The First Descendant INES Best Build For Void Erosion Purge

 

INES Void Erosion Purge Mastery Guide

INES is a high‑impact electric Descendant built around area control and burst damage, which makes her uniquely suited to the Void Erosion Purge challenge where waves, environmental hazards, and escalating enemy density punish slow or single‑target approaches. Her kit favors chaining crowd control into concentrated damage windows, letting you collapse packs and pressure bosses with minimal downtime. This guide turns that raw potential into a repeatable, stage‑clearing machine by aligning weapon choices, module synergies, arche tuning, and component priorities to the Purge’s pacing and threats. Void Erosion Purge is endgame content that rewards optimized builds and careful resource management; the right INES setup converts her AoE strengths into consistent stage progression and survivability.

Core philosophy and playstyle

The core philosophy for this INES build is control then detonate: use crowd control and positioning to bunch enemies, then detonate with high‑value burst windows that scale with your modules and components. Prioritize sustained AoE damage, MP efficiency, and mobility so you can reposition between eruptions and avoid Void hazards. You will alternate between a suppression rhythm—disrupting enemy movement and reducing incoming damage—and a burst rhythm—unleashing charged or mod‑amplified skills to clear rooms and pressure bosses. This hybrid rhythm keeps MP usage manageable while maximizing damage per engagement.

Weapons and why they matter

Choose weapons that complement INES’s AoE and burst profile. The ideal primary weapon is one that offers wide coverage, quick follow‑up shots, and strong synergy with electric damage multipliers. Your secondary should either extend crowd control or provide a high single‑target punch for elite enemies and bosses. Weapon selection should favor:

• Wide AoE primary with fast projectile spread and high base crit.

• High burst secondary for boss windows and elite melts.

• Utility weapon options that add CC or debuffs if your primary/secondary lack them.

Weapon mods and components that increase critical damage, electric damage, and area radius are top priority. Weapons that scale well with arche tuning and components will outpace raw stat increases, so test combinations in lower Purge stages before committing to a final loadout.

Modules and arche tuning

Modules are the backbone of any competitive INES build. Focus on modules that:

• Amplify electric damage and chain effects.

• Reduce MP cost or increase MP regeneration to sustain repeated detonations.

• Increase AoE radius or add secondary explosions on kill.

Arche tuning should be used to emphasize the attributes that feed your modules: prioritize skill damage, MP efficiency, and critical chance. If you have access to arche tuning that boosts elemental chain multipliers or increases the duration of crowd control, slot those early. The right tuning turns modest module bonuses into exponential damage gains during Purge windows.

Core components and stat priorities

Components are the fine‑tuning layer that turns a good build into a great one. Prioritize the following stats in order:

1. Electric damage — primary scaling stat for INES’s kit.

2. Skill damage — multiplies your burst windows.

3. Critical damage and chance — increases peak output.

4. MP efficiency or MP regen — keeps your rotation sustainable.

5. Survivability stats (HP, damage reduction) — only after damage thresholds are met.

Slot components that grant on‑kill effects or chain explosions; these synergize with INES’s tendency to clear packs and trigger follow‑up damage. When choosing between a raw damage component and one that grants utility (like brief invulnerability or a speed boost), prefer the utility if it meaningfully improves your ability to control space in Purge arenas.

Skill rotation and combat flow

Mastering the rotation is more important than raw numbers. The recommended combat flow is:

• Engage and cluster: Use mobility and CC to gather enemies into a tight group.

• Apply sustained pressure: Lay down persistent electric effects that tick and weaken the pack.

• Detonate: Trigger your high‑damage skill or weapon combo when enemies are clustered.

• Reposition: Use mobility to avoid Void hazards and prepare for the next wave.

Timing is everything: detonating too early wastes potential, detonating too late risks being overwhelmed. Practice the rhythm in lower Purge stages to internalize the timing windows for your chosen modules and weapons.

Mobility and positioning

Void Erosion Purge maps often include environmental hazards and shifting enemy spawns. Mobility is not optional. Equip movement modules or components that grant short bursts of invulnerability or repositioning. Use cover intelligently: INES benefits from line‑of‑sight breaks that let her set up AoE detonations without taking unnecessary damage. When possible, funnel enemies into choke points where your AoE radius and chain effects can maximize value.

Team synergy and role in squads

INES excels as a primary pack clearer and secondary boss damage dealer. In a team, your role is to:

• Control enemy flow with AoE and CC.

• Create burst windows for teammates by grouping enemies.

• Provide consistent pressure so teammates can focus single targets.

Coordinate with teammates who can lock down elites or provide sustained single‑target damage during your detonation windows. Pairing INES with a tanky Descendant that can hold aggro or a support that boosts MP regen will dramatically increase Purge success rates.

Survivability tactics

Survivability in Void Erosion Purge is a mix of build choices and play decisions. Use components that grant on‑hit healing or damage reduction when surrounded. Keep an eye on MP and cooldowns; running out of MP mid‑engagement is often fatal. When overwhelmed, prioritize escape and regroup over forcing a risky detonation. Defensive modules that reduce incoming damage or grant brief invulnerability are often more valuable than marginal damage increases in higher Purge stages.

Stage progression and pacing

Void Erosion Purge escalates in difficulty as you progress through stages. Early stages are opportunities to farm components and test synergies; later stages demand tighter execution and optimized gear. Pace your runs: don’t burn all your high‑value consumables on early stages unless you’re confident in a full clear. Learn enemy spawn patterns and hazard timings so you can plan detonations around safe windows.

Consumables and temporary boosts

Bring consumables that restore MP, boost electric damage, or temporarily increase critical chance. Use them strategically—save the most potent consumables for boss waves or when you hit a stretch of stages with dense spawns. Consumables that grant temporary mobility or damage reduction can be clutch when a Purge arena becomes chaotic.

Example loadout (detailed)

This example is a tested baseline that you can tweak based on available gear and playstyle:

• Primary weapon: Wide AoE rifle with electric damage bonus and crit chance.

• Secondary weapon: High single‑target launcher or shotgun with burst mods.

• Modules: Electric chain amplifier; MP regen module; AoE radius booster; on‑kill explosion trigger.

• Arche tuning: Skill damage + electric multiplier focus.

• Core components: Electric damage + skill damage; critical damage; MP efficiency; on‑kill chain explosion.

This configuration emphasizes sustained AoE pressure with reliable burst windows and manageable MP consumption. Swap the secondary for a utility weapon if your team lacks CC or debuffs.

Fine tuning and testing

No build is final. Run repeated Purge attempts to test:

• MP sustainability: Are you running dry before the boss wave?

• Damage windows: Are your detonations clearing packs reliably?

• Survivability: Do you survive elite ambushes and environmental hazards?

Adjust modules and components iteratively. Small changes to arche tuning or a single component swap can shift the build’s balance between damage and survivability.

Advanced tips and tricks

• Chain detonation: Time your detonations so that on‑kill explosions trigger other on‑kill effects, creating cascading damage that clears rooms faster.

• MP pooling: Hold MP for boss windows rather than spending it on every minor pack.

• Environmental leverage: Use map hazards to funnel enemies into your AoE rather than fighting in open space.

• Cooldown juggling: Stagger your high‑impact skills so you always have a detonation ready when enemies cluster.

• Adaptive loadouts: Keep a secondary set of modules for boss‑heavy stages versus mob‑heavy stages.

Troubleshooting common failure modes

If you’re failing Purge runs, diagnose these common issues:

• MP mismanagement: You’re detonating too often or not using MP regen modules.

• Poor positioning: You’re fighting in open areas where enemies can flank and overwhelm you.

• Wrong weapon pairing: Your secondary doesn’t cover single‑target needs, leaving elites alive.

• Lack of team coordination: In squads, uncoordinated detonations waste potential.

Address each issue methodically: adjust modules, swap a weapon, or practice positioning in lower stages.

Build variants and situational swaps

• Speedclear variant: Maximize AoE radius and cooldown reduction; sacrifice some survivability.

• Survivability variant: Add damage reduction components and on‑hit healing; accept slower clears.

• Boss‑focused variant: Swap to a secondary with extreme single‑target damage and tune arche for crit.

Switch variants between runs depending on the Purge stage composition and your team’s makeup.

Progression roadmap

1. Early Purge runs: Farm components and test weapon synergies.

2. Mid Purge runs: Lock in arche tuning and refine modules.

3. Late Purge runs: Optimize components for peak electric and skill damage; coordinate consumable use.

4. Endgame mastery: Master positioning, timing, and team synergy to push the highest stages.

Minimal bullet summary of must‑do items

• Prioritize electric damage, skill damage, and MP efficiency.

• Use a wide AoE primary and a high burst secondary.

• Slot modules that amplify chains, reduce MP cost, and increase AoE.

• Practice the control then detonate rhythm.

• Coordinate with teammates to maximize detonation windows.

FAQ

What makes INES better than other Descendants for Void Erosion Purge? INES’s kit centers on wide‑area electric effects and efficient MP usage, letting her clear dense packs and create burst windows that scale well with modules and components. This makes her particularly effective at the Purge’s mob‑heavy stages and flexible enough to contribute to boss damage.

Which weapon types should I avoid for this build? Avoid slow single‑target weapons as your primary; they undermine INES’s AoE strengths. If you must use a single‑target primary, ensure your secondary or modules compensate with AoE or chain effects.

How do I manage MP during long Purge runs? Invest in MP regen modules and MP efficiency components, and practice MP pooling—save MP for boss windows rather than spending it on every minor pack. Consumables that restore MP are also essential for extended runs.

Is this build viable for solo play? Yes. With the survivability variant and careful positioning, INES can solo many Purge stages. However, team play amplifies her strengths, especially when teammates lock down elites or provide MP support.

What are the best modules to farm first? Farm modules that increase electric damage, reduce MP cost, and add on‑kill explosions. These provide the most immediate and compounding benefits to INES’s core playstyle.
