Updated Valby Build Guide - How to Snapshot - Insanely Strong! - Onslaught | The First Descendant

Storyline / Context

• The clip is set around The First Descendant gameplay, framed by a bounty/operation sequence:
  • The squad locates residual/void energy
  • Tracks a target via scan/data analysis
  • Contains the area
  • Neutralizes the target
• Subtitles then shift fully into a Valby (Vali/Valpie) build guide focus—so the “story” becomes less about narrative plot and more about how to play Valby effectively in Onslaught / Endgame scenarios.

Gameplay Highlights (Valby Build Guide)

Key Theme: Valby’s Power From 3rd Ability Snapshotting

• The core mechanic is that Valby’s 3rd ability (damage via “laundry”/water gun behavior, depending on module/build naming) will snapshot buffs before or at activation.
• After snapshotting, buff duration may expire, but the ability’s damage/effects still keep the prepared stats, as long as you don’t re-activate/reset the 3rd ability.
• Emphasis from the creator:
  • Weapon damage doesn’t matter much in hard content.
  • Many later buffs applied after the 3rd activation are mostly wasted, because damage is already “locked in.”

Video Goals & Build Philosophy

• Three build types are presented:
  • Supply Moisture (crit + non-crit variations)
  • Spiral Title Wave (skill crit build)
  • Another module-based approach referenced as Water Play / Infiltration / Arc-related setups (varies by build)
• General stat priority:
  • Favor skill damage / skill power scaling over weapon investment.
  • Balance Mana / Max Mana multipliers depending on whether a module preserves or removes mana scaling.

Strategies & Key Tips (What to Do / Avoid)

1) Supply Moisture Build (Most Complicated)

Purpose

• Swap passive behavior using a module that provides:
  • Weapon-related buffs (the creator notes they don’t meaningfully translate into weapon damage)
  • Ammo recovery while standing on water
  • Core damage driven by the 3rd ability

Targeting / Interaction Details

Valby’s 3rd ability behavior (as described):

• Applies AOE with a very short damage interval (0.1s stated) when firing hits connect
• Auto-reloads when used
• Triggers on main bullets, not various weapon-side ability effects (examples are listed in the subtitles)

Snapshot Rules: What to Prep

• Buffs must be prepared before activating the 3rd ability because they snapshot.
• Buff categories mentioned as snapshot-dependent:
  • Critical chance
  • Onslaught-mode buffs, unless you keep re-buffing
  • Critical chance added after activation becomes nearly useless

Crit Build vs Non-Crit Build Selection

• The creator recommends the crit build when enemy crit resistance is lower than ~35%.
  • (Bosses often have crit resistance, so checking values is stressed.)
• Crit build performs best with a strong critical hit rate “ancestor” module setup:
  • Referenced as a “3 positives + 1 negative” style tradeoff.
• The creator highlights:
  • You may need good crit rate for consistent execution
  • Damage is described as extremely high, but execution is harder

Survivability Trade

• If Onslaught feels unsafe:
  • Swap/adjust modules—specifically swapping Skill Expansion for an HP module is mentioned in the subtitles.

2) Pre-Fight Rotation Example (for Buff Snapshotting)

A step-like rotation designed to ensure buffs are active when your 3rd ability sequence begins:

1. Equip Wave of Light
   • Shoot 1–2 bullets
   • Reload when the enemy spawns
2. Trigger arc reload / hyperfocus
   • Shoot the ability and hit the enemy to proc arc reload and hyperfocus
3. Switch to Peacemaker
   • Cast 1st ability → 2nd ability → 3rd ability
   • This activates Enlightened Mage and Peacemaker buffs
4. Switch to Hammer and Anvil
   • Use it as the main weapon to snapshot those buffs
   • Then do damage as long as the 3rd ability doesn’t reset

Fallback if Rotation Is Too Complex

• Replace Hyperfocus with HP or other modules as needed.
• Replace Wave of Light with Python for bosses:
  • Python is described as applying non-attribute resistance shred on weak point hits.

3) Second Variation: Non-Crit / “Can’t Crit Well” Approach

• If you don’t have a good critical-hit-rate ancestor module:
  • Subtitles claim non-crit may be better on paper for enemies around 40% crit resistance
  • But in practice it may take longer because you may “fish for crits.”
• “Widespread execution” is described as difficult to snapshot because it only happens when 3rd ability damage triggers.
  • Alternatives like HP or other modules may replace it.

4) Spiral Title Wave Build (Skill Crit Build)

Core Mechanic

• The passive is modified to grant flat 20% critical hit rate.
• The creator claims this build performs best even with roughly ~84% crit chance.

Scaling / Stat Trade-Offs

• Avoid stacking too much non-attribute skill power ratio due to diminishing returns.
• Preferred scaling focuses on:
  • Critical damage
  • Fusion skill power damage
• Focus modules are still needed because the build has low skill modifier.
• Arc-chain catalyst interaction:
  • Non-attribute resistance reduction (stated as reaching 20%) requires focus setup.

Mana Note

• For Spiral Title Wave:
  • Mana scaling is removed, so you don’t need to hit max-mana caps.
  • It still uses Infiltration Mechanism, since you still have ~360 max mana and an amplifier around 400%.

Arcade Tuning / Cooldown Focus

• Aims for strong cooldown reduction:
  • The subtitles mention 87% cooldown reduction total for the Spiral plan.
• Also notes you can build range/HP depending on efficiency needs.

5) Water Play / Quality-of-Life Modules

• The creator reiterates Water Play is valuable because it allows:
  • Pre-casting the first ability
  • Improving fight setup and scaling into mana
• Water Play is conceptually compared to earlier water-based playstyles (stacking puddles before enemies spawn).

Bugs / Quality-of-Life Feedback (Mentioned)

• The creator reports several issues/requests:
  • Want Valby to be able to use the grappling hook while her 3rd ability is active
  • Wants Valby not to cancel 3rd ability when using the 4th ability
  • Mentions bugs involving the Singing Water module
• Despite that, they conclude Valby feels better than before, including:
  • Slight damage buffs
  • Some ability scaling tied to max mana
