Artifacts in Sailor Piece function as equippable gear pieces that buff your Damage, Critical Chance, Critical Damage, Defense, and other combat stats. They sit alongside Cosmetics, Auras, and Blessings as a separate progression layer, but the system has its own unlock requirements, a dedicated upgrade currency called Dust, and a milestone mechanic that controls how often you receive high-rarity drops. If you're pushing into late-game content, Artifacts are one of the most impactful stat sources you can invest in.
Quick answer: Reach Level 2,500, then pay 500,000 Money and 500 Gems to the Artifacts NPC on Snow Island. Once enabled, all mobs, mini-bosses, and World Bosses can drop Artifacts.
Unlock Requirements for Artifacts
Artifact drops are disabled by default. You won't see a single piece until you manually activate the system. Head to Snow Island and walk past the igloos toward a pair of NPCs standing near some trees — the Artifacts NPC and the Artifact Milestones NPC.
Step 1: Reach Level 2,500. There is no shortcut around this prerequisite; the Artifacts NPC will not interact with you below that level.
Step 2: Travel to Snow Island through the portal and locate the Artifacts NPC near the igloos.
Step 3: Interact with the NPC by pressing E. You'll be prompted to pay 500,000 Money and 500 Gems. Once you confirm, the Artifacts menu becomes available in your Inventory, and enemies across the entire game will begin dropping Artifact pieces.
All Artifact Sets and Drop Locations
Every Artifact belongs to one of five sets. Each set drops from specific islands, though World Bosses have a small chance to drop pieces from any set. Matching set pieces together activates bonus stats when you equip two or four pieces from the same set.
| Artifact Set | Drop Locations |
|---|---|
| Ashen Chronicles | Mobs and Mini-bosses at Jungle Island and Starter Island; small chance from World Bosses |
| Void Artifact | All World Bosses |
| Crownless | Mobs and Mini-bosses at Desert Island and Snow Island; small chance from World Bosses |
| Black Horizon | Mobs and Mini-bosses at Shibuya Station and Hueco Mundo; small chance from World Bosses |
| Celestial Rupture | Mobs and Mini-bosses at Shinjuku Island, Slime Island, Soul Society, Academy Island, and Judgement Island; small chance from World Bosses |
If you're targeting a specific set, farm the corresponding island mobs rather than relying on World Boss drops. The Void Artifact Set is the exception — it only comes from World Bosses.
Artifact Pieces, Main Stats, and Sub Stats
Each set contains four piece types: Helmet, Gloves, Body, and Boots. You can equip one of each type simultaneously for a maximum of four equipped Artifacts. Every piece rolls one Main Stat and one Sub Stat, and the Main Stat pool differs depending on the piece type.
| Piece | Possible Main Stats | Possible Sub Stats (shared across all pieces) |
|---|---|---|
| Helmet | Defense, Flat Defense | Crit Chance, Crit Damage, Damage, Defense, Flat Defense, Damage Reduction, Lifesteal, HP Regeneration |
| Gloves | Damage, Crit Chance, Crit Damage | |
| Body | Any stat in the game (including HP, Lifesteal, etc.) | |
| Boots | Damage, Damage Reduction, Defense, Flat Defense |
One important rule: the Main Stat and Sub Stat on a single piece will never be the same. If your Boots roll Damage as the Main Stat, Damage cannot appear as the Sub Stat on that same piece.
Stat values scale with rarity. Common pieces offer the lowest numbers, while Legendary pieces provide the highest. For PvP and PvE alike, prioritizing Damage, Crit Chance, and Crit Damage on your Gloves and Body pieces tends to yield the biggest combat improvements.
How to Upgrade Artifacts with Dust
Dust is the sole currency for leveling up Artifacts, and the only way to get it is by deleting Artifacts you don't need. There's no shop, no code redemption, and no boss that drops Dust directly — it comes exclusively from scrapping spare pieces.
Step 1: Open the Artifacts menu (either through the Artifacts NPC or the Inventory tab). Select the pieces you want to destroy and press the red trashcan icon in the bottom-right corner. Each deleted piece awards Dust, with Legendary pieces giving the most at 24 Dust each.
Step 2: Select the Artifact you want to upgrade and click the Upgrade button next to the Equip button. A pop-up will appear with a "Use Dust" option. Click the "+" sign to allocate Dust, then confirm the upgrade.
The maximum level for any Artifact is Level 15, which costs a total of 287 Dust from Level 0. You can upgrade pieces one at a time or batch-upgrade up to 50 simultaneously if you have enough Dust stockpiled.
Artifact Milestones and Increasing Rarity Drop Rates
When you first enable Artifacts, roughly 90% of your drops will be Common rarity. That ratio improves as you level up the Artifact Milestones system, which tracks how many total Artifacts you've collected.
The Artifact Milestones NPC stands right next to the Artifacts NPC on Snow Island. Interacting with this NPC opens the Artifact Collection Progress menu, which shows your current level and the rewards for each tier. You earn 1 Data Rank EXP for every Artifact you pick up, regardless of rarity or set.
The milestone system currently goes up to Level 40. As you climb through the levels, the probability of receiving Rare, Epic, and Legendary Artifacts increases steadily. Milestone rewards also include Race Rerolls, Trait Rerolls, and Haki Color Rerolls at various thresholds.
The practical takeaway is straightforward: farm as many Artifacts as possible early on, even if most of them are Common. Delete the ones you don't need for Dust, and let the milestone progression naturally shift your drops toward higher rarities over time.
Artifact Rarities
| Rarity | Stat Values | Dust When Deleted |
|---|---|---|
| Common | Lowest | Low |
| Rare | Moderate | Moderate |
| Epic | High | High |
| Legendary | Highest | 24 |
Even Common pieces serve a purpose in the early grind. Equipping any four-piece matching set is better than leaving slots empty, and every piece you collect feeds into your milestone progression.
Set Bonuses
Equipping two pieces from the same set activates a two-piece set bonus, and equipping all four pieces from one set activates a stronger four-piece bonus. The exact stat buffs for each set bonus are visible in the Artifacts menu when you hover over or select a set. Mixing and matching is possible — you could run a two-piece bonus from one set and a two-piece bonus from another — but a full four-piece set generally provides the most concentrated stat boost.
Frequently Asked Questions
How many Artifacts can I equip at once?
Four — one Helmet, one pair of Gloves, one Body piece, and one pair of Boots.
How much Dust does it take to max an Artifact?
287 Dust total to go from Level 0 to Level 15.
Can I trade Dust with other players?
No. Dust is non-tradeable and only appears in the upgrade menu.
Do World Bosses drop all sets?
World Bosses have a small chance to drop pieces from any set, but the Void Artifact Set drops exclusively from World Bosses.
Artifacts represent one of the biggest stat jumps available in Sailor Piece's late game. The grind to shift your drops from mostly Common to consistently Epic and Legendary takes time, but the payoff in Damage, Crit Chance, and survivability stats is substantial enough to reshape how you approach endgame bosses and PvP encounters. Focus on reaching Level 2,500, unlock the system as soon as you can afford the 500,000 Money and 500 Gems, and start stacking milestone levels immediately.
