Sung Jinwoo Questline Requirements
Unlocking Sung Jinwoo involves several dungeon challenges:
- Clear the Red Commander Dungeon 15 times
- Defeat Sung Jinwoo 5 times using dual daggers
- Defeat Igris 10 times using dual daggers
These quests require repeated dungeon runs, so expect some grinding. Running with a strong team can speed this up.
How to Unlock Sung Jinwoo and Igris
Both characters are tied to the Red Commander Dungeon located in Rogue Town. This dungeon has 10 waves and two boss fights that drop the required materials.
- Location: Rogue Town
- Structure: 10 waves total
- Wave 5 boss: Igris
- Wave 10 boss: Sung Jinwoo
Each boss drops unique items needed for their respective unlocks.
Igris Drops
The Igris boss can drop:
- Igris weapon
- Skill books
- Title
- Accessory
To fully unlock Igris, you only need the weapon drop first. After that, you must use three books to open all of his skills. This makes Igris the simpler character to build compared to Sung Jinwoo.
Sung Jinwoo Drops
Sung Jinwoo can drop:
- Dual daggers
- Souls
- Title
- Accessory
To obtain Sung Jinwoo, you must visit the seller NPC on Starter Island. The unlock requirements are:
- 2 daggers
- 15 souls
- Diamond rank or higher
After meeting these conditions, you can start his questline.
Accessory Buff Comparison
Both characters come with powerful accessories that boost weapon damage:
- Igris accessory: 3.5× sword damage buff
- Sung Jinwoo accessory: 4× weapon damage buff
Sung Jinwoo’s accessory is currently one of the strongest general weapon buffs available, making it highly valuable even outside his main build.
Moveset and Combat Performance
Both Sung Jinwoo and Igris feature two main skills and cinematic cutscene attacks. Their abilities deal heavy burst damage and look impressive during fights. In terms of raw damage, Igris appears to hit harder in direct comparisons. Sung Jinwoo still performs very well and benefits from strong scaling and flexibility.
The cutscenes add style but can slightly slow down fast-paced farming runs. Because balance changes happen often, their exact ranking may shift over time. For now, both are strong picks and worth unlocking if you want top-tier dungeon performance.
Is It Worth Farming Both Characters?
Yes. Even if you prefer one playstyle, both characters offer valuable rewards. Igris provides high raw damage and a strong sword buff, while Sung Jinwoo offers one of the best universal weapon accessories in the game.
Farming the Red Commander Dungeon also helps you gather extra materials and experience, so the grind supports overall progression. Adding both Sung Jinwoo and Igris to your collection gives you more flexibility when building teams and experimenting with damage setups. Unlocking them takes time, but the payoff is a pair of powerful characters that stay relevant through much of the current meta in Rogue Piece.
