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.Table of ContentsAll Sailor Piece Boss Locations & DropsOpen World BossesSpawnable BossesDungeon BossesUnavailable BossesHow to Spawn Bosses in Sailor PieceHow to Get Boss Spawn ItemsHow to Farm Boss Keys in Sailor PieceHow to Spend Boss TicketsSailor Piece Bosses FAQsAll Sailor Piece Boss Locations & Drops Bosses in Sailor Piece either spawn on their own or you summon them by interacting with specific NPCs. 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.

Dungeon Bosses

Dungeon NPC on Dungeon Island allows you to enter Dungeons and fight bosses such as Shadow and Shadow Monarch. 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.

How to Spawn Bosses in Sailor Piece

You can summon bosses on the Boss Island by interacting with the Boss Summoner NPC.
Summoning bosses on the Boss Island costs Boss Tickets, Cash, and Gems.
Some bosses have to be spawned on islands other than the Boss Island.

[/url] [/url] [/url] 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

You can craft Divine Grails on the Boss Island using Broken Swords.
You can craft Slime Keys on the Slime Island using Slime Shards.
