Jayber Trigger Module
You need to first unlock the trigger module slot for each character. Learn how to unlock Trigger Modules in The First Descendant.
For our The First Descendant Jayber Build, you always want to use the Power Beyond trigger module. This gives us a flat 15% Skill Power Increase to all our damage, which is very powerful.
- Mobbing & Bossing: Power Beyond
Jayber Ancestor Module
Ancestor Modules can be slotted once you have acquired them. However, they are only worth it once you have an Ancestor module with good stat rolls on them.

Superconductive Cooling Units (Needed to Reroll perks): It is only worth slotting an Ancestor Module if you have good rolls on it; otherwise, it isn’t worth it.
- Ideal Positive Rolls
- Non-Attribute
- Dimension
- Duration
- Cooldown
- Ideal Negative Rolls
- Max Shield
- DEF
Ancestor Module: What to Replace and Why
To slot an Ancestor Module effectively, identify existing modules that share the same primary stat. By replacing a standard module with an Ancestor version that offers similar values, you maintain your core build while gaining its additional unique perks as a ‘free’ bonus.
- How to: Replace a standard module with an Ancestor Module that mirrors its main perk.
- The values should be close; you preferably don’t want to replace a 100% with a 30% value.
- Example 1: If your Ancestor Module provides Skill Critical Hit Rate, replace Skill Insight.
- Example 2: If your Ancestor Module provides Max HP, replace Increased HP.
- Example 3: If your Ancestor Module provides Skill Effect Range, replace Skill Expansion.
- Result: All other perks from the Ancestor Module will basically be a “freebie” and improve your build!
- Helpful Links:
As long as the Ancestor Module reaches a similar value to the one you’re removing, every additional stat on that Ancestor Module becomes a “free” bonus for your build.
Arche Tuning for Jayber
The Arche Tuning System in The First Descendant is important for every Character; it buffs your stats by a good amount.
You level up Arche Tuning in the Sigma Sector Dropoff Operation. Mutant Cells also drop there with a small chance.
For Jayber, we are going the right side and upper right side route.

How to find the Location of Reactors
Reactor drop locations change every day. Not many players know this and get confused. Now, there is a reactor search function in-game. Go to the map and press on Difficulty Level Rewards. In here, you can see where all the reactors currently drop.
Note: It is possible that not all reactor types are currently dropping. You have to come back and recheck every day.
If your specified reactor drops in an area, you go there and farm any missions and monsters (Preferably missions with lots of monster spawns). There will be plenty of reactors dropping from monsters all over the place, any monster works. It will take a while to get a good reactor!

Smooth Grapple Hook for your Jayber Build
Using the standard Grapple Hook in The First Descendant can be a pain, and it feels kinda frustrating at times. Don’t worry, there is a way better alternative that will make it a joy to use the grappling hook!
It is called the Mid-Air Maneuvering Sub Module. I use this on all my The First Descendant Builds because it improves grappling by so much.
With this Module, you can attach your Grapple Hook to anything, even air! That means you can simply aim towards the sky and Hook up your grapple hook there for guaranteed fast movement!
Here is a guide on how to get the Mid-Air Maneuvering Sub Module in The First Descendant. It won’t take a lot of effort, but it will improve your build and overall gameplay in The First Descendant.
Jayber’s Story in The First Descendant
A utility-type dealer who uses turrets. Summons turrets for assault and recovery, respectively.
Are geniuses born or made? A natural engineer, there are many hypotheses about the origin of Jayber’s ability to wield Arche specialized in electronic warfare.
One hypothesis claims that the infectious disease he suffered during his childhood stimulated his cerebral cortex, leading to a dramatic increase in intelligence. Another one claims that the drug administered to treat the infectious disease was actually an experiment conducted by the Magisters to mass produce Arche.
Despite the unfounded rumours that continue to go around to this day, he himself had no desire to learn the truth. The reason being, as merely a unit in the war, the origin of his ability was unimportant to him.
For Jayber, who was born in the infectious disease isolation ard, the life support device that let him sleep comfortably and sang nursery rhymes to him was practically his parent. Jayber grew up having a deep connection with this life support device.
When he turned 10 years old, he was able to modify the device himself to connect to an external network and study the world. The moment Jayber connected to the real world, he was able to understand why the life support device was against connecting to the network.
The world was not the happy place that Jayber had dreamed of. It was constantly being plagued by invaders called the Vulgus and threatening entities called the Colossi. He was raised by the Magisters to become a weapon of war, a Descendant with the power of Arche, to combat these threats.
After coming into contact with reality, Jayber gave up on his hoped and dreams; instead, he began to think of himself as a necessary unit for war. Even after becoming an official Descendant, this attitude did not change, and his teammates were no fans of this Descendant who was no different from a machine. However, none of this mattered to Jayber. Geniuses are neither born nor made. Because they, too, are just a unit.
