How to Get the Binding Jewel in Jujutsu Zero (Rika Copy Skill)

What the Binding Jewel Is

The Binding Jewel is the rarest component in the Rika manifestation chain — the item standing between you and the Copy skill, which lets you steal, store and deploy abilities taken from the game’s toughest bosses.

Where It Drops

The jewel is tied to the Yuta mini-boss added in the Yuta update. It is a low-rate drop, so plan for repeat kills rather than a single lucky run:

  • Learn the boss’s punish windows before speed-farming — deaths cost more time than careful clears.
  • Bring your highest-damage clan/technique pairing (see the Clan Tier List) to shorten each cycle.
  • Drop luck is unaffected by difficulty modifiers players have tested so far; consistency of clears is what matters.

After You Get It

The jewel feeds into the Rika questline — see our Rika Quest walkthrough for the full chain that ends in unlocking Copy. Once Copy is live, boss abilities like Maximum-Meteor-class moves become part of your own kit.

Farming Checklist

  1. Redeem all active codes — the Lumens fund your rolls while you farm.
  2. Clear the Yuta mini-boss on repeat until the jewel drops.
  3. Complete the Rika quest steps to convert the jewel into the Copy unlock.
