Ultimate Battle Piece Weapon List: Every Sword & How to Get It (2026)

If you're diving into the world of Grand Piece Online (GPO), you already know that having the right arsenal can make or break your journey. Whether you're a seasoned pirate or just setting sail, understanding the game's combat options is crucial. In this guide, we’ll break down the complete Battle Piece weapon list, covering everything from common starter blades to legendary event-exclusive loot. This comprehensive overview will help you decide which weapon to hunt for, how to upgrade your stats, and what makes each sword unique.

Understanding Weapon Categories and Stats

Before we jump into the Battle Piece weapon list, it's important to understand how weapons function in GPO. Swords are one of the four main combat forms, alongside Fighting Styles, Guns, and Devil Fruits. They are characterized by a relatively small moveset and short-range attacks, but they scale directly off your Sword Mastery stat. This means that the more you invest in this stat, the more damage your blade will deal.

Weapons in GPO are sorted into seven distinct rarities: Common, Uncommon, Rare, Epic, Legendary, Mythical, and Collectable. The drop rates and methods of obtaining these items vary wildly, from simple purchases to challenging boss fights and limited-time events. Additionally, each sword falls into a weight class: Light, Medium, or Heavy. This classification affects your attack speed and combo potential. Light swords are fast but hit softer, while Heavy swords are slow but pack a massive punch.

How Mastery and Stats Work

When you equip a sword, you'll notice it requires either Sword Mastery or Strength to use effectively. Most blades use Sword Mastery, but some unique weapons, like the Vrael's Pipe or the Sunken Anchor, scale with your Strength stat instead. This is a key distinction when building your character. If you’re focusing on a Strength-based build, you'll want to prioritize those specific weapons.

Another crucial mechanic is the 15-second cooldown reset. If you use a skill from one weapon and then switch to another, all your attacks will have their cooldowns reset for 15 seconds. This makes weapon swapping a high-risk, high-reward strategy that requires careful timing.

The Complete Battle Piece Weapon List (Obtainable Weapons)

Here is the core of our Battle Piece weapon list, focusing on weapons that are currently obtainable in the game. We've organized them by rarity to help you understand the power curve.

Common to Rare Weapons

These are your early-game workhorses. They are easy to obtain and will serve you well as you learn the ropes.

These weapons provide a solid foundation. The Katana is your first real blade, while the Kiribachi offers a taste of the Heavy playstyle. The Golden Hook is a fantastic early-to-mid game option due to its multiple obtainment methods.

Legendary Weapons (The Endgame Grind)

This is where the Battle Piece weapon list gets exciting. Legendary weapons are the primary goal for most players, offering unique moves and high damage output.

The Swordfish Rapier is a testament to the game's crafting system, rewarding players who invest time in the fishing mini-game. The Sunken Anchor is a top-tier Strength-based weapon, making it a must-have for Strength builds. The Raiui is a fast, reliable sword that can be earned through consistent raid participation.

Event-Exclusive and Limited Weapons

Many of the most prestigious and powerful weapons in GPO were only available for a limited time. These items are classified as Limited or Collectable and are often highly sought after in the trading community. Based on community reports, many of these will never return as a drop, making them true trophies.

Anniversary and Holiday Weapons

The developers host seasonal events that introduce unique weapons. Here’s a look at some of the most notable ones from the Battle Piece weapon list archives.

Note: Items marked with [UNOB] (Unobtainable) are no longer available through gameplay. According to player experience, these can only be acquired through trading with other players who were lucky enough to get them during the events.

Battle Pass and Crew Rewards

Some of the most exclusive items in the Battle Piece weapon list come from competitive play or premium battle passes.

The World Ender is a legendary weapon that many veteran players covet. The Iceborn Rapier is unique because it has a chance to return during the Christmas event, making it a semi-limited item. Finally, the Prestige Dark Blade is the ultimate status symbol, only held by members of the absolute best crews in the game. If a player leaves the crew, the weapon is removed from their inventory and cannot be traded.

How to Choose the Right Weapon for Your Build

With so many options in our Battle Piece weapon list, choosing the right one can be overwhelming. Here’s a simple guide based on your playstyle:

• For Speed and Combos: Focus on Light swords like the Katana, Raiui, or Hollow's Fang. These allow for quick, relentless attacks.
• For Raw Power: Heavy swords like the Kiribachi, Sunken Anchor, or World Ender are your best bet. They deal massive damage per hit but leave you vulnerable.
• For Versatility: Medium swords like the Golden Hook or Swordfish Rapier offer a balanced approach, good for both offense and defense.
• For Strength Builds: If you've invested heavily in the Strength stat, prioritize weapons like Vrael's Pipe, Sunken Anchor, or Elo's Sledgehammer.

Pro Tip: Don't Neglect Your Secondary

As the source material notes, swords are generally not designed to be used by themselves. They benefit greatly from having a secondary form of attack, such as a Devil Fruit or a Fighting Style. A common strategy is to use a sword for close-range pressure and a Devil Fruit for area denial or long-range pokes.

Trivia and Final Tips

Here are some final pieces of information from the community to help you on your journey:

• Fastest M1 Speed: According to the game's wiki, Hollow's Fang has the fastest basic attack (M1) speed in the entire game.
• The Unknown Nidai Kitetsu: There is a sword listed in the game's data called Nidai Kitetsu, but its rarity and obtainment method are currently unknown to the community. It may be a future addition to the Battle Piece weapon list.
• Fishing is King: Don't underestimate the fishing mini-game. It's the only way to get the Swordfish Rapier and the Sunken Anchor, two of the best weapons in the game.

Frequently Asked Questions

What is the best sword in the Battle Piece weapon list? There is no single "best" sword, as it depends on your build and playstyle. However, the Prestige Dark Blade and World Ender are widely considered top-tier for their raw stats and prestige. For obtainable weapons, the Sunken Anchor and Swordfish Rapier are excellent choices.

How do I get the Sunken Anchor in GPO? The Sunken Anchor is obtained exclusively through the fishing mini-game. You will need to fish in various locations until you are lucky enough to reel it in. It requires the Strength mastery to use effectively.

Can I still get event weapons from the Battle Piece weapon list? Most event weapons, like the Demon Jester's Scythe or Prestige Candy Cane, are marked as [UNOB] and are no longer obtainable through gameplay. Your only chance to acquire them is by trading with another player who has one.

What stat should I level for swords? For 90% of swords, you should level up Sword Mastery. However, always check the weapon's requirements. Weapons like the Sunken Anchor and Vrael's Pipe require Strength instead.
