Guardian Ring

The Guardian Ring is a Ring-class piece of equipment found in Golden Sun: The Lost Age.

Basic Description
The Guardian Ring is located in a treasure chest in the earlier parts of the Yampi Desert. It can be bought for 1700 coins and sold for 1275 coins.

The Guardian Ring is unusual among Rings in that it doesn't have to be Used to activate its effect (the only other Ring that behaves this way, prior to Golden Sun: Dark Dawn, is the Cleric's Ring). Having the Guardian Ring equipped increases its wearer's Defense by 4 and their maximum Hit Points by 20.

Analysis
The Guardian Ring is often hailed as being one of the best Rings available because, if given to a weaker character, it can greatly improve their chances of surviving heavier battles. This Ring is often given to Sheba as soon as it's found, automatically putting her stamina well above its normal level. Because it is found at such an early point in the game, the Ring also has a long time to be used, making its usefulness grow even more.
