Best Weapon for Valby in The First Descendant

Like Bunny, the best weapon for Valby is arguably the Thunder Cage SMG. In addition to being a powerful high fire-rate ultimate weapon, Thunder Cage synergizes well with Valby’s abilities and playstyle. 

Best Bunny build in The First Descendant — mobility, range, and more

For instance, Thunder Cage can emit electric shockwaves, whereas Valby’s abilities can inflict a water status effect on enemies called Laundry. As you can predict, enemies inflicted with Laundry can take additional damage from the electric damage dealt by Thunder Cage.  

Since all of Valby’s abilities can inflict Laundry, you will always deal bonus damage from Thunder Cage.

The best Modules for Valby are the ones that improvise skill usage, boost skill damage, and reduce skill cooldown. Valby is a very mana-heavy Descendant, and it would be quite inconvenient if you can’t activate her abilities in intense situations to deal AOE damage and inflict CC on enemies.

Modules like Enlightenment, Technician, Technique Manual, Skill Extension, Nimble Fingers, and Strong Mentality will improve attributes related to her skills.

The Valby-exclusive Transcendent module, Water Play, is also one of the best choices for the skill module since it can increase the efficiency of the Bubble Bullet skill.  

Shock Punch is a solid choice for the sub-attack module as it can synergize with Valby’s abilities and the choice of weapon and deal additional electric damage to enemies. 

Best Reactors for Valby in The First Descendant

It’s best to equip the Materialized Phase Reactor since it can boost Valby’s Non-Attribute and Dimension skills. You may also want to equip a Tactical Rifle in one of the weapon slots to meet the optimization condition and gain additional skill power.
