Jujutsu Zero Summer Blade & Trials Update Guide & New Codes!

The latest Jujutsu Zero update introduces a major batch of content centered around the brand-new Summer Blade, a challenging Jujutsu Trials mode, new progression features, weapon upgrades, shop refreshes, and several quality-of-life improvements. Whether you’re a returning player or already at the endgame, there’s plenty of new content worth exploring. Here’s everything added in the Summer Blade & Trials update.

Summer Blade Is the New Limited Weapon

The highlight of this update is the Summer Blade, a limited-time weapon designed for high-level players. Unlike many existing weapons, it comes with four unique skills and features a special stacking mechanic that increases its overall damage potential during combat.

The weapon also benefits from several clan synergies. Players using the Toji Clan, Zenan Clan, or Amanoi Clan can take advantage of additional bonuses, making these clans excellent choices if you plan to build around the Summer Blade.

Summer Blade Passive Ability

One of the weapon’s biggest strengths is its stack-based passive. Here’s how it works:

• Every successful attack grants one stack.
• You can accumulate up to four stacks.
• After reaching four stacks, your next attack: Deals bonus damage. Applies a special status effect to the enemy.
• The stacking process then begins again.

This mechanic rewards aggressive gameplay while providing consistent burst damage throughout longer fights.

How to Get the Summer Blade

Obtaining the Summer Blade requires completing a special forging questline. Before starting, make sure your character is at least:

• Level 4,000

Once you meet the requirement:

1. Travel to Summer Island.
2. Speak with the Summer Forager NPC.
3. Begin the Summer Blade forging quest.

The quest requires collecting two different materials from enemies.

You’ll need:

• 80 Spring Tide
• 80 Solstice

These materials are dropped by:

• Water Sorcerers → Spring Tide
• Sun Sorcerers → Solstice

After collecting both resources, return to the NPC.

Forge Your First Summer Blade

Once you’ve gathered the required materials, you’ll receive:

• 8 Equinox Ingots

This exchange is available only once and is specifically intended to help players craft their first Summer Blade.

After obtaining the ingots:

• Exchange all 8 Equinox Ingots.
• Forge the Summer Blade.

If you’re only looking for a single copy, this one-time quest is all you need.

How to Get More Summer Blade Copies

Players wanting additional Summer Blades must use the new Jujutsu Trials feature.

Unlike the initial quest, repeat crafting relies on earning more Equinox Ingots through Trials.

This makes Jujutsu Trials the primary repeatable farming method for anyone searching for duplicate Summer Blades.

Jujutsu Trials Explained

Jujutsu Trials is a brand-new chamber-based PvE activity. Instead of exploring the open world, players fight through a sequence of combat rooms. Each chamber contains:

• Multiple enemies
• A boss encounter
• Optional bonus objectives

Clearing one chamber unlocks the next, gradually increasing the overall challenge.

Bonus Objectives

Each chamber may include additional tasks such as:

• Finish within a time limit.
• Clear the chamber while taking limited damage.
• Complete special combat objectives.

Finishing these optional challenges grants extra rewards, making them worthwhile for experienced players.

Trials Rewards

The biggest reward from Jujutsu Trials is Equinox Ingots. These ingots are used to:

• Forge additional Summer Blades.
• Continue collecting limited weapons after finishing the original questline.

Because of this, Trials become one of the main endgame activities introduced in the update.

Weapon Ailments Are Now Available

Another major gameplay feature is Weapon Ailments. Previously, ailments could only be attached to emblems. Now they’re available for weapons as well. Each ailment adds additional bonuses beyond the weapon’s normal stats, allowing players to customize builds much more effectively. Benefits include:

• Extra offensive stats
• Improved build flexibility
• More weapon customization
• Better optimization for different playstyles

This gives players another layer of progression when building powerful endgame loadouts.

Guide Book Progression System

The update also introduces a Guide Book, which acts as an in-game progression tracker. Instead of wondering what to do next, players receive organized objectives that guide them through different stages of the game. Each progression tier contains five objectives covering various activities, including:

• Choosing progression paths
• Completing quests
• Defeating important bosses
• Clearing raids
• Unlocking new content

Selecting an objective automatically highlights its location on the map, making navigation much easier for newer players.

Completing Guide Book tasks rewards useful progression materials and currencies.

New Sorcerer Strength Stat

A new statistic called Sorcerer Strength has also been added.

Rather than measuring a single attribute, this stat represents your character’s overall combat power based on:

• Equipment
• Stats
• Weapons
• Build improvements

It serves as a quick way to compare different builds and monitor overall progression without manually calculating every upgrade.

Shop Restocks

Several shops have received updated inventories.

The following vendors now offer refreshed items:

• Summer Shop
• Seed Shop
• Investigation Shop

If you’ve already purchased everything previously available, it’s worth revisiting each shop to see the newly stocked rewards.

Progression XP Changes

Players progressing beyond Level 1,000 will notice smoother leveling.

The update adjusts progression quest experience for higher-level characters, helping reduce the grind during later stages of the game.

This should make leveling through the endgame feel more consistent than before.

Lobby and Early Game Improvements

The game’s lobby has also been redesigned.

Notable changes include:

• Spawn point moved closer to the main area.
• Jujutsu Trials is easier to access.
• Several NPCs have been relocated.
• Early quests now start much closer to spawn.
• New players can begin progressing immediately after joining.

These improvements reduce unnecessary travel and make navigation significantly more convenient.

Bug Fixes

Alongside the new content, the developers addressed numerous bugs and gameplay issues.

Some of the notable fixes include:

• Fixed the Judgment power-up bar.
• Fixed Queen’s Carnage issues.
• Resolved the Shikigami count UI bug.
• Fixed interface problems caused by opening crates too quickly.
• Fixed Shrine sound glitches.
• Adjusted Jogo’s abilities during overworld raids.
• Various additional gameplay and stability improvements.

New Jujutsu Zero Code

A new promotional code is available with this update.

• Code: summerblade

Rewards include:

• 500 Cursed Crystals
• 3,500 Lumens
• 50 Clan Rolls

Redeem the code as soon as possible since promotional codes may expire in future updates.

The Summer Blade & Trials update delivers one of the biggest content expansions for Jujutsu Zero so far. The new limited weapon introduces a unique stack-based combat mechanic, while Jujutsu Trials adds a repeatable endgame activity that rewards Equinox Ingots for crafting additional Summer Blades. Combined with Weapon Ailments, the Guide Book progression system, Sorcerer Strength, refreshed shops, experience adjustments, and various quality-of-life improvements, this update gives both veteran and newer players plenty of reasons to jump back into the game. If you’re already Level 4,000 or higher, unlocking the Summer Blade should be one of your top priorities.
