One Piece Odyssey Locked Chests Guide

One Piece Odyssey features the latest adventures of Luffy and his crew, as they travel across a mysterious island and relive the memories of their past. As you'd expect from a game about pirates, there's plenty of loot to find. However, some of the chests you encounter look much fancier than the regular variety, and cannot be opened by default. In our One Piece Odyssey Locked Chests Guide, we'll go over what you need to unlock these strange chests, and where to find all of them.

One Piece Odyssey Treasure Chest Key

The Treasure Chest Key is the (literal) key to the problem of locked chests, allowing you to open all 22 of them once obtained. However, the quest for the key is a journey in itself, requiring you to complete the multi-part Grand Line Quiz quest chain. For a full overview of these quests, make sure to check out our One Piece Odyssey Quiz Guide. With the Treasure Chest Key in your possession, it's now time to actually hunt down each chest. Locked chests are scattered across each main area of One Piece Odyssey, including the final dungeon.

Opening every locked chest will net you the Treasure Hunter achievement (or trophy if for PlayStation gamers).
