Best Ultimate Viessa Modules (Hard)

More Modules can be seen by scrolling horizontally.

This build is similar to our Base Viessa Build since it is the best build for both Descendants.

The build is focuses on casting consecutive skills with high Critical Hit and low cooldown. The build relies on the multiple Cooldown Reduction modules together with the Cold-Bloodedness module, which will provide you with 20% Cooldown Reduction, 20% Skill Cost Reduction, and 5% Skill Power whenever you use your Cold-Bloodedness skill.

Prioritize getting in Cooldown Reduction, Skill Damage, and survival modules, then start building Skill Range and Skill Critical Hit modules after.

Alternative Descendant Modules

Module Change Explanation
The First Descendant - Dangerous AmbushDangerous Ambush > The First Descendant - MP CollectorMP Collector Recommended for mobbing because you will often run out of MP with skill spamming
The First Descendant - Battle of StaminaBattle of Stamina > The First Descendant - Increased HPIncreased HP Gives you more survivability but decreases one tick of damage with Blizzard skill
The First Descendant - Increased DEFIncreased DEF > The First Descendant - Spear and ShieldSpear and Shield Gives you less DEF but increases your Skill Power by a good amount
The First Descendant - Emergency MeasuresEmergency Measures > The First Descendant - Skill ExtensionSkill Extension Trading some Critical Hits for one more tick of Blizzard and longer duration of Cold-bloodedness

You can substitute these modules to gain more damage or survivability, depending on which modules you have or prefer. Some of these are ideal when mobbing, like the MP Collector module.

Other Skill Modules worth mentioning are the Hypothermia and Absolute-Zero modules. These modules can substitute Cold-Bloodedness to gain damage ticks on Chill Skills; however, it would change the core aspect of the build and would require you to stack Skill Power Modifier and Singular Damage instead.

Best Ultimate Viessa Weapons and Weapon Modules (Hard)

Weapon Substat Priority
The First Descendant - Thunder CageThunder Cage • Bonus Firearm ATK (vs. Colossus)
• Firearm ATK
• Firearm Critical Rate
• Firearm Critical Hit Damage
• Weak Point Damage

The First Descendant - ClairvoyanceClairvoyance
(Optional)
• Bonus Firearm ATK (vs. Colossus)
• Firearm ATK
• Firearm Critical Rate
• Firearm Critical Hit Damage
• Weak Point Damage
• Rounds Per Magazine

The Thunder Cage is Ultimate Viessas go-to weapon due to its high stats with good mobility and AoE burst capabilities. This weapon shines in every activity and mission you would encounter in the game.

An optional weapon you can consider is the Clairvoyance, with its unique ability to reduce enemy Chill Resistance by 20% and Action Speed by 70%. This works great with Ultimate Viessa since it will increase the damage of all of her skills and will also prevent enemies from walking out of Blizzard's range.

Best Weapon Modules

More Modules can be seen by scrolling horizontally.

For Thunder Cage's weapon modules, get those that would give you Firearm ATK, Critical Hit Rate and Damage, and Weak Point Damage to increase your overall weapon damage. Chill Enhancement is the default module that goes with Ultimate Viessa, but you could replace it with other enhancement modules to match the enemy's weakness.

The same modules could be slotted for Clairvoyance; however, do note that you will have to level up modules again as the weapons mentioned have different bullet types. You'd also want to have Superconductivity Charge replace Fire Rate UP to have a longer firing time, allowing you to have higher uptime on the unique ability.

The First Descendant - Polar Night ProcessorPolar Night Processor • Max Shield

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

The best Reactor for this build is a Frozen Mechanics Reactor, which boosts your high-damaging skills, Blizzard and Ice Shards. For substats, we recommend prioritizing Additional Skill ATK When Attacking Colossus to gain roughly about 20% extra damage against Colossus. Aside from that, any other matching utility or offensive substats would be ideal.

The best External Component set for Ultimate Viessa is the Polar Night Set. The set bonus will give you up to 60% Skill Critical Hit Damage and 17% Firearm Critical Skill Damage, which you can easily gain even when fighting bosses. This, together with the 6% Chill Power, makes the set better than the highly regarded Slayer Set.

How to Play Ultimate Viessa


Cast Cold-Bloodedness Before Casting Skills

Always cast your Cold-Bloodedness skill before casting your other offensive skill to take advantage of the Cold-Bloodedness module. You can determine the duration of Cold-Bloodedness by checking a green icon located next to your character.

Recast Cold-Bloodedness before the buff ends to take advantage of the 20% Cost Reduction when recasting your buff.

Charge Clairvoyance to Level 2 or Higher

If you have Clairvoyance, make sure to always hit enemies with the level 2 or 3 charge to activate the weapon's unique passive. As long as you're firing the weapon, the debuff will continue to reapply itself.

You can determine a beam rifle's charge by looking at the bars on top of to the ammo indicator. Make sure you have the Superconductivity Charge module slotted in for faster charges.

Ultimate Viessa Exclusive Equipment

Ultimate 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. In light of all this, the Magisters have concluded that the equipment was likely used in religious rituals by the Ancestors. If so, which gods did they worship, and why did those gods abandon the Ancestors?
