Heirloom Ring

The Heirloom Ring is a Ring-class piece of equipment introduced in Golden Sun: Dark Dawn. It is considered one of the greatest treasures of Ayuthay.

Basic Description
The Heirloom Ring increases the wearer's Mercury Power by 30 points and Mercury Resistance by 40 points. It can also be Used to restore 1000 Hit Points to one party member. It can be sold for 4200 coins and, being an Artifact, subsequently rebought for 5600 coins.

In Dark Dawn, the Heirloom Ring is found in the treasure chamber below King Paithos throne room in Ayuthay, which is only accessible after the Grave Eclipse begins. Being a Ring, it can be equipped by any party member.

Analysis
The Heirloom Ring is an excellent choice for any Adept that uses Mercury-based abilities on a regular basis. Although the Ring's equivalent of a free Pure Ply is beneficial, it should be used sparingly, as the Ring loses all benefits if it breaks. Because it is a Ring, its power can be stacked with any other armor the character has. For example, if the Heirloom Ring is combined with the Triton's Ward, the combined boosts can increase an Adept's Mercury Power and Mercury Resistance to near the maximum value of 200. For a Mercury Adept like Rief, this doubles the power of his Wish Psynergy series, allowing him to restore the party to full health after nearly any assault. Amiti, who by game's end will have access to at least two weapons with powerful Mercury-based Unleashes, also benefits, due to the increase in Power affecting the strength of his Unleashes.
