Merchant's Oath

Merchant's Oaths are unwritten agreements between Zunari and the Goron Merchants in The Legend of Zelda: The Wind Waker. After receiving the Delivery Bag and saving the girls from the Forsaken Fortress, Link creates these oaths for Zunari by trading certain items with the merchants. These items are flowers, flags, or other forms of decoration that are traded to be upgraded.
