Farming bosses for powerful Swords, Melee (Combat) Specs, Accessories, and other items is the go-to of every Sailor Piece player in the late game. However, bosses are important to grind in all stages of progression, and finding the right ones to fight early on can be challenging. With that in mind, we prepared the following all Sailor Piece boss locations and drops guide to help you out.

All Sailor Piece Boss Locations & Drops
Some bosses in Sailor Piece spawn naturally in several locations; others can be spawned by interacting with specific NPCs around the map. Specific bosses only spawn in Dungeons, such as Shadow and Shadow Monarch, for example. To get drops from a boss, you need to damage it for at least 10% of its HP. The pity system guarantees you get a rare drop from every 25th boss you defeat. So, a good strategy for farming rare boss items is to defeat 24 easy bosses, and then do one boss you need items from to trigger the pity drop.
Below is a list of all bosses in Sailor Piece, along with their locations and drops:
Open World Bosses
Open world bosses respawn at set intervals since they have been defeated. Since most open-world bosses respawn every 5 minutes, you can easily farm all of them on a private server and farm regular mobs while waiting for them to respawn again.

Spawnable Bosses
Spawnable bosses need to be spawned by you or other players at certain NPCs using specific items. If you are missing the items needed to spawn a specific boss, you can find other players farming the same boss on the Sailor Piece Discord server and join them for the grind.

Dungeon Bosses
Dungeon bosses only appear at specific waves of certain Dungeons. Grinding these bosses requires you to stay in the same dungeon, which means that you won’t be able to efficiently grind world bosses at the same time. Dungeon bosses count towards the boss pity drop counter, which is handy if you want to stack it up before going back to regular boss farming.
| Boss | Drops | Spawn Location |
|---|---|---|
| • Umbral Capsule (12.5%) • Void Seed (4.5%) • Shadow Essence (2%) • Atomic Core (0.75%) • Shadow Cloak [Accessory] (0.85%) • Eminence in Shadow [Title] (1%) | Cid Dungeon (Waves 5/10/15) Cost: 1x Dungeon Ticket | |

Unavailable Bosses
Some bosses appear only during seasonal and other events. Once the event is over, bosses are removed from the game, and they might be available again in the future. The only way to get items that drop from them in the meantime is by trading with other players.
| Boss | Drops | Spawn Location |
|---|---|---|
| • Haki Color Reroll (75%) • Race Reroll (45%) • Trait Reroll (35%) • Boss Ticket (30%) • Dungeon Key (25%) • Wyrm Band (25%) • Black Frost (9%) • Silver Requiem (3.5%) • Ragna Sigil [Accessory] (2%) • Dragon Slayer [Title] (1.5%) | Christmas Island (5m cooldown) [Unavailable] |
How to Spawn Bosses in Sailor Piece
You can spawn bosses at specific NPCs on several islands in Sailor Piece using specific items related to them. Most early game bosses can be spawned at the Boss Island using Boss Keys, Cash, and Gems. Other bosses, such as Anos and Rimuru, can be summoned on their own islands using items that drop from enemies on them.
How to Get Boss Spawn Items
Most items needed to spawn bosses in Sailor Piece drop from specific enemies, so it isn’t possible to farm all of them at the same time. Here is a list of all boss spawn items, with information on how to obtain each one:
| Boss Spawn Item | Obtainable From | Used To Spawn |
|---|---|---|
 Boss Key | All types of Chests All non-boss enemies Regular island Quests Merchant Dungeon Shop Event Shop NPCs Trade | Saber Qin Shi Ichigo |
 Limitless Key | Gojo Boss (Shibuya Station) Strong Sorcerer (Shinjuku Island) Trade | Strongest of Today |
 Malevolent Key | Sukuna Boss (Shibuya Station) Curse (Shinjuku Island) Trade | Strongest in History |
 Divine Grail |  Crafted using 3 Broken Swords Broken Swords drop from all enemies when using Swords Trade | Gilgamesh |
 Slime Key |  Crafted using 2 Slime Shards Slime Shards drop from Slime Warriors (Slime Island) Trade | Rimuru |
 Calamity Seal | Academy Teacher (Academy Island) All enemies (Rare) Trade | Anos |
 Dungeon Key | All types of Chests All Bosses Merchant Trade | Shadow Shadow Monarch |
How to Farm Boss Keys in Sailor Piece
The best way to get Boss Keys in Sailor Piece is to farm regular enemies on the most difficult island, where you can consistently one-shot them. An alternative, but reliable, method is farming Strong Sorcerers and Curse enemies on Shinjuku Island by using the Quake Fruit’s C skill at a specific position near the spawn. Simply position yourself as described in the image above and use the C move off-cooldown to instantly defeat both packs of enemies at the same time.
Besides defeating enemies, you can obtain Boss Keys from all types of Chests as well, and purchase them directly from the Merchant, Dungeon, and some other event NPCs.
How to Spend Boss Tickets
As you defeat bosses, you will keep gaining more and more Boss Tickets, which you can spend at the Boss Exchange on the Boss Island to purchase certain Swords and Melee (Combat) Specs. For now, Boss Tickets only serve as a soft-pity system in cases where you don’t manage to obtain all of the items needed to get Swords or Melee Specs, such as Qin Shi and Ichigo.

Sailor Piece Bosses FAQs
To be eligible to receive drops from a boss, you need to deal damage equal to at least 10% of its HP. Otherwise, you won’t receive drops from it.
The best method for farming Boss Keys in Sailor Piece is to repeatedly defeat both packs of mobs on Shinjuku Island at the same time using the Quake Fruit’s C skill.
Before you can spawn the Anos boss in Sailor Piece, you need to complete a quest that requires you to find and interact with two Demonite Fragments on the Academy Island. One of the fragments is on a branch right next to the island spawn, while the other is on the tower section of the Academy building, close to the Anos Trainer NPC. After you complete the quest, you can spawn the Anos boss using Calamity Seals.
