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

With the launch of the Galactic Disaster Season 2 Seed of Karmic Fire, the overall meta of Chaos Zero Nightmare has shifted noticeably. This guide focuses on Nine, the new Exhaust & Counterattack–oriented Vanguard, providing a full breakdown of her role, core mechanics, card builds, team compositions, and pull recommendations—helping you quickly determine Nine’s real combat value and long-term investment potential.

 

 

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. Nine Overview

Attribute & Role

Nine is an Order-attribute Vanguard DPS focused on high-cost, single-target burst built around the Exhaust mechanic.

Her damage curve leans heavily toward late-fight scaling and requires consistent card draw and controlled Exhaust timing.

 

Core Mechanic

Nine’s entire kit revolves around Exhaust interactions.

Her main damage source is the scaling attack card Hew. Each time an Exhaust effect successfully triggers, Hew levels up, significantly increasing its damage and effects.

Once Hew is used at its highest level, it resets back to Level 1. In practice, without proper draw and Exhaust pacing, her damage ceiling drops sharply.

 

II. Nine Card Builds

Basic Cards

 

Recommend to Keep

• Slash

After unlocking Potential 03-1, Slash increases the damage of Exhaust cards and becomes a core support tool.

 

Recommend to Remove

• Blade Back Block

Defensive value is limited and offers little synergy with Nine’s damage engine.

 

Epiphany Cards & Priority

Hew

 

Nine’s core attack card. Starts at Level 1 and levels up after each Exhaust trigger. At the maximum level, using Hew resets it back to Level 1.

 

Epiphany Priority:

2 > 4 > 5 > 3 > 1

• Hew (2) – Raises the maximum level from 3 to 5, significantly boosting burst potential.
• Hew (4) – Changes the target to all enemies, improving multi-target coverage.
• Hew (5) – Triggers automatically when allies perform Counterattack actions, ideal for Counterattack teams.

The remaining options are niche and generally not recommended.

 

Experienced Strike

 

A 1-cost attack card that grants a shield and increases Exhaust card damage.

 

Epiphany Priority:

1 > 5 > 2 > 3 > 4

• Experienced Strike (1) – Strong general upgrade with excellent flexibility.
• Experienced Strike (5) – Grants Counterattack, enabling Counterattack-oriented builds.
• Experienced Strike (2) – Pure damage increase.

Other options offer limited overall value.

 

Fatal Strike

 

A 1-cost attack card that increases its damage based on the highest-cost card in your hand, then Exhausts that card to accelerate setup.

 

Epiphany Priority:

1 > 5 > 3 > 4 > 2

• Fatal Strike (1) – Best all-around upgrade.
• Fatal Strike (5) – Gains bonus damage based on the number of allies with Counterattack.
• Fatal Strike (3) – Instantly upgrades Hew in hand to its highest stage. Strong when paired with Level-5 Hew, but requires cost control through Exhaust.

 

Counterblade

 

A buff card that grants Honed Edge whenever a shield is gained. Honed Edge increases attack card damage and stacks up to 3 times.

 

Epiphany Priority:

5 > 4 > 3 > 1 > 2

• Counterblade (5) – Automatically triggers Hew once per turn, greatly accelerating stacking and providing stable damage.
• Counterblade (4) – Grants Honed Edge when Counterattack is obtained, and makes the damage bonus apply to all allies—ideal for Counterattack teams.
• Counterblade (3) – Adds an additional Initiation effect, improving early-turn setup.
• Counterblade (1) – Grants Honed Edge when an Exhaust card is used, making it easier to trigger.
• Counterblade (2) – Only increases shield value and offers minimal impact.

 

III. Potential Priority

• 03-1 – Enables Slash to increase Exhaust card damage
• 07 – Increases Order damage
• 04 → 05 → 06 – Damage and shield-scaling Potentials
• 02, 05-1 – Basic card enhancements (low priority)

Neutral card Potentials can be safely skipped.

 

 

IV. Partner Recommendations

Exclusive Partner

Alcea

• Increases DEF
• Increases the damage of the next attack card after an Exhaust trigger
• Directly aligns with Nine’s core mechanic

 

Alternatives

Eishlen

• Increases shield values
• Increases damage after gaining Counterattack

 

Wilhelmina

• Increases DEF
• Deals increased damage to enemies affected by Vulnerable

 

 

V. Memory Fragment Setup

Set Recommendation

• 4× Beast’s Yearning
• 2× Tetra’s Authority

Beast’s Yearning significantly boosts Order-attribute Exhaust damage and is essentially tailor-made for Nine.

Tetra’s Authority provides much-needed defensive stability.

 

Stat Priority

Main Stats

• Slot 4: Crit Rate
• Slot 5: Order DMG or DEF
• Slot 6: DEF

Substats

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

 

VI. Team Compositions

1. Nine + Narja + Khalipe

 

• Narja provides healing, damage amplification, and cost-reduction tools to relieve AP pressure.
• Khalipe applies Vulnerable, significantly amplifying Nine’s burst.
• Khalipe’s Celestial cards are easily triggered by Nine’s high-cost plays.

A stable core that balances damage and survivability.

 

2. Nine + Magna + Maribell

 

• Both Magna and Maribell gain Counterattack at the start of each turn.
• This rapidly stacks Honed Edge for Nine and greatly boosts Fatal Strike damage.
• Magna also applies Vulnerable, further amplifying team damage.

This setup is currently Nine’s strongest synergy for Counterattack-oriented builds.

 

VII. Pull Advice & Manifest Ego

Nine’s current performance is largely numbers-driven, but she benefits heavily from the new seasonal equipment and card mechanics introduced in Seed of Karmic Fire.

The current environment strongly favors Exhaust-based damage patterns, and Nine scales well as more seasonal support tools become available. Overall, Nine is a recommended pull for players looking for a scaling main DPS with strong future potential.

 

Regarding Manifest Ego:

• E1 

Allows cards triggered by Fighting Spirit to select their targets, greatly improving consistency.

• E2

Grants one Exploit Opening at the start of battle, dealing Tenacity Damage and applying Vulnerable.

If you plan to invest further into Nine, E1 and E2 offer the highest return.

 

 

VIII. Conclusion

Nine is a high-scaling Vanguard built around clean Exhaust timing and late-fight burst.

As seasonal equipment and card mechanics continue to expand, her performance ceiling is expected to rise further. If you enjoy high-impact burst playstyles and are looking for a main DPS that benefits directly from the current seasonal meta, Nine is a solid and future-proof investment.

If you enjoy testing multiple builds or managing several teams at once, OSLink’s multi-instance automation can greatly reduce the grind—handling repetitive tasks while you focus on optimization and strategy.

Let OSLink handle the routine, and spend your time where it matters most: smart team building and decisive combat choices.
