Sailor Piece Boss Farming Guide

Bosses are the beating heart of progression in Sailor Piece. They are the primary source of titles, accessories, crafting materials and rerolls — and if you trace almost any endgame goal backwards, it leads to farming a specific boss. With over 35 bosses in the game, the difference between an efficient grinder and a player stuck for days comes down entirely to understanding how the drop and pity systems work. This complete guide covers every boss type, the maths behind pity, the Luck mechanic, and the single golden rule that makes boss farming dramatically faster.

1Understand the Pity System

Every boss drop in Sailor Piece has two numbers attached: a drop rate and a pity counter. The drop rate is your per-kill chance — sometimes a brutal fraction of a percent. The pity counter is the safety net: it guarantees the drop once you reach a set number of kills, no matter how unlucky your streak. This means even a punishing 0.6% title is guaranteed eventually. Always look up a boss's pity number before you begin, because it tells you the absolute worst-case kill count and lets you plan your whole session around a known finish line.

2The Four Boss Types

• Timed bosses — respawn automatically every few minutes on islands like Sailor Island and Shibuya. The easiest and cheapest to farm early.
• Summonable bosses — spawned manually with keys or seals, plus Money and Gems. Worth it for their specific drops.
• World Bosses — huge shared-HP bosses in Sea 2 that reward every player who lands damage on them.
• Sea Beasts — roaming bosses found in the open water of Sea 2, dropping rare endgame materials.

3Every Boss & Its Stats

Here is the live boss table with HP, sea and spawn type for every boss in the game, pulled directly from our database. Use it to plan your farming route. And never forget the golden rule of boss farming: always target the boss that drops both the title AND the crafting materials for the weapon you want, so a single focused grind completes an entire weapon unlock at once.

4Building an Efficient Farm Route

1. 1

   Pick one target boss

   Pity counters are per-boss. Focusing a single boss drives its counter to the guarantee fastest.

2. 2

   Stack Luck before you start

   Raise Luck from stats, race, clan and Luck relics — it shortens the grind to pity.

3. 3

   Farm to the pity number

   Keep killing until either the drop lands or you hit the guaranteed pity threshold.

4. 4

   Claim title, materials and tickets together

   One boss grind gives the title, the weapon materials and Boss Tickets — three goals from one farm.
