Who Is Esper Zero and Why Build Him First?

Esper Zero stands out as the protagonist you can freely gender-swap between male and female versions, making him (or her) instantly relatable. His Cosmos element shines in reaction-heavy teams, and his sword-based playstyle rewards consistent field time rather than complicated character swaps.

Zero ranks solidly in A-tier for overall usability: he offers excellent mob clearing, decent single-target scaling, and an extremely low skill floor. Most Neverness to Everness beginners love him because he can carry early story content solo. At the same time, veterans pair him with supports to trigger Blossom and Remora chains that melt stagger bars without breaking a sweat. Investing in Zero pays off long-term since he is free to obtain and exceptionally easy to raise.

Esper Zero Skills and Playstyle Explained

To get the most out of your Esper Zero build, you first need a clear picture of how his kit works. Zero revolves around steady basic attack chains that build Esper Cycle value, a skill that sets up reactions, and an ultimate that cashes out massive damage.

Here’s the exact skill breakdown:

• Basic Attack – Appraisal (Severance): Up to five consecutive energy-charged sword strikes. This is your bread and butter for maintaining field presence and charging the Esper Cycle meter naturally.
• Skill – Appraise and Engrave: Three quick weapon strikes transition into an aerial leap and charge, then fire an Esper Cannon that deals one instance of AoE Cosmos damage. It also deals an extra Cosmos hit to the first enemy whose level is below Zero’s — making it ideal for overworld mobs and lower-level bosses.
• Ultimate – Divide by Zero: A sweeping blade dance that severs invisible Nexus lines, dishing out multiple instances of Cosmos damage across a wide area. This is your big payoff move during stagger windows.
• Support Skill / QTE – Rift Blossom: When swapped in, Zero slashes space open and detonates a rift for two instances of AoE Cosmos damage — great for quick off-field contribution.
• Passive – Appraiser: Restores HP (50% of base ATK) whenever the active character gains ultimate energy.
• Passive – Anomaly Perception: Permanently increases Divide by Zero’s damage by 25%.

Core Playstyle and Rotation:
Stay on-field with normal attacks to build meter, then use Appraise and Engrave to accelerate the cycle and trigger reactions — especially Blossom with Anima teammates. Swap out for your supports to cash in Remora marks or charge energy, then return and unleash Divide by Zero during stagger windows for maximum burst. The rotation feels completely natural: Normal chain → Skill → Support swaps → Ultimate → repeat. It rewards clean timing rather than flawless execution, making Zero forgiving even in chaotic urban fights.

Talent (Skill) Upgrade Priority

Focus your resources efficiently so your core rotation comes online fast:

1. Skill (Appraise and Engrave) first – Improves cycle speed and sets up reactions immediately.
2. Ultimate (Divide by Zero) second – Boosts your primary damage spike.
3. Basic Attack last – Only after the core loop is solid, since normal attacks scale naturally with field time.

Best Weapons for Esper Zero

Your perfect Esper Zero build also depends on equipping the right weapon. Zero’s signature options emphasize raw ATK and boss uptime:

• Hethereau’s Keeper (Signature): The best-in-slot choice. It grants a substantial ATK increase plus direct boss damage amplification — perfect for Zero’s multi-hit ultimate and prolonged field time in single-target encounters.
• Day Off (F2P-Friendly Alternative): Delivers a massive ATK boost that benefits every part of the kit. The kill-based Field Essence refund truly shines in overworld farming and multi-wave events thanks to Zero’s excellent AoE coverage.

To quickly acquire and refine premium weapons like Hethereau’s Keeper without missing limited banners, you can top up securely via Enjoygm. It keeps your account safe while letting you test the weapon’s full potential in boss runs the same day.

Artifact System and Stat Priorities

NTE uses a unique Tetris-piece artifact board, where each Type III piece provides +10% ATK when equipped. Prioritize filling your board with as many Type III pieces as the shape allows.

Main stat priority (in order):

1. ATK% (or Cosmos DMG Bonus on the appropriate slot)
2. Crit Rate
3. Crit DMG

Sub-stat priorities: ATK%, Crit Rate/DMG, then Essentia (for reaction uptime if you are running heavy Blossom teams). Avoid DEF or HP unless you’re purely F2P and require some extra survivability.

Awaken (Constellation) Picks and Priority
Awakens are Zero’s duplicate system. Grab them in this order for the most impactful power spikes:

1. Finding the Calling – +8 Ultimate Energy after using Appraise and Engrave for much smoother rotations.
2. Anomalies Record – +50% Crit Rate on Divide by Zero (consider prioritizing Undecided Factors instead when you have 3 or more copies for even more ultimate damage).
3. Undecided Factors (at 3 copies) – Up to +25% Divide by Zero damage.
4. Theopneustos – Grants +10% team ATK for 20 seconds when a support skill is triggered.
5. Deceptive Liberation – Significantly boosts the extra damage ratio of Appraise and Engrave.
   Lowest priority: Blooming Gaze (conditional extra hit and DEF ignore — more situational and mainly for mobs).

Best Team Compositions for Esper Zero

The strongest Esper Zero teams all revolve around using him as an on-field Cosmos driver. Here are our top recommended lineups:

Build around Cosmos-Anima for Blossom spawns, or Lakshana-Cosmos for Remora slows that let you stay on-field longer. The fourth slot should always cover healing or extra reaction uptime.

Ascension, Leveling, and Materials for Esper Zero
Raise Zero to level 80+ as soon as possible — his scaling is front-loaded and you’ll feel the difference instantly.

Priority checklist:

• Keep character level and weapon matched to your world rank.
• Use standard Cosmos ascension materials (farmable in Hethro anomalies).
• Give Bond gifts to unlock life skills for extra Affinity gains (which helps with future story rewards).

Daily routine: Clear daily anomalies for materials, use Zero actively in exploration for his level-advantage cannon bonus, and farm bosses once you hit the recommended team level.

Pro Tips for Mastering Zero

• Exploit the level-check extra damage on Appraise and Engrave against lower-world mobs for effortless clears.
• Parry to instantly fill the Esper Cycle meter and force immediate reaction windows.
• Time Divide by Zero inside stagger windows to massively deplete stagger bars.
• In the open world, keep Zero on-field — he clears packs faster than most supports.
• Keep an eye on Cosmos reactions: Blossom provides free autonomous damage, and Remora slows targets for safer, more extended combos.

Conclusion

That wraps up the best Esper Zero build guide for Neverness to Everness. Follow this build and Zero will carry you from launch day all the way through endgame anomalies with zero frustration. He’s the protagonist for a reason — invest smart, react clean, and the city of Hethro becomes your playground.
