Updated on May 20, 2026: Added information about all of the World Bosses up to and including the new Black Reaper Boss from the Sailor Piece Ghoul update. Black Reaper is a powerful boss which you can summon by farming Reaper Keys on Isolation Island in Sailor Piece.
There are two different types of bosses in Sailor Piece- Mob Bosses and World Bosses. Mob Bosses are the mini-bosses that you can grind for Money and EXP. World Bosses, on the other hand, are stronger and will drop rare materials when defeated. In this Sailor Piece Boss guide, you’ll find a full list of all the bosses, their spawn locations, and the items/materials they will drop upon defeat. So, if you’re looking for information on a certain boss, this guide will help.
Where to Find All Sailor Piece Bosses - Locations, Drops, & How to Spawn
As you progress through Sailor Piece, your focus will shift from regular Mob bosses, to World Bosses as well as Summonable Bosses. In order to help you out, especially as a beginner, we are showing you exactly where you can find Sailor Piece Bosses, what they drop, and how you can spawn the special ones.
Mob Bosses
When it comes to early progression in Sailor Piece, for the first 5k levels you will work through the Mob bosses. These don't drop any special Items which you need for Ascension or Specific quests, but they are essential for a quick progression.
| Boss | Spawn Information | Drops & Rewards |
|---|---|---|
| Thief Boss Mob Boss Level 25+ | Spawn Location: Starter Island | Money EXP Gems |
| Monkey Boss Mob Boss Level 500+ | Spawn Location: Jungle Island | Money EXP Gems |
| Desert Boss Mob Boss Level 1000+ | Spawn Location: Desert Island | Money EXP Gems |
| Winter Warden Mob Boss Level 2000+ | Spawn Location: Snow Island | Money EXP Gems |
| Panda Sorcerer Mob Boss Level 5000+ | Spawn Location: Shibuya Station | Money EXP Gems |

World Bosses (Timed Respawn)
World Bosses in Sailor Piece are the bosses which automatically spawn in again on a timer after you've killed them. You don't have to use any special items to summon them, just wait. You will be farming these early mid-game to get better weapons and boost your stats. However, keep in mind that the Sea 2 world bosses of Sailor Piece are for endgame content since they are incredibly OP.
Pro Tip: If you are farming for Sailor Piece Ascension levels or one of the mid tier Weapons, then we suggest teleporting around each of these Islands until they are all on a timer, then Server hopping. Solo Hunter is the most difficult at the start since Jinwoo is on a long timer, even without the additional wait for the Alucard Boss rotation. The Sea 2 bosses should be your go-to farming points when you reach late to endgame.

Summonable Bosses
There are two types of Summonable Bosses in Sailor Piece - those on Boss Island which usually require a Boss Key, and those which need special items to be summoned (like Strongest Sorcerer for example). Boss Keys drop from NPCs and Bosses, while you might have to complete certain quests for Special Summon Items. Keep reading to find out exactly how you can spawn each Boss.
Important Info: All of the information in the table below is for Bosses which you spawn on Easy Mode (with the exception of Bosses which only have one level to begin with). Their HP, Power and Drop Chances all scale up on each level.
