Jujutsu Zero Halloween Gear Guide: Spooky X, Y, Z and Mixed Set Test

How to get all six Halloween gear pieces

Spooky Yellow, Orange, Red, X, Y and Z all come from Hallow Crates. They are only obtainable during the 2026 Halloween Event, so collect the pieces you want while the event is available.

Spooky Raid rewards 15 Hallow Crates per clear. Hosting costs 150 Spooky Candy, and the boss has 30 trillion health. Bring a group to make the runs more manageable. If your group can clear it comfortably, you can collect gear crates alongside the other raid rewards.

You can also buy Hallow Crates from the Event Shop for 100 Spooky Candy each. This is an alternative when you have saved candy, but large batches can quickly use up your balance.

Hallow Crate gear drop rates

These are the listed chances for the six gear pieces in Hallow Crates. Z is the rarest, but the damage comparison below shows why rarity alone should not decide your entire setup.

• Spooky Yellow — 8.4%.
• Spooky Orange — 4.2%.
• Spooky Red — 1.7%.
• Spooky X — 0.8%.
• Spooky Y — 0.4%.
• Spooky Z — 0.3%.

Spooky Set bonuses: one, two and three pieces

Spooky gear also provides bonuses for filling multiple slots. You can mix X, Y and Z while keeping all three equipped pieces in the Spooky Set.

• 1 piece — +50% EXP.
• 2 pieces — +15% Hallo Scythe damage amplification.
• 3 pieces — +33% cooldown reduction.

Spooky Yellow: the starting option

All gear stats in this guide are shown at gear level 30, rank 3 and Ascension 5. These are upgraded item values, not fresh-crate stats. Player-level requirements are listed separately.

Spooky Yellow is Grade Two, requires player level 100 and has the highest listed gear drop chance at 8.4%. It is a starting option while you fill your gear slots and collect the other pieces.

• Main stats: 136.5 flat ATK and +293% critical damage.
• Additional bonuses: +50% Cursed Energy and +300% ATK.

Spooky Orange: higher attack and critical damage

Spooky Orange is Grade One, requires player level 100 and has a 4.2% drop chance. At the same upgrade stage, it increases the listed flat ATK, critical damage, percentage ATK and Cursed Energy bonuses compared with Yellow.

• Main stats: 195 flat ATK and +390% critical damage.
• Additional bonuses: +70% Cursed Energy and +400% ATK.

Spooky Red: Special Grade progression

Spooky Red is Special Grade, requires player level 100 and has a 1.7% drop chance. Its listed stats continue the increases from Yellow and Orange. Use the pieces that improve your current build while working toward X, Y and Z.

• Main stats: 292.5 flat ATK and +488% critical damage.
• Additional bonuses: +100% Cursed Energy and +500% ATK.

Spooky X: flat attack

Spooky X requires player level 200 and has a 0.8% drop chance. Flat ATK is a major part of its stat mix: the main stats include 390 flat ATK, and its additional bonuses add another 300. X is worth keeping even though it is more common than Y and Z.

• Main stats: 390 flat ATK and +390% ATK.
• Additional bonuses: +300 flat ATK and +500% critical damage.

Spooky Y: percentage attack

Spooky Y requires player level 300 and has a 0.4% drop chance. It emphasizes percentage ATK while still supplying flat ATK and critical damage, giving it a different stat mix from X.

• Main stats: +780% ATK and +390% critical damage.
• Additional bonuses: +500% ATK and +300 flat ATK.

Spooky Z: critical damage

Spooky Z requires player level 300 and has a 0.3% drop chance. Its main and additional bonuses both contribute critical damage, alongside flat and percentage ATK. It gave the strongest result among the three matching-piece setups in this test.

• Main stats: +780% critical damage and 292.5 flat ATK.
• Additional bonuses: +500% ATK and another +500% critical damage.

Damage test: three X vs three Y vs three Z vs mixed

Ashira tested four gear combinations using Idle Transfiguration's first skill. The matching setups were fairly close: three X pieces dealt about 1.482 billion, three Y dealt 1.509 billion, and three Z dealt 1.544 billion damage.

That puts three Y about 27 million ahead of three X, with three Z another 35 million above three Y. Moving from three X to three Z improved the result by approximately 4.2%.

One X, one Y and one Z reached 1.643 billion damage, the highest result of the four. It beat three Z by about 99 million damage, or 6.4%. Compared with three Y it was about 8.9% higher, and compared with three X it was about 10.9% higher.

• 3 × Spooky X — approximately 1.482B damage.
• 3 × Spooky Y — approximately 1.509B damage.
• 3 × Spooky Z — approximately 1.544B damage.
• 1 × X + 1 × Y + 1 × Z — approximately 1.643B damage.

What to keep and upgrade first

For this Idle Transfiguration setup, aim for one Spooky X, one Spooky Y and one Spooky Z before chasing three copies of Z. The mixed setup combines their different stat profiles, keeps all three slots within the Spooky Set and requires only one copy of the rarest piece.

You can use matching pieces while collecting the missing items. Three X pieces still reached about 1.482B in the test, so there is no need to wait for the full mixed setup before using Halloween gear. The same principle applies if you have several Y pieces or get a Z early.

Check auto-sell before opening a large batch of Hallow Crates. Turn Auto-Sell off for X, Y and Z so those pieces stay in your inventory. In the screenshot below, the green Auto-Sell buttons are enabled: switch them off for the pieces you want to keep. Upgrade the pieces you intend to use and compare them with your existing gear when trying a different weapon or technique.

Quick recommendation

Farm Hallow Crates, keep a copy of each X/Y/Z piece and work toward the mixed setup if you are following this Idle Transfiguration build. It won this comparison at approximately 1.643B damage, versus 1.544B with three Z pieces. Use the best pieces you already have while collecting the rest.
