Grand Piece Online just entered a completely new era with the arrival of Whole Cake Island Part 1, and this update is easily one of the biggest content drops the game has ever received. From raising the level cap to 675, introducing two brand-new Mythical Devil Fruits, and adding a full raid tower system with puzzle floors, mirror worlds, and world events, this update changes how progression, farming, and PvP work across Second Sea.
Whole Cake Island isn’t just another island added to the map — it is an endgame hub built around boss raids, cooperative world events, capture-the-flag PvP, new cosmetic progression, and some of the strongest weapons and accessories ever released. Whether you are here to chase Dragon or Soul, farm Big Mama, dominate Infamy zones, or hunt exclusive Iceborn gear, this update gives you more ways to grow your account than any previous patch.
