Tree Flute

The Tree Flute is an important item given to you by Baghi in Golden Sun: Dark Dawn, initially as a way of getting into Ayuthay. The Tree Flute allows certain passages to be revealed once played by encouraging the growth of trees and vines to lift stone walls. Playing the flute to the Ancient Tree in Ayuthay will allow you entrance into the castle. Later, it will awaken the Sand Prince, and start the boss battle for it. The flute will also reveal the true entrance to the the Ouroboros labyrinth.
