How to Get the Shadow Monarch Sword in Sailor Piece (2026)

Learning how to get the Shadow Monarch Sword in Sailor Piece is one of the most common goals for serious players in this Roblox anime-inspired game. This mythical-tier weapon sits at the top of the meta, offering devastating shadow-based attacks that dominate both PvP arenas and PvE boss encounters.

I spent about 35 hours grinding through the entire quest chain to obtain this sword, and I will walk you through exactly what to expect. The process involves completing the Jinwoo sword prerequisites first, then farming specific items from the Shadow Monarch boss on Dungeon Island. Expect the full journey to take between 20 to 40 hours depending on your efficiency and dungeon difficulty settings.

This guide breaks down every step with time estimates, drop rate optimization strategies, and tips I wish I knew before starting. Whether you are a PvP-focused player chasing the meta or a completionist hunting every mythical weapon, this walkthrough covers everything you need.

What You Need Before Starting

The Shadow Monarch sword is not something you can grab immediately. The game gates this weapon behind a substantial prerequisite chain that tests your patience and grinding capability.

Here is what you need before you can even think about obtaining the Shadow Monarch:

• Jinwoo Sword: You must first obtain the Jinwoo sword by completing its entire quest chain and purchasing it from the Jinwoo Trainer
• Level Recommendation: While there is no hard level lock, I recommend being at least level 5000+ before attempting the Shadow Monarch boss farms
• Currency Reserve: You will need 2.5 million money and 7500 gems for the Jinwoo sword purchase alone
• Time Investment: Block out 20 to 40 hours of gameplay depending on your farming efficiency

The entire process splits into two major phases. Phase one covers obtaining the Jinwoo sword through its five-quest chain. Phase two involves farming the Shadow Monarch boss for specific drops and purchasing the final sword. Most players underestimate the time needed for phase one, especially the quest requiring 35 player kills.

Step 1: Speak to the Jinwoo NPC on Sailor Island

Your journey begins on Sailor Island, the main starting area where you will find the Jinwoo NPC. This character stands near the central plaza area, typically surrounded by other players also working through their progression.

Look for an NPC named Jinwoo near the training grounds. He offers the Jinwoo sword quest chain that serves as your gateway to eventually obtaining the Shadow Monarch. Speaking to him initiates the five-quest sequence you must complete.

Before starting the quests, check your inventory space and currency. You will need significant storage for the items you will collect, and the final purchase requires 2.5 million money plus 7500 gems. I recommend having at least 3 million money saved up to cover any incidental costs during the quest chain.

Step 2: Complete the Jinwoo Quest Chain

This is where most players spend the majority of their time. The Jinwoo quest chain consists of five specific challenges that test different aspects of your gameplay. Here is the complete breakdown with tips for each:

Quest 1: Take 15 Million Damage

This quest sounds intimidating but is actually one of the easier ones. You need to absorb 15 million points of damage from any source. The fastest way involves letting low-level enemies hit you repeatedly or standing in environmental damage zones.

I completed this in about 45 minutes by finding a cluster of weak enemies and letting them attack while I watched videos on another screen. Do not waste healing items here. Just let the damage accumulate naturally.

Quest 2: Kill 750 NPCs

This quest requires defeating 750 non-player characters. Any NPC counts toward this total, so focus on areas with dense enemy spawns. The starting beach areas or low-level dungeons work perfectly.

Expect this to take 2 to 3 hours of dedicated grinding. Use area-of-effect attacks if your build supports them. Grouping enemies together and using multi-target skills speeds this up significantly.

Quest 3: Deal 75 Million Damage

Here you must inflict 75 million damage points to enemies. This sounds like a lot, but boss fights accelerate this progress dramatically. Focus on high-health bosses rather than weak grunts.

The Shadow Monarch boss himself counts toward this total, so you can progress this quest while farming for your eventual sword purchase. I recommend tackling this alongside other activities rather than grinding it exclusively.

Quest 4: Kill 35 Players

This is where many players get stuck. You need 35 PvP kills to progress. If you are not comfortable with PvP, this becomes the biggest bottleneck in the entire quest chain.

My strategy involved joining PvP-focused servers during peak hours when more casual players were online. Focus on players who appear to be farming or distracted. Do not engage obvious PvP veterans unless you are confident in your build.

Alternatively, coordinate with friends who need the same quest. Trading kills back and forth works if you can find trustworthy partners. This quest alone took me about 6 hours of intermittent PvP attempts.

Quest 5: Kill the Jinwoo Boss 15 Times

The final quest requires defeating the Jinwoo boss 15 times. This boss spawns at specific intervals, so you will need to learn his spawn timing or camp his location.

The Jinwoo boss appears in a designated arena area. Check server announcements or ask other players about recent spawns. Each kill requires a legitimate fight, so bring your best gear and consumables.

Expect 15 kills to take 3 to 5 hours depending on spawn rates and competition from other players. Higher traffic servers mean more competition for boss tags.

Purchasing the Jinwoo Sword

After completing all five quests, return to the Jinwoo NPC on Sailor Island. He will now offer the Jinwoo sword for purchase at 2.5 million money and 7500 gems.

Buy the sword and equip it. You now have the prerequisite item needed to begin the Shadow Monarch acquisition process. The Jinwoo sword itself is a decent weapon, though most players immediately start working toward its upgrade.

Step 3: Speak to the Shadow Monarch NPC on Dungeon Island

With your Jinwoo sword in hand, travel to Dungeon Island. This location houses the Shadow Monarch NPC who sells the sword you actually want. Finding him requires some navigation.

Land on Dungeon Island and head toward the main dungeon chamber structure. Enter the building and locate the staircase or climbing path to the roof. The Shadow Monarch NPC stands on the roof of the dungeon chamber, specifically in the left corner when facing the structure.

If you are having trouble finding the roof access, look for grapple points, ladders, or jumping puzzles that lead upward. Some servers have player traffic that can guide you. Follow other high-level players heading to the roof.

Speak to the Shadow Monarch NPC to see his shop inventory. He offers the Shadow Monarch sword, but you cannot purchase it yet. First, you need to farm specific items from the Shadow Monarch boss that spawns elsewhere on the island.

Step 4: Purchase the Shadow Monarch Sword

The Shadow Monarch NPC sells the sword for a combination of currency and rare drops. Here is the complete purchase requirement:

• 10 Monarch Cores – Dropped by Shadow Monarch boss (rarest item)
• 5 Monarch Essences – Dropped by Shadow Monarch boss
• 2 Kamish Daggers – Dropped by Shadow Monarch boss
• 1 Shadow Crystal – Dropped by Shadow Monarch boss
• King of Shadows Title – Obtained through boss defeat milestone
• Currency: Additional money and gems required

The King of Shadows title unlocks automatically after defeating the Shadow Monarch boss multiple times. Most players earn this naturally while farming for the other items.

Farming these items represents the second major time sink in this process. The drop rates vary significantly based on dungeon difficulty, which I will explain in the optimization section below.

Complete Shadow Monarch Requirements

Here is the full requirements breakdown organized for easy reference:

Jinwoo Sword Prerequisites

Quest	Requirement	Est. Time
Quest 1	Take 15 million damage	30-60 min
Quest 2	Kill 750 NPCs	2-3 hours
Quest 3	Deal 75 million damage	2-4 hours
Quest 4	Kill 35 players (PvP)	4-8 hours
Quest 5	Kill Jinwoo boss 15 times	3-5 hours
Purchase	2.5M money + 7500 gems	Varies

Shadow Monarch Sword Requirements

Item	Quantity	Drop Rate (Easy)	Drop Rate (Hard)
Monarch Core	10	6.75%	12%
Monarch Essence	5	15%	25%
Kamish Dagger	2	10%	18%
Shadow Crystal	1	8%	15%
King of Shadows	Title	Auto at 10 kills	Auto at 10 kills

The drop rates shown above represent community-tested averages. Individual results will vary due to RNG. Running higher dungeon difficulty significantly improves your farming efficiency.

How Long Does It Take to Get Shadow Monarch?

This is the question every player asks, and most guides avoid answering directly. Here is my honest time breakdown based on personal experience and community feedback:

Phase 1: Jinwoo Sword (12-20 hours)

The Jinwoo quest chain takes most players between 12 and 20 hours of active gameplay. The PvP quest creates the biggest variance. Players comfortable with PvP might finish in 12 hours, while those struggling with player combat could spend 20+ hours.

Currency farming adds additional time if you do not already have the 2.5 million money and 7500 gems saved. Earning this from scratch typically requires 3 to 5 hours of dedicated money-making activities.

Phase 2: Shadow Monarch Farming (8-20 hours)

Farming the Shadow Monarch boss for all required items takes 8 to 20 hours depending on your luck and difficulty setting. Running on Easy difficulty with bad RNG can push this toward 25 hours. Running on Hard difficulty with decent luck can reduce this to 6 to 8 hours.

The Monarch Cores create the biggest bottleneck. Needing 10 of these at a 6.75% drop rate means statistically requiring 148 boss kills on Easy difficulty. At Hard difficulty with 12% drop rate, you need approximately 84 kills.

Total Time Investment

Realistic total: 20-40 hours

Efficient players running Hard difficulty with good RNG and PvP skills can finish in 20 hours. Average players taking their time on Easy difficulty might spend 40+ hours. Most players land somewhere in the middle around 30 hours.

This assumes dedicated grinding sessions. Spreading the grind across multiple days with breaks actually improves efficiency since you avoid burnout and maintain focus during boss fights.

Farming Optimization: Get Your Items Faster

After grinding through this process myself, I discovered several strategies that significantly speed up farming. These optimization tips address the biggest content gap in competitor guides.

Dungeon Difficulty Scaling

The single biggest factor affecting your farm speed is dungeon difficulty. Here is how difficulty impacts drop rates:

• Easy: Base drop rates (6.75% for Monarch Core)
• Medium: 1.3x drop rate multiplier
• Hard: 1.8x drop rate multiplier
• Nightmare: 2.5x drop rate multiplier (requires high level/gear)

Running Hard difficulty effectively doubles your Monarch Core drop rate compared to Easy. This cuts your required boss kills nearly in half. However, Hard difficulty requires significantly stronger gear and player skill.

I recommend attempting Hard difficulty only if you can clear the boss in under 3 minutes without using consumables. If fights take longer or require healing items, stick to Medium until your gear improves.

Boss Spawn Timing

The Shadow Monarch boss spawns on a timer, typically every 15 to 20 minutes depending on server settings. Learning this timing prevents wasted waiting.

Join populated servers for faster boss spawns. More players triggering spawn conditions means more frequent opportunities. However, popular servers also mean more competition for the kill.

Consider farming during off-peak hours when fewer players compete for boss tags. Early morning or late night sessions often yield more kills per hour despite slightly slower spawn rates.

Efficient Farming Routes

Optimize your farming loop by preparing everything in advance:

1. Stock up on healing items and buff consumables before starting
2. Set your spawn point near the boss location
3. Join a party with other farmers for faster clears
4. Use your best damage build, even if it is not your preferred playstyle
5. Keep track of spawn timers using a stopwatch or phone app

Party farming works exceptionally well if you find a group all working toward Shadow Monarch. Coordinate kills so everyone gets credit, and share information about spawn timers.

Currency Farming Tips

If you need to earn the 2.5 million money and 7500 gems from scratch, focus on these efficient methods:

• Dungeon clears: Complete full dungeon runs for money rewards
• Daily quests: Prioritize money and gem rewards
• Boss sales: Sell unwanted boss drops to other players
• Trading: Flip items on the marketplace if you understand the economy

Dungeon runs on higher difficulties provide the most consistent money per hour. A dedicated money-farming session of 2 to 3 hours should cover most of your currency needs.

Shadow Monarch Sword Skills and Abilities

Understanding what you are working toward helps maintain motivation during the long grind. The Shadow Monarch sword offers one of the most powerful movesets in Sailor Piece.

Basic Attacks

The sword features fast, shadow-infused slashes that deal dark attribute damage. Basic attacks chain together smoothly with excellent mobility between strikes. The attack speed feels noticeably faster than heavy weapons like Ragna.

Special Abilities

Shadow Dash: A quick teleportation move that repositions you while leaving a shadow clone that distracts enemies. Excellent for both offensive repositioning and defensive escapes.

Monarch’s Wrath: Unleashes a wide-area shadow explosion dealing massive damage to all enemies in range. This ability has a moderate cooldown but hits hard enough to clear groups of NPCs instantly.

Sovereign Strike: A charged heavy attack that deals increased damage based on how long you hold the charge. Fully charged, this ability rivals ultimate attacks from other weapon classes.

Army of Shadows: Summons shadow soldiers that fight alongside you temporarily. These minions draw aggro and deal additional damage, making this ability valuable for both PvE and PvP.

PvP Effectiveness

In player versus player combat, Shadow Monarch ranks among the top-tier weapons. The combination of mobility from Shadow Dash and burst damage from Monarch’s Wrath creates a deadly kit. Experienced PvP players value the unpredictable movement patterns this sword enables.

The Army of Shadows ability particularly shines in PvP, as the summoned minions can interrupt enemy combos and create openings for your attacks. Many high-level PvP players consider Shadow Monarch essential for competitive play.

PvE Effectiveness

For player versus environment content, Shadow Monarch performs excellently against bosses and groups alike. The area-of-effect damage from Monarch’s Wrath clears dungeon trash efficiently, while the single-target burst handles boss health pools.

Some players prefer Rimuru for pure PvE story content due to different ability scaling, but Shadow Monarch remains competitive in all PvE scenarios. The versatility of having both strong AoE and single-target damage makes this sword valuable for any content type.

Shadow Monarch vs Other Mythical Swords

Before committing 20 to 40 hours to this grind, consider how Shadow Monarch compares to alternatives. Here is how it stacks against other top-tier mythical swords:

Shadow Monarch vs Rimuru

Rimuru offers slightly better PvE clear speed due to slime-based area damage that scales with enemy density. However, Shadow Monarch outperforms Rimuru in PvP situations where burst damage and mobility matter more than sustained AoE.

The Rimuru sword typically requires less time investment to obtain, making it attractive for casual players. If you primarily play PvE and want a strong sword without the massive grind, Rimuru serves as an excellent alternative.

Shadow Monarch vs Ragna

Ragna focuses on heavy, slow attacks with massive single-hit damage. Shadow Monarch trades some of that raw power for significantly better attack speed and mobility. In extended fights, Shadow Monarch’s faster attacks often result in higher total damage output.

Ragna suits players who prefer deliberate, powerful strikes. Shadow Monarch fits players who want fast-paced combat with repositioning options. Both are viable for endgame content.

Shadow Monarch vs Shadow Sword

The base Shadow sword shares thematic elements but pales in comparison to its Monarch upgrade. Shadow sword works as a budget option for players building toward Monarch, but the difference in power is substantial. Consider Shadow sword as a stepping stone rather than a final destination.

Which Should You Choose?

Choose Shadow Monarch if:

• You want the best PvP weapon in the current meta
• You value mobility and fast attacks
• You are willing to invest 20+ hours of grinding
• You want versatility across all content types

Consider alternatives if:

• You primarily play PvE and want faster clear speeds (Rimuru)
• You prefer heavy-hitting slow weapons (Ragna)
• You cannot commit to the long grind time
• You are still building up your character level and gear

Frequently Asked Questions

Is the Shadow Monarch Sword Worth It?

After spending 35 hours obtaining the Shadow Monarch sword and using it extensively in both PvP and PvE content, I can give you an honest assessment of whether how to get the Shadow Monarch Sword in Sailor Piece is a journey worth taking.

For competitive PvP players, this sword is absolutely worth the investment. The combination of mobility, burst damage, and shadow abilities creates a toolkit that dominates the current meta. I have won significantly more PvP encounters since equipping Shadow Monarch compared to my previous setup.

For PvE-focused players, the answer depends on your alternatives. If you already have Rimuru or another mythical sword, the upgrade to Shadow Monarch is nice but not essential. However, if you are using lower-tier weapons, the jump to Shadow Monarch transforms your dungeon-clearing experience.

The 20 to 40 hour time investment represents the biggest barrier. Spread across several weeks of casual play, the grind feels manageable. Attempted in marathon sessions, it becomes exhausting. I recommend pacing yourself and treating each quest as its own mini-goal rather than focusing on the distant finish line.

Ultimately, the Shadow Monarch sword delivers on its reputation as one of the best weapons in Sailor Piece. The journey to obtain it tests your dedication, but the reward justifies the effort for serious players. Good luck with your grind, and may your Monarch Core drops be plentiful.
