The One Piece token is Pirate Shop Access
Epic describes Pirate Shop Access as a rare reward from a Supreme Treasure, with eligible Item Shop access for 14 days after activation. Check the game’s eligibility and timing before assuming a particular item is included.
Weekly gold outfits and the pass
The weekly gold reward and Pirate Shop Access are separate possible Supreme Treasure rewards. The regular pass and the rotating Item Shop have their own unlock and purchase routes. If you want a specific outfit, check the current shop or pass before hunting for random rewards.
How to plan a session
Try the normal Treasure Hunters objectives in Battle Royale while you search for better treasures. Epic’s announcement does not promise a token per run, so judge a route by how many safe attempts it gives you.
