The Shadow Monarch sword is one of the strongest weapons you can obtain in Sailor Piece. Inspired by Sung Jin Woo from the Solo Leveling universe, this weapon delivers extremely fast attacks, powerful AoE abilities, and massive damage against bosses and mobs.
Because of its strength, getting this sword requires completing multiple quests, defeating bosses, and gathering rare materials.
If you are trying to unlock one of the best weapons in the game, here is the complete guide on how to get the Shadow Monarch sword in Sailor Piece.
Step 1: Get the Jinwoo Sword First
Before you can obtain the Shadow Monarch weapon, you must first unlock the Jinwoo Sword.
To do this, travel to Sailor Island and locate the Jinwoo Trainer NPC. This NPC is found in the right corner of the island.
The trainer will give you several quests that must be completed before you can purchase the Jinwoo Sword.
Jinwoo Quest Requirements
You must complete the following tasks:
• Take 15 million damage
• Kill 750 NPCs
• Deal 75 million damage
• Kill 35 players
• Defeat the Jinwoo boss 15 times
Once these challenges are completed, return to the NPC and buy the Jinwoo Sword.
Jinwoo Sword Cost
| Requirement | Amount |
|---|---|
| Money | 2,500,000 |
| Gems | 7,500 |
| Abyss Edge | 6 |
| Dark Ring | 3 |
| Shadow Heart | 1 |
These materials are dropped by the Jinwoo boss, which spawns on Sailor Island inside the large building.
Step 2: Find the Shadow Monarch NPC
After obtaining the Jinwoo Sword, the next step is to locate the Shadow Monarch NPC.
This NPC can be found on Dungeon Island, specifically on top of the large building roof.
Interact with the NPC to start the requirements for unlocking the Shadow Monarch sword.
Step 3: Defeat the Shadow Monarch Boss
To obtain the sword, you must farm materials dropped by the Shadow Monarch boss in the Dungeon.
The boss appears during Dungeon runs, and higher difficulty levels increase the drop chances of required materials.
Shadow Monarch Sword Requirements
| Item | Requirement |
|---|---|
| Monarch Core | 10 |
| Monarch Essence | 5 |
| Kamish Dagger | 2 |
| Shadow Crystal | 1 |
| King of Shadows Title | Required |
All of these items are dropped by the Shadow Monarch boss, but the drop rates are relatively low.
Step 4: Purchase the Shadow Monarch Sword
Once you collect all the materials, return to the Shadow Monarch Trainer NPC on Dungeon Island.
If you meet all requirements and have the Jinwoo Sword in your inventory, you can purchase the Shadow Monarch Sword.
The Jinwoo Sword will remain in your inventory even after unlocking the Shadow Monarch weapon.
