Sea God's Tear

The Sea God's Tear is a Rare item in Golden Sun: The Lost Age. It is found in Daila's Sanctum, held by the big statue, but you cannot get it until later in the game when Piers has joined your party so you can use Frost to be able to reach it. The Tear is to be placed in the hands of a similar statue within the Shrine of the Sea God dungeon, which causes it to elevate you to the upper floor where the shrine's main prize, a prong to the Trident of Ankohl, awaits. After you get it, you can sell it as it is no longer useful, and takes up inventory space.
