Sailor Piece's islands are staffed: dozens of masters, sellers, trainers, and keepers, each holding exactly one service, from artifact unlocks to stat rerolls to weapon shops. Knowing who stands where is the difference between playing the game and commuting through it.

The service directory
The roster splits into recognizable jobs. Masters run progression systems: powers, passives, artifacts, ascension. Sellers and exchangers turn boss drops into weapons. Trainers unlock combat systems like haki, and the reroll crowd, race, trait, stat, clan, spends your shards and gems. Locations repeat across seas, with key NPCs mirrored on the Sea 2 islands.
- Learn the reroll NPCs first; they are the ones you will visit hundreds of times.
- Boss sellers stand near their boss's island, so weapon shopping is co-located with the grind that funds it.
- When a system seems locked, the answer is usually an NPC you have not met on an island you have not searched.
FAQ
Q.
Where is the Power Master?
Each NPC's card lists its island. Progression masters cluster on the main progression islands, with mirrors in Sea 2.
Q.
What do seller NPCs do?
They exchange boss drops and currency for that boss's weapons, standing near the content that drops their materials.
Q.
Why can't I find an NPC?
Several NPCs exist only in Sea 2 or inside specific dungeons; the location line on each card is the map answer.
