The Stark Gun is a Legendary pair of pistols in Grand Piece Online. In one Battle Royale round on version 1.1.87, a player started with a Jitte, picked up the guns, moved all their points into Gun Mastery and Defense, and won a 24-player lobby. Most of that win came from fights in open water.
Quick answer: With 721 Gun Mastery and 751 Defense, the Stark Gun took 1st place with 11 kills, 23,503 damage to players, and MVP. Most kills came in the ocean.
Stark Gun moveset and Gun Mastery requirements
The Stark Gun was the final-tier reward in the Halloween Battle Pass and the Season 3 and Season 4 Battle Passes. Trading it requires trade level 475 or higher. It has three skills, which was a first for a Legendary weapon, since earlier ones had two. On the in-game hotbar, the guns also have a Block on F.
| Key | Skill | Gun Mastery | Stamina |
|---|---|---|---|
| E | Right Gun | 35 | 35 |
| R | Soul Wolves | 45 | 40 |
| Z | Cero Metralleta | 125 | Full Metralleta bar |
| F | Block | — | — |
Right Gun is a ranged energy burst. If you hold it, its range grows a lot and it becomes a block breaker. Soul Wolves sends wolves after nearby opponents. Cero Metralleta fires a wide arc of blasts, but only when the Metralleta bar is at 100%. A fully charged Metralleta also breaks blocks, so the guns have two ways to get through a guard.
Damage numbers differ depending on where they are listed. One figure puts base M1 damage at 8. Another lists a base of 6, an M1 cap of 32, a max of 124 (248 when fully charged), a 103 cap for the wolves, and a Gun Mastery stat cap of 775. Either way, the M1 hits are fast but scale poorly. Most of the damage comes from the skills. With Busoshoku V2, the gun lights and skill effects change to the player’s Spirit Colour.

Add to Google Preferences →The Gun Mastery and Defense stat build
The match opened inside a building with the Jitte. After a few close fights in town, the player got their first elimination. That kill awarded a Spirit Essence along with the message “You have received a Spirit Essence for getting your first elimination.”

About two minutes in, an SP Reset Essence cleared every stat point. The player put nothing into Strength or Sword Mastery. Gun Mastery ended at 721, close to the 775 cap and well above the 125 needed for Cero Metralleta.
| Stat | Points |
|---|---|
| Gun Mastery | 721 |
| Defense | 721, then 751 |
| Stamina | 250 |
| Strength | 0 |
| Sword Mastery | 0 |
Other Stark Gun rounds used similar builds. One player reached 800 Gun Mastery and 800 Defense. Another put 600 into Gun Mastery and 700 into Defense, plus 100 into Devil Fruit for Pika. The pattern is the same each time: high Gun Mastery, high Defense, and enough Stamina to keep using skills.
Stark Gun water combat in GPO Battle Royale
Fights in this round moved off the docks and into the open ocean, where several players were swimming and trading hits. Devil fruit users are weaker in water, and a ranged gun build is not. That difference decided most of the round.

After the stat reset, the player equipped the Stark Gun and opened with Cero Metralleta on players in the water. Cero Metralleta covers a wide arc, so it can hit several swimmers at once. The Metralleta bar also fills fast in a crowded fight.

Several eliminations followed in the next minute as the player kept firing at swimmers. Soul Wolves chase targets on their own, which helps against opponents who keep changing direction in the water.

Defeated players dropped valuable loot, including Mochi, Gura, Buddha, the Dullahan, and the Soul King’s Guitar. The player won two separate fights against scythe users near the pier, then used Cero Metralleta and rapid fire against another opponent in the middle of the bay.

Medium-range fights continued around the bay until the final circle started. Right Gun’s long charged range is useful here, but you can’t move while charging it. In open water, that is less risky because opponents need time to swim close.

Final circle: Ice Curse, the Venom user, and the last duel
Battle Royale includes a damage zone that covers the entire map within 20 minutes. When the final circle starts, the game shows “Final circle active: ULTIMATE AND MODE BARS have been reset!” The circle then moves and shrinks. In this round it pushed the remaining players back into town. Cero Metralleta does not count as an Ultimate in Battle Royale, but it still needs a full Metralleta bar, and that bar empties when you die.
Near the end, the player picked up the Ice Curse. It makes M1 hits leave targets vulnerable so they take more damage, which helps the Stark Gun’s weak M1 scaling. The player then fired at close range into an opponent using the giant Venom transformation and took them out on a rooftop at the edge of the zone. One more rooftop fight with Stark Gun shots ended the match and showed the “VICTORY” banner.
Match result and rewards
The end-of-match screen confirms the win, the stats, and the rewards. The player opened only one chest the whole round. Their gear came almost entirely from what defeated players dropped.
| Result | Value |
|---|---|
| Placement | 1st |
| Kills | 11 |
| Damage To Players | 23,503 |
| MVP | Yes |
| Chests Opened | 1 |
| Weekend bonus | +30,750 EXP |
| Fruit reward | Legendary Fruit Chest |
| Currency | +60,000 DELI |
| Other rewards | +10 Race Rerolls, +3 Tailor Tokens |
That result is high compared with other Stark Gun rounds. One win paired the guns with Rokushiki and Kamishiki and ended with 7 eliminations and 17,474 damage. Another round with Lava Curse ended in 2nd place with 5 eliminations and 18,787 damage.
Stark Gun weaknesses
The guns have a fast grip animation, quick M1s, and short startup on most skills. They also have clear weak points:
- Cero Metralleta has a long wind-up that leaves you open to attack.
- You can’t defend yourself while charging Right Gun.
- Soul Wolves have no hyper armor, so they can be interrupted.
- Its M1 attacks have limited reach, surpassing Knight’s Gauntlet by only a small amount.
- Dying empties the Metralleta bar.
The winning round avoided most of these problems by choosing where to fight. Open water kept opponents at a distance, which made the long charge and wind-up times less dangerous. Without a fruit, the player had nothing to lose from staying in the water. Back in town, the Ice Curse covered for the weak M1 damage. The Stark Gun is strongest when the fight stays at range, and in this round it mostly did.
