Best Esper Zero Build Guide: Skill, Arc and Teams | NTE

With Neverness to Everness currently listing its global launch for April 29, 2026, Zero is shaping up to be one of the easier Cosmos characters to build around early on. He has a clean on-field kit, smooth rotation flow, and a very straightforward job in team play. This guide covers the parts that actually matter for getting him online fast: upgrade priority, Arc choice, Awaken picks, and the teams that let him perform at his best.

 

Overview

Rarity:S-Rank   Weapon: Sword   Element: Cosmos

Zero is a Cosmos on-field driver. His primary function is to stay on field, maintain team tempo, and enable Cosmos-based Esper Cycle reactions while providing consistent damage during the rotation. Rather than acting as a pure support or a burst-only swap unit, Zero fills the role of a stable frontline damage dealer who helps keep the team’s reaction flow active.

 

Core mechanics

Zero’s kit is built around steady field time and clean reaction uptime. His Basic Attack gives him a simple five-hit string for continuous on-field presence, while Appraise and Engrave is the key button in his rotation: it deals AoE Cosmos damage and adds an extra Cosmos hit to the first target hit under its level condition.

In NTE’s combat system, Esper Cycle is charged through attacking, using a skill, or parrying, MC’s skill can instantly fill the meter through its high Cycle Rate interaction. That is what makes Zero function best as a driver: he is there to keep the cycle active, trigger Cosmos-side reactions consistently, and turn that tempo into real damage instead of playing like a short-field burst unit.

Once the rotation is established, Divide by Zero becomes his main damage conversion tool, and Anomaly Perception further increases its damage by 25%, reinforcing his role as a frontline unit that sustains team flow and cashes out with reliable Ultimate damage.

 

Skill Kit

Basic Attack	Appraisal	Severance: Zero wields his weapon to channel energy, performing up to 5 consecutive attacks.
Skill	Appraisal and Engrave	Weakness exposed! Zero performs 3 consecutive weapon strikes, leaps into the air to charge, and fires an Esper Cannon that deals 1 instance of Cosmos DMG to an area. Additionally deals 1 instance of Cosmos DMG equal to 200% ATK to the first enemy hit whose level does not exceed Zero's own level.
Ult	Divide by Zero	Deals multiple instances of Cosmos DMG.
QTE	Rift Blossom	Slashes through space and detonates a rift, dealing 2 instances of Cosmos DMG to an area.

 

Skill Upgrade Priority

Skill > Ultimate > Basic Attack

For Zero, this priority is mainly about resource efficiency, not raw tooltip reading.

His Skill is the first upgrade because it is the part of his kit that helps start his rotation and push Esper Cycle tempo the fastest, which matters a lot for a Cosmos on-field driver.

His Ultimate comes next because that is where Zero converts his field time and reaction setup into real personal damage, and his passive further reinforces its value.

Basic Attack is still worth raising later for smoother on-field output, but it is not the first place you want to spend limited materials.

In short: level Skill first to improve how quickly Zero gets the team moving, then Ultimate to strengthen his damage payoff, and leave Basic Attack for after his core loop is already online.

 

Weapon Recommendation

Contemplative Cat

• For every 100,000 Fons the wearer holds, ATK +5.00/6.25/7.25/8.75/10.00%. Stacking up to 10 times.

Contemplative Cat is the cleanest premium Arc for Zero out of the options shown here. Its effect is simple but extremely reliable: it grants ATK based on how many Fons the wearer holds, up to 10 stacks, which means Zero gets a broad damage boost that applies to his full kit instead of only one niche trigger window. That fits Zero well, since his value comes from steady on-field pressure, Cosmos damage, and an Ultimate that already has built-in bonus scaling from his passive.

 

Ready-Ready

• Wearer ATK +16/20/24/28/32%. Casting a Skill or Ultimate increases Basic Attack damage by 16.00% for 15s (stacks 2 times). Gain Talismans on Skill/Ultimate use; gain both within 15s to trigger Arc: Commander Tiger Talisman, which increases DMG to Bosses by 10.0/12.5/15.0/17.5/20.0% for 10s.

Ready-Ready is the best A-rank Arc for Zero because it supports the exact loop Zero already wants to play. The flat ATK increase is a universal damage boost, while the follow-up Basic Attack DMG bonus after using Skill or Ultimate fits naturally into Zero’s rotation, since Zero wants to use both to keep pressure up and stay active on field. The extra boss damage trigger is also a real upside, giving Zero better value in tougher single-target fights instead of only padding easy mob stages. Overall, Ready-Ready is the most complete and reliable budget weapon for Zero because it strengthens Zero’s full damage pattern rather than a narrow gimmick.

 

Console Recommendation

For Console, I’d keep Zero very standard: lean into ATK%, Cosmos DMG, Crit Rate, and Crit DMG first, then treat Essentia as a side stat rather than the main event unless later testing proves a specific reaction build is overtuned.

Community beta documentation for the Tetris-piece system shows those stats in the main/substat pools, and it also notes that Zero gets +10% ATK for every Type III Tetris Piece equipped. That makes Type III-heavy layouts especially attractive on him when the board shape allows it.

The other nice part is that substats are visible before upgrading, so Zero is one of those characters where you can be picky and just fish for clean DPS pieces instead of coping your way through cursed rolls.

 

Awaken Recommendation

Because Zero’s Awaken tree is flex-pick, for most players, 2 extra copies is the best stopping point. Take Finding the Calling first, since gaining 8 Ultimate Energy after casting Appraise and Engrave is the cleanest all-purpose upgrade in Zero’s tree. It improves his rotation every time he does his normal job. For the second pick, Anomalies Record is the safest default because +50% Crit Chance on Divide by Zero makes his main damage cash-out far more reliable.

If you plan to go to 3 copies, unlock Undecided Factors next. It directly boosts Divide by Zero by up to 25%, which gives Zero a stronger endgame payoff than investing into his Skill-side extra-hit line too early. If your build already has enough Crit Rate, you can even swap the second and third priorities and take Undecided Factors before Anomalies Record for a little more ceiling.

At 4–5 copies, I would generally prioritize Theopneustos next, then finish the Skill branch. Theopneustos gives Zero 10% ATK for 20s when he triggers Support Skill, which is broader and less conditional than his extra-hit awakenings. After that, Deceptive Liberation is usually the better Skill-side pick because it raises Appraise and Engrave’s extra damage ratio to 300% ATK.

Blooming Gaze is the lowest priority for most players: the extra hit and 75% DEF ignore can look strong, but it still depends on the lower-level target condition, so it is much better in overworld, farming, or easier mob content than in harder endgame fights.

 

Team Recommendations

Zero

Nanally

Hathor

Fadia

The strongest all-around full team I’d recommend right now is Zero + Nanally + Hathor + Fadia. Nanally upgrades the Blossom side by spawning 1 additional Lebenstamm, and while she is in Ichi-daime’s Authority, she can also follow up on teammates’ Esper Cycle damage. Hathor upgrades the Remora side through her Remora Enhancement, and her Ultimate gives her a stronger post-cast state with upgraded Skill and movement. Fadia completes the team by adding real stability: her Ultimate includes healing, and her passive gives the whole team +10% max HP. In practice, this is the cleanest “complete” Zero team because every slot has a clear job — Zero drives, Nanally boosts Blossom, Hathor strengthens Remora, and Fadia keeps the run from falling apart.

 

Zero

Mint

Skia

Fadia

If you want a more practical and easier-to-pilot version, go with Zero + Mint + Skia + Fadia. Mint’s Blossom Enhancement makes each Lebenblume split into two before exploding, which gives the team a very smooth and automatic Blossom side. Skia brings Remora Enhancement, and after using The Pack, his attacks gain extra value while also applying control effects, which makes the team feel safer and more comfortable in actual gameplay. Fadia again is the glue here: she adds healing, HP padding, and defensive breathing room so Zero can stay on field and keep the Charge loop going instead of constantly getting forced out. This team is a little less flashy than the Nanally-Hathor version, but it is usually the easier one to recommend for consistent play.

 

Conclusion

Zero is the kind of character who rewards clean planning more than flashy theory. Once you set up his rotation properly and give him a team that actually feeds his reaction loop, he feels smooth, reliable, and way more useful than a lot of players expect at first glance. Whether you want the stronger premium setup or a more practical team that is easier to pilot, the goal is the same: let Zero stay comfortable on field and keep the engine running.

And if you end up needing a few extra pulls later to finish his setup, keeping an eye on LDShop for NTE top-up deals is an easy way to save big while you build toward the version you actually want.
