How to Get Domain Fragment in Jujutsu Zero

In Jujutsu Zero, unlocking your Domain Expansion is one of the biggest power upgrades in the game. But to do that, you need a rare item called the Domain Fragment (sometimes shown as Domain Shard).

Without this item, your build will never reach its true late-game strength. Even if your level is high, your Domain Expansion will stay locked.

This guide explains what Domain Fragment is, how to get it fast, and how to use it to unlock Domain Expansion, all in simple and clear steps.

What Is Domain Fragment in Jujutsu Zero?

Domain Fragment is a special key item used to unlock the fourth mastery skill of certain cursed techniques. This fourth skill is always the Domain Expansion.

If you do not have a Domain Fragment:

• Your fourth mastery slot stays locked

• Your Domain Expansion never appears in combat

• Your build remains incomplete

This item is required no matter how strong or high-level your character is.

Check If Your Cursed Technique Can Use Domain Expansion

Before farming for Domain Fragment, make sure your cursed technique actually supports Domain Expansion.

Step 1: Open the Mastery Menu

• Open the in-game menu

• Go to the Overview tab

• Select Mastery

Step 2: Look at Your Skill Slots

• Most techniques show three skills

• If you see a fourth locked skill, that is the Domain Expansion

Example:

• Limitless → Fourth skill is Unlimited Void

Step 3: No Fourth Slot? No Domain

• If your technique only shows three skills

• That technique cannot unlock a Domain

• You must reroll or switch techniques

Hovering over the locked fourth skill will show:

• Domain Expansion name

• Required items (including Domain Fragment)

Requirements to Unlock Domain Expansion

Every Domain Expansion follows the same unlock rules:

You need:

• 100 Mastery on that cursed technique

• 100,000 Yen (100k Yen)

• 1 Domain Fragment (or Domain Shard)

Once all requirements are met:

• The fourth mastery skill unlocks

• Domain Expansion becomes a normal usable ability

• Cooldown is around 60 seconds

Fastest Way to Get Domain Fragment: Easy Jogo Raids

The best and fastest method to get Domain Fragment is farming Easy Jogo Raids.

These raids are:

• Very short (around 30 seconds)

• Low risk

• Repeatable

• Great for new and mid-game players

Step-by-Step Jogo Raid Farming

Step 1: Return to spawn or reset to main city

Step 2: Find the Raids NPC near spawn and interact with it

Step 3: Enter the Raids Lobby and select Create Raid

Step 4: Choose Jogo Raid

Step 5: Select Easy difficulty

Step 6: Start the raid and defeat Jogo

Step 7: Finish the run and collect the volcanic chest

Open your chests after stacking several runs.
Purple volcanic chests have very good chances to drop Domain Fragment, even on Easy mode.

Higher difficulties are not needed if your goal is just the Domain Fragment.

Getting Domain Fragment From Other Raids

Domain Fragment is part of the general raid reward pool.

That means:

• Any raid can drop it

• It comes from end-of-raid chests

Steps:

1. Join any raid from the Raids Lobby

2. Clear the raid fully

3. Open the reward chests in your inventory

This method is useful if you are already farming raids for other items and want to get Domain Fragment naturally.

---

Getting Domain Fragment From World Chests

You can also find Domain Fragment in the open world, but this method is slower.

Chest Types That Can Drop It:

• Grade One chests

• Special Grade chests

How to Farm World Chests:

1. Explore the map while grinding or traveling

2. Look for standalone chests in the environment

3. Search mountain tops and high areas, where Grade One chests spawn more often

4. Open every Grade One or Special Grade chest you find

Drop rates are low, but this method works well in early progression.

---

Alternative Method: High-Difficulty Jo Raids

If you are strong enough, Hard or Nightmare Jo Raids can help indirectly.

Steps:

1. Start Jo Raid on Hard or Nightmare difficulty

2. Farm many runs to collect volcanic chests

3. Open chests and upgrade them into Special Grade chests

Special Grade chests have higher chances to drop Domain Fragment.

This method is best for experienced players who want:

• Better gear

• Domain Fragment at the same time
