The latest Fusion Piece update has introduced one of the most exciting upgrades yet: Kamish Wrath Jinwoo, also known by many players as Jinwoo V2. Inspired by Sung Jinwoo’s powerful Kamish Daggers, this new form brings impressive visuals, a brand-new questline, and stronger abilities that make it a worthwhile goal for endgame players.
Alongside Kamish Wrath Jinwoo, the update also adds Modulo Yuji, another powerful character that you’ll want to unlock if you’re planning to experience everything this update has to offer.
This guide covers both unlock methods, all known requirements, and whether the grind is actually worth your time.
Fusion Piece Kamish Wrath Jinwoo Guide – How to Unlock, Quest
The update introduces two major additions:
- Modulo Yuji
- Kamish Wrath Jinwoo (Jinwoo V2)
Modulo Yuji was added with the previous content update, while Kamish Wrath Jinwoo is the main highlight of the newest release.
Both require farming materials and defeating bosses, although Kamish Wrath Jinwoo involves a longer questline.
How to Unlock Modulo Yuji
Before going after Kamish Wrath Jinwoo, you may also want to unlock Modulo Yuji.
The process is fairly straightforward once you know where everything comes from.
Step 1: Visit JJK City
Travel to the newly added JJK City Island.
Here you’ll find the NPC that begins the Modulo Yuji progression.
One of the required materials is the:
- Remainder’s Core
This item drops from enemies located throughout JJK City, so you’ll need to defeat plenty of mobs before moving on.
Step 2: Spawn the Modulo Yuji Boss
Once you’ve gathered the initial requirements, head over to Fusion Island.
Here you can summon the Modulo Yuji Boss.
Defeating this boss rewards most of the materials needed to complete the unlock process, so expect to farm it multiple times.
Step 3: Craft the Modulo Singularity
One important item cannot be obtained as a normal drop.
You’ll need to craft:
Modulo Singularity
To craft it:
- Visit Fusion Town
- Spend 25 Broken Equations
Broken Equations drop from the Modulo Yuji Boss, so keep farming until you’ve collected enough.
After crafting the Modulo Singularity and gathering the remaining materials, you’ll be able to unlock Modulo Yuji.
How to Unlock Kamish Wrath Jinwoo
Kamish Wrath Jinwoo is the biggest feature of this update.
Unlike Modulo Yuji, unlocking this form requires completing a dedicated questline alongside farming a brand-new dungeon.
Step 1: Find the Kamish Wrath NPC
The NPC that starts the Kamish Wrath questline is located on the Starter Island.
Speak with the NPC to view the required materials.
Almost everything needed comes from the newly added dungeon.
Step 2: Enter the New Dungeon
To begin farming materials, travel to:
Demon Slayer Island
Once there, enter the:
Red Commander Dungeon
This dungeon contains the materials required for Kamish Wrath Jinwoo.
However, before entering, you’ll need another important item.
Step 3: Get the Dungeon Entry Item
The required dungeon item isn’t found inside the dungeon itself.
Instead, it drops from the:
Jinwoo V1 Boss
This boss can be summoned in:
Fusion Town
Farm the Jinwoo V1 Boss until you receive the required dungeon item, then return to the Red Commander Dungeon and begin collecting materials.
Kamish Wrath Jinwoo Questline
After obtaining the necessary materials, you’ll receive three quests.
Quest 1
Defeat:
- 20 Sung Jinwoo Bosses
This is the longest part of the entire questline since it requires repeatedly farming the same boss.
Quest 2
Defeat:
- 3 Kamish Wrath Jinwoo Bosses
Compared to the first objective, this one is much shorter but still requires a capable character or party.
Quest 3
Use:
- Jeepo 199 times
This final objective is mostly about repetition.
Simply continue using the required ability until you’ve reached the total count.
Once all three quests are complete, you’ll officially unlock Kamish Wrath Jinwoo.
Kamish Wrath Jinwoo Showcase
One of the biggest highlights of the update is the presentation.
Kamish Wrath Jinwoo comes with:
- New visual effects
- Stylish skill animations
- A unique system UI pop-up
- An impressive Arise cutscene
The overall effects feel much more polished than many previous abilities, making the transformation satisfying to use during combat.
The animations alone make the unlock feel rewarding after finishing the grind.
Is Modulo Yuji Worth Unlocking?
Modulo Yuji is much easier to obtain compared to Kamish Wrath Jinwoo.
Most of the grind revolves around:
- Farming JJK City enemies
- Defeating the Modulo Yuji Boss
- Crafting the Modulo Singularity
If you’re already farming the new content, it’s definitely worth unlocking along the way.
Is Kamish Wrath Jinwoo Worth the Grind?
For most endgame players, the answer is yes.
Although you’ll spend some time farming bosses and repeating dungeon runs, the overall unlock path is clear and straightforward. The new abilities look fantastic, the visual effects are among the best currently available in Fusion Piece, and the overall presentation makes Kamish Wrath Jinwoo feel like a true upgrade over the original Jinwoo.
If you’re looking for your next long-term goal after finishing previous content, Kamish Wrath Jinwoo is easily one of the best additions in this update and well worth working toward.
