Mirrored Shield

The Mirrored Shield is a Shield-class hand armor found throughout the Golden Sun series.

Basic Description by Game
The Mirrored Shield increases the wearer's base Defense by 39. In addition, it can be Used as an item during battle by an Adept who is able to equip it (but it does not necessarily have to be actually equipped) to emulate the Delude Psynergy to attempt to inflict the Delusion status condition on up to three enemies. It can be bought for 5200 coins and sold for 3900 coins. If broken, it can be sold for 2600 coins and repaired for 1300 coins.

It is bought as an artifact from the armor vendors at Lalivero in Golden Sun, at Contigo in Golden Sun: The Lost Age, and at Champa Camp in Golden Sun: Dark Dawn. As a Shield, it can be equipped by the warrior Adepts: Isaac, Garet, Felix, Piers, Matthew, Tyrell, and Eoleo.

Analysis
While it may have the highest Defense of all hand equipment in the first Golden Sun, it having just a Use effect - with that being an attempt at inflicting the unimpressive Delusion status condition on enemies - makes it only noteworthy for its Defense, and as it is, the shield is just barely one of the two best pieces of hand-armor for the warrior Adepts Isaac and Garet to be wearing, with the other being the War Gloves.

In The Lost Age, when it becomes available in Contigo as soon as the Great Western Sea can be sailed, though, the Aegis Shield you can get multiples of with Lucky Medals in Lemuria earlier are much better than it, because they have two more Defense points and a very useful 10% increase to the equipped Adept's chance to Unleash with his weapon. It should not be hard to find an improvement to replace the Mirrored Shield with if Isaac's party joins Felix's with the first game's Mirrored Shield equipped due to Password data transfer.

In Dark Dawn, the Mirrored Shield will be a placeholder for stronger and more useful armwear such as the Aegis Shield and the Cosmos Shield. It is available as soon as the player gains the ship. Since Eoleo joins the party with only weak Leather Gloves, the Mirrored Shield is an option for him until the player can gain the stronger Shields.

Trivia

 * The Mirrored Shield and the first game's Dragon Shield are the only Shield Artifacts to appear in every entry of the Golden Sun series. What separates the two is that the Mirrored Shield is guaranteed to appear in Golden Sun: The Lost Age, but the Dragon Shield will only appear if it's in the player's inventory when they transfer data from the first game to The Lost Age.
