The Power System in Sailor Piece is a late-game mechanic that applies passive stat boosts to your entire build instead of a single weapon or fighting style. One Power trait stays active at a time, and its bonuses cover Damage, HP, Crit Chance, Crit Damage, and sometimes Luck or extra boss damage. It runs alongside Spec Passives, races, clans, and regular traits, so a strong roll stacks on top of everything you already have.
Quick answer: Reach Level 11,500 and hold at least 5,500 Gems, talk to the Power Master NPC on Lawless Island and select “Yes” to unlock the system, then spend Power Shards at the same NPC to reroll for one of the Power traits.
Power System unlock requirements in Sailor Piece
Two conditions gate the system, and both must be met at the same time. You need to be Level 11,500 or higher and have 5,500 Gems in your inventory. Gems come from boss runs, redeemable codes, and chests across the islands, so stock up before heading out. If either requirement is missing, the unlock option will not appear.
You know the unlock worked when the Power Master’s dialogue switches from the unlock prompt to the Reroll interface. Your active Power and its stat values also show up in that same menu. If the prompt never appears, recheck that you have hit Level 11,500 and that you are holding 5,500 Gems or more, since there is no partial-unlock state.
Power Shards and how rerolling works
Rerolling costs Power Shards, a Legendary-rarity item that only begins dropping after you unlock the system. Once active, shards can drop from any enemy NPC, including regular mobs, mini-bosses, and world bosses. Drop rates are low overall, but higher-level enemies give better odds, which makes Ninja Island and Lawless Island the most efficient farming spots.
You cannot pick a specific Power directly. Filters only narrow the rarity pool, so landing a Legendary or Mythical still comes down to repeated rolls. Stacking Luck from titles, accessories, runes, and your current Power also raises shard drop efficiency, and shared party kills award shards to every member.
Power reroll drop rates by rarity
Half of all rolls land on a Common trait, and roughly four out of five fall at Uncommon or below. Filtering out the bottom tiers is essential if you are chasing the top end.
| Rarity | Drop Rate |
|---|---|
| Common | 50% |
| Uncommon | 28.75% |
| Rare | 15% |
| Epic | 5% |
| Legendary | 1% |
| Mythical | 0.2% |
All Sailor Piece Power traits and stats
The system launched with 17 Power traits split across six rarities, and a new Mythical option, Subjugator, was added later. Higher rarities carry wider stat ranges and add bonuses like Crit, Luck, or boss damage on top of the base Damage and HP.
| Power | Rarity | Stats |
|---|---|---|
| Fierce | Common | 2–5% Damage, 3–6% HP |
| Solid | Common | 2–4% Damage, 4–8% HP |
| Tempered | Common | 3–5% Damage, 3–8% HP |
| Battleborn | Uncommon | 3–6% Damage, 5–10% HP |
| Empowered | Uncommon | 4–7% Damage, 4–9% HP |
| Resolute | Uncommon | 3–7% Damage, 6–12% HP |
| Wrathful | Rare | 5–10% Damage, 7–14% HP, 0.5–1.5% Crit Chance |
| Infernal | Rare | 6–12% Damage, 7–14% HP, 3–6% Crit Damage |
| Ironclad | Rare | 7–14% Damage, 8–18% HP |
| Reaper | Epic | 8–16% Damage, 10–18% HP, 0.5–1.5% Crit Chance, 2–4% Crit Damage |
| Titanborn | Epic | 7–14% Damage, 14–24% HP, 0.5–1.5% Crit Chance |
| Tempest | Epic | 9–18% Damage, 8–16% HP, 0.75–2% Crit Chance |
| Apex | Legendary | 10–20% Damage, 10–20% HP, 0.5–1.5% Crit Chance, 5–12.5% Luck |
| Abyssal | Legendary | 14–24% Damage, 10–20% HP, 1–3% Crit Chance, 4–8% Crit Damage |
| Eternal | Legendary | 13–22% Damage, 14–28% HP, 1–3% Crit Chance, 5–10% Crit Damage |
| Cursebrand | Mythical | 18–30% Damage, 15–30% HP, 2–4% Crit Chance, 6–12% Crit Damage, +10–15% damage after hitting an NPC, stacks with 2 players |
| Colossus | Mythical | 20–34% Damage, 20–35% HP, 1.5–3% Crit Chance, 5–10% Crit Damage, 7.5–15% Luck, +15–25% boss damage |
| Subjugator | Mythical | 24–40% Damage, 24–40% HP, 1.75–3.5% Crit Chance, 6.5–13% Crit Damage, 8.5–17.5% Luck, hit NPCs slowed by 20% for 5s (no stack) |
Best Powers to keep
Colossus has long been the standout Mythical, pairing the highest base stats with a Luck bonus and a dedicated boss-damage multiplier that helps with both farming and endgame clears. Cursebrand shines in group play, since its stacking debuff lets two players running it amplify each other’s damage. Subjugator pushes the stat ceiling even higher with a built-in 20% slow on hit, though it cannot stack.
While you hunt Mythicals, Legendary traits are the practical targets. Abyssal leans into raw offense with up to 24% Damage and 3% Crit Chance, Eternal favors survivability with up to 28% HP plus solid Crit stats, and Apex trades some damage for a Luck boost that speeds up item farming.
Treat Epic traits and below as temporary placeholders. The jump from Epic to Legendary is large, and the gap from Legendary to Mythical is larger still, so keep filtering Common and Uncommon out of your auto-rerolls to avoid wasting shards on traits you will immediately replace. The Power System works independently from Spec Passives, and because both stack, a strong Power on top of good Spec Passives compounds your overall damage and survivability.
