Sereniel Best Build Guide: Skills, Cards and Teams - Chaos Zero Nightmare

Merry Christmas, Commanders! With the launch of the new season in Chaos Zero Nightmare, the game welcomes its very first limited unit—Sereniel. As an Instinct-attribute Hunter, Sereniel specializes in rapidly shredding enemy Tenacity through her unique Afterglow mechanic, enabling frequent Ravage states and explosive burst damage.

This guide walks you through Sereniel’s core mechanics, optimal card builds, potential priorities, partner and memory setups, team compositions, and pull recommendations, helping you quickly understand why she stands out as one of the strongest single-target DPS units in the current meta.

 

 

If you’re managing multiple accounts or running different team setups in parallel, OSLink’s multi-instance automation is a powerful time-saver. By recording a single script, you can auto-run farming, dailies, and weekly content across multiple emulators at once—stable, uninterrupted, and completely hands-free. It’s one of the most efficient ways to scale account progression without extra effort.

 

 

I. Sereniel Overview

Attribute & Role

Instinct — Single-Target Break DPS

Sereniel excels at Tenacity Damage, allowing her to break enemies quickly and convert those breaks into massive burst windows. Her damage output is highly consistent and only minimally affected by enemy attributes, giving her excellent universal performance across content.

 

Core Mechanic

Sereniel’s attack cards apply Afterglow, dealing additional Tenacity Damage. When enemies enter Ravage state, Sereniel gains significant damage bonuses.

 After successfully breaking an enemy, she can retrieve attack cards, enabling rapid cycling and sustained pressure.Combined with the Judgment’s Flames memory set, her damage loop becomes extremely fluid, powerful, and self-sustaining.

 

II.Sereniel Card Builds

Basic Cards

 

Keep

• Pulse Fire

 After unlocking the relevant Potential, Pulse Fire has a 50% chance to generate Homing Laser L, making it core to Sereniel’s engine.

 

Remove

• Magnetic Field

 Provides minimal value and disrupts deck flow. Recommended to delete.

 

Epiphany Cards & Priority

Homing Laser

 

Core zero-cost DPS card. Returns to hand upon Ravage, enabling high-frequency attacks.

Epiphany Priority:

2 > 3 > 1 = 4 > 5

Homing Laser(2): Increases Afterglow stacks by 3 — best overall coverage.

Homing Laser(3): Generates 2 Homing Laser L, but removes Ravage retrieval — niche.

Homing Laser(1)/(4): Lower Afterglow coverage.

Homing Laser(5): Graveyard-dependent draw, inconsistent.

 

Plasma Missile

 

1-cost opener card for Tenacity shredding.

Epiphany Priority:

3 > 1 > 4 > 2 > 5

Epiphany Priority(3): Applies Instinct weakness and boosts Homing Laser damage.

Epiphany Priority(1): Strong raw damage and Tenacity reduction.

Others are situational or awkward to use.

 

Shining Core

 

Primary source of Homing Laser L, which also applies Exhaust.

Epiphany Priority:

3 > 1 > 2 > 5 > 4

Shining Core(3): Enhanced version, generates 2 Homing Laser L on Ravage.

Shining Core(1): Straightforward 3-card generation.

Shining Core(2): Adds usage count but risks hand clogging.

 

Cobalt Light

 

High-cost multi-hit attack.

Epiphany Priority:

1 > 2 > 3 > 5 > 4

Cobalt Light(1): Cost reduction on Ravage — excellent flexibility.

Cobalt Light(2): Adds Retain, useful for planned burst turns.

Cobalt Light(3)/(4)/(5): Remove Tenacity Damage — not recommended.

 

III. Potential Priority

• 03-1 — Enables Pulse Fire to generate Homing Laser L
• 07 — Boosts Homing Laser damage
• Damage Potentials: 04 → 05 → 06
• 02, 05-1

 

Neutral card Potentials can be skipped if resources are limited.

 

 

IV. Partner Recommendations

Exclusive Partner

Peko

 

 Increases damage to Ravaged enemies and permanently boosts attack card damage when retrieving cards from the graveyard—perfect synergy.

 

Alternatives

• Kiara: Damage scaling based on graveyard size

 

 

• Carroty: Boosts attack power for generated cards

 

 

 

V. Memory Fragment Setup

Set Recommendation

• 4× Judgment’s Flames
• 2× Executioner’s Tool

 

Judgment’s Flames massively boosts Instinct damage against Ravaged enemies, effectively tailor-made for Sereniel. Executioner’s Tool adds critical damage.

 

Stat Priority

Main Stats

 

• Slot 4: Crit Rate
• Slot 5: Instinct DMG or ATK
• Slot 6: ATK

 

Substats

 Crit Rate = Crit DMG > ATK > Self-Awareness Regen

 

VI. Team Compositions

1. Dual DPS Team

Sereniel + Chizuru + Rei

 

• Sereniel rapidly generates 0-cost attacks to stack Chizuru.
• Chizuru reduces AP costs with Bound at Dusk, enabling Sereniel’s high-cost cards.
• Rei boosts 0-cost damage and auto-triggers attack cards without AP.

 

Deck Setup Examples

 

2. Single DPS Team

Sereniel + Veronica + Rei

 

• Veronica provides card draw and consistency.
• Sereniel focuses purely on damage.
• Rei compensates for AoE and tempo issues.

 

Deck Setup Examples

 

VII. Pull Advice & Manifest Ego

Should You Pull Sereniel?

Absolutely recommended. As the first limited unit, Sereniel offers top-tier damage, excellent flexibility, and long-term value.

If you already built Chizuru, Sereniel is a massive upgrade in break efficiency.

 

Manifest Ego Recommendations

Manifest Ego 1

 Boosts Pale Shooting Star damage and increases the number of Homing Laser activations.

 Primarily improves deck thinning and consistency; a minor but stable upgrade.

 

Manifest Ego 2

 Grants extra Homing Laser L at battle start and additional card draw when Homing Laser is drawn.

 A major power spike for opening turns, significantly improving burst and early Ravage potential.

 

Manifest Ego 3

 Increases Death Halo damage and grants Fast to Homing Laser L.

 Mainly useful against highly mobile enemies; overall impact is situational.

 

Manifest Ego 4

 Gains ATK on Ravage based on the number of Homing Laser cards in hand.

 Easy to trigger and offers a solid mid-fight damage boost.

 

Manifest Ego 6

 Deals massive bonus damage to enemies when allies trigger Ravage, scaling with enemy Tenacity.

 Extremely strong against elites and bosses; one of Sereniel’s highest ceiling upgrades

 

 Manifest Ego 2 is the best comfort and performance upgrade for most players.

If resources allow, Manifest Ego 6 is also highly recommended for boss-focused content.

 

VIII. Conclusion

Sereniel is a top-tier Instinct DPS with stable burst, exceptional break efficiency, and a smooth gameplay loop. She performs consistently across all content and requires minimal team dependency, making her one of the safest and strongest pulls available.

For players managing multiple characters or experimenting with different teams, OSLink’s multi-instance automation makes progression effortless—handling repetitive tasks while you focus on strategy and optimization.

Build Sereniel well, master her break windows, and she’ll carry you through even the toughest encounters with ease.
