Who Is Esper Zero and Why Build Him First?

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

Esper Zero ranks solidly in A-tier for overall usability with excellent mob clearing, decent single-target scaling, and low skill floor. Most Neverness to Everness beginners love him because he carries early story content solo, while veterans pair him with supports for Blossom and Remora chains that melt stagger bars. Investing here pays off long-term since he’s free to obtain and easy to raise.

Esper Zero Skills and Playstyle Explained

For a better Neverness to Everness Esper Zero build, you have to carefully go through his skills and get a good idea on it. Zero’s kit is about steady basic attack chains that build Esper Cycle value, followed by a skill that sets up reactions and an ultimate that cashes out big damage.

So, here’s the exact breakdown of these skills:

• Basic Attack – Appraisal (Severance): Up to five consecutive energy-charged sword strikes. These are your bread-and-butter for maintaining field presence and charging the Esper Cycle meter naturally.
• Skill – Appraise and Engrave: Three quick weapon strikes into an aerial leap and charge, then fire an Esper Cannon dealing one instance of Cosmos area damage. It adds an extra Cosmos hit to the first enemy whose level is below Zero’s and this is ideal for overworld mobs and lower-level bosses.
• Ultimate – Divide by Zero: A sweeping blade dance that severs invisible Nexus lines, dealing multiple instances of Cosmos damage across an 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.
• Passives: Appraiser restores HP (50% of base ATK) whenever the active character gains ultimate energy. Anomaly Perception boosts Divide by Zero damage by 25% permanently.

Core Playstyle and Rotation Stay on-field with normals to build meter, then drop Appraise and Engrave to accelerate the cycle and trigger reactions (especially Blossom with Anima teammates). Swap out for supports to cash in Remora marks or Charge energy, then return and ult during stagger for maximum burst. The rotation feels natural: Normal chain → Skill → Support swaps → Ultimate → repeat. It rewards clean timing over perfect execution, making Zero forgiving in chaotic urban fights.

Talent (Skill) Upgrade Priority

You can focus resources efficiently so your 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 main damage spike.
3. Basic Attack last – Only after the core loop is solid, since normals scale naturally with field time.
