The Thunder Club and Leopard Fruit are two of the rarest new items in Grand Piece Online Update 13. Both are tied to Blossom Falls, the fresh island in the Second Sea, and both carry Mythical rarity. The path to each one runs through the new Dragon Emperor Dungeon, but they drop in different ways, so knowing exactly where to farm saves a lot of wasted runs.
Quick answer: Farm the Dragon Emperor Dungeon on Blossom Falls. The Thunder Club is a 0.1% direct drop from defeating the Dragon Emperor boss. The Leopard Fruit comes from Mythical Fruit Chests or as the dungeon MVP’s random Fruit reward, since Mythical Fruits sit at a 0.5% rarity tier.
Where to start: Blossom Falls and the Dragon Emperor Dungeon
Blossom Falls is located in the Second Sea, slightly southwest of Whole Cake Island. The island holds the entrance to the Dragon Emperor Dungeon, which is the source of every item covered here. It also has training dummies and PvP pads, which are useful for testing the Thunder Club or Leopard once you get them.
The dungeon is multi-stage rather than a single boss fight. You work through several objectives, guided by an on-screen objective UI, before reaching the final boss. Two quality-of-life changes make repeated runs less painful. All five Geppos regenerate the moment you touch the ground, and you can now store Fruits while inside a dungeon.
How to get the Thunder Club (0.1% Dragon Emperor drop)
The Thunder Club is a Mythical weapon that drops only from the Dragon Emperor, the final boss of the dungeon. Its drop rate is 0.1%, which makes it one of the rarest items in the entire update. There is no shortcut. You clear the dungeon, defeat the boss, and hope the roll lands.
| Dragon Emperor drop | Rarity | Drop rate |
|---|---|---|
| Thunder Club | Mythical | 0.1% |
| Dragon Emperor’s Cape | Cosmetic | 3% |
| Dragon Emperor’s Outfit | Cosmetic | 3% |
| Dragon Emperor’s Gourd | Cosmetic | 3% |
When the Thunder Club drops, you get the weapon plus the 雷鳴八卦 (Raimei Hakke) title at the same time. The title unlock is the clearest confirmation that the roll worked, so watch for it after the kill. You can inspect and equip the weapon from your inventory right away.
Tip: Defeating the Dragon Emperor 25 times unlocks the Dragon Slayer title, which grants 10% extra damage against the Dragon Emperor. Since you will be farming this boss anyway for the 0.1% weapon, that perk speeds up every future run.
Thunder Club moveset
The Thunder Club leans on hyper armor and block breaks, making it aggressive in close combat. Each move has clear properties you can plan combos around.
| Key | Move | Properties |
|---|---|---|
| E | Brutal Upswing | Holdable, hyper armor, charges up to 3 for scaling damage, blockable, block breaks after the 2nd charge |
| R | Tyrant’s Raze | Daze, holdable, hyper armor, block break |
| Z | Thunder Bagua | Hyper armor, block break |
| X | Direct Destruction | Grab, block breaks |
The weapon is custom tailorable, so you can change its colors, textures, and VFX through Ash the Tailor in a safe zone once you own it.
How to get the Leopard Fruit (Mythical, 0.5% tier)
Leopard is a new Mythical Fruit added in Update 13. Mythical is the top rarity tier in GPO at 0.5%, so this is a rare pull no matter how you go after it. There are two reliable routes tied to the same dungeon content.
The first route is the Mythical Fruit Chest. You open the chest and spin, and Leopard is one of the possible Mythical rolls. The second route is the dungeon MVP reward. Whoever earns MVP of a Dragon Emperor Dungeon run receives a random Fruit, which gives high performers another shot at a Mythical pull.
More broadly, GPO Fruits can come from natural spawns, dungeon wave clears, sea bosses, ship farming, Battle Royale, Colosseum and Factory Raid drops in Dressrosa, Karoo Racing, the Battle Pass, and player trading. Any of those can theoretically produce a Mythical, but the Fruit Chest and dungeon MVP reward are the direct ways tied to the new content.
Leopard Fruit abilities and transformation
Leopard Ascension has two modes, Speed Mode and Fighting Mode, and you swap between them with Predator Shift. Damage you deal with Rokushiki and Kamishiki fills the mode bar, so staying aggressive builds toward the transformation you want.
One notable interaction is that Kamishiki can be used in base human form while you have Leopard equipped. The Leopard Hybrid transformation requirement was also lowered after launch, dropping from 75% to 60%, which makes the hybrid form easier to reach. Like the Thunder Club, Leopard is custom tailorable through the Custom Tailor.
Redeem the Update 13 codes first
Before you start farming, grab the current Update 13 codes. The ILOVEGPO code is the most relevant here, since customizing the Thunder Club or Leopard costs a Tailor Voucher, and one voucher covers the entire customization cost of a Fruit, Fighting Style, or weapon no matter how many tabs you change.
| Code | Reward |
|---|---|
| ILOVEGPO | 5 free Tailor Vouchers |
| FREE_Drops5 | Free drop-related rewards |
| FREE_EXP5 | Free EXP |
Codes do not stay active forever, so redeem them before they expire. Between the guaranteed vouchers and the two farming routes on Blossom Falls, the plan is straightforward even if the drops themselves are not. Run the Dragon Emperor Dungeon, kill the boss for the 0.1% Thunder Club, and chase Leopard through Mythical Fruit Chests or the MVP reward. The 25-kill Dragon Slayer title makes each of those runs a little faster along the way.
