Zero Build Guide

Cosmos View Character

Zero is a burst Sub‑DPS who frontloads most of their damage into their Skill and Ultimate. They excel at short, high‑value windows (quick swaps, Cycle triggers) and scale with Awakening effects, making them a strong carry through most content but less optimal as a full‑time endgame main DPS.

Strengths

  • Huge frontloaded burst from Skill + Ultimate; great for quickswap burst rotations
  • Instantly fills their Cycle Energy with their Skill, enabling immediate Esper Cycle triggers
  • Synergizes well with Lakshana/Anima teammates to generate Charge and fast Ultimate energy
  • Lost Radiance 4pc (ignore 25% DEF after Ultimate) multiplies their burst potential

Weaknesses

  • Most damage concentrated in Skill/Ultimate windows — limited sustained damage outside bursts
  • Relies on team swaps and Cycle reactions to fully realize damage potential
  • Best Arc (The Rain That Shook the World) is paid, so optimal setup may require purchases

Best Main Stat: CRIT Rate or Cycle Intensity

  • CRIT Rate is the go‑to main stat for consistent burst damage.
  • Choose Cycle Intensity if your team triggers many Esper Cycles (full quickswap teams) so Zero benefits from cycle scaling.

Best Teams

Esper Zero Sub DPS

Zero functions as a Sub‑DPS burst unit here: use their Skill + Ultimate windows to amplify the Main DPS (Nanally or Mint) and enable strong Cycle reactions with Jiuyuan and a support who provides CC/ATK (Sakiri).

Zero

Zero

Sub-DPS

Primary burst contributor; swap in to use Skill/Ultimate and trigger Cycles.

 Nanally

Nanally

Main DPS

Primary carry in the listed composition; receives Blossom/Charge buffs.

 Jiuyuan

Jiuyuan

Sub-DPS

Synergizes to help trigger Blossom/Blossom‑empowered cycles.

 Sakiri

Sakiri

Support

Provides crowd control and ATK buffs; enables Hexed Esper Cycle.

Start with a Lakshana/Anima teammate (if available) who has full Cycle Energy, swap to Zero to trigger Remora/Bloom immediately.

Use Zero's Skill to instantly fill their Cycle Energy, then Ult if ready for max burst.

Swap back to your Main DPS (Nanally/Mint) to trigger Blossom and run their damage rotation while Zero's effects are active.

Coordinate to trigger Charge (having both Lakshana and Anima reactions) to fuel Ultimates rapidly.

  • This comp easily triggers the Blossom Esper Cycle; Jiuyuan can empower Blossom for extra damage.
  • Sakiri enables Hexed Esper Cycle for additional damage opportunities.

Skill Priority

3

Appraisal (Basic Attack)

Basic Attack is lower priority for a burst Sub‑DPS; level if you plan to run Zero as Main DPS.

3

Rift Blossom (Support Skill)

Nice for bonus damage and utility; level last since primary damage sources are Skill/Ultimate.

4

Appraise and Engrave (Skill)

Level second — Skill fully charges Cycle Energy and is used as often as the Ultimate.

5

Divice by Zero (Ultimate)

Maximize first — most of Zero's damage comes from using the Ultimate frequently.

Awakening Priority

1

Anomalies Record

Top priority — increases CRIT Rate and sets up Higher Ultimate damage; get this first.

2

Undecided Factors

Second priority — improves Ultimate damage further.

3

Deceptive Liberation

Third priority — boosts Skill damage, making Zero's skill bursts more reliable.

4

Finding the Calling

Fourth priority — helps facilitate Ultimate usage and frequency.

5

Theopneustos

Quality‑of‑life: gives some ATK when Zero's Support Skill triggers; low priority.

6

Blooming Gaze

Deals extra damage to low‑level enemies; useful but lowest priority.

How to Play

Use Zero's Skill to instantly fill Cycle Energy and open burst windows with their Ultimate. Swap to a Lakshana or Anima teammate to trigger Esper Cycles (Remora/Blossom), and coordinate reactions to grant Charge for fast Ultimate energy. Lost Radiance + Ultimate → follow up with Redirect Skills for maximum damage.

Rotations

  1. 1 Sample Full Rotation: Jiuyuan Skill → Sakiri Hold Skill → Sakiri Ultimate → Esper Zero Skill → Esper Zero Ultimate → Swap to Nanally (Blossom Trigger) → Nanally Skill → Nanally Ultimate → Spam Normal Attacks → Jiuyuan Ultimate
  2. 2 Standard burst: Swap in → Skill (fills Cycle) → Ultimate → swap out to a Cycle partner to trigger reactions and continue Main DPS rotation.

Tips

  • If you have a Lakshana or Anima with full Cycle Energy, start with them and swap to Zero to immediately trigger Remora or Bloom.
  • Always use Zero's Skill to fill Cycle Energy and then swap to trigger the Cycle reaction for Charge or Blossom.
  • Level Zero to cap — Skill deals an extra instance of damage on enemies lower than their level, so maxing is worth it.
  • Use Lost Radiance's 4pc: cast Ultimate to activate the DEF‑ignore window, then use Redirect Skills while it lasts.
