How to Get Obtain Jinwoo Monarch

All requirements for Jinwoo Monarch are found inside the Double Dungeon, located on Dungeon Island. This dungeon is structured with 15 waves of enemies, and the final boss you’ll face is Sun Jinwoo — the key to unlocking Monarch items.

Before you enter, make sure your build is ready, because the waves get progressively harder and the boss fight demands good gear and skill. To evolve Jinwoo into his Monarch form, you must collect several specific items. Here’s what you need:

• King of Shadows Title
• Jinwoo (base form)
• 10 Monarch Cores
• 5 Monarch Essences
• 2 Kamish Daggers
• 1 Shadow Crystal

All of these materials are obtained from the Double Dungeon, so focus your runs here until every item is complete.

How to Get Each Material

1. Monarch Cores & Monarch Essences

These are the core evolution materials you need most of. They drop from various waves and bosses inside the Double Dungeon. Because drop rates can be random, expect to run the dungeon multiple times to fill your inventory.

2. Kamish Daggers & Shadow Crystal

These rare items drop from later waves and the final boss — especially Sun Jinwoo himself. Prioritize farming the higher waves if possible to improve your chances.

Tips for Beating the Double Dungeon

The Double Dungeon is tougher than the standard version, so here are some tips to help:

• Level Up Before Entering: Having stronger stats will help you clear waves faster and survive longer against bosses.
• Upgrade Accessories: Better gear increases DPS and survivability, which is important for late waves.
• Use AOE Skills: Since there are many waves, strong AOE damage helps clear mobs faster and save time.
• Know the Boss Patterns: Sun Jinwoo’s attacks are powerful but predictable once you’ve fought him a few times.

Is Jinwoo Monarch Worth Getting?

Yes — once you unlock Monarch form, Jinwoo becomes significantly stronger. His skills hit harder, clear waves faster, and his overall presence in PvE content improves. If you enjoy dungeon farming and want a high-impact character for mid to late game, progressing toward Monarch is a solid goal.

Getting Jinwoo Monarch requires dedication, farming, and repeated dungeon runs, but the payoff is strong. Focus your efforts on the Double Dungeon, gather all required materials, and push your build toward higher DPS and survivability. Once Monarch is unlocked, Jinwoo becomes one of the more formidable units you can use in Sailor Piece — a reward that’s worth the grind.
