As a dedicated player of Zenless Zone Zero, I've been closely following the game's evolution since its launch. Ellen, the formidable S-Rank Ice Attacker, made a striking debut during the 1.0 version's Mellow Waveride Banner. While her initial featured banner has concluded, the cyclical nature of the game's banner schedule assures us that she will return, giving both new and veteran players another chance to add this powerful agent to their roster. For those aiming to prepare for her eventual rerun, understanding her complete kit, material requirements, and upgrade paths is crucial to unlocking her full, chilling potential on the battlefield.

Deconstructing Ellen's Core Kit

Ellen is defined by her Ice Attribute, Attack Speciality, and Slash-type Damage. Her rarity as an S-Rank agent immediately signals her high ceiling for power. At the heart of her playstyle are her Core Skills, which synergize to create a devastating damage-dealer focused on critical hits and sustained offensive pressure.

Her primary Passive Core Skill, Sharp Toothed, is the cornerstone of her damage output. It grants a massive 50% increase in Crit Damage when she executes specific moves: a charged scissor strike during her Dash Attack: Arctic Ambush, or when she consumes a Flash Freeze Charge to activate Basic Attack: Flash Freeze Trimming. This mechanic encourages a deliberate, charge-building playstyle to maximize critical strike potential.

Her secondary Core Skill, Rising Storm, introduces a powerful team-based ramp-up effect. When another squad member shares either her Ice Attribute or her Faction, Ellen's Ice Damage gets a 3% boost for 10 seconds every time she deals Ice Damage. This effect can stack up to 10 times, and refreshing the stack resets the duration. This means, with proper team composition and sustained combat, Ellen can achieve a permanent 30% damage increase, making her a true late-fight menace.

Her Core Skill Enhancements, unlocked through progression, further amplify her strengths by systematically boosting her Crit Rate and Base Attack while leveling up her Sharp Toothed skill.

The Grind: Ellen's Promotion Materials

To elevate Ellen's base stats—Attack, HP, and Defense—you must gather specific Promotion materials. For Ellen, the grind heavily focuses on Offense Certification Seals. The total investment to promote her to maximum level is substantial and requires foresight and resource planning.

Here is the complete list of Ellen Promotion materials needed:

• Basic Offense Certification Seal x4

• Advanced Offense Certification Seal x32

• Pioneer's Certification Seal x30

• 800,000 Dennies

Breaking it down per level helps in pacing your farming. Early levels demand Basic Seals, which eventually give way to the more scarce Advanced and Pioneer Seals. Farming these materials from designated Commission stages should be a priority long before Ellen's banner arrives.

Mastering Her Arts: Skill & Attack Materials

Promotion is only half the battle. To truly master Ellen's techniques, you must invest in leveling her Attacks and Core Skill. This requires a different, and arguably more demanding, set of resources centered on Freeze Chips and the ominously named Murderous Obituary data.

The total cost to max all of Ellen's abilities is a testament to her S-Rank status:

For Core Skill Upgrades:

• Dennies: 405,000

• Higher Dimensional Data: Murderous Obituary x60

• Ferocious Grip x9

For Basic/EX/Special/Chain Attack Upgrades:

• Basic Freeze Chip x25

• Advanced Freeze Chip x75

• Specialized Freeze Chip x250

• Hamster Cage Pass x5

• Dennies: 2.5 million

Grand Total for All Skills:

• Hamster Cage Pass x5

• Ferocious Grip x9

• Higher Dimensional Data: Murderous Obituary x60

• Basic Freeze Chip x25

• Advanced Freeze Chip x75

• Specialized Freeze Chip x250

• Dennies: 2.9 million

The sheer volume of Specialized Freeze Chips and Dennies required highlights the endgame commitment needed. I recommend focusing on one skill branch at a time, perhaps prioritizing her Core Skill and EX Special Attack for immediate impact.

The Power of Constellations: Mindscape Cinema

Ellen's true peak performance is locked behind her Mindscape Cinema (MC), unlocked by obtaining duplicate copies of her through the gacha system. Each level provides a transformative upgrade, fundamentally altering or enhancing her mechanics. Here’s a breakdown of her cinematic power-ups:

Mindscape Level	Name	Effect
MC1	Glacial Omen	Dramatically increases Flash Freeze Charge gain from Dash Attacks and adds a stacking Crit Rate buff per charge consumed.
MC2	Arctic Ocean Predator	Allows direct EX Special follow-ups and massively boosts EX Special Crit Damage based on Flash Freeze Charges.
MC3	Overtime Intolerant	+2 levels to Basic Attack, Dodge, Assist, Special Attack, and Chain Attack.
MC4	Endless Hoarfrost	🎯 Game-Changer! Team Freezes/Stuns grant Ellen 6 Flash Freeze Charges, Quick Charge, and Energy. Enables incredible synergy with support units.
MC5	Adequate Sleep	Another +2 levels to key skills (same as MC3).
MC6	The Feast Begins	Grants Penetration Ratio and a stacking buff that culminates in a 250% damage nuke on a Charged Scissor Strike.

Key takeaways from her Mindscape Cinema:

• MC1 smooths her energy/charge economy.

• MC2 & MC6 synergize to create monstrous EX Special and finisher damage.

• MC4 is arguably her most important constellation, turning her into a relentless engine of destruction when paired with freezing allies. It solves any potential charge generation issues and adds significant utility.

In my experience, even getting Ellen to MC2 provides a noticeable power spike, while MC4 unlocks a completely new tier of team composition and fluidity. Planning your savings for potential duplicates during her rerun is a strategy for the most dedicated commanders.

Final Thoughts and Preparation Strategy

Looking ahead to 2026 and beyond, Ellen remains a top-tier Ice damage dealer in Zenless Zone Zero's meta. Her combination of scalable damage, critical focus, and powerful Mindscape upgrades ensures her longevity. For players awaiting her return, the preparation checklist is clear:

1. Farm Seals & Chips: Start stockpiling Offense Certification Seals and Freeze Chips from daily commissions.

2. Save Dennies: The nearly 3.7 million Dennies total cost is no joke. Participate in all Dennie-yielding activities.

3. Plan Your Team: Identify Ice or Faction-matching allies (like Lycaon or Soukaku) to activate Rising Storm.

4. Manage Expectations: Her full build is a marathon, not a sprint. Focus on key promotion and skill levels first.

Ellen is more than just a powerful character; she represents a rewarding investment for any commander who enjoys a high-skill, high-reward playstyle centered on precision and overwhelming force. When the Mellow Waveride banner sails back into view, you'll be ready to welcome the glacial predator with open arms and a fully stocked inventory. ❄️⚔️
