The Copy skill, added with the Yuta update, is arguably the most flexible ability in Jujutsu Zero. Rooted in Rika's powers from the Jujutsu Kaisen series, it lets you permanently absorb and reuse moves from any boss or NPC you kill while in Rika Manifestation state. You can hold up to four copied skills at once, swapping them out whenever you want a different set of stolen abilities. Getting there takes some grind, but the payoff, using moves like Dismantle from Sukuna or Maximum Meteor from Jogo against other bosses, makes it worth the effort.
What do you need to unlock Copy (Rika)?
Before you can even think about the unlock, you need two things sorted. First, obtain the Rika Cursed Technique from the gacha banner. Second, grind quests until you hit 100 Mastery with that technique. Neither of those steps is skippable.
Rika skill tree in Mastery menu
Once you hit 100 Mastery, you need four specific materials to activate Copy from the Rika skill tree in the Mastery menu. Here is exactly what the game requires:
The Domain Fragment and Heavenly Fragment share the same crate pool, so farming crates kills two birds with one stone. Focus on higher-grade crates first since they tend to have better odds.
How to get Memory Shards
Memory Shards come from the Past Rika NPC, located in the top-left corner of the map. She offers three one-time quests: Memories I, Memories II, and Memories III. Each quest sends you to find specific memories scattered around the map, and each one rewards a single Memory Shard on completion.
These quests are not repeatable, which actually works in your favor here. You need exactly three shards, and there are exactly three quests that give one each. Complete all three and you are done with this material permanently.
Since the Memory quests are non-repeatable, do not skip them early in your playthrough. Complete them as soon as the Past Rika NPC makes them available so the shards are ready when you hit 100 Mastery.
How to get the Binding Jewel
This is the grind-heavy part. The Binding Jewel drops from the Yuta mini-boss at a 2% rate, which means you should expect to farm him multiple times before it drops.
Here is how to reach him:
- Talk to the Rika NPC to trigger the Yuta mini-boss spawn.
- Head to the top-left corner of the map, between the Awakened Lightning God and the St. Patrick's Event Shop.
- Defeat him. The fastest method, according to the source, is summoning Rika and spamming M1 attacks.
- If no Binding Jewel drops, the quest is repeatable, so you can keep going back.
At a 2% drop rate, getting the Binding Jewel can take many attempts. Do not burn out farming other materials while waiting. Knock out the Memories quests and crate farming in parallel to make better use of your time.

How does the Copy skill actually work?
Once Copy is unlocked, the mechanic is straightforward but powerful. While in Rika Manifestation, defeat any boss on the map. After the kill, that boss gets highlighted. Press T to absorb their move. That ability is now yours to use for as long as Rika is active, or until you copy something else into that slot.
You have four copy slots total. Each slot holds one skill from a different boss. Replace any slot by copying a new skill into it. Some of the strongest options confirmed in the source material include:
- Dismantle from Sukuna
- Maximum Meteor from Jogo
- Gravel Jump from Judgeman
The ability to stack four boss moves simultaneously is what makes Copy one of the strongest techniques for boss fights. You are essentially turning your enemies' own abilities against them.
Is Copy worth the grind?
Yes, particularly for players who spend a lot of time in boss content. The combination of four simultaneous stolen abilities, including top-tier moves like Maximum Meteor, makes Copy one of the most flexible and high-damage options in the game. The Memory Shard quests are easy. The crate farming for Domain and Heavenly Fragments is passive. The Binding Jewel is the only real bottleneck, and even that clears up once you settle into a farming rhythm.
