The Solo Leveling update in Reign Piece introduced one of the most hyped characters players have been waiting for: Crimson Commander Igris. And honestly, the hype makes sense. The developers didn’t just add another unit — they added a full progression path, a new dungeon, and several quality-of-life improvements that make the entire grind smoother.
If you’re planning to unlock Igris or just want to understand how the update works, this guide breaks down everything step-by-step — from the new features to the fastest way to farm materials and complete the questline.
All New Quality-of-Life Changes in the Update
Before jumping straight into Igris, the update actually added several small but important improvements to the game. These changes don’t look huge at first, but once you start playing, they make the experience noticeably better.
One of the biggest additions is the Title Vanity System. You can now equip titles purely for appearance without affecting your actual title progression. To use it, head to the reworked Starter Island and interact with the Title NPC. This allows you to show off your favorite title visually while still progressing toward another one.
Alongside this, the game now shows a Title Progression Bar, which tells you exactly what requirements you’re missing to unlock a specific title. Instead of guessing what you need to do next, the game now clearly shows your progress.
Another useful improvement is that accessory stats can now be viewed without equipping them. Previously, you had to equip every item just to see its stats. Now you can simply hover over accessories in your inventory and instantly check their attributes.
The update also added a VFX toggle for other players. If you’ve ever fought bosses in crowded servers, you already know how chaotic the screen can get with dozens of abilities going off. Turning off other players’ visual effects helps reduce lag and makes combat much easier to see.
Finally, the trading level requirement has been set to level 1500, and players can now equip heirlooms directly from the inventory, which saves a lot of time during gear management.
These changes may seem small individually, but together they make grinding and farming much smoother.
Where to Start the Igris Unlock Process
To begin unlocking Igris, you first need to travel to the reworked West Mountain Island.
Once you arrive there, look for the seller NPC, which is responsible for crafting the Crimson Commander Igris transformation. However, you won’t be able to craft it immediately. You’ll need to collect several rare materials first.
The required materials include:
- 25 Crimson Plates
- 20 Crimson Knight Shards
- 15 Crimson Scarlet Runes
- 7 King’s Oaths
- 1 Crimson Core
- Crimson Knight Trait
Most of these materials come from the new dungeon, which means you’ll be spending a lot of time farming it.
How to Access the New Dungeon
Before entering the dungeon, you need to complete a small preparation step.
First, find the Chahan NPC on West Mountain Island. She is responsible for opening the dungeon entrance, but she requires a Blood Key.
To obtain the Blood Key, you must defeat the Kyo Boss located on the same island. This boss has a chance to drop the key when defeated.
Once you get the Blood Key, return to the Chahan NPC and give it to her. This will unlock the dungeon entrance.
Dungeon Structure and Difficulty
The dungeon itself has three difficulty levels, and each difficulty has different drop chances for the materials needed to craft Igris.
One helpful feature added in this update is that the game now shows exact drop chances for each wave on every difficulty, so you know exactly what you’re farming.
The dungeon contains five waves in total.
The structure looks like this:
- Waves 1–4: Enemy waves that drop crafting materials
- Wave 5: The final boss encounter
The boss fight happens in a large arena room, and visually it’s one of the coolest dungeon designs the game has added so far.
For players trying to farm materials quickly, many people prefer running the easy difficulty repeatedly, since it can be cleared extremely fast once your character is strong enough.
In fact, experienced players can clear a run in around one minute, which makes it the fastest way to collect materials consistently.
Getting the Crimson Knight Trait
Even after collecting all dungeon materials, you still need one final requirement: the Crimson Knight Trait.
To obtain it, you must spin for the Swordsman Trait first.
Once you have the Swordsman Trait, you can begin the Igris Questline by interacting with the NPC tied to the transformation.
This questline contains several tasks that must be completed before your trait evolves.
Completing the Igris Questline
One of the key missions in the questline is completing a High Ranking Quest.
The fastest way to complete this objective is by defeating Hashira enemies, since they count toward the required progress and can be farmed quickly.
After finishing that step, you will need to complete the dungeon 25 times.
Many players choose to run the dungeon on easy mode for this stage because it’s much faster to clear repeatedly.
Yes, it sounds like a grind — but with quick clears, it doesn’t actually take that long.
Once all the quest steps are completed, you must travel to Shibuya and interact with the crafting NPC there.
This final interaction will evolve your trait from Swordsman into Crimson Knight, completing the Igris unlock process.
Igris Abilities and Moveset
After unlocking Crimson Commander Igris, you gain access to a brand-new moveset inspired by the character from Solo Leveling.
The abilities come with flashy animations and smooth combat effects that are noticeably improved compared to earlier skills in the game.
The update clearly shows the developers improving their animation quality, and the combat abilities feel powerful and satisfying to use.
During damage testing, Igris demonstrates extremely high damage output, making it one of the strongest additions to the game right now.
Players who enjoy aggressive combat builds will especially appreciate the abilities because they combine strong visuals with high burst damage.
Why Igris Is Considered So Strong
There are a few reasons why players are calling Igris “broken.”
First, the damage scaling is extremely high compared to many existing abilities in the game. Second, the skill animations allow for smooth combat flow without long delays.
And finally, because the update also improves accessory management and dungeon farming, it’s easier than ever to build powerful setups around characters like Igris.
If you’re aiming to stay competitive in Reign Piece, unlocking Igris as early as possible is definitely worth it.
This Solo Leveling update did more than just add a character.
It introduced a full progression system involving dungeon farming, trait evolution, crafting materials, and questline objectives. The new dungeon design looks great, the quality-of-life features improve the overall gameplay, and Igris itself feels like a genuinely powerful reward for players who complete the grind.
And if the developers stick to their schedule, this update is only the beginning.
The next major addition expected soon is Sung Jin-Woo, which means the Solo Leveling content in Reign Piece is likely going to expand even further.
So if you haven’t started farming yet, now is probably the best time to jump in.
