Best Valby Modules (Hard)

More Modules can be seen by scrolling horizontally.

With this build, you want to maximize the effects of all your abilities by expanding the range and increasing the duration of the puddles you create. You will also lower their cooldowns with modules for consistent spamming, ensuring a 100% uptime on your Laundry debuff.

Additionally, since Supply Moisture can drastically improve your Skill Critical Hit Rate, you will pair it with modules that provide Skill Critical Hit Damage and Skill Critical Hit Rate to improve your clear speed.

Modules Guide: List of Modules

Descendant Module Substitutes for Bosses

Module Change			Explanation
Veteran's Tactics	>	Lethal Infection	Gain Skill Power Modifier when landing Firearm Critical Hits.
Skill Expansion	>	MP Accelerant	Reduces the puddle radius in exchange for increased Skill Duration and Max MP.
Emergency Measures	>	Time Distribution	Lowers your Skill Critical Hit Chance in exchange for more HP and Skill Cooldown.

For boss fights, you can adjust your modules accordingly to focus more on extending their duration and reducing their cooldown to maintain the Laundry debuff, instead of increasing the radius of your abilities as you won't need to cover a large area with puddles when facing a single enemy.

Your main role during void battles is to spam your abilities for nuke damage and apply the Laundry debuff to lower the boss's Electric and Non-Attribute Resistance.

Best Valby Weapons and Weapon Modules (Hard)

Weapon	Substat Priority
Thunder Cage	• Attribute Status Effect Trigger Rate • Firearm ATK • Firearm Critical Hit Damage • Electric ATK

Since your Laundry debuff lowers the Electric Resistance of all enemies hit by your abilities, the best weapon you can equip is the Thunder Cage due to its unique ability, Overcharge. This unique passive ability gives you a set chance to discharge an Electric Shockwave to all nearby enemies when you defeat an enemy.

Best Weapon Modules

More Modules can be seen by scrolling horizontally.

Because of the Thunder Cage's high base Critical Hit Rate, pairing it with the Supply Moisture module makes this weapon exceptional, achieving close to a 100% Critical Hit Rate with these modules. To fully utilize your high Critical Hit Rate, you should also stack Critical Hit Damage to increase your critical multiplier for massive damage.

Best Valby Equipment (Hard)

Equipment	Substat Priority
Materialized Phase Reactor	• Skill Cooldown • Skill Duration Up
Slayer Auxiliary Power	・Max HP ・Fire Resistance ・Kuiper Shard Drop Rate Increase Modifier ・Module Drop Rate Increase Modifier
Slayer Sensor	・Max MP ・MP Recovery In Combat ・Chill Resistance ・Consumable Drop Rate Increase Modifier
Slayer Memory	・DEF ・Electric Resistance ・Shield Recovery In Combat ・Ecive Search Radius Increase Modifier ・Firearm Proficiency Gain Modifier ・Gold Drop Rate Increase Modifier
Slayer Processor	・Max Shield ・Toxic Resistance ・Item Acquisition Distance Increase Modifier ・Ecive Display Time

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

For the Reactor, you can use either a Materialized Mixture Reactor or a Materialized Phase Reactor, depending on which ability you want to spam. If you are going to be fighting a lot of mobs, equip the Materialized Phase Reactor since you will primarily be spamming Clean Up, which is a dimension skill.

However, if you plan on taking on a void boss, the Materialized Mixture Reactor would be better since you will be using Bubble Bullet to apply the Laundry debuff from a distance.

The Slayer Set is the ideal External Component to equip for the 26% increase in your Skill Power. However, if you’re experiencing issues with survivability, you can replace the set with DEF Support or HP Support External Components to boost your base Defense and HP, making your defensive modules more effective.

Valby Playstyle Tips

Valby Playstyle Tips
Apply Laundry On the Boss Utilize the Puddle DOT When Clearing Mobs

Apply Laundry On the Boss

When fighting a boss, make sure to apply the Laundry debuff to lower their Electric and Non-Attribute Resistance. This will significantly boost your entire party's damage output and can help you burst down the boss before it becomes frenzied.

All Void Intercept Battle Bosses

Utilize the Puddle DOT When Clearing Mobs

When securing an area, you can create puddles at enemy spawn points to instantly eliminate them. Use this to your advantage to improve your clear speed and overall efficiency during missions.

This build mainly focuses on improving your Skill Cooldown and Skill Power to consistently deal massive damage with your abilities. With this setup, you will be able to spam your skills to apply Laundry. Additionally, Laundry makes the enemy more vulnerable to Non-attribute and Electric attacks, so it is ideal to keep this debuff on enemies as much as possible to maximize the advantage of your weapon's attribute.

Modules Guide: List of Modules

Best Valby Weapon and Modules (Normal)

Weapon		Stat Priority
Thunder Cage		・Electric ATK ・Attribute Status Effect Trigger Rate ・Firearm ATK ・Firearm Critical Hit Rate

Using these modules, you will be able to fully utilize the strengths of your Thunder Cage due to its high Critical Hit Chance, Fire Rate, and its unique Overcharge ability. Further increasing these stats will drastically increase your clear speed, especially if you can apply the Laundry debuff on enemies with your skills, as it lowers their Electricity and Non-attribute Resistance.

Best Weapons Tier List

Best Valby Reactor (Normal)

Reactor	Stat Priority
Materialized Phase Reactor	・Skill Critical Hit Rate ・Skill Critical Hit Damage

Since Clean Up has two charges and a low Cooldown, this will be your main skill to create puddles and apply Laundry. It is best to use a Materialized Phase Reactor to benefit from the Skill Power Boost Ratio bonuses.

Valby Exclusive Equipment

Arche-Hydro Symbiosuit

With her Arche abilities, Valby can turn into water, anytime and anywhere. As such, her unique drawbacks are also like water. Over time, moisture evaporates, and she is unable to maintain her shape. Valby's exclusive suit is an environmental shielding suit that was designed to compensate for this. Not only does it assist in Arche-hydrogen bonding, so she can take on human form, but it also features shape memory technology that enables Valby to assemble, and disassemble, with Arche, providing her with various tactical capabilities.
