Map Pieces are essential collectibles in Sailor Piece that you need to unlock Sea 2. There are 7 Map Pieces total, and each one drops from specific bosses when you defeat them. The catch? Each player only has five assigned bosses that can drop map pieces, and the drops are completely random. Expect to grind the same bosses multiple times before you collect all seven pieces.
Before you start hunting for Map Pieces, you need to meet two requirements. First, collect 2 Ancient Fragments from your adventures in Sea 1. These fragments serve as your entry ticket to the farming content. Second, you must begin the Sea 2 quest to activate the drop system. Without starting this quest, bosses will not drop Map Pieces regardless of how many times you defeat them.
Once you have the Ancient Fragments and the quest is active, you can start farming any of the bosses associated with Map Pieces. Remember that Boss Rush, Infinite Tower, and Dungeon bosses do NOT drop pieces. Only open-world bosses on specific islands count.
Each Map Piece corresponds to a specific boss or set of bosses. Here is the complete mapping of which bosses drop which pieces.
The first Map Piece drops from bosses found on Boss Island. Multiple bosses patrol this island, so explore thoroughly to find one that spawns consistently.
This piece drops from the bosses that guard Shibuya Station. Clear the area systematically to find your assigned boss.
Sailor Island hosts the bosses responsible for dropping the third Map Piece. Check both the main platform and surrounding areas.
The Academy Island bosses drop Map Piece 4. These are typically mid-tier challenges, but still require attention.
Hollow Island bosses drop the fifth Map Piece. This area can be tricky to navigate, so use your map markers.
Despite the name, Slime Island has challenging bosses that drop Map Piece 6. Do not underestimate the enemies here.
The final Map Piece drops from Shinjuku Island bosses. This is often reported as the hardest piece to obtain, so budget extra time for this grind.
The drop rate for Map Pieces is less than 5%, making each drop feel like a small victory. Each player receives five assigned bosses that can drop pieces. If you are not getting drops, it could mean your assigned boss is not currently spawning, or you simply have not hit the RNG yet.
Forum players report spending 100 or more attempts on a single piece. Some users got lucky and received pieces on their first try, while others reported dozens of failed attempts. The randomness affects everyone equally, so stay patient.
Some players report that Map Pieces stop spawning unexpectedly. If this happens, try relogging or server-hopping to reset your boss spawns.
While you cannot control the drop rate, you can maximize your chances through sheer volume. Spend more time in areas with faster boss respawns. Some bosses respawn within seconds of being defeated, allowing for rapid kill-and-check cycles.
Start with bosses closest to your spawn point for efficiency. Work outward to the more distant islands only after securing nearby pieces. Save Shinjuku Island for last since it tends to be the most time-consuming.
Based on player reports, expect to spend several hours to a full day of farming to collect all 7 pieces. Casual players might spread this across multiple sessions. Dedicated grinders can push through in one extended session if RNG cooperates.
Map pieces have a drop rate under 5% and each player only has five assigned bosses that can drop them. Keep grinding your assigned bosses consistently. If pieces stop spawning entirely, try relogging or server-hopping to reset the spawn system.
You need 2 Ancient Fragments collected and must start the Sea 2 quest. Without the quest active, bosses will not drop map pieces regardless of how many you defeat.
There are 7 Map Pieces total in Sailor Piece. All 7 are required to unlock Sea 2 and continue your adventure.
The drop rate is less than 5%, making map pieces quite rare. This is why most players need to defeat bosses dozens or even 100+ times to collect all pieces.
Map Piece 7 from Shinjuku Island is generally considered the hardest to obtain. Players consistently report needing the most attempts for this final piece.
Getting Map Pieces in Sailor Piece requires patience and persistence. Collect your 2 Ancient Fragments, start the Sea 2 quest, then systematically farm bosses across the islands.
Each of the 7 Map Pieces drops from specific bosses with a sub-5% drop rate. Accept that some pieces will take dozens of attempts. Focus on efficient farming routes and stay consistent.
Once you collect all 7 pieces, Sea 2 opens up and your next adventure begins.
