Sailor Piece's Moon Update, which landed on March 31, 2026, introduced the Power System — a trait-based mechanic that layers permanent passive stat boosts on top of your existing sword, fighting style, race, and clan setup. Only one Power trait can be active at a time, but the bonuses it provides apply globally to your build, covering Damage, HP, Crit Chance, Crit Damage, and in some cases Luck or boss-specific damage multipliers. It is strictly a late-game feature, gated behind a steep level and currency requirement.
Quick answer: Reach Level 11,500, collect 5,500 Gems, then talk to the Power Master NPC on Lawless Island and confirm the unlock prompt. After that, spend Power Shards at the same NPC to reroll for one of 17 Power traits.
How to Unlock the Power System
Two hard requirements stand between you and the Power System. You need to be at least Level 11,500 and have 5,500 Gems in your inventory. Gems can be accumulated through boss runs or by redeeming active Sailor Piece codes, so stock up before making the trip.
Step 1: Travel to Lawless Island using the map portals. The island is accessible once you are high enough level to reach late-game zones.
Step 2: Find the Power Master NPC. He stands directly opposite the Arena Fighters NPCs on Lawless Island.
Step 3: Interact with the Power Master. A small confirmation window will appear at the top of your screen. Select "Yes" to permanently unlock the Power System.
Once unlocked, the Power Master NPC doubles as your reroll hub. You do not need to visit any other island to use the system going forward. You will know the unlock succeeded when the NPC's dialogue shifts to show the Reroll option instead of the unlock prompt.
Power Shards — The Reroll Currency
Every reroll at the Power Master costs Power Shards, a Legendary-rarity item that drops from any enemy NPC in the game, including regular mobs, mini-bosses, and world bosses. Drop rates are low across the board, but higher-difficulty enemies yield better odds. The most efficient farming spots are Ninja Island and Lawless Island, where mob levels are high enough that each kill has a meaningful chance of producing a shard.
Party play also helps. Shared kills still award Power Shards to each group member, so running with others effectively multiplies your farming output without splitting rewards.
How Rerolling Works
Interact with the Power Master on Lawless Island and hit the Reroll button. Each reroll consumes Power Shards and returns a random Power trait drawn from a fixed probability table. You can only hold one active Power trait at a time — rerolling replaces whatever you currently have.
The system includes a filter feature for auto-rerolls. You can exclude specific rarities you do not want, which prevents the auto-reroller from stopping on Common or Uncommon results and burning through your shard supply for nothing useful. There is no way to directly select a specific trait; the outcome is always random within the allowed rarity pool.
Reroll Drop Rates by Rarity
| Rarity | Drop Rate | Number of Traits |
|---|---|---|
| Common | 50% | 3 |
| Uncommon | 28.75% | 3 |
| Rare | 15% | 3 |
| Epic | 5% | 3 |
| Legendary | 1% | 3 |
| Mythical | 0.2% | 2 |
Half of all rerolls will land on a Common trait, and roughly four out of five will be Uncommon or below. Filtering out those lower tiers during auto-rerolls is essential if you are hunting Legendary or Mythical results.

|---|---|---|---|---|---|
| Cursebrand | 18–30% | 15–30% | 2–4% | 6–12% | After hitting an NPC, it takes 10–15% increased damage; stacks with up to 2 players |

Which Power Traits Are Worth Keeping
Colossus is the strongest overall Power trait. Its raw stat ranges are the highest in the game, and the combination of a Luck bonus with a dedicated boss-damage multiplier makes it ideal for both farming drops and clearing endgame bosses. Cursebrand is the other Mythical option and excels in group play — its stacking debuff on NPCs means two players running Cursebrand can amplify each other's damage significantly.
At the Legendary tier, Abyssal and Eternal are the most practical targets while you continue chasing Mythicals. Abyssal leans toward raw offensive output with up to 24% Damage and 3% Crit Chance, while Eternal favors survivability with up to 28% HP alongside strong Crit stats. Apex is slightly weaker offensively but provides a Luck bonus that can speed up item farming.
Verification and Common Issues
After unlocking the Power System, you can confirm it is active by returning to the Power Master NPC. His dialogue should now show the Reroll interface rather than the unlock prompt. Your currently equipped Power trait and its stat values are visible in the same menu.
If the unlock prompt does not appear, double-check that you have reached Level 11,500 and that you have exactly 5,500 Gems or more. Both conditions must be met simultaneously. The NPC will not display the option otherwise, and there is no partial-unlock state.
The Power System works independently from the Spec Passive system. While Spec Passives apply to individual specialization slots, Power traits affect your entire build universally. Both systems stack, so a well-rolled Power trait on top of strong Spec Passives creates a compounding effect on your overall damage and survivability.
