Slime Pieces are special collectibles hidden throughout the game world. When you gather all seven pieces and combine them with Slime Shards, you can craft a Slime Key at the Slime Key Crafter NPC. This key allows you to spawn the Rimuru boss on Slime Island, one of the major boss encounters in the game.

How to Start the Slime Collection Quest

You cannot find Slime Pieces until you officially start the Slime Collection quest. Many players skip this step and wonder why pieces are not appearing on the islands. Here is exactly what you need to do first.

Step 1: Travel to Slime Island

Open your map and locate Slime Island. Use the portal system to teleport there. Slime Island serves as the central hub for this entire quest chain, so you will be returning here multiple times.

Step 2: Find the Slime Key Crafter NPC

Once you arrive on Slime Island, look for the Slime Key Crafter NPC. This character stands in a visible area near the center of the island. The NPC handles both starting the quest and crafting your Slime Key once you have collected all the pieces.

Step 3: Talk to the NPC and Accept the Quest

Interact with the Slime Key Crafter and select the option to start the Slime Collection quest. The NPC will explain that you need to find seven Slime Pieces hidden across different islands. After accepting, you will see a confirmation that the quest has begun.

One common question players ask is whether quest progress saves. The answer is yes. Your progress saves automatically when you exit the game, so you can collect pieces over multiple sessions without losing your work.

How to Find All Slime Pieces in Sailor Piece

Now that the quest is active, you can start collecting the seven Slime Pieces. Each piece is located on a different island, and we recommend collecting them in the order below for maximum efficiency. The route starts from easier islands and progresses to more challenging locations.

Slime Piece #1: Desert Island (Dragon Fossil)

Head to Desert Island through the portal system. Once you arrive, look for the massive Dragon Fossil skeleton. The Slime Piece is hidden between the bones of this fossil structure. Walk around the fossil and check the gaps between the ribcage bones. This is one of the easier pieces to find since the fossil is a prominent landmark. The piece blends into the sandy environment, so look carefully for a glowing or slightly different colored object tucked between the bones.

Slime Piece #2: Snow Island (Igloo Area)

Use the portal to travel to Snow Island. Navigate toward the igloo structure. The Slime Piece is located near or just behind the igloo. Because of the white snow environment, the piece can be tricky to spot against the white background. Circle around the igloo completely and check the surrounding snow mounds. Some players report the piece being slightly buried in snow, so look for any unusual textures or glints in the snow near the igloo.

Slime Piece #3: Starter Island (Building Rooftop)

Teleport to Starter Island using the portal. This piece requires some climbing and jumping skills. Look for a building with an accessible rooftop. The Slime Piece is positioned on top of this building. You will need to use your dash and jump abilities to reach the roof. Start by climbing any nearby structures and then jump across to the target building. This location rates as medium difficulty because of the platforming required.

Slime Piece #4: Jungle Island (Large Tree)

Travel to Jungle Island via the portal. Search for the large, prominent tree in the area. The Slime Piece is hidden around the base or in the roots of this tree. The jungle environment is dense, but the large tree stands out as a landmark. Check around the trunk and between the exposed roots. This piece is relatively easy to find once you locate the correct tree.

Slime Piece #5: Shibuya Station (Building Structure)

Portal to Shibuya Station island. This urban-style area has multiple buildings and structures. The Slime Piece is located on or near one of the main building structures. Look for a building with distinctive architecture and check the exterior walls, rooftops, and alcoves. You may need to do some climbing to reach the piece. The urban environment makes navigation more complex, earning this location a medium difficulty rating.

Slime Piece #6: Hueco Mundo (Domed Building)

Travel to Hueco Mundo through the portal system. Look for the domed building structure. The Slime Piece is positioned near this distinctive architecture. The area has a unique visual style that differs from other islands. Search around the perimeter of the domed building and check any nearby structures. Some players report needing to climb partially up the dome to reach the piece.

Slime Piece #7: Shinjuku Island (Watchtower)

Your final piece is on Shinjuku Island. Use the portal to get there. Locate the watchtower structure on the island. The Slime Piece is at or near the watchtower. This may require climbing to reach higher sections of the tower. The watchtower is a tall, thin structure that serves as a clear landmark. Once you collect this seventh piece, you will receive a confirmation message that your Slime Collection quest is complete.

How to Craft the Slime Key

After collecting all seven Slime Pieces, return to Slime Island and speak with the Slime Key Crafter NPC. However, you also need Slime Shards to craft the key. Here is how to get them.

Getting Slime Shards

Slime Shards drop from Slime Warrior enemies on Slime Island. These enemies are Level 8000, making them challenging for lower-level players. The drop rate for Slime Shards is not 100 percent, so you will need to defeat multiple Slime Warriors to gather enough shards.

The fastest way to farm Slime Shards is to continuously defeat Slime Warriors on Slime Island. Some players also report that the Rimuru boss drops Slime Shards, though Slime Warriors remain the most consistent source. Bring healing items and prepare for extended farming sessions.

Crafting Your Key

Once you have collected enough Slime Shards along with your seven Slime Pieces, return to the Slime Key Crafter NPC. Interact with the NPC and select the crafting option. The NPC will combine your materials into a Slime Key.

When the crafting completes, you will see a message that says “Slime Quest completed! Craft is now unlocked.” This confirms you have successfully finished the entire quest chain.

What the Slime Key Does

The Slime Key has one primary purpose: spawning the Rimuru boss on Slime Island. Rimuru is a major boss fight in Sailor Piece that drops valuable rewards. To spawn this boss, use your Slime Key at the designated spawn location on Slime Island.

The Rimuru boss fight requires preparation. Make sure your character is strong enough to handle a Level 8000+ boss encounter. Bring healing items, upgrade your equipment, and consider teaming up with other players for the fight.

Tips and Common Mistakes to Avoid

After helping many players complete this quest, here are the most common mistakes and how to avoid them.

Start the Quest First

The number one mistake players make is traveling to islands before talking to the Slime Key Crafter NPC. Without the quest active, Slime Pieces will not spawn. Always visit Slime Island first.

Use Visual Landmarks

Each piece is hidden near a specific landmark. Focus on finding the landmark first, then search the immediate area. The dragon fossil, igloo, large tree, domed building, and watchtower are all distinctive landmarks that stand out from their surroundings.

Check Multiple Angles

Pieces blend into their environments. A piece near the igloo may be nearly invisible against white snow. Circle landmarks completely and look from different angles to spot the piece.

Come Prepared for Platforming

Some pieces require jumping and climbing. Make sure you understand your movement abilities. The Starter Island piece specifically requires reaching a rooftop, so practice your jumps.

Optimal Collection Route

For efficiency, we recommend this order: Desert Island, Snow Island, Starter Island, Jungle Island, Shibuya Station, Hueco Mundo, and finally Shinjuku Island. This route minimizes backtracking and starts with easier locations.

Troubleshooting Missing Pieces

If a piece is not appearing at a location, first confirm you started the quest. Then double-check you are at the correct island and landmark. If problems persist, try rejoining the game or checking our Sailor Piece Trello and Wiki resources for the latest game updates.

Next Steps After Completing the Quest

Once you have your Slime Key and have defeated the Rimuru boss, you may want to continue progressing your character. Check out our skill trees and runes guide to unlock powerful abilities and further strengthen your character.
