Map pieces are essential items in Sailor Piece that let you progress from Sea 1 to Sea 2. If you have been stuck wondering how to get map pieces in Sailor Piece, this guide covers everything you need to know about finding all seven pieces through boss farming.
Our team spent time reviewing player experiences from the Sailor Piece community to bring you accurate boss locations and drop mechanics. The process involves defeating specific bosses that drop these pieces randomly, but there are some important details that can save you hours of frustration.
You will learn exactly which bosses drop each map piece, why some pieces feel impossible to get, and strategies to improve your chances. Check out our Sailor Piece beginner guide if you need background on the game first.
Prerequisites for Farming Map Pieces
Before you can start farming map pieces, you need two Ancient Fragments and must have begun the Sea 2 quest. Players report that the Sea 2 map pieces quest is “horribly HARD” according to community discussions, so being prepared matters.
You also need Boss Keys to summon certain bosses. Check our guide on how to get Boss Keys if you are running low on this essential item for boss summoning.
Once you have the prerequisites, head to the appropriate island and defeat the assigned boss. Map pieces drop randomly with less than a 5% chance per kill, so patience is required. Some players have reported needing over 100 attempts before seeing their first drop, which is completely normal for this content.
Map Piece to Boss Location Guide (June 2026)
Each of the seven map pieces drops from a specific boss. Players in the community have mapped out which boss corresponds to each piece through extensive testing. Here is the complete breakdown of all seven map pieces and where to find them.
Map Piece 1 drops from Knight on Sailor Island. Knight is one of the earlier bosses you will encounter and makes for a good starting point in your farming journey.
Map Piece 2 drops from Limitless Sorcerer, also known as Sukuna, at Shibuya Station. This boss is part of the JJK update content and requires careful positioning to defeat.
Map Piece 3 drops from Qin Shi on Hollow Island. This boss has multiple phases and requires good dodging skills to defeat efficiently.
Map Piece 4 drops from Vampire King on Slime Island. Players consistently note this as the most challenging piece to obtain due to Vampire King’s complex attack patterns and relatively lower spawn rate.
Map Piece 5 drops from Aizen on Academy Island. Aizen is known for his illusion-based attacks that can confuse players during the fight.
Map Piece 6 drops from Ichigo, who appears on his designated boss island. Ichigo has a varied moveset that changes between phases.
Map Piece 7 drops from Gilgamesh. This final piece often takes the longest according to player reports, with many needing over 100 attempts before seeing this piece drop.
Additional bosses that drop map pieces include Excalibur, Soul Reaper, and Gojo Boss. For detailed information on unlocking Gojo V2 and Sukuna V2, see our Gojo V2 and Sukuna V2 unlock guide. These powerful bosses are part of Shinjuku Island content and drop highly sought-after items.
How the Drop System Works?
Random Drop Mechanics
Map pieces drop randomly when you defeat their assigned boss. The drop rate is less than 5% per kill, which means you could need dozens or even hundreds of attempts before a piece drops. There is no pity timer or protection mechanic in place.
One crucial detail that trips up many players: each player has five assigned bosses that can drop map pieces. This means not every boss on your server will yield a piece for you. Players have reported spending over 100 slime keys on a single boss with no map piece drop, only to discover they needed to kill a different boss instead.
The drop is entirely random. There is no guaranteed method or sequence that triggers the drop. Your assigned bosses are determined when you reach the Sea 2 quest requirement and cannot be changed.
Exclusions: Where Map Pieces Do NOT Drop
You cannot get map pieces from Boss Rush, Infinite Tower, or Dungeon bosses. Only the specific bosses listed above drop map pieces in the regular game world. This exclusion frustrates many players who try to farm efficiently through alternative content.
Boss Rush and Infinite Tower offer other rewards but do not contribute to your map piece collection. Stick to the main bosses for map piece drops to avoid wasting time on content that will never yield results.
Tips for Better Drop Rates (2026)
Luck Optimization
While you cannot guarantee a drop, you can improve your chances through luck optimization. Having more luck increases your chance of rare drops in many games, and Sailor Piece appears to follow a similar system. Prioritize luck-boosting gear and accessories when preparing for boss farming sessions.
Consider using latest Sailor Piece codes before boss fights, as some codes provide temporary stat boosts that might improve your drop chances. Codes are updated regularly, so check back frequently for new ones.
Choosing the right race also matters for boss fights. Our best races for boss fights guide can help you pick a race optimized for damage output and survival, which keeps you farming longer without needing to reset.
Efficient Farming Order
Many experienced players recommend starting with the bosses closest to your spawn point to save travel time. Track which bosses you have killed hundreds of times without a drop, as those might not be your assigned bosses.
If a specific boss is giving you trouble, look for alternative bosses that drop the same map piece. ProGameGuides notes that alternate boss options exist if you are struggling with the primary location, so you have options if one boss proves too difficult.
Our best farming methods guide covers general efficiency tips that apply to map piece grinding, including optimal boss routes and time-saving strategies.

Why are my map pieces not dropping?

Use active codes that provide stat boosts, select a race with luck bonuses, and equip any luck-enhancing items you have acquired. Unfortunately there is no guaranteed way to increase map piece drop rates.

The Babylon key is used to summon certain bosses in the game. It is required for boss fights that drop rare items including some map pieces.
