The Ultimate Guide to Grace: Mastering Zenless Zone Zero's S-Rank Electric Anomaly Agent

As we navigate the neon-drenched streets of New Eridu in 2026, one name continues to electrify the strategic meta of Zenless Zone Zero: Grace. From her explosive debut during the game's 1.0 launch, this S-Rank Agent with the Anomaly speciality has carved out a formidable niche. I've spent considerable time analyzing her mechanics, and what sets Grace apart is her unique role as a high-voltage anomaly specialist who deals piercing damage, a combination as potent and volatile as a live wire submerged in water. She's not just another damage dealer; she's a precision instrument for applying debilitating Shock effects. While she is a permanent fixture in the Star-Studded Cast Banner, securing her often comes down to that nail-biting 50/50 chance on limited-time banners. For those who successfully pull her, the journey to unlocking her full, crackling potential begins here.

Grace's Core Kit: A Symphony of Sparks

Understanding Grace's abilities is akin to learning the intricate wiring of a complex supercomputer. Her foundation is built on her Piercing Electric damage type, but the real magic lies in her Passive Core Skill, Pre-Driven Needle. This ability functions like a capacitor bank, methodically storing energy with each hit from her Basic or Dash Attacks (which deal Physical damage). For every strike, she gains one stack of Zap, capping at eight. Once fully charged, unleashing a Special or EX Special Attack discharges this accumulated energy, supercharging the target's Electric Anomaly Buildup by a staggering 65%. This mechanic makes her an unparalleled setup agent for devastating chain reactions.

Her supporting skill, Tech Anomaly Dept., further cements her team-oriented role. It activates when a squad member shares her Attribute (Electric) or Faction. Upon hitting an enemy with an EX Special Attack, it primes the target, making the next applied Shock effect deal 18% more damage. This effect can stack twice per skill use, turning a simple shock into a catastrophic lightning storm.

To maximize her core capabilities, you must invest in her Core Skill Enhancements. These upgrades, labeled A through F, systematically boost her Base Attack and Anomaly Mastery while increasing the level of her crucial Pre-Driven Needle skill. The progression is as follows:

Building Grace: The Material Grind

Elevating Grace's base stats of Attack, HP, and Defense requires a dedicated hunt for specific Promotion materials. Her upgrade path is a targeted one, demanding a significant investment in Controller and Anomaly Certification Seal components. Think of this process as gathering the specialized parts for a custom-built railgun—every piece is essential.

The total materials needed to promote Grace to her maximum level are:

• Basic Anomaly Certification Seal x4

• Advanced Anomaly Certification Seal x32

• Controller Certification Seal x30

• Dennies x800,000

Beyond her base stats, unlocking the true fury of her skills requires a separate and substantial investment in Skill and Attack materials. This is where you fine-tune her electrical output, requiring a stockpile of Shock Chips and Destructive Advance data modules. The total cost to fully master her abilities is daunting but ultimately transformative.

Grand Total for All Ability Upgrades:

• Hamster Cage Pass x5

• Living Drive x9

• Higher Dimensional Data: Destructive Advance x60

• Basic Shock Chip x25

• Advanced Shock Chip x75

• Specialized Shock Chip x250

• Dennies x2.9 Million

A breakdown of these costs reveals the scale:

• For Core Skill Upgrades Alone:

• 405,000 Dennies

• Higher Dimensional Data: Destructive Advance x60

• Living Drive x9

• For Attack Upgrades Alone:

• Basic Shock Chip x25

• Advanced Shock Chip x75

• Specialized Shock Chip x250

• Hamster Cage Pass x5

• 2.5 Million Dennies

Mindscape Cinema: The Path to Perfection

The pinnacle of optimizing Grace lies in her Mindscape Cinema, unlocked by obtaining duplicate copies of her to acquire Agent Focus. Each level is a major breakthrough, refining her into a more precise and devastating instrument. Her cinematic upgrades are not mere stat bumps; they are fundamental evolutions of her playstyle, transforming her from a powerful agent into a tactical centerpiece as indispensable as the central processor in a city's power grid.

Here is the full sequence of Grace's Mindscape Cinema:

1. Recharge Chamber (MC1): The fourth hit of her Basic Attack grants 0.25 Energy to all squad members. This can provide up to 2 Energy total per move cycle, supercharging team synergy.

2. Lightning Piercer (MC2): Her grenade hits (from Basic, Special, or EX Special Attacks) now shred the target's defenses, reducing Electric Resistance and Electric Anomaly Buildup Resistance by 8.5% for 8 seconds.

3. Chief Mechanic (MC3): A massive +2 level increase to Basic Attack, Dodge, Assist, Special Attack, and Chain Attack skills.

4. Burst Capacitor (MC4): Using her EX Special Attack grants 6 stacks of Charge. Her Basic or Dash Attacks then consume these stacks to boost their Energy Generation Rate by 20% per stack, creating a self-sustaining energy loop.

5. "Frosty Cold Iron Witch" (MC5): Another comprehensive +2 level increase to her core combat skills.

6. Detonation Trigger (MC6): The grand finale. When consuming all 8 Zap stacks for a Special or EX Special Attack, the skill is enhanced, throwing an extra grenade and boosting each grenade's damage to 200%. This turns her ultimate setup into an apocalyptic detonation.

Mastering Grace is a commitment, a long-term project of gathering rare components and strategic duplicates. Yet, for players willing to undertake this journey, the reward is an Agent capable of controlling the battlefield with calculated bursts of overwhelming electric power. In the ever-evolving chaos of New Eridu, a fully-built Grace is less of a character and more of a force of nature—a directed storm waiting for your command. Good luck, Proxies. The city's lights are counting on you.

Data referenced from Game Developer helps frame why Grace’s kit feels so uniquely “systemic”: her Zap stacking and Shock amplification function like a resource loop that rewards deliberate sequencing (building stacks with safe basics, then cashing out with Special/EX for accelerated anomaly buildup). Thinking in terms of combat design patterns—setup, payoff, and team-triggered synergies—also clarifies why her value spikes in squads that can repeatedly cycle EX windows to keep Shock pressure high while leveraging her faction/attribute triggers for amplified procs.
