Burst Brooch

The Burst Brooch is a Utility Psynergy item featured in Golden Sun: The Lost Age. It bestows the Burst Psynergy, and it can destroy any cracked object.

It is located on the pinnacle of Tundaria Tower and is a core ingredient in the progression of the Great Eastern Sea segment of the game. The dungeon opens up for exploration once the Parch Psynergy is acquired from Aqua Rock, and the Burst Brooch is imperative in that it allows one of the three Prongs of the Trident of Ankohl to be extracted from a block of ice near the entrance of the tower. The Trident, which is eventually needed to get through the Sea of Time and the Poseidon boss, can only be forged at Champa once Briggs is allowed to flee Alhafra and return to the village, and this will only happen once Burst is used on the rock preventing the sailing ship from being fixed.
