's sake they are all arranged by price below anyway. Also, they are divided into groups based on what game they first appear in. Keep in mind that many of these rings continue to be used in later games, even if they are not listed under that game's list of Rings.

Trivia

 * Rings are the only equipment class present in previous games to feature almost entirely new equipment in Golden Sun: Dark Dawn.
 * Boots may also qualify, although this is debatable since many of the "new" boots in Dark Dawn were actually coded into Golden Sun: The Lost Age and were simply left unused.
