Here is a quick list of the strengths and weaknesses of the Viessa Build for The First Descendant.

How to Play Viessa in the First Descendant

This Viessa Build achieves a 100% Critical Hit Rate and a 100% uptime on her fourth skill , Blizzard.

In this section, we are going to take a look at how Viessa works in The First Descendant. Viessa excels at dealing mid range AOE damage and also has great single-target damage thanks to her fourth skill that deals so much damage. Learn about her skills in detail in the Viessa’s Skill Explanation section. Viessa’s Transcendent Modules are also exceptional!

Viessa is a skill-based Descendant. Meaning that your main damage comes from skills, not from weapons. 

Viessa also has an amazing arsenal of Transcendent Modules, which are actually useful! While most builds will use Absolute-Zero (Ultimate Viessa only), it is recommended to test out her other unique mods too!

Viessa’s AoE Capabilities: Freeze Anything!

Viessa’s strength lies in her ability to deal massive AoE damage in a mid-sized radius. Additionally, her first skill Frost Shards can be spammed as the cooldown is less than a second, and her third skill Cold Snap also recharges insanely fast.

Lastly, her fourth skill , Blizzard, deals insane AoE damage, deleting almost any monster and boss off the map in seconds.

• Check out the Viessa Mobbing Build for more information on how to build the perfect module setup to maximize her damage and range!

Viessa’s Single Target Damage: Maximum Burst!

You might think Viessa’s single-target damage is mid because she mostly has AoE damage skills. However, her fourth skill , Blizzard deals so much damage that it is an excellent single-target skill too!

Check out her Viessa Bossing Build to see how you can destroy Colossus bosses within seconds!

Viessa’s Equipment: Make Or Break It!

To unlock Viessa’s full potential, you need the right Weapons, Reactors, and External Components:

• Weapons: While you can use a powerful weapon with her to deal damage, they are mostly used as “stat stick” to boost her skills further. See the Best Weapons for Viessa section.
• Reactors: Selecting the right reactor can drastically boost your damage. Check out the Best Reactors for Viessa section.
• External Components: These are critical for survivability. Properly configured, they double or triple your HP and DEF. Learn more in the Best External Components for Viessa section.

Building a top-tier The First Descendant Viessa Build requires not only the right modules but also optimized weapons, reactors, and components.

Best Viessa Builds Overview for The First Descendant

 

All Viessa build setups require an Energy Activator to increase the Module Capacity. We also have an in-depth guide on how to farm Energy Activators in The First Descendant. Additionally, you will need plenty of Kuiper Shards and Gold to increase Module Levels. Here are the Top 3 Kuiper Shard farm spots!

Equipment: I will cover Weapons, Reactors, and External Components in the Viessa Equipment section. To maximize the power of any build, you must get the correct items!

• How to get Modules: Read the Module Farming section.
• 85 Module Capacity How? Read the basics Module section.

Viessa Mobbing Build

• Mobbing Build Type: Any hard difficulty mobbing content
• Mobbing Build Focus: Optimized for AoE damage, max range and speed!
• Playable on: Ultimate Viessa

This is our Viessa Mobbing Build that is used in any difficult content that requires AOE damage. Here, we particularly increase her skill damage and range. Additionally, because we want to spam her skills we will use skill cost reduction and skill cooldown modules.

We use the Absolute-Zero Transcendant Module, which is exclusive to Ultimate Viessa for this setup. This turns all her skills into singular type. The module increases all our skill power modifiers. Additionally, you also get an extra 20% skill critical rate, making it easy to get near to or to a 100% crit rate.

• Note 1: If you want more HP, you can slot the Increased HP module instead of Maximize Conservation.
• To get to a 100% uptime on your fourth skill Blizzard, you will need to have the correct Reactor, External Components, and Arche Tuning setup.

Viessa Mobbing Build Modules Explanation:

• Absolute-Zero: Changes the passive into Absolute-Zero. Adds extra critical hit rate and Frostbite.
• MP Conversion: – Skill Cooldown, – Max MP
• Maximize Conservation: – Skill Cost, – Skill Power Modifier
• Focus on Singular: + Singular Skill Power Modifier, – Skill Cooldown
• Nimble Fingers: – Skill Cooldown

Trigger and Ancestor Modules for the Viessa Build

Trigger and Ancestor Modules are also part of the module category, but they are a special type of module that are harder to unlock and acquire.

• Trigger Modules: Go into a special slot. Unlock special buffs and unique effects.
• Ancestor Modules: Go into a normal module slot. Enhance the build by adding additional stats.

Viessa Trigger Modules

Trigger Modules need to first be unlocked. Learn how to unlock Trigger Modules in The First Descendant.

For Viessa, we want to be using the Power Beyond Trigger Module. This enhances our skill power by 5-15%, and also applies the tow effect to enemies.

Ines 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.

Viessa Ancestor Module: Hunter’s Resolution

It is only worth slotting an Ancestor Module if you have good rolls on it; otherwise, it isn’t worth it.

• Ideal Positive Rolls
  • Chill
  • Singular
  • Skill Critical Hit Damage
  • Skill Cost
• Ideal Negative Rolls
  • Max Shield
  • DEF

Arche Tuning for Viessa

The Arche Tuning System in The First Descendant is important for every Character; it buffs your stats by a good amount. For The First Descendant Viessa, we are focusing on the right and upper right section. You level up Arche Tuning in the Sigma Sector Dropoff Operation. Mutant Cells also drop there with a small chance.

Note: We don’t activate the yellow Enhanced Skill Power node on the right side because it doesn’t benefit us a lot. It is more important to pick up the extra Crit Rate and Crit Damage!

We use the Frostbite Vulnerability Mutant Cell. This allows us to boost our Skill Power even further! There is also Chill Cohesion Mutant Cell that is decent, but remember this only buffs Chill Damage whereas our Frostbite Vulnerability buffs Skill Power and thus affects Chill and Singular!

• Mutant Cell: Frostbite Vulnerability

Viessa Equipment Overview in The First Descendant

Equipment is the cornerstone of any successful The First Descendant Build. For Viessa, having the right setup can mean the difference between dominating a dungeon and falling short. This section breaks down the essential equipment types: Weapons, Reactors, External Components, and Transcendent Modules, and explains how they maximize her power.

Viessa Equipment Guide

Equipment Type	Importance	Key Benefits
Weapons	Not very important because Viessa is a skill-based Descendant. Only used as a “stat stick” to get Sprint Speed and Grapple Hook Recharge or other weapon effect buffs!	Sprint Speed and Grapple Hook speed increase.
Reactors	Essential for boosting skill damage. Incorrect reactors severely reduce effectiveness.	Enhances skill potency. Ensures Viessa’s abilities perform at peak levels.
External Components	Arguably the most impactful equipment. Dramatically improves survivability and utility. Set Buffs with 2/4 pieces.	Quadruples stats like HP or DEF. Adds utility like MP recovery. Enables effective performance in high-difficulty content. Core System Enhancements.
Inversion Reinforcements	Adds further buffs to your build.	Perks that can make a difference in build power.
Transcendent Modules	Unlocks advanced playstyles. Essential for specialized builds.	Significantly boosts skill efficiency and power.

Best Weapon for the Viessa Build in The First Descendant

Below you can find the Top 3 Weapons for Viessa in The First Descendant.

Viessa is a skill-based Descendant and therefore, her weapon isn’t that important! However, we can use a weapon as a “stat stick” to get more sprint speed and faster grapple hook recharge (Secret Garden).

Viessa Secret Garden Weapon Cores

Top 3 Weapons for Viessa

Top 3 Mobbing Weapons for Viessa

Weapon	Category	Key Features	Why It’s Great for Viessa
Secret Garden	Tactical Rifle	Has the best weapon core slots for a “stat stick” weapon. Stat stick: 2x Sprint Speed, 1x Grapple Hook or simply 3x Sprint Speed.	Increases her sprinting speed by a lot.
Albion Cavalry Gun	Machine Gun	Insane ST damage. Stuns enemies.	Insane ST damage and stuns nearby enemies. Fast Fire Rate Overall High DPS Weapon Can be used for both AoE and Single-Target
Restored Relic	Launcher	Guided Rounds Cluster Bombs	This is a powerful rocket launcher that fires guided rounds that explode into clusters to hit even more enemies! You won’t even really have to aim because the weapon has homing missiles.

 

Other Useful Weapons

Other Useful Weapon Options for Viessa

Weapon	Category	Key Features	Why It’s Great for Viessa
Voltia	Beam Rifle	Instantly destroys Anti-Void Shields and Arch Barriers. Electrocutes nearby enemies.	Best weapon to instantly destroy Anti-Void Shields and Arche Barriers, nothing even comes close to it. A must-have in your group if you are doing Void Vessel Operation runs!
Thunder Cage	Submachine Gun	Everyone has this weapon from the main story (easily accessible) “Newbies Best Friend” Electric Shockwaves	While this isn’t the best weapon out there, it is easily accessible. Deals good AoE damage.

Best Reactor for Viessa in The First Descendant

Selecting the best reactor for Viessa in The First Descendant can significantly enhance her abilities, allowing you to maximize her effectiveness in various scenarios. Not only does the reactor determine your skill damage, but it also gives additional secondary benefits through modifiers. These are often hard to get and take time to grind out!

All our skills have the chill damage type. Additionally, because we use the Absolute-Zero Transcendent Module, our skills all turn singular. So we need to select a reactor with Chill + Singular!

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!

Best External Components for the Viessa Build

With Viessa, you want to combine two different External Component Sets called Ascending Armory and Hunter set.

• The Ascending Armory Set is useful because it gives us extra Skill Cost reduction.
• The Hunter Set gives us extra Skill Cooldown reduction.

Additionally, External Components now also have core slots; it is recommended to slot Max HP and DEF cores.

Viessa Build Best External Components

External Component Part	Base Stats	Selective Best Stats	Cores
Ascending Armory Auxiliary Power	Max HP	Max HP MP Recovery Out of Combat	Max HP DEF
Hunter Sensor	DEF	Max MP MP Recovery in Combat	Max HP DEF
Ascending Armory Memory	Max HP	MP Recovery Modifier DEF	Max HP DEF
Hunter Processor	Max HP	Max Shield Shield Recovery Modifier	Max HP DEF

Note: You can replace one or two DEF cores with attribute resistance if you fight against specific enemy types.

Inversion Reinforcements Setup for Viessa

You can find the Inversion Reinforcements in the inventory, located on the bottom left side. This changes with every new season and needs to be leveled up again. You level up Inversion Reinforcements by doing any activity. However, the fastest way to advance it is by completing Disrupt Invasion (max 4 daily) in the dungeon terminal with the red dungeons.

At max level, you have unlocked everything. While the last perk is always active in each row, you can only slot three additional perks at the bottom. Here is what you want to prioritize:

• Hunt: Pick Arche Circulation Tactic.
• Attribute: None.
• Recovery: Selective Neurostimulation.
• Survival: Deploy Hardened Shell.
• Season: None.

All Viessa Transcendent Modules Explained

First, let us look at the full list of all Transcendent Modules for Viessa in The First Descendant. It is important to note that not all of the modules will be used. Some are more effective than others!

Module Name	Module Description	Best In Slot
Cold Snap Watch	Creates a Cold Snap zone in front that remains for a certain period of time. Enemies entering the Cold Snap zone are inflicted with Ice Shackle and suffer continuous damage.	Not used

The First Descendant Viessa Skills Explained

In this section, we are going to explain the skills available to our Viessa Build in the First Descendant, how each skill works and the best ways for you to use them.

Icon	Skill Name	Description
	Frost Shards	Fires Frost Shards to damage enemies and deal AOE damage to nearby enemies. Inflicts Ice Shackle.
	Frost Road	Increases Movement Speed and Shield, and creates Ice Sheets on the ground that inflict Ice Shackle.
	Cold Snap	Deals Chill damage to enemies in front of Viessa and inflicts Ice Shackle.
	Blizzard	Creates a Blizzard that deals continuous damage, debuffs DEF, inflicts AoE damage and Ice Shackle.
	Ice Sphere (Passive)	Inflicting Ice Shackle creates an Ice Sphere that flies to another nearby enemy, dealing AoE damage and inflicting Ice Shackle.

Frost Shards

Fires Frost Shards to damage enemies and deal AOE damage to nearby enemies. Inflicts Ice Shackle.

Frost Shards Skill Description:

• Chill – Fusion
• Fires Frost Shards to deal damage to hit enemies and AoE damage to nearby enemies.
• Inflicts Ice Shackle on hit targets.

How to use Frost Shards:

Frost Shards is Viessa’s most basic skill, and it’s available from level 1. Despite this, it’s quite powerful thanks to its low cooldown and ability do deal considerable damage, both single-target and AoE damage too. It also applies the Ice Shackle debuff, reducing the Movement Speed of enemies. Ice Shackle can be stacked up multiple times to increase the effect and duration.

Frost Road

Increases Movement Speed and Shield, and creates Ice Sheets on the ground that inflict Ice Shackle.

Frost Road Description:

• Chill – Fusion
• When cast, grants Frost Road for a period of time.
• Frost Road increases your Movement Speed and Energy Shield, and creates Ice Sheets where Viessa walks.
• Enemies who touch the Ice Sheets are inflicted with Ice Shackle.

How to use Frost Road:

Frost Road is a handy mobility and defense skill that also helps to put the Frost Road debuff on enemies more often. It’s probably the most low-impact out of all Viessa’s skills, but it’s still quite useful for quickly moving around while slowing your pursuers.

Cold Snap

Deals Chill damage to enemies in front of Viessa and inflicts Ice Shackle.

Cold Snap Description:

• Chill – Fusion
• Spews Chill damage in front of you.
• Inflicts damage and Ice Shackle on enemies who come into contact with the chill.

How to use Cold Snap:

Cold Snap is another great AOE skill for Viessa that also inflicts two levels of Ice Shackle on enemies. The cooldown is really quite short for such a powerful AOE skill, so we strongly recommend using this as often as possible to maximise your damage output.

Blizzard

Creates a Blizzard that deals continuous damage, debuffs DEF, inflicts AoE damage and Ice Shackle.

Blizzard Description:

• Chill – Tech
• Creates a Blizzard that remains active for a period of time.
• Enemies engulfed by the Blizzard receive continuous dmaage, become inflicted with Ice Shackle, and their DEF decreases.
• When the Blizzard disappears, it inflicts AoE damage and Ice Shackle on nearby enemies.

How to use Blizzard:

Blizzard is a very powerful AoE skill with a fairly large radius, allowing Viessa to deal damage to large groups of enemies at the same time. It will also put a lot of Ice Shackle stacks on the enemies, considerably debuffing their move speed.

Unlike the previous skills, Blizzard has a fairly long cooldown, so it’s best to save it for situations where it will envelop many enemies. However, don’t be too reserved with Blizzard either, there’s little point having such a good AoE skill if you only use it once or twice per game.

Ice Sphere (Passive)

Inflicting Ice Shackle creates an Ice Sphere that flies to another nearby enemy, dealing AoE damage and inflicting Ice Shackle.

Ice Sphere Passive Description:

• Chill – Tech
• Upon using a skill to have an enemy enter a certain Ice Shackle stage, creates an Ice Sphere that flies around nearby.
• The Ice Sphere that is created flies at a nearby enemy, dealing damage to the hit enemy and AoE damage to nearby enemies.
• The hit target is inflicted with Ice Shackle.
• Ice Shackle decreases the enemy’s Speed, and increases in stage when the effect stacks. When the stage increases, the Speed reduction and duration both increase. However, the Speed reduction does not apply to certain monsters, including boss monsters.

How to use Ice Sphere:

Ice Sphere is a passive skill, which means it is always active. It’s a handy way of dealing extra damage, since when you apply Ice Shackle with one of your skills, an Ice Sphere will be created that deals extra damage to a nearby enemy. This also effectively makes the Ice Shackle effect stronger, as it indirectly deals damage rather than just being a movement speed debuff.

How Modules Work in The First Descendant

Modules are the bread and butter of all The First Descendant Builds. There are a few important things to remember about modules. This is for both Descendant and Weapon Modules.

While most builds require you to increase Module Capacity with an Energy Activator (you get two for free), they won’t require you to reduce the Module cost with Crystallization Catalyst. However, if you want to truly min-max a build, you will need plenty of these Catalysts.

1. How to increase your Module Capacity
2. Module Levels and Cost
   1. Kuiper Shards & best way to farm!
3. Reduce the cost of Modules
4. How to farm Modules

How to Increase Module Capacity

You get a base of 45 Modules for every Descendant character. And you can increase this up to 85 currently. First off, always slot a Sub Attack Module (Slot 7). When you increase this to the max level you will get an additional 10 Module Capacity. if you use a Crystallization Catalyst on the Sub Attack Module, you even get 15 extra slots. You will see this in the setup below.

Additionally, you can use an Energy Activator to increase your Module Capacity by another 20. However, these are fairly hard to farm, only use them on your best Descendants.

Lastly, increasing your Mastery Rank will also increase Module Capacity. Rank 1 gives you 25 Module Capacity, Rank 20 gives you 50 Module Capacity. That is how we reach the 80 Module Capacity that you see on most builds.

1. Slot a Sub Attack Module (and max it out to get +10 capacity, crystallize it for +15)
2. Use an Energy Activator (2o extra capacity)
3. Increase Mastery Rank (25 base capacity, max 50)

Weapons: Basically the same, but because you don’t have Subattack Modules, the Energy Activator gives you 30 instead of just 20 extra capacity.

You can also read my in-depth guide on how to increase Module Capacity in The First Descendant if you need more information. Or my Best Energy Activator Farm Spots and our Best Crystallization Catalyst Farm Spots. I tested all of the grind spots by myself and have already farmed plenty of these items with this method.

Module Levels and Cost

Modules can be enhanced (leveled up) with Kuiper Shards in The First Descendant. Enhancing Modules increases their power. At higher levels, the power will increase way more than at lower levels. Therefore it is always recommended to max out the most important Module first.

Here is an example of a must-have Module called Increased HP for our Descendant. You will notice that we start at 22%, but at the max level, we get a whopping 218.5% increase in health!

Transcendent Modules are the exception; they decrease Capacity Cost with higher levels!

For an in-depth overview, please visit our How to Level Up Modules in The First Descendant guide.

How to Farm Kuiper Shards

Kuiper Shards are used to level up Modules. We have a guide on the Top 3 Kuiper Shard Farming Locations in the First Descendant. We explain how to most efficiently farm Kuiper Shards (300-500k/hour) and show the amount you need to level up mods. As a summary, to max out a Module you need:

• Normal Modules: 103’100 Kuiper Shards
• Rare Modules: 206’200 Kuiper Shards
• Ultimate Modules: 309’300 Kuiper Shards
• Transcendent Modules: 515’500 Kuiper Shards

Always max out the most important Modules first, we will showcase the order below.

How to Reduce the Cost of Modules

To reduce the cost of Modules you need Crystallization Catalysts in The First Descendant. These require a lot of time investment, most builds won’t require you to get many if any at all (Budget Setup). But if you want to completely min-max you need to get plenty of them as technically, every slot can have a specific socket type to half the cost.

Modules have Socket Types. Our Increased HP Module has the Cerulean Socket Type.

• Module: Increased HP
• Socket Type: Cerulean

This is important because if we place our Increased HP Module in the fitting Socket Type, it will half the cost of the Module!

How to farm Modules in The First Descendant

Most The First Descendant Modules can be acquired fairly easily, but the higher-quality ones (Ultimate, Transcendent) are more tedious to obtain. Here is the easiest process to farm Modules quickly.

Open Map > Swap to Access Info > Select Modules

Here, you can find all Modules and their drop locations. If a module drops from several locations, it is recommended to select drop locations with higher drop chances.

There isn’t really much more to this. Simply check the location and go farm. Normal and Rare quality Modules have 30-50% drop chances in most cases. Ultimate ones range around the 5% mark and Transcendent ones can be a tough cookie with around 2% drop chance.

We will list the best farming location of modules in the next step of the guide.

Smooth Grapple Hook for your Viessa 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 definitely improve your build and overall gameplay in The First Descendant.

Viessa’s Story in The First Descendant

A debuffer who uses Chill at will. She uses Chill to freeze enemies in place, unleashing Cold Snap-like attacks as she weaves her way between them. 

Hailing from Albion’s underbelly, Viessa was a runner for a smuggling gang that brought in banned goods from the old, abandoned lands. During those years, Viessa was known for her ability to being in items that were more luxurious and expensive than what the other gang members brought in.

Viessa’s sphere of activity was a city that was frozen a century ago by a Colossus called the DeadBride. The place was eerie, filled with frozen corpses and the fallen Colossus, but items deemed expensive have been preserved, remaining intact. Moreover, because of the cold, the other gang members couldn’t even get near it. But for her, it was her own paradise; she couldn’t understand why everyone would shiver so much in the cold.

But this paradise turned into a cold hell overnight. The Colossus DeadBride, which was thought to be destroyed, was simply lying dormant, and the slight change in temperature caused by Viessa’s presence awakened it. In the end, Viessa was forced to fight the Colossus. She was barely able to defeat it, thanks in part to the Descendant Corps, who joined her and were deployed after an anomalous energy generation had been detected. Of course, their encounter was awkward, to say the least.

5 years? 10 years? Viessa let out a frosty sigh as she contemplated her sentence in the Albion prison, but for the second time that day, she experienced something she never thought would happen in her life. Her sentence? To join the Descendant Corps. Viessa’s peculiarities piqued the interest of the Maigisters, who conducted an Arche Factor test on her and discovered that she was indeed a Descendant.

For the first time in her life, Viessa broke out in a cold sweat, but quickly regained her composure. Become a Descendant? Beats being in a prison. No biggie, let’s give it a shot.

Viessa’s Exclusive Equipment – Emission-type Arche Battlesuit “Absolute-Zero”

Discovered long ago in an Ancestors’ facility with a temple-like appearance, this Ultimate equipment is designed from top to bottom for emission-type Arche users. Specialized gloves on the wrists connect directly to the user’s veins via nanoparticle injection tubes. A helmet-type computing device calculates the Arche concentration in the blood in real time to aid in the efficient and powerful use of Arche abilities. Interestingly, the equipment was found in a temple-like place, and its appearance is reminiscent of priestly robes.

They believed in something else, which is probably why they all perished.” – Viessa
