Boosting the Skill Power of your Non-Attribute and Dimensional Skills does affect the damage output of your turret, but it does not significantly impact the course of the fight during Void Intercept Battles. With this in mind, the main focus of this build should be to stack defensive stats to increase the durability of all your turrets and to enhance the healing capabilities of your Medical Turret. By using these modules, your HP and defense will be high enough to tank all of the boss's attacks and provide excellent healing for your team.

The First Descendant - Second WindSecond Wind > The First Descendant - Skill SimplificationSkill Simplification increases your Skill Power Modifier but lowers your Max MP.
The First Descendant - Iron DefenseIron Defense > The First Descendant - Dimension MasterDimension Master Improves the damage output of your Assault Turret.
The First Descendant - Medical SupportMedical Support > The First Descendant - Dimension SpecialistDimension Specialist Removes HP healing in exchange for more Assault Turret damage.

For clearing mobs, you can replace your defensive and HP healing modules with more offensive ones to enhance the effectiveness of your Assault Turrets. Since enemies can drop HP consumables, you won't need to heal yourself or your team at all. Instead, you can focus on increasing the damage of your turrets to ensure that enemies die from a single shot. This way, you can defend an area with ease using your Assault Turrets, paired with Turret Engineering.

Best Jayber Weapons and Weapon Modules (Hard)

Weapon Substat Priority
The First Descendant - TamerTamer • Bonus Firearm ATK (vs. Colossus)
• Firearm ATK
• Recoil
• Rounds per Magazine

For this build, you will primarily use the Tamer due to its high fire rate and large magazine capacity. Since nearly all of your descendant modules will focus on increasing your defense and HP, you will be able to attack the boss continuously without worrying about dodging incoming attacks. This playstyle addresses the Tamer's main weakness: the significant decrease in movement speed for dodging.

Best Weapon Modules

More Modules can be seen by scrolling horizontally.

When using the Tamer, your main goal is to increase the Fire Rate, Firearm Attack, and Attribute attack to enhance your overall damage against enemies. Since your base Critical Hit Chance will be extremely low, you can disregard it entirely. Instead, focus on expanding your Magazine Capacity and improving Recoil stats. Do note that you can replace Electric Enhancement with other module attributes depending on the boss' weakness.

Note that External Components with set bonuses have fixed main stats.

For the Reactor, you can use a Materialized Phase Reactor since you will rely on your Assault Turret as a secondary source of damage. Additionally, make sure to acquire Skill Duration and Skill Range sub-stats to enhance the effectiveness of your Medical Turret.

As for the External Component, it is ideal to obtain set effect bonuses to improve the performance of the build on descendants. However, for Jayber, this is not necessary since you do not need to increase your skill power and firearm attack. It is better to simply stack HP and DEF using Support External Components, which directly increase Jayber's base stats, resulting in a significant boost to your descendant modules.

Jayber Playstyle Tips

Jayber Playstyle Tips

Refresh Turret Duration Using Turret Engineering

During fights, don’t wait for the turrets to expire and then re-summon them. Instead, use Turret Engineering to refresh their duration. With the right Modules, Reactor Sub-stats, and enough Skill Cooldown, you can maintain 100% uptime on your turrets using Turret Engineering.

Do Not Stand Too Close to Your Turret

Even though your turret is extremely durable, it is still recommended that you avoid standing too close to ensure at least one of you remains healthy during the boss's AOE attacks. Stay within the turret’s range to benefit from the Medical Turret’s healing, but be prepared to move away immediately if you draw the boss’s attention.

With this build, you will fully utilize your Assault Turret to kill enemies and secure areas. Focus on building up Skill Power and Non-Attribute stats to boost turret damage, along with HP and Defense Modules for increased durability, as they scale with your Descendant's HP and Defense.

Including Cooldown Reduction Modules will allow you to frequently reposition your turret during missions or while defending areas. Additionally, summoning a new turret replenishes its HP, so you can use it as a tank to draw enemies away from you.

Using this build, your weapon of choice will be the Tamer due to its High Fire Rate, which is extremely useful when dealing with large groups of enemies or against Void Intercept Battles.

Because of this, your main goal is to increase your Magazine Capacity to make your weapon more effective, especially with Attribute Status Effect. It is also highly recommended to invest in Recoil Modules to control your shots when targeting Weak Points.

Best Jayber Reactor (Normal)

Reactor Stat Priority
Materialized Phase Reactor ImageMaterialized Phase Reactor ・Dimension Skill Power Boost Ratio

It is best to improve the stats and effects of your Turrets, as they are the main skills you will use throughout the fight. It is highly recommended to use a Materialized Phase Reactor since both your Assault Turret and Medical Turret are tagged as Non-Attribute and Dimension Skills. Although Multi-Purpose Gun and Reactivate can be useful, they are very situational and won't be used as much.

Jayber Exclusive Equipment

Arche-Sensitive Electronic Network System

Developed to fully utilize Jayber's ability to send and receive electronic signals using his Arche, this system is a formidable electronic warfare device designed to collect all electronic signals within the range of Jayber's Arche and relay them directly to his brainwaves, allowing his response time to be less than 0 ms. In particular, due to their unique versatility and responsiveness, dedicated turrets utilizing this system are used in various battle missions. The use of multi-purpose guns that amplify Arche signals gives him an advantage, even against large groups of Vulgus.

Just for clarification. You can't put both Skill Simplification and Dimension Specialist in for the Mobbing variant. They're both Attack modules.
