Domain Expansion Requirements in Jujutsu Zero

Before anything else, you need to make sure your Cursed Technique supports Domain Expansion.

1. Open the Overview menu
2. Go to the Mastery tab
3. Look at your skill list

Normal techniques usually have three skills. If your technique shows a fourth locked skill, that skill is the Domain Expansion. For example, techniques like Unlimited Void clearly show that Domain Expansion can be unlocked. If your technique does not have a fourth skill slot, it means that technique cannot unlock a Domain Expansion.

What Is a Domain Fragment?

To unlock Domain Expansion, you must first obtain a Domain Fragment. This is a required item and cannot be skipped. The fastest and most reliable way to get a Domain Fragment is by farming raids and opening raid chests.

Fastest Way to Get a Domain Fragment

Step 1: Go to the Raid Lobby

• Reset your character
• Return to the spawn area
• Talk to the Raid NPC next to spawn
• Select Yes to teleport to the raid lobby

Step 2: Create a Raid

• Choose Create Raid
• Select a Raid
• Difficulty options: Easy, Normal, Hard, Nightmare

For speed and efficiency, Easy mode is the best choice, especially for beginners.

Why Easy Raids Are the Best

• Takes around 30 seconds per run
• Very easy to clear
• Gives one chest per completion
• Can be spammed repeatedly without risk

Harder modes are not required for Domain Fragment farming, so Easy mode is the fastest overall.

Opening Chests and Getting the Domain Fragment

After farming multiple raids:

1. Open your chests
2. Domain Fragments can drop from higher-rarity chests, including purple chests
3. Drops are RNG-based, but repeated Easy raids make this very fast

Once you obtain the Domain Fragment, check it in:

• Inventory → Supplies

Unlocking Domain Expansion

After getting the Domain Fragment, you still need:

• 100 Mastery
• 100,000 Yen

How to Unlock

1. Open Mastery
2. Select your locked Domain Expansion skill
3. Spend the Domain Fragment, mastery, and yen
4. Unlock the skill

Once unlocked, the Domain Expansion becomes usable in combat.

How Domain Expansion Works In-Game

• Massive area control
• Free and easy combos
• Extremely strong for farming raids and bosses
• Long active duration
• Around 60 seconds cooldown, which is very short for its power

After unlocking it, farming Jo raids and enemies becomes much easier and faster.

Best Tips to Unlock Domain Expansion Faster

• Spam Easy Raids Easy raids give the best time-to-reward ratio. Do not waste time on higher difficulties early.
• Save Yen Early Make sure you already have enough yen before the Domain Fragment drops so you can unlock instantly.
• Use Domain Expansion to Farm More Once unlocked, raids become even faster, helping you progress toward endgame much more smoothly.

Unlocking Domain Expansion in Jujutsu Zero is much faster than most players expect if you follow the right method. Make sure your technique supports it, farm Easy Jo raids for chests, get the Domain Fragment, and unlock it as soon as you hit the mastery and yen requirement. Once you have Domain Expansion, both farming and combat become significantly easier, giving you a huge advantage going forward.
