What Is Sailor Piece Mastery
Sailor Piece Mastery is a progression system that grants permanent stat bonuses to your chosen combat tool based on the number of enemies you defeat with it. The system was introduced in the Ghoul update and has become essential for players who want to reach endgame content and deal maximum damage.
Here is how it works: every weapon and melee fighting style in the game has its own separate Mastery track. When you equip a weapon and defeat enemies, each kill counts toward that specific weapon’s Mastery level. Once you accumulate 25 kills, you gain 1 Mastery Point. This means reaching the maximum level of 500 Mastery requires 12,500 total kills with that specific combat tool.
The rewards for investing time into Mastery are substantial. At maximum level, you receive a permanent 25% chance to deal 1.5x damage on any attack. This passive ability alone can dramatically increase your average DPS. Combined with the milestone stat bonuses you earn along the way, maxing out Mastery on your favorite weapons should be a top priority for serious players.
Complete Sailor Piece Mastery Milestones Table
The Mastery system features 11 milestone levels, each granting specific stat bonuses when reached. These milestones are spaced every 50 levels from 50 to 500, giving you consistent rewards as you grind. The table below shows every milestone and the exact bonuses you receive at each one.
Total stat bonuses at Mastery 500 include 32% Luck, 32% Damage, 2% Crit Chance, and 25% Crit Damage. The Luck bonus is particularly valuable for improving drop rates on rare items, which is why many players prioritize Mastery farming early.

Notice how the Crit Chance and Crit Damage bonuses become more prominent at higher milestones. These stats are crucial for pushing your damage into the high billions range, making the later milestones especially valuable for endgame players.
How to Access Mastery in Sailor Piece
There are two ways to check your Mastery progress in Sailor Piece. Both methods were introduced with the Ghoul update and allow you to track which weapons you have been leveling.
Method 1: Talk to the Mastery NPC
Head to Starter Island and locate the Mastery NPC. This character will show you the Mastery levels for all your equipped and stored combat tools. The NPC interface displays your current Mastery Points and how close you are to the next milestone. This is the most reliable way to check progress on weapons you are not currently using.
Method 2: Check Your Inventory
For a quicker option, open your inventory and select any weapon or melee style. The Mastery information will display directly in the item description, showing your current level and progress toward the next milestone. This method is faster when you want to check the weapon you are currently farming with.
How to Level Up Mastery Fast
Reaching Mastery 500 takes 12,500 kills, which sounds daunting but can be achieved efficiently with the right strategy. After testing multiple methods and reviewing community feedback, the Quake fruit swap method stands out as the fastest way to farm Mastery in Sailor Piece.
The Quake Fruit Swap Method
This method leverages the Power stat and the Auto C skill mechanic to farm kills at an accelerated rate. Here is how it works:
Step 1: Equip the weapon or melee style you want to level.
Step 2: Obtain the Quake fruit and equip it.
Step 3: Use the Auto C skill from the Quake fruit to deal massive area-of-effect damage.
Step 4: Quickly swap back to your target weapon before the enemies die.
Step 5: The kills count toward your equipped weapon’s Mastery even though Quake dealt the damage.
This method works because the game registers kills based on which weapon you have equipped at the moment of death, not which ability dealt the damage. The Quake fruit’s Auto C skill provides excellent AoE coverage, letting you clear large groups of enemies instantly.
Important: You need a high Power stat for this method to be effective. The Quake fruit’s damage scales with Power, so invest in this stat to one-shot enemy groups. Without sufficient Power, you will leave enemies wounded but not dead, wasting time.
Best Weapons for Mastery Farming
While the Quake method works with any weapon, some combat tools naturally clear enemies faster than others. Weapons with wide AoE attacks or fast attack speeds will feel smoother when farming normally without the Quake swap technique.
The World sword is one of the top recommendations from the community for Mastery grinding. Its fast attacks and good range make it efficient for clearing enemy groups. If you do not have The World yet, check our guide on how to get The World sword for step-by-step instructions.
For a complete breakdown of which weapons perform best, see our tier list for the best weapons. The top-tier swords and melee styles mentioned there are ideal candidates for maxing out Mastery first.
2x Mastery Game Pass Value
For players serious about maxing multiple weapons, the 2x Mastery Game Pass costs 699 Robux and doubles your Mastery Point gains. This effectively cuts your grinding time in half, reducing the total kills needed from 12,500 to 6,250 per weapon.
Is it worth it? If you plan to max out more than three or four weapons, the time savings add up significantly. The pass applies to all combat tools, so your investment continues paying off as you work through different weapons and melee styles. For casual players focusing on just one main weapon, manual grinding with the Quake method may be sufficient.
Best Farming Locations
Enemy density matters more than enemy strength when farming Mastery. Look for areas where enemies spawn in tight clusters that you can clear with single attacks. Slime Island is frequently mentioned by the community as a solid spot for grinding, especially since you can pick up materials and the Broken Sword while working on Mastery.
Ice Queen’s area is another high-density spot recommended for AoE farming. The enemies there spawn close together and respawn quickly, letting you maintain a fast kill pace. Experiment with different zones to find what works best for your current damage output and farming setup.
