Best Jayber build in The First Descendant: Skills, Weapons, Reactor & Modules

Jayber is an ideal character in The First Descendant for those who want to take on a utility role rather than blast opponents with overwhelming firepower. After hours of testing, we have found a brilliant build players can use to dominate.

Jayber is all about support in The First Descendant, mainly by placing his deadly turrets in strategic locations to lay down a hail of bullets or to provide healing buffs.

In the right hands, he can be deadly and is one of the most versatile characters you can use in the game. He’s near the top of our tier list and shines when you’re using the best build.

The First Descendant Best Jayber Build – Recommended

Best Jayber Skills

After experimenting with Jayber, we found the best way to play was to not stick to one Active Skill but to utilize a selection of them.

You can use a Medical Turret to heal your teammates when needed, but when not healing, we found that the Assault Turret was the most reliable. This keeps the enemy pinned down and makes up the core offensive gameplay for Jayber.

Using both the Assault Turret and Medical Turret at the same time is a great way to get the best out of Jayber’s Passive Skill known as Turret Sync. This ability allows Jayber’s Attack power to increase when both forms of Turret are active.

Therefore, we’d recommend always finding a way to use both Medical and Assault Turrets in battle, even when healing teammates isn’t immediately required.

All skills

These are all the skills Jayber has available in the game:

• Turret Sync (Passive) – ATK increases when the assault turret and medical turret are both summoned.
• Assault Turret – Summons an assault turret to attack the enemy. If enhanced, it launches attacks into nearby area.
• Medical Turret – Summons a medical turret to heal allies and distract enemies. If enhanced, it restores Mana.
• Multi-Purpose Gun – Changes gun to a Multi-Purpose Gun. If hit by a Multi-Purpose Gun, the turret enters an enhanced state.
• Reactive – Recalls all summoned turrets and inflicts powerful damage to nearby enemies. After using Total Recall, you enter the Overhaul state, where turrets are summoned in their enhanced states.

Best weapons for Jayber

The best weapons available to Jayber are as follows:

• Enduring Legacy (Machine Gun)
• Afterglow Sword (Sniper Rifle)
• Nazeistra’s Devotion (Hand Cannon)

The Enduring Legacy is a powerful and reliable weapon for Jayber and will help you keep enemies at arm’s length. What you want to do is for enemies to back off so that your Turrets can take them out, and this machine gun is a great way to encourage this.

You can also use Nazeistra’s Devotion to quickly land powerful shots on enemies who get too close or are panicking while avoiding your Turrets. This powerful hand cannon only takes a shot or two to fall an enemy, who’ll likely be too distracted by your Turrets to realize what your own gun can do.

If you’re at a safe distance, sniping enemies with the Afterglow Sword can also be a clever strategy. Taking potshots at enemies who avoid coming near you because of your Turrets can make you a thorn in their side and drive them toward the players with bigger guns.

Best Reactor for Jayber in The First Descendant

When selecting your Reactor, it’s important to add one that gives you the most benefit based on your Active and Passive Skills.

As Jayber is a Non-Attribute character, pick a Materialized Phase/Singularity Reactor to maximize Jayber’s Assault Turret, Medical Turret Active Skills, and Turret Sync Passive Skill.

Choose the first Materialized Phase Reactor you find and upgrade it when a more powerful one comes along. There isn’t any specific one you need to pick but stick to this type.
