Reign Piece New Codes (JJK Update)

Players can redeem several new codes released with the update. Some of them require a certain level before they can be used.

Here are the currently available codes:

  • 1KINTERESTED
  • NOONEDOESITLIKEREIGNPIECEDOES
  • RYOMENSUKUNA – Requires Level 3000
  • HUGEUPDATEJJK – Requires Level 1000

Because the game now has code requirements, players must reach specific levels, ranks, or fame milestones before redeeming certain rewards.


New Level Cap and Stat Cap

This update increases the maximum progression limits in the game. New limits include:

  • Level Cap: 3250
  • Stat Cap: 6500

These increases allow players to continue strengthening their builds, especially when using the new specs added in the update.


New Specs Added in the Update

Three new specs inspired by Jujutsu Kaisen were added.

Ryomen Sukuna

Ryomen Sukuna is one of the strongest specs introduced in the update. It features powerful abilities and is designed for high-level players.

To access this spec, players must meet several requirements, including a Level 3000 minimum.

Yuji Itadori

Yuji Itadori is another spec added with this update. The moveset includes abilities inspired by his fighting style, making it a solid choice for players who prefer fast and aggressive combat.

Finger Bearer

Finger Bearer is a cursed spirit-based spec with a simpler moveset compared to the others. However, it still offers strong attacks and fits well with certain builds.


New Bosses in Reign Piece

Several new bosses were added to match the new specs.

New bosses include:

  • Ryomen Sukuna Boss
  • Yuji Boss
  • Finger Bearer Boss

Each boss drops materials used for crafting specs, accessories, or progression items.


New World Boss System

The update also introduces an extremely rare World Boss.

Key details:

  • Spawn chance: 1 in 100
  • Spawn timer: Every 30 minutes

Because of the low spawn rate, players will need to stay active on servers if they want a chance to encounter this boss.


Malevolent Shrine Raid

One of the biggest additions in the update is the Malevolent Shrine Raid, which can be accessed at Jujutsu High. The raid system allows players to fight waves of enemies and powerful bosses to obtain rare rewards. Many items required for the new specs drop from this raid. This new system encourages cooperative gameplay since raids are easier when completed with a group.


New Systems Added in the Update

Several new gameplay systems were introduced to expand progression and customization.

Stat Reroll System

Players can now reroll their stats by talking to an NPC at Jujutsu High. This system allows you to adjust your build without starting over.

Heirloom System

Heirlooms are new items that drop from powerful bosses such as:

  • Meruem
  • Gojo
  • Ryomen Sukuna

These items provide extra bonuses and can improve your character’s overall strength.

Rank System

A new ranking system is available at Sakura Isle, giving players additional progression goals.

Level Contracts

Players can accept special contracts at Jujutsu High that help with leveling and progression.


New Race and Trait

The update introduces a special race and a new trait.

King’s Vessel Race

This race is unlocked through a questline at Jujutsu High. It is closely tied to the Ryomen Sukuna content and offers unique benefits.

Disgraced One Trait

The Disgraced One trait can be rolled and may provide advantages depending on your build.


New Accessories and Cosmetics

Players can also obtain several new visual items.

New accessories include:

  • Sukuna’s Kimono
  • Yuji’s Uniform

New cosmetics include:

  • Sukuna’s Cloak
  • King’s Aura

These items allow players to customize their characters while showing off progress from the new update.


The Ryomen Sukuna update is one of the largest updates released for Reign Piece so far. With a new raid system, powerful specs, and expanded progression features, the game now offers more activities for both new and high-level players.

From unlocking the King’s Vessel race to fighting the Ryomen Sukuna boss, there is a lot of new content to explore. The increased level cap and stat cap also allow players to push their builds further while farming the latest raid rewards.

If you plan to jump into the update, start by redeeming the new codes, visiting Jujutsu High, and preparing your character for the Malevolent Shrine Raid. With enough grinding and teamwork, you will be able to unlock the strongest abilities introduced in this Jujutsu-themed expansion.
