Case File #zero
A TierZero Build Guide
Zero frontloads damage into their Ultimate and Skill, offering scaling burst potential through Awakenings. However, this reliance on burst makes them better suited as a Sub-DPS for general play, falling off in endgame content.
Strengths
- High burst damage from Skill and Ultimate
- Scales well with Awakening effects
- Quickly triggers Esper Cycles with Skill
Weaknesses
- Damage is heavily tied to Ultimate and Skill
- Not ideal as a main DPS for endgame content
- Limited sustained damage output
Best Arcs

Hypervortex: Deals 30% increased Cosmos DMG with Redirect Skill and Ultimate. Increases Cycle Intensity by 36 for 15s after casting Redirect Skill. Resets duration when triggered again.

Eclipse: Increases ATK by 30%. Unlocks Arc: Eclipse. Creates a 40s Eclipse where each enemy defeated restores 6 Ultimate Energy, up to 5 times (cooldown 300s).

Picture Frame: Increases ATK by 20% when HP > 50%; increases DEF by 20% when HP < 50%.
Best Cartridge
Epic (2): Cosmos DMG +10%. Legendary (4): Ignores 25% enemy DEF for 20s after Ultimate. Does not stack.
Best Main Stat: CRIT Rate or Cycle Intensity
- CRIT Rate improves burst consistency; Cycle Intensity is better in quickswap teams with frequent Esper Cycles.

Best Teams
Zero acts as a secondary damage dealer alongside Jiuyuan, supporting Nanally as the main DPS. This team triggers the Blossom Esper Cycle, which Jiuyuan can empower.

Zero
Sub-DPS
Burst damage and Cycle Energy charging.

Nanally
Main DPS (Flex)
Primary damage dealer; can be replaced by Mint.

Jiuyuan
Sub-DPS
Empowers Blossom cycle and provides damage.

Sakiri
Support (Flex)
CC and ATK buffs; can be replaced by Adler for more defense.
Alternatives
Open with Jiuyuan's Skill, then Sakiri's Hold Skill and Ultimate.
Swap to Zero and use Skill → Ultimate for burst.
Swap to Nanally to trigger Blossom, then use her Skill, Ultimate, and normal attacks.
Use Jiuyuan's Ultimate when available.
- Rotation remains similar with Mint; spam Mint's Skill due to low cooldown.
- Team can also trigger Hexed cycle with Sakiri or charge cycle with Lakshana/Anima combos.
Skill Priority
Appraisal (Basic Attack)
Lower priority for burst DPS; level if using Zero as main DPS.
Rift Blossom (Support Skill)
Level last; provides bonus damage but not core to Zero's output.
Appraise and Engrave (Skill)
Level next; used as often as Ultimate for damage and Cycle Energy.
Divice by Zero (Ultimate)
Max first; most of Zero's damage comes from frequent Ultimate usage.
