Artifacts in Sailor Piece are armor-style equipment pieces that provide significant stat boosts — damage, crit chance, crit damage, defense, lifesteal, and more. They're tucked away in a menu that's easy to overlook, but they represent one of the strongest ways to scale your character for end-game content. You can equip up to four pieces at once (Helmet, Gloves, Body, and Boots), and matching pieces from the same set unlock additional bonuses.
Quick answer: To enable Artifact drops, reach Level 2,500 with 500,000 Money and 500 Gems, then talk to the Artifacts NPC on Snow Island or open the Artifacts tab in your Inventory.
Sailor Piece Artifact Unlock Requirements
Artifacts don't drop until you explicitly activate the system. Three conditions must all be met before you can interact with the Artifacts NPC on Snow Island or toggle drops through the Inventory menu.
| Requirement | Amount |
|---|---|
| Player Level | 2,500 |
| Money | 500,000 |
| Gems | 500 |
Once all three are satisfied, head to Snow Island and speak with the Artifacts NPC. The Artifacts interface will open, and from that point forward mobs, mini-bosses, and World Bosses across the game can drop artifact pieces. You can also access your collected pieces through the Artifacts section of your inventory menu at any time.
All Artifact Sets and Drop Locations
Five distinct artifact sets exist in Sailor Piece. Each set drops from specific islands, though World Bosses have a small chance to drop pieces from any set. Farming the correct island is the most efficient way to target the set you want.
| Artifact Set | Primary Drop Locations |
|---|---|
| Ashen Chronicles | Jungle Island, Starter Island (mobs and mini-bosses) |
| Void Artifact | All World Bosses exclusively |
| Crownless | Desert Island, Snow Island (mobs and mini-bosses) |
| Black Horizon | Shibuya Station, Hueco Mundo (mobs and mini-bosses) |
| Celestial Rupture | Shinjuku Island, Slime Island, Soul Society, Academy Island, Judgement Island (mobs and mini-bosses) |
World Bosses also have a small chance to drop pieces from the Ashen Chronicles, Crownless, Black Horizon, and Celestial Rupture sets, making boss farming a viable supplementary strategy.
Artifact Piece Types, Main Stats, and Sub Stats
Every artifact piece buffs one Main Stat and one Sub Stat. The Main Stat is locked to the piece type, while the Sub Stat is drawn from a shared pool. Importantly, the Main Stat and Sub Stat on a single piece cannot be the same — if your Boots roll Damage as a Main Stat, Damage will not appear as the Sub Stat on that piece.
| Piece | Possible Main Stats |
|---|---|
| Helmet | Defense or Flat Defense |
| Gloves | Damage only |
| Body | Any stat |
| Boots | Damage, Defense, Flat Defense, or Damage Reduction |
The Sub Stat on any piece can be one of eight options. Higher rarity artifacts roll higher values for both Main and Sub Stats. The ranges below represent the maximum Sub Stat values across all rarities.
| Sub Stat | Range |
|---|---|
| Crit Chance | 6% – 10.5% |
| Crit Damage | 11% – 18% |
| Damage | 4% – 9% |
| Defense | 8% – 15% |
| Flat Defense | 20,000 – 50,000 |
| Damage Reduction | 2% – 4% |
| Lifesteal | 0.5% – 1.5% |
| HP Regen | 7.5% – 15% |
Set Bonuses in Sailor Piece
Equipping multiple pieces from the same artifact set activates set effects that stack additional stat buffs on top of the individual piece stats. Two pieces from the same set trigger the first tier of bonuses, while a full four-piece matching set maxes out the set effect. You can check the exact bonus values for each set inside the Artifacts menu when you hover over or select a piece.
How to Upgrade Artifacts With Dust
Each artifact piece can be leveled from 0 to 15, and upgrading increases the Main Stat value while also unlocking Sub Stats along the way. The total cost to fully max a single piece is 287 Dust.
Step 1: Open your Artifacts menu and click on the piece you want to upgrade. A detail panel appears on the right side of the screen.
Step 2: Click the Upgrade button next to the Equip/Unequip button. A pop-up will appear with a "Use Dust" option.
Step 3: Use the "+" sign to add Dust, then confirm the upgrade. You can upgrade pieces one at a time or batch-upgrade up to 50 artifacts simultaneously if you have enough Dust.
How to Get Dust in Sailor Piece
The sole source of Dust is deleting unwanted artifacts. Select a piece you no longer need, click the trash button next to the Equip/Unequip button, and confirm the deletion. Legendary artifacts yield the most Dust at 24 per piece when deleted.
For bulk cleanup, use the trash option under Mass Options. You can also configure Auto Delete Settings to automatically destroy artifacts of a specific rarity while you're actively farming, which saves time and steadily builds your Dust reserves in the background.
One important detail about selling upgraded artifacts: you only recover roughly 33.8% of the Dust invested. A fully maxed Legendary piece that cost 287 Dust to upgrade returns 96 Dust when deleted. Plan your upgrades carefully to avoid wasting resources on pieces you'll eventually replace.
Artifact Rarities and How to Improve Drop Rates
Artifacts come in four rarities: Common, Rare, Epic, and Legendary. When you first unlock the system, roughly 90% of your drops will be Common. The path to better drops runs through the Artifact Milestone system.
On Snow Island, right next to the Artifacts NPC, you'll find the Artifact Milestone NPC. Speaking with this NPC opens an Artifact Collection Progress menu that tracks your Data Rank from Level 0 to Level 40. Every artifact you collect — regardless of rarity — grants 1 Data Rank EXP. As your Data Rank increases, the probability of higher-rarity drops improves across all sources.
Artifact Milestone Rewards
Beyond improved drop rates, each Data Rank level awards specific rewards when claimed. Visit the Artifact Milestone NPC on Snow Island, select the levels you've reached, and collect your prizes. Rewards include Race Rerolls, Trait Rerolls, Haki Color Rerolls, and other exclusive benefits that are difficult or impossible to obtain elsewhere.
Since every single artifact you pick up counts as 1 EXP toward your Data Rank, there's no reason to skip artifact farming even if you're already happy with your equipped set. The milestone rewards alone make continued collection worthwhile, and the improved rarity odds compound over time to make your farming sessions progressively more productive.
Frequently Asked Questions
How many artifacts can I equip at once?
You can equip exactly four — one Helmet, one pair of Gloves, one Body piece, and one pair of Boots.
Can I get set bonuses with just two matching pieces?
Yes. Equipping two pieces from the same set activates the first tier of set effects. Four matching pieces unlock the full bonus.
What's the fastest way to accumulate Dust?
Enable Auto Delete for Common artifacts while farming. This passively converts low-value drops into Dust without interrupting your grind.
Do World Bosses drop all artifact sets?
World Bosses can drop pieces from every set, though the Void Artifact set drops exclusively from World Bosses. For other sets, farming the designated islands is more reliable.
Artifacts slot neatly into Sailor Piece's broader late-game progression alongside Runes, Blessings, and Cosmetics. Prioritize unlocking the system as soon as you hit Level 2,500, farm the islands that match the set you need, and funnel unwanted drops into Dust to keep your best pieces leveling up. The milestone system rewards persistence, so the more you farm, the better your drops — and your free rerolls — become over time.
