Valby Build Guide for The First Descendant

Valby is an area (AOE) damage dealer who uses her water abilities to maneuver around the battlefield, deal damage, and evade enemy fire. She’s an excellent choice for players seeking a character with strong damage output and good survivability. Due to her focus on AOE abilities, Valby excels against groups of enemies but is less effective against bosses. Mastering Valby involves understanding the nuances of her abilities and applying attack and movement strategies thoughtfully.

Valby is straightforward to play, offering high damage and mobility. She can preemptively place damage on the ground before enemies appear. However, she struggles in boss fights or scenarios where you can’t control the movement. To maximize Valby’s potential, Bubble Bullet can be used to create small puddles at its impact point. These puddles damage enemies within them over time and allow you to consume less mana while standing in them, enabling you to spam abilities almost for free when combining water and bubble tactics. Below, we walk you through a guide on the Best Valby build in the First Descendant.

How to play Valby in The First Descendant

The First Descendant Valby Character

To effectively play Valby, stand in water to conserve mana while ensuring enemies within puddles take continuous damage. Valby uses her Arche connection to water to move fluidly across the battlefield, delivering area-of-effect damage to groups of Vulgus. Additionally, she has a knockdown ability, providing extra crowd control to support her team. Her playstyle revolves around using her Bubble Bullet ability and puddles to damage enemies, recover MP, and navigate the battlefield.

Area Damage and Single-Target Damage: Valby’s toolkit is focused on AOE damage abilities, making her most effective against multiple targets. Her single-target damage depends largely on the weapon she uses. Utilize Bubble Bullet and Plop Plop to create large puddles. One skill is ranged, while the other is centered on her position. Use these skills when at a distance or surrounded to increase damage over time and sustain resources.

Movement and Speed: Valby is second only to the Bunny class in terms of speed and movement in The First Descendant. Her Laundry skill allows her to move through enemies, boost her movement speed, and create a path of water. This skill can be used both offensively and defensively.

Bosses and Ultimates: During boss encounters, keep puddles under the enemy at all times. Monitor your cooldowns and rotate skills to maintain high uptime on puddle damage. Use Laundry Bomb to pull in enemies if mobs appear during encounters.

Defenses and Survival Tips: Valby’s Clean Up ability enhances her survivability and defense while dealing a bit of damage over time. Activating it makes her completely invulnerable and increases her speed. While in this state, she cannot use other skills, but it’s perfect for escaping tight situations.

Skills

The main theme with Valby’s skills is the Laundry debuff inflicted via water. You can also create damage over time with this this debuff and gain regen standing inside it. Therefore, target enemies and stay inside water and puddles when you can. Below are all the skills for Valby:

  • Bubble Bullet – Bounces a Bubble Bullet forward to create a small puddle where the Bubble Bullet impacts and where she stands. Enemies in the small puddle take continuous damage and are inflicted with Laundry.
  • Plop Plop – Creates a large puddle where she is standing, then dives in. Vallby then pops out at a selected location in the large puddle. Enemies in the large puddle take continuous damage and are inflicted with Laundry.
  • Clean Up – Vallby becomes Liquefied. While Liquefied, she cannot take her feet off of the ground or use skills, but she can move through enemies and her Movement Speed and DEF increase. When moving while Liquefied, she creates a path of water that deals continuous damage to enemies and inflicts Laundry.
  • Laundry Bomb – Changes the weapon equipped for the Launcher. When the Launcher is fired, a Bomb is created, pulling in enemies inflicted with Laundry and dealing continuous damage.
  • Water Intake (Passive) – When using skills while standing on water, she consumes less Mana.

Best Skill for Valby

Bubble Bullet is the best skill for Valby because it does damage on impact, damage over time, debuffs enemies, and lowers mana consumption when standing in the water trail left behind. The main idea behind Valby is to debuff enemies with Laundry (water), lowering their resistances to Electric and Non-Attribute. This Laundry debuff is helpful for any player using the Thunder Cage Ultimate weapon or playing Bunny and Sharen builds.

The First Descendant - How to use Bubble Bullet - Best Valby Skill

The best way to use Bubble Bullet is at far range because the more bounce it takes, the more damage it will produce when landing on a target. The skill’s cooldown is 10 seconds but can be lowered with modules. The Materialized Mixture reactor will boost the power of Bubble Bullet and other Fusion descendant attribute abilities like Laundry Bomb.

For boss fights, use Valby’s Bubble Bullet at range for the puddle left behind. Even if you don’t hit a boss, you can step inside the water area to lower the mana (MP) abilities cost. You should fire out Bubble Bullet first, then Laundry Bomb, to transform your weapon into a massive water cannon. Then, you can shoot out bombs while in the puddle to lower your cost of damaging the boss or clearing mobs.

Lastly, Bubble Bullet Laundry debuff also reduces Chill resistance. You want to pair Bubble Bullet with Blizzard from Viessa for optimal damage combo. Using the debuff first, then Viessa’s Blizzard ultimate skill will produce massive damage to a single target or AOE. Overall, this lower cooldown, great damage, AOE, and resource-sustaining tool should be your opening attack and the focal point of any Valby build.

Bubble Bullet

  • The enemy standing in the Small Puddle receives continuous damage and becomes inflicted with Laundry.
  • When the Bubble Bullet pops, nearby enemies receive AOE damage, increasing based on the number of bounces.

How to use Bubble Bullet: Valby’s primary skill is to trigger puddles and laundry status effects. Bubble Bullet, while a single target, can hit multiple enemies in a small radius for a while, leaving a puddle that deals continuous damage. Primarily, we rely on this skill for damage and status effects. Moreover, it makes enemies vulnerable to electricity and chill, and it is useful for playing with a Bunny build or others who are buffed by those elements.

Descendant Modules for Valby Build

Frugal Mindset, Battle of Stamina, and Spear and Shield are the best modules (mods) for a Valby Build in the First Descendant. We choose Frugal Mindset because it lowers your skill cost and increases damage radius. Battle of Stamina is great because it boosts your max HP and skill duration. Lastly, you want Spear and Shield because it increases both defense and skill power. Consequently, all three of these mods together will give you incredible survivability and skill power. Thus allowing Aalby to take advantage of her damage-over-time and crowd control playstyle.

In The First Descendant, modules are essential components that enhance and customize your character’s abilities, stats, and overall performance. Modules can be acquired through questing, missions, loot drops, and vendor items. Moreover, you have limited resources to slot mods; therefore, some slots may be empty depending on your chosen setup.

Best Reactor Stats for Valby in The First Descendant

Materialized Mixture is the best reactor for a Valby build in the First Descendant because it boosts your Non-Attribute and Fusion skills. Non-attributes are your descendant attributes, and fusion increases Bubblet Bullet and Laundry. The second choice is the Materilized Phase, which buffs Non-Attribute and Dimension type, effective Plop Plop, and Laundry skills. Below is our recommendation for the best Valby reactors:

  1. Optimization Condition: Scout Rifle (Blue Beetle)
  2. Skill Power Boost Ratio
    Materialized Mixture: Boost to Non-Attribute and Fusion type
    Materialized Phase: Boost to Non-Attribute and Dimension type
  3. Bonus Conditions: Non-attribute power boost ratio and Skill critical hit rate

In The First Descendant, reactors are powerful enhancements significantly impacting a character’s abilities, stats, and overall performance. They function as core components that provide substantial boosts and unique effects, enabling players to tailor their characters to specific playstyles and strategies.

Weapons for Valby Build

The best weapons for Valby are the Thunder Cage Submachine Gun and the Afterglow Sword Sniper Rifle. Thunder Cage has a high rate of fire and an overcharge bonus. Overcharge grants the following special bonus: defeating an enemy prompts that enemy to unleash an electric shockwave, dealing firearm ATK to nearby enemies within 3 meters, with additional damage. Therefore, with Thunder Cage, you can gain even more AOE damage and boost weapon attacks as well.

The following list presents the best weapon choices for Valby Build:

  • Thunder Cage – Submachine Gun
  • Blue Beetle – Scout Rifle
  • Afterglow Sword – Sniper Rifle

Valby’s Story in the First Descendant

A dealer of continuous damage who moves around freely through her Water Arche. A terrifying torrent to her enemies, she’s always a refreshing ocean wave to her teammates.

Valleys, oceans, and lakes that are drying…As a member of Ingris Environment Watch, Valby was always saddened to see Mother Nature become polluted by war. When she traveled outside Albion on pollution investigation missions, she saw rivers in Ingris disappearing one after another. The White-night Valley, where the sun never set, was now a gulch, and the Echo Plains had long turned into a swamp because of the Vulgus Kuiper mining…

From the way things were going, would there even be a place left where humanity could live in peace if they won the war? She wondered, “Was that why?” Valby found a shimmering lake somewhere in the Vespers Woodland. Calling it the ‘Last Emerald,’ she swore to protect this small glimmer of hope. Making it a home for plants and animals so that the ecosystem of Ingris could be restored… To Valby, the Last Emerald was truly her last hope.

But in times like these, hope was such a fragile gem. On that fateful day, Valby was gazing out over the lake as usual when she encountered the Order of Truth that entered into Vespers Woodland… Having completed advanced military training, Valby fought off the Vulgus, as well as requesting support from the Descendant Corps. But the lack of an Arche teleportation device in the area meant that help was delayed, leaving Valby no choice but to defend the lake alone. However, even the lowest-ranked Vulgus was too much for a non-Descendant. After being brutally attacked, Valby was thrown into the lake.

Valby Story Contiuned

As she sank into the water, Valby thought to herself, at least she could meet her end in the bosom of the Emerald… She was grateful to the lake for letting her dream of hope, even if for a little… But in the final moments, when her consciousness began to fade, Valby could not control her instincts to survive. “I want to fight again. I want to protect this lake. No… I want to become a great ocean that will swallow up every Vulgus there is…”

At that moment, a massive wave arose from the center of the lake, devastating the surrounding area. The enemies were crushed by the immense pressure of the water and vanished without a trace. And where the lake once was, a mass of water in the shape of a human was thrashing wildly. It was Valby. At death’s door, she had awoken her Arche, and her ability enabled her to merge with the water and swim without end… She had become the Last Emerald itself.
