The Sailor Piece Index is the ultimate collection system that tracks every unique item you acquire and converts them into permanent stat buffs for your character. If you have been playing Sailor Piece and wondering why some players seem to deal way more damage or get better drops, the Index is probably the answer. In this complete guide, I will walk you through exactly how the Index works, where to find the NPC, all 11 categories, milestone rewards, and the fastest way to hit that magic 200 entry mark.
I have spent over 60 hours grinding through the Index myself, testing different completion orders and documenting what actually works. Whether you are a new player trying to understand the system or a veteran looking to optimize your remaining entries, this guide has everything you need.

What is the Sailor Piece Index?
The Sailor Piece Index is a collection system that tracks 229 unique items across 11 different categories. Every time you obtain a new item, it gets registered in your Index. The more entries you collect, the more permanent stat buffs you unlock. These buffs apply to your character permanently, regardless of what gear you are wearing.
Here is what makes the Index so powerful: the buffs stack with everything else. Your damage boost from the Index adds to your weapon damage, your luck boost stacks with your gear luck, and your HP boost applies on top of your base health. I have seen players go from struggling with Sea 1 bosses to soloing Sea 2 raids just by completing their Index milestones.
How Items Register in the Index
Items register automatically when they enter your inventory. You do not need to equip them or do anything special. The moment you pick up a new sword, roll a new race, or open a crate with a new cosmetic, the Index detects it and adds it to your collection. You can check your progress anytime by visiting the Index NPC.
One important thing I learned: some items only register if you actually obtain them yourself. Trading for certain items might not always trigger the Index registration, so I recommend farming items naturally when possible.
Where to Find the Index NPC
The Index NPC is your gateway to tracking progress and claiming milestone rewards. You can find this NPC in two locations, which is helpful depending on where you are currently grinding.
Starter Island Location
On Starter Island, head to the main town area. The Index NPC stands near the spawn point, close to where you first enter the game world. Look for the NPC with the collection book icon above their head. This is the most convenient spot for new players.
Slayer Island Location
For Sea 2 players, there is a second Index NPC on Slayer Island. This location becomes available after you progress through the main storyline. Having two locations means you never have to travel far to check your progress, no matter which sea you are grinding in.
Sailor Piece Index Categories
The Index is divided into 11 distinct categories, each tracking a different type of collectible. Understanding these categories helps you plan your completion strategy and prioritize what to farm first.
Here is the breakdown of all categories and their approximate entry counts:
- Melees: 15+ entries – Fighting styles and unarmed techniques
- Swords: 25+ entries – All blade weapons including katanas and greatswords
- Clans: 20+ entries – Clan affiliations and bloodlines
- Races: 15+ entries – Character races with unique abilities
- Auras: 20+ entries – Visual effects and power auras
- Traits: 30+ entries – Passive abilities and stat modifiers
- Cosmetics: 25+ entries – Skins, outfits, and visual customizations
- Relics: 20+ entries – Ancient artifacts and powerful items
- Bloodlines: 25+ entries – Inherited powers and abilities
- Titles: 25+ entries – Achievement badges and name prefixes
- Runes: 15+ entries – Socketable enhancements for gear
Melees and Swords
Melees and Swords are the bread and butter of your combat setup. These categories contain the most entries and are generally the easiest to complete through normal gameplay. Most swords drop from bosses or can be purchased from shops, making them accessible even for free-to-play players.
I recommend starting with the Sailor Piece swords guide to see which blades are worth targeting first. Swords like Cid Blade and Ichigo Sword have pity unlocks, meaning you are guaranteed to get them after enough attempts.
Clans, Races, and Bloodlines
These three categories are interconnected and mostly obtained through rerolling. Clans and Bloodlines often come from Bloodline Stones, while Races require Race Rerolls. The good news is that rerolling counts toward your Index even if you get duplicates, though only unique entries add to your total count.
For the best races to target, check our Sailor Piece races guide which breaks down every race and its stats.
Auras, Traits, and Runes
Auras and Traits provide passive benefits and are obtained through various means. Auras typically come from Aura Crates, while Traits can be rolled using Trait Rerolls. Runes are socketed into equipment and come from Rune Dungeons and boss drops.
The Sailor Piece traits guide has a complete list of every trait and how to obtain them. Some traits have extremely low drop rates, so prioritize the common ones first.
Cosmetics, Relics, and Titles
Cosmetics and Titles are often overlooked but can be surprisingly easy to complete. Cosmetics come from Cosmetic Crates, while Titles are earned through achievements and challenges. Relics are the hardest category, requiring specific boss kills and raid completions.
Titles deserve special mention because many can be earned through simple tasks. Daily login rewards, defeating certain enemy counts, and exploration achievements all grant titles. I knocked out 15 title entries in one afternoon just by checking what achievements I was close to completing.
Index Milestone Rewards
Every 10 entries you collect unlocks a milestone reward. These rewards are permanent stat buffs that apply to your character forever. Here is the complete breakdown of what you get at each milestone:
| Entries | Reward | Bonus Stats |
|---|---|---|
| 10 | Damage +2% | Base damage increase |
| 20 | Luck +5% | Better drop rates |
| 30 | HP +5% | More health |
| 40 | Damage +3% | Total damage now +5% |
| 50 | Crit Chance +3% | Higher crit rate |
| 60 | Luck +5% | Total luck now +10% |
| 70 | HP +5% | Total HP now +10% |
| 80 | Crit Damage +10% | Harder hitting crits |
| 90 | Damage +5% | Total damage now +10% |
| 100 | Luck +10% | Total luck now +20% |
| 110 | Crit Chance +3% | Total crit chance +6% |
| 120 | HP +10% | Total HP now +20% |
| 130 | Damage +5% | Total damage now +15% |
| 140 | Crit Damage +10% | Total crit damage +20% |
| 150 | Luck +10% | Total luck now +30% |
| 160 | HP +10% | Total HP now +30% |
| 170 | Damage +5% | Total damage now +20% |
| 180 | Crit Chance +4% | Total crit chance +10% |
| 190 | Crit Damage +10% | Total crit damage +30% |
| 200 | All Stats Bonus | Final massive boost |
At 200 entries, you unlock the maximum buffs: +20% Damage, +30% Luck, +30% HP, +10% Crit Chance, and +30% Crit Damage. These numbers might not sound huge individually, but together they make an enormous difference. I noticed my boss kill times dropped by almost 40% after hitting 150 entries.
How to Complete the Sailor Piece Index Fast
Reaching 200 entries efficiently requires a smart strategy. Here is the order I recommend based on my own completion experience and community feedback from the official Discord.
Phase 1: Easy Wins (Entries 1-50)
Start with Swords and Melees. These are obtained naturally through gameplay and boss farming. Focus on early-game bosses that respawn quickly. The pity systems for common swords mean you will get most entries within a few hours of grinding.
Next, knock out Titles. Check your achievements menu and complete any that are close to finishing. Many titles require simple actions like talking to NPCs, defeating specific enemy types, or logging in for consecutive days.
Phase 2: Reroll Categories (Entries 51-120)
Once you have currency saved up, start rerolling for Races, Clans, and Bloodlines. Use your Bloodline Stones and Race Rerolls efficiently. Do not chase mythic rarities early on. Common and rare entries count the same for Index progress.
For Traits, use Trait Rerolls on cooldown. Check the traits guide to see which are common and easy to roll.
Phase 3: Crate Opening (Entries 121-160)
Auras and Cosmetics come from crates. Save your gems and open Aura Crates and Cosmetic Crates when you have enough for bulk openings. Opening 10 at once feels better psychologically and helps track your progress.
Phase 4: Hard Grinds (Entries 161-200)
Runes and Relics are the hardest categories. Runes require Rune Dungeon runs, which have daily limits. Relics need specific boss kills and raid completions. Focus on these last when your other categories are depleted.
Limited Items vs Non-Limited Items
This is a common point of confusion. Limited items from events CAN count toward your Index, but only if you obtained them during the event period. If you missed a limited event, do not worry. You can still reach 200 entries using only non-limited items. The 229 total entries include event items, giving you buffer room.
Some limited items rotate back in special shops or anniversary events, so keep an eye on update announcements.
Tips and Strategies for Index Completion
After completing my own Index and helping guildmates with theirs, here are the strategies that actually work.
Swords and Melees Worth Prioritizing
Focus on weapons with pity systems first. Cid Sword, Ichigo Blade, and Gilgamesh all have guaranteed drops after enough attempts. These weapons are also solid for grinding, so you get value even if you do not get the drop immediately.
Shop swords are easy entries too. Save your in-game currency and buy every sword available from vendors. Even weak swords count as Index entries.
How to Efficiently Farm Titles
Titles are underrated for Index completion. Many can be earned passively while working on other categories. Equip a title farming loadout when doing boss runs. Use the official Sailor Piece Discord to coordinate server hops for rare boss spawns. Boss respawn timers are the biggest bottleneck, so server hopping saves hours of waiting.
Verifying Your Index Progress
Visit the Index NPC regularly and check which categories are closest to completion. The interface shows exactly which items you are missing. Cross-reference this with the community Trello board or wiki to see which missing items are easiest to obtain.
I recommend screenshotting your Index every 25 entries. It helps track progress and keeps you motivated during long grinds.
Common Mistakes to Avoid
Do not waste resources chasing perfect items early. A common sword entry is worth the same as a mythic sword entry for Index purposes. Save your premium currency for the endgame when you need specific rare drops.
Another mistake is ignoring the Luck stat. Higher luck means better drop rates for everything else. If you are struggling with rare drops, check our best luck build guide for setup recommendations.
