Sung Jinwoo Guide Reign Piece – How to Get the Shadow Monarch Character

Reign Piece recently expanded its Solo Leveling themed content with another major update. This time, the spotlight is on Sung Jinwoo, one of the strongest characters inspired by the famous Shadow Monarch from the Solo Leveling series. With powerful skills, a damage buff mode, and strong combat abilities, Sung Jinwoo quickly became one of the most talked-about additions in the game.

Players who want to unlock this character will need to farm several materials from the new raid content introduced in the update. While the process requires some grinding, the reward is a powerful ability set that performs well in dungeons and combat. This guide explains where to find the NPC, the required materials, and how the new dungeon system works in Reign Piece.

Where to Get Sung Jinwoo in Reign Piece

To unlock Sung Jinwoo, you need to visit the Sung Jinwoo Seller NPC located on West Mountain Island.

Before you can purchase the character, you must collect several special materials. These items mainly drop from the Double Dungeon Raid, which is part of the new Solo Leveling update.

Required Materials

Here are the materials needed to obtain Sung Jinwoo:

• 10 Mana Crystals
• 7 Assassin Essence
• 5 System Interface
• 1 Night Killer
• 1 Venom Fang
• Fame requirement
• In-game currency

Most of these materials come from the new dungeon system, so players will need to repeatedly clear raids to gather everything.

How to Unlock the Double Dungeon Raid

The materials required for Sung Jinwoo are mainly obtained from the Double Dungeon. However, players must unlock this raid first. Follow these steps to access it:

Step 1 – Get the Blood Key

First, defeat the Kyito Boss to obtain the Blood Key. This key is used to access Igris’ dungeon.

Step 2 – Clear Igris Dungeon

Use the Blood Key to enter Igris Dungeon. After clearing the dungeon successfully, you will receive the Double Dungeon Key.

Step 3 – Enter the Double Dungeon

With the key obtained, you can now enter the Double Dungeon Raid, where most of Sung Jinwoo’s materials drop.

Double Dungeon Overview

The Double Dungeon is a wave-based raid with multiple stages.

Key details about the dungeon:

• Contains 10 waves of enemies
• Includes different difficulty levels
• Higher difficulty increases drop chances

Difficulty Rewards

Each difficulty offers different rewards:

Normal Difficulty

• Auras
• Cosmetic outfits
• Basic drops

Hard Difficulty

• Heirlooms
• Better drop chances
• Higher rarity materials

Players who want to farm Sung Jinwoo materials faster should run the dungeon on Hard difficulty, as the drop rates are noticeably better.

Sung Jinwoo Moveset Overview

Sung Jinwoo has a strong combat kit with several skills that can be used together smoothly. One of the most useful aspects of his moveset is that multiple skills can be chained together without interrupting attacks. This allows players to deal consistent damage while still using abilities. Important features of the moveset include:

• Large AoE attack skills
• Smooth skill chaining
• Strong damage output
• Mode transformation ability

These abilities make Sung Jinwoo very effective in both dungeon farming and boss fights.

G Move – Damage Mode Buff

One of Sung Jinwoo’s key abilities is the G Move, which activates a special mode that boosts damage.

When this mode is active:

• Attack power increases
• Skills deal higher damage
• Combat becomes much more aggressive

Using this mode before entering a wave or boss fight can significantly increase your overall damage output.

The Solo Leveling expansion in Reign Piece continues to grow with the addition of Sung Jinwoo. Unlocking him requires completing the Double Dungeon system and collecting several rare materials, but the effort is worth it for players who want a powerful combat character.

With strong AoE attacks, a damage boosting mode, and smooth skill combos, Sung Jinwoo stands out as one of the strongest additions in the current update. If you are farming the new raid content, working toward unlocking this Shadow Monarch character is definitely a goal worth pursuing.
