While exploring the Island of Waford in One Piece Odyssey, you’re bound to find loads of treasures along the way. One such category of treasure is the Locked Chest which contains resources vital to your survival on the island provided you have a chest key to open them with. Below is a guide on where you can find the locked chests in Alabasta. Opening all of them rewards you with the Treasure Hunter trophy/achievement.
