What Is the Sailor Piece Index?
The Sailor Piece Index is a permanent collection tracking system that rewards you for owning unique items across multiple gear and progression categories in the game. Unlike temporary buffs or consumable upgrades, every stat bonus you earn through the Index stays with your account forever. The system tallies how many distinct items you have obtained from categories like weapons, races, clans, auras, and more, then applies cumulative percentage-based buffs to your character stats at specific milestone thresholds.
How the Index System Works
At its core, the Index tracks a running total of unique entries you have acquired. There are 229 total possible entries spread across 11 categories, and you need 200 of those entries to achieve the maximum available buffs. Every time you obtain a new item that qualifies for the Index, it is automatically added to your entry count the moment you acquire it. There is no manual registration or NPC interaction required to count items, though you can visit the Index NPC to view your current progress and see which categories still have missing entries.
The 11 categories that contribute to your Index total are Melees, Swords, Clans, Races, Auras, Traits, Runes, Cosmetics, Relics, Bloodlines, and Titles. Each category contains a specific set of items you can earn through gameplay, rerolling, boss drops, crate openings, or special events. The more categories you diversify across, the faster you can grow your entry count because many categories offer dozens of different items to pursue.
Why the Index Matters for Your Build
What makes the Sailor Piece Index particularly valuable is that its buffs are percentage-based and permanent. Unlike flat stat bonuses that may become less relevant as you level up, percentage buffs scale with your character’s base stats and equipment, meaning they remain impactful throughout your entire progression. The maximum buffs at 200 entries grant you +22.5% Damage, +25% Luck, +22.5% Crit Damage, +3.5% Crit Chance, and +15% HP, which combined represent a massive boost to your overall combat effectiveness and survivability.
These buffs also stack multiplicatively with other percentage-based upgrades in the game, making the Index one of the best long-term investments you can make in your build. Whether you prefer melee-focused combat, sword techniques, or a hybrid approach, the stat increases from the Index apply universally to all your actions, making every farming session double as progress toward permanent power.
Where to Find the Index NPC
The Index NPC is the central hub for viewing your collection progress and understanding which categories still have items for you to pursue. There are two Index NPC locations in the game, one in Sea 1 and one in Sea 2, so you can access your Index information regardless of which sea you are currently playing in.
Index NPC in Sea 1
In Sea 1, the Index NPC is located in the main spawn area near the center of the starting island. Look for an NPC with a distinctive icon that resembles a collection or inventory symbol. The NPC stands in a prominent location that is easy to reach within seconds of spawning, making it convenient to check your progress frequently as you play. New players should make a note of this location early on since you will be visiting it often to track your progress toward milestones.
Index NPC in Sea 2
In Sea 2, the Index NPC is similarly positioned in a central spawn location, though the exact coordinates differ due to the sea’s larger map size and different layout. Players who have progressed to Sea 2 will find the NPC in the main hub area, typically near other important service NPCs like the reroll merchant, exp multipliers, and trading posts. The Sea 2 Index NPC provides the same functionality as the Sea 1 version, allowing you to view your complete entry count, see category breakdowns, and identify which specific items you are still missing.
All 11 Sailor Piece Index Categories
The Sailor Piece Index is divided into 11 distinct categories, each containing a pool of collectible items. Understanding what each category holds helps you strategize your farming efforts and prioritize the fastest paths to 200 entries. Below is a comprehensive breakdown of every category in the Sailor Piece Index.
Melees
Melees are close-combat weapons that serve as foundational gear for many players early in the game. This category includes a wide variety of fist weapons, blunt instruments, and short-range tools that can be obtained through gameplay, boss drops, or crate openings. Melees often have lower rarity floors compared to swords, making many entries in this category relatively accessible to acquire through consistent farming and rerolling.
Swords
Swords represent one of the most popular weapon categories in Sailor Piece, offering both variety and potency for players who prefer blade-based combat. The swords category includes numerous distinct sword types with different move sets, damage profiles, and unlock requirements. Many swords require specific boss kills or puzzle solutions to obtain, making this a category that rewards diverse gameplay engagement. Swords typically have a higher rarity ceiling than melees, meaning you may need more farming sessions to complete the full swords section of your Index.
Clans
Clans are organizational affiliations you can join within Sailor Piece, each offering unique bonuses and thematic identities. The clans category tracks which clans you have been a member of at any point, so even if you switch clans later, your entry in this category is preserved. Some clans require certain achievement thresholds or quest completions to join, making this a category that encourages long-term engagement with the game’s social and progression systems.
Races
Races are character templates that determine your base stats, speed, and sometimes grant unique passive abilities. The races category tracks which race types you have unlocked, with each race offering a different gameplay feel and stat distribution. Some races are unlocked through story progression, while others require specific item trades or special event participation. Racing through multiple race options allows you to experiment with different playstyles while simultaneously building your Index count.
Auras
Auras are visual and statistical effects that surround your character, often providing combat bonuses or unique interactions with the environment. This category includes a diverse array of aura types, each with distinct visuals and stat modifiers. Auras can be obtained through crate openings, boss drops, quest completions, and special events. Some auras are purely cosmetic in visual design but still contribute meaningful stat bonuses to your Index total.
Traits
Traits are passive abilities or stat modifiers that define how your character behaves in combat and exploration. The traits category includes dozens of different options that can dramatically alter your gameplay experience. Traits are typically unlocked through level progression, quest completions, or special item acquisitions. Many players find that exploring different trait combinations is one of the most enjoyable aspects of building toward the Index, as each new trait opens up strategic possibilities.
Runes
Runes are magical inscriptions that provide various combat and utility bonuses when equipped. This category includes a broad selection of rune types with different effects, from damage amplification to defensive barriers and special attack modifiers. Runes can be discovered through exploration, purchased from merchants, or earned through high-difficulty content. Completing the runes category often requires dedicated farming runs and trading with other players for rare variants.
Cosmetics
Cosmetics cover the visual appearance items in Sailor Piece, including hats, outfits, accessories, and other aesthetic modifications that do not affect gameplay stats directly. Despite being visual-only items, cosmetics still count toward your Index total and contribute to your milestone progress. This category includes both limited-time event cosmetics and permanently available items, making it one of the more time-intensive categories to fully complete due to event exclusivity.
Relics
Relics are powerful collectible items that often carry significant lore and gameplay weight. The relics category includes ancient artifacts, legendary objects, and unique finds that typically require substantial effort to obtain. Relics often provide substantial stat bonuses and may unlock special content or areas within the game world. This category tends to be one of the more challenging to complete fully due to the rarity and acquisition difficulty of many relic items.
Bloodlines
Bloodlines are hereditary abilities and stat lines that define powerful character templates passed down through in-game lineage systems. The bloodlines category tracks which bloodline types you have unlocked, with each offering distinct combat styles and passive abilities. Bloodlines often require specific achievement completions, boss defeats, or rare item trades to access. Completing this category represents a major commitment to exploring the deeper systems of Sailor Piece.
Titles
Titles are earned designations that appear above your character’s name, reflecting specific achievements, ranks, or milestones you have accomplished. The titles category is one of the most diverse, containing dozens of entries ranging from easy-to-earn beginner titles to extremely difficult achievement-based titles. Some titles require completing specific in-game challenges, reaching high leaderboard positions, or participating in limited-time events. Note that certain leaderboard-specific titles may not count toward the Index, so focus on achievable title farming methods.
Sailor Piece Index Milestone Rewards
As you accumulate entries in the Sailor Piece Index, you unlock milestone rewards at specific thresholds. These rewards consist of permanent percentage-based stat increases that stack with each other, meaning the closer you get to 200 entries, the more powerful your character becomes. Here is the complete milestone rewards breakdown.
Early Game Rewards (5 to 50 Entries)
Your first milestone arrives at just 5 entries, giving you a taste of the permanent power scaling the Index provides. From 5 entries through 50 entries, you will receive steady increments to your Damage, Luck, Crit Damage, Crit Chance, and HP stats. These early milestones are designed to give new players immediate tangible benefits for engaging with the collection system, encouraging them to continue exploring different item categories. The early phase rewards are particularly valuable because they arrive quickly as you naturally collect your first dozens of items through normal gameplay progression.
Mid Game Rewards (55 to 150 Entries)
Between 55 and 150 entries, the stat bonuses become more substantial, rewarding players who have committed to diversifying their collections across multiple categories. This is where the Index starts to feel genuinely transformative, as the percentage increases compound on your base stats and equipment bonuses. The mid-game milestones are where most dedicated players spend the bulk of their Index farming time, as each new entry brings you closer to the maximum possible buffs. The gap between 100 entries and 150 entries alone grants enough crit chance and damage to meaningfully shift your combat performance in challenging content.
End Game Rewards (155 to 200 Entries)
The final stretch from 155 to 200 entries delivers the most dramatic stat jumps in the entire milestone system. Each tier in the end-game range provides larger percentage increases than the equivalent early-game tier, recognizing the significant time and effort investment required to reach these heights. The difference between 175 entries and 200 entries, for example, can represent a noticeable shift in your ability to farm high-level bosses and clear difficult content. Players who push to maximum completion are rewarded with the most powerful version of every stat buff the Index offers.
Maximum Buff Summary
At the full 200 entries, your Sailor Piece Index provides the following permanent maximum buffs: +22.5% Damage, +25% Luck, +22.5% Crit Damage, +3.5% Crit Chance, and +15% HP. These five stats combine to create a character that is substantially more effective in every aspect of gameplay, from solo farming to group content and leaderboard competition. Because these are percentage-based permanent buffs, they will continue providing value regardless of what other gear or upgrades you acquire throughout your Sailor Piece career.
How Items Register in the Index
Understanding exactly how and when items count toward your Index total is crucial for efficient progression tracking and avoiding confusion about your actual entry count. The registration process is designed to be seamless, but there are some important details worth knowing.
Automatic Registration Process
Items are registered in the Sailor Piece Index automatically the moment you obtain them. There is no need to visit an NPC, open a menu, or perform any additional action for the item to count toward your total. When you pick up an item, complete a crate opening, unlock a new race, join a clan, or earn a title, the system immediately evaluates whether that item qualifies for Index tracking and updates your entry count accordingly. This automatic process means you cannot lose progress by forgetting to register items, but it also means you should verify your count after any significant acquisition session.
Verifying Your Index Progress
While the system is automatic, it is still wise to verify your Index progress regularly, especially when you suspect you should have earned a new entry but notice your count has not changed. You can check your current Index status by visiting either Index NPC location and reviewing your category breakdown. This interface shows you exactly how many entries you have in each of the 11 categories and which specific items you have unlocked. If you believe an item should have counted but it is not showing in your Index, try obtaining the item again or relogging to force a sync update.
Fastest Way to Complete the Index
Reaching 200 entries in the Sailor Piece Index requires a strategic approach, especially if you want to maximize your progress per hour of gameplay. While you will eventually naturally collect many items through regular play, using a focused strategy can significantly accelerate your timeline to maximum buffs.
Optimal Category Order
Not all categories are created equal when it comes to entry density and acquisition speed. Titles, Traits, and Races tend to offer the most entries relative to the time investment required, making them excellent early priorities. Cosmetics and Auras can also be acquired relatively quickly through crate openings and event participation. Swords and Melees require more targeted farming but are still accessible within reasonable timeframes. Relics and Bloodlines typically demand the highest effort per entry, so focusing on these categories later in your Index journey is often more efficient.
Reroll Strategy for Quick Gains
The reroll system in Sailor Piece allows you to reset your character progress and start fresh with different initial item distributions. This can be an effective strategy for rapidly building your Index because each reroll gives you a fresh opportunity to collect items you may have missed in previous runs. When using the reroll strategy, plan your new run to prioritize different categories than your previous attempt, and focus on unlocking as many distinct entries as possible before rerolling again. This approach is particularly effective for categories like Races, Clans, and Titles that reset cleanly with each new character.
Boss Grinding vs Crate Opening
Two of the primary methods for obtaining Index-eligible items are boss grinding and crate opening. Boss grinding involves repeatedly defeating high-level bosses that have chances to drop rare weapons, relics, and bloodlines. This method is time-intensive but predictable, allowing you to target specific categories you are missing. Crate opening, on the other hand, relies on randomness but can quickly grant access to dozens of items across multiple categories in a single session. A balanced approach that combines regular boss farming with strategic crate purchases tends to provide the best overall Index growth rate for most players.
Swords and Melees Worth Prioritizing
Given that Swords and Melees represent two of the largest weapon categories in the Sailor Piece Index, knowing which specific items to prioritize can save you hours of inefficient farming. While every item ultimately contributes the same +1 to your entry count, some items are significantly easier or faster to obtain than others.
High-Value Swords
Focus on swords that can be obtained through repeatable boss drops or quest completions rather than limited-time events or extremely rare spawn rates. Early-game swords that are gated behind straightforward boss fights should be your first targets, as these provide quick entry gains with minimal time investment. As you progress, shift your attention to mid-tier swords that offer reasonable drop rates from accessible content. Avoid spending excessive time farming ultra-rare swords that may only appear once every dozens of attempts unless you are specifically close to completing the swords category.
High-Value Melees
Melees are often faster to acquire than swords because their rarity floor tends to be lower. Prioritize melee weapons that drop from common and uncommon sources, as these can be collected in bulk during normal gameplay sessions. Many melee items can also be obtained through the reroll strategy mentioned earlier, making them particularly efficient for players who want to cycle through multiple characters quickly. Focus on obtaining one of each melee type before returning to hunt for rarer variants.
Items That Do NOT Count
Several item types are explicitly excluded from the Sailor Piece Index, and spending time farming these items is a common mistake among players who do not read the fine print. Leaderboard rewards, including top-rank titles and exclusive items granted for seasonal rankings, do not count toward your Index total. Similarly, guild titles earned through guild contribution systems are typically excluded from the Index, even though regular account-bound titles do count. Always verify that an item is Index-eligible before committing significant farming time to it.
Limited Items vs Regular Items
The Sailor Piece Index distinguishes between limited event items and regular permanently available items, and understanding this distinction is critical for planning your long-term Index completion strategy. This split affects both your acquisition approach and the timeline for completing certain categories.
Event-Exclusive Items
Event-exclusive items are limited-time offerings that can only be obtained during specific seasonal events or promotional periods. These items often come with unique visual designs or special animations that set them apart from regular catalog items. In the Index, event items are tracked separately from regular items, but they contribute the same +1 entry value once acquired. The challenge with event items is that missing their acquisition window may mean waiting months or even longer for a re-run, making them the primary obstacle for players pursuing true 100% Index completion.
What Happens When Limited Events End
When a limited event concludes, its exclusive items typically become unavailable for new players to obtain, though players who already own them retain them permanently. In the context of the Sailor Piece Index, items you acquired during past events remain counted toward your entry total even after the event ends. This means early players who participated in every event have a natural advantage in Index completion that newer players may never fully close. If you are a newer player, focus on maximizing your regular item collection and participate in every available event to gradually chip away at the limited item gap.
Title Grinding Tips
Titles represent one of the most entry-dense categories in the Sailor Piece Index, with dozens of distinct titles available across various difficulty tiers. Efficient title grinding can rapidly boost your entry count, making it an attractive category for players looking to accelerate their milestone progress.
Fastest Title Methods
The fastest titles to obtain are typically those tied to simple repeatable actions, such as reaching specific level milestones, defeating a certain number of enemies, or spending time in particular game modes. These titles can often be earned in a single extended play session by focusing your activity toward the specific requirement. Achievement-based titles that require boss defeats or rare accomplishments take longer but still provide a clear farming path. Create a checklist of easy titles and work through them systematically during your regular gameplay sessions to build your Index without dedicated grinding time.
Titles That Require Real Money
Some titles in Sailor Piece are tied to paid content, such as game passes, premium memberships, or special promotional purchases. These titles are flagged in the Index system, and while they do contribute to your entry count if you have obtained them, they should not be treated as part of your free-to-play farming strategy. If you are operating on a budget, prioritize the extensive array of free titles available through gameplay achievements and time investment before considering any paid options. For players willing to spend, however, these premium titles can be a quick way to add several entries to your Index with minimal gameplay effort.
