Skills & Mechanics Analysis

Zero’s playstyle revolves around precision strikes and devastating area-of-effect (AoE) bursts. Her kit heavily rewards you for fighting enemies lower than your current level, making her an incredible tool for map clearing and speed-running content.

Basic Attack (Appraisal - Severance): A standard 5-hit combo dealing Cosmos damage. Her plunge attack (Appraisal - Break) deals AoE damage based on fall height, and perfectly timed dodges allow her to perform a Critical Riposte (Flash of Inspiration) that reduces enemy Break meters.
Resonance Skill (Appraise and Engrave): Zero performs three consecutive weapon strikes, leaps into the air, and fires an Esper Cannon. The Catch: If the first enemy hit is a lower level than Zero, she deals an additional instance of Cosmos damage.
Ultimate (Divide by Zero): A massive AoE nuke that deals multiple instances of Cosmos damage to all enemies caught within the area.
Redirect Skill (Rift Blossom): She detonates a spatial rift, dealing two quick bursts of Cosmos damage.
Core Passives:
- Anomaly Perception: When your active character gains Ultimate Energy, Zero restores HP equal to 50% of her Base ATK.
- Theopneustos: Flat out increases her Ultimate damage by 25%.

How to Play Zero: Zero is a burst-focused character. Your goal is to keep her level maxed out so her Resonance Skill naturally triggers its bonus damage on weaker enemies. Build up her Ultimate energy, group the enemies together, and unleash Divide by Zero to wipe the field in an instant.

Best Weapon

Tier	Weapon Name	Key Stats	Why it works
Best in Slot	The Rain That Shook the World (S-Rank)	Base ATK 512, CRIT Rate 22%	This is practically tailor-made for Zero's burst profile. It increases Cosmos DMG by up to 42% for Redirect Skills and Ultimates. Using a Redirect Skill boosts her Cycle Intensity for 15 seconds, supercharging her damage output. The high CRIT Rate sub-stat makes building her gear significantly easier.
Strong Alternative	Day Off	Massive ATK%	Great for generating Ultimate Energy on enemy kills (up to 5 times per Eclipse cycle) while providing a massive ATK% stat stick.
Strong Alternative	Fluff of Fearlessness	ATK Boost	Grants a massive ATK boost (up to 45%) for 10 seconds after casting an Ultimate, making it great for short, explosive rotations.

Best Gear (Cartridges / Modules)

To maximize Zero's burst potential, you want to buff her Cosmos damage and ensure her Ultimate hits as hard as possible.

Set Type	Set Name	Bonus Effect
2-Piece Bonus	Lost Radiance	Cosmos DMG +10%
4-Piece Bonus	Lost Radiance	Ignores 25% of enemies' DEF for 20 seconds after the wearer casts an Ultimate. This is non-stackable but incredibly powerful for a burst DPS like Zero.

Stat Type	Priority Recommendation
Main Stat	Cycle Intensity (环合强度)
Sub-stats	Cycle Intensity > CRIT Rate / CRIT DMG > DMG Bonus > ATK% > Flat ATK

Note: Cycle Intensity directly buffs her elemental reaction and cycle damage ceiling, making it the most valuable stat for her kit.

Best Team Compositions

Zero thrives in teams that can group enemies, provide ATK buffs, and keep the pressure on while her burst is on cooldown.

The Ultimate Eibon Burst Team

Character	Role	Synergy Analysis
Sakiri	Buffer/Grouper (The Setup)	Sakiri is the ultimate enabler. Using her Eating Mode and Devour Whole, she acts as a powerful crowd-control unit, pulling enemies into a tight cluster. Her Ultimate (Feast of Gluttony) roots enemies in place and triggers her passives to grant the entire team an ATK boost equal to 30% of Sakiri's Base ATK.
Jiuyuan	Sub-DPS/Control (The Primer)	While enemies are grouped, Jiuyuan dashes in to apply her Lethal Rose Pact. Her rapid Anima damage and Pact Detonations provide massive burst-control. Furthermore, her Unhindered Passage resonance reduces the Anima RES of marked targets.
Nanally	Main/Follow-up DPS (The Sustained DPS)	Nanally provides immense sustained damage through her Anima element and Underboss summons. Her kit is loaded with follow-up attacks that automatically trigger whenever the team deals Esper Cycle DMG, keeping the DPS high while setting the stage for Zero.
Zero	Burst DPS (The Executioner)	Zero enters the field to finish the job. Because Sakiri grouped the enemies and buffed the team's ATK, Zero can drop her Divide by Zero Ultimate directly into the cluster. Furthermore, when Zero triggers a Cosmos Esper Cycle, her Zero Display resonance grants the entire team an additional 10% ATK for 20 seconds, buffing Nanally and Jiuyuan for the next rotation.

Ascension / Leveling Materials

To push Zero to the Level 90 cap and fully max out all 4 of her skills, you will need a substantial amount of resources. Below is the complete, combined total of materials required for both her Breakthroughs and full skill upgrades:

Material Name	Total Amount Required	Primary Source(s)
Currency ($)	2,273,000	Quest Rewards, Instance Drops, World Exploration
Charging Knight Spark Plug	86	World Boss: Torrential Void
Paradoxical Whispers	83	Monster Drop (Industrial District), Simulation Center
Obscure Whispers	78	Monster Drop (Industrial District), Simulation Center
The Olive Branch	64	Skill Material Instance: Anima, Event Shop
Lost Whispers	57	Monster Drop (Industrial District), Simulation Center
Nestling's Longing	40	Skill Material Instance: Anima, Event Shop
Dove's Flutter	40	Skill Material Instance: Anima, Event Shop
Good Boy Stamp	32	Store Front, Instance Drops, World Exploration

Awakening (Constellation) Analysis

If you are pulling for duplicates, Zero has some of the most front-loaded and powerful Awakening nodes in the game.

Level	Node Name	Effect Details
A1	Blooming Gaze (High Priority)	Adds an extra hit of 200% ATK to enemies of a lower level on the first hit, and it ignores 75% of their DEF. This makes her map-clearing potential absolutely top-tier.
A2	Finding the Calling	Grants 8 Ultimate Energy after using her Resonance Skill. Good for rotation smoothness.
A3	Anomalies Record (Game-Changing)	Increases her Ultimate CRIT Chance by a massive 50%. This completely changes how you build her gear, allowing you to invest purely into CRIT DMG and Cycle Intensity.
A4	Undecided Factors	Converts every 1 point of Base ATK into a 0.1% damage boost for her Ultimate (up to 25%).
A5	Theopneustos	Increases her ATK by 10% for 20s when triggering a Support Skill.
A6	Deceptive Liberation	Increases the Extra DMG Ratio of her Resonance skill to 300% of her ATK.

Is Zero Worth Pulling?

Absolutely. Zero is an exceptionally powerful, self-sustaining S-Rank DPS who trivializes overworld exploration and speed-farming thanks to her "lower level" execution mechanics. If you manage to get her to A3, she becomes one of the easiest characters to build in the game due to the free 50% CRIT Rate on her Ultimate. If you need a Cosmos nuker who can slot seamlessly into fast-swap burst teams, Zero is a must-pull.

FAQ

Q: If I unlock Zero's A3, do I still need to build CRIT Rate on her gear?

A: You need very little! A3 gives her Ultimate a flat 50% CRIT Rate. Combined with her base 5% and potentially her signature weapon (The Rain That Shook the World, which gives 22%), you will effortlessly hit the CRIT cap for her burst. You should focus all your sub-stats on Cycle Intensity and CRIT DMG instead.

Q: How exactly does her "lower level" mechanic work?

A: Zero's Resonance Skill (and her A1 Awakening) checks her current character level against the enemy's level. If the enemy's level is strictly below hers, she deals massive bonus damage (and ignores DEF at A1). This means you should prioritize maxing out Zero's character level (currently Lv. 90) before investing heavily in her other stats, as this level advantage is core to her damage output.

Q: Does Zero provide any team utility, or is she strictly a selfish DPS?

A: While mostly a selfish burst DPS, she does have two great utility points: Her Anomaly Perception passive provides minor healing to the active character based on her ATK, and her Zero Display resonance buffs the entire team's ATK by 10% whenever she triggers a Cosmos Cycle.
