Domain Fragment is the key item that turns a strong build in Jujutsu Zero into a late-game monster. Without it, the fourth mastery slot on compatible cursed techniques stays locked, and your Domain Expansion never shows up in combat, no matter how high your level is.
Check that your cursed technique can use Domain Expansion
Before worrying about Domain Fragment drops, make sure you are on a cursed technique that actually has a Domain Expansion.
Step 1: Open the in-game menu and go to the Overview tab, then open Mastery.
Step 2: Look at your skill slots. Most standard cursed techniques show three skills. If you see a fourth slot with a locked skill (for example, Unlimited Void on Limitless), that slot is the Domain Expansion you can eventually unlock.
Step 3: If there is no fourth slot, that cursed technique does not have a Domain Expansion. You will need to reroll or swap to a technique that shows a fourth mastery skill if you want to use a Domain.
On compatible techniques, hovering or selecting the locked fourth skill shows that it unlocks a Domain Expansion and lists its requirements. That is where Domain Fragment comes in.
Requirements to unlock Domain Expansion
Unlocking the Domain Expansion from that fourth mastery slot always follows the same formula:
- 100 Mastery on the cursed technique (e.g., Limitless at 100 mastery).
- 100,000 Yen (sometimes shown as 100k Yen).
- Exactly one Domain Fragment or Domain shard item, depending on the terminology used in your menu.
Once all three conditions are met, the lock on the fourth skill can be removed, and the Domain Expansion becomes a normal ability on your bar, with its own cooldown (around 60 seconds in the case of Unlimited Void).
How to get Domain Fragment from Jogo Raids (fastest method)
The most efficient way to farm Domain Fragment in Jujutsu Zero is by looping Jogo raids. These runs are short, repeatable, and reward chests that can contain the fragment.
Step 1: From the main city, reset or return to the spawn point.
Step 2: At spawn, look for the Raids NPC standing very close to where you appear. Interact and confirm to enter the Raids Lobby.
Step 3: In the lobby, choose Create, then set up a Jogo Raid.
Step 4: Select the difficulty. For pure Domain Fragment farming, pick Easy. These runs take roughly 30 seconds with a decent build and are very forgiving for new players.
Step 5: Start the raid, defeat Jogo, and finish the run. Each clear awards you a volcanic chest (the exact chest name can vary slightly with updates).
Step 6: Stack up a reasonable number of chests, then start opening them in bulk. Purple or higher-grade chests have noticeably better odds of dropping a Domain Fragment, but even lower grades can hit it.
Players regularly see Domain Fragment appear quite early when opening purple volcanic chests from Easy Jogo raids, which is why this loop is widely treated as the fastest and safest route. Higher difficulties like Hard or Nightmare add pressure without improving fragment drops enough to matter for most players focused on unlocks rather than loot min-maxing.
How to get Domain Fragment from raids generally
Jogo is the preferred target, but Domain Fragment is part of the wider raid reward pool. Any time you complete a raid and receive end-of-raid chests, there is a chance the fragment appears when you open them.
Step 1: Queue into any available raid from the Raids Lobby.
Step 2: Clear the raid completely to earn the chest rewards.
Step 3: Open your chests from the inventory. Each chest has a non-zero chance to contain a Domain Fragment.
This method is ideal if you are already grinding raids for special-grade items or other loot and want to passively pick up Domain Fragments along the way, rather than running only Jogo on Easy.
How to get Domain Fragment from world chests
Domain Fragment (sometimes labeled as Domain shard in inventory text) can also drop from high-grade chests scattered across the map. This is slower than focused Jogo farming, but useful when you are exploring anyway.
There are two chest types worth targeting:
- Grade One chests that spawn randomly in the open world.
- Special Grade chests you get as rare loot, often from raid rewards such as volcanic chests.
Step 1: While exploring, keep an eye out for standalone chests in the environment. Grade One chests have the right tier to contain a Domain shard.
Step 2: Search mountain tops and elevated terrain. Grade One chests frequently appear on high ground rather than at street level.
Step 3: Open every Grade One or Special Grade chest you find. Both can drop Domain shard, though the odds are low on any single chest.
Alternative: High-difficulty Jo Raid for Special Grade chests
For players comfortable with harder content, Jo raid on higher difficulties can indirectly boost Domain Fragment acquisition through better chest quality.
Step 1: Enter the Raids Lobby and start a Jo Raid on Hard or Nightmare difficulty, assuming your build can handle it.
Step 2: Farm Jo repeatedly until you have a large stack of volcanic chests (for example, around 50).
Step 3: Open the volcanic chests. These frequently upgrade into Special Grade chests, which have strong odds of giving Special Grade items, including Domain shard.
This path has a steeper difficulty curve than Easy Jogo looping, but rewards better gear alongside your Domain item. It makes sense once you have a Domain on one character and want to gear up and unlock another at the same time.
Using Domain Fragment to unlock Domain Expansion
Once a Domain Fragment or Domain shard is sitting in your inventory, you are one menu away from actually gaining the Domain Expansion.
Step 1: Confirm that your cursed technique mastery is at 100 and that you have at least 100,000 Yen. If masteries lag behind, continue fighting or running raids until the bar is capped.
Step 2: Open Overview > Mastery again and select the locked fourth skill on your compatible technique (for example, Unlimited Void on Limitless).
Step 3: Press the unlock button. The game will consume 1 Domain Fragment (or Domain shard), 100,000 Yen, and apply the 100 mastery requirement.
Step 4: After unlocking, bind the Domain Expansion to a key or slot as you would any active skill and take it into combat.
Once active, Domain Expansion radically shifts your damage and crowd control. Unlimited Void, for instance, creates a huge arena that locks enemies in with you, extends combos, and keeps them stunned long enough to delete bosses such as Jogo much more safely. Cooldown sits at around a minute, which is short enough to use every fight when you are farming.
Quick FAQ on Domain Fragment and Domain Expansion
Do all cursed techniques have Domain Expansion?
No. Only techniques that show a fourth mastery skill slot can unlock a Domain. If your technique only ever shows three skills in the Mastery screen, it does not support Domain Expansion.
What is the fastest way to get Domain Fragment?
Running Easy Jogo Raids on repeat and opening the volcanic chests you earn is the fastest and safest way for most players. The runs are short, low risk, and the purple chests you get from them can drop Domain Fragment quickly.
Can you unlock Domain Expansion without doing raids?
Yes. Domain shard can drop from Grade One and Special Grade chests in the open world, but the drop rates and spawn randomness make this slower than targeted raid farming.
Does Domain Expansion have a cooldown?
Yes. Domain abilities have a cooldown of about 60 seconds after use. That window is short enough that you can reliably use your Domain every fight while farming or doing raids, instead of treating it as a once-per-boss panic button.
If you want the smoothest path, max the mastery on a Domain-compatible cursed technique first, grind Easy Jogo Raids until a Domain Fragment drops, then unlock the fourth mastery skill as soon as you hit 100,000 Yen. From that point on, the Domain itself speeds up every other grind you take on in Jujutsu Zero.
