Maximize Your Assault Damage With the Best Jane Doe Build in Zenless Zone Zero

Jane Doe is the premier Physical Anomaly Agent in Zenless Zone Zero, capable of shredding enemy health bars through rapid Physical Anomaly Buildup and high-frequency "Assault" (Strong Attack) triggers. Unlike traditional Attack-type agents who rely on Crit Rate and Crit DMG from gear, Jane Doe scales primarily with Anomaly Proficiency. Her unique kit allows her Physical Anomaly triggers to critically hit—a mechanic exclusive to her—making her building process distinct and highly rewarding for those who optimize her stats correctly.

The following analysis provides the definitive build for Jane Doe, covering W-Engines, Drive Discs, skill priorities, and the mathematical logic behind her most effective team compositions.

Understanding Jane Doe Core Mechanics and the Passion State

Before diving into gear, one must understand how Jane Doe generates damage. Her gameplay revolves entirely around the Passion Stream gauge.

The Passion State Logic

When Jane Doe uses her Basic Attacks, Dodges, or Specials, she accumulates Passion Stream. Once the gauge is full, she enters the Passion state. In this state:

• Her Physical Anomaly Buildup rate increases significantly (by 25% or more depending on skills).
• Her Attack is increased based on her Anomaly Proficiency (AP).
• She gains access to her enhanced Basic Attack: Salchow Jump, which allows her to perform a continuous spinning attack that rapidly stacks Physical Anomaly.

The Assault Crit Mechanic

Jane’s Core Passive, "Insight," is what makes her the "Queen of Anomaly." It allows the "Assault" effect (triggered when Physical Anomaly hits 100%) to critically hit.

• Base Crit Rate: Proportional to Anomaly Proficiency.
• Crit Damage: Fixed at 50% extra damage but can be enhanced by specific buffs. To maximize this, a Jane Doe build must aim for a specific Anomaly Proficiency threshold to ensure consistent "Assault" crits.

Best W-Engines for Jane Doe

Choosing the right W-Engine is the single most impactful decision for Jane Doe's output. While her signature weapon is tailor-made for her, several F2P and alternative S-Rank options perform admirably.

1. Sharpened Stinger (Signature S-Rank)

This is the undisputed best-in-slot (BiS) option. It provides a massive boost to Anomaly Proficiency as its secondary stat and features a passive that grants "Predatory Instinct" stacks upon performing dash attacks.

• Performance Note: At maximum stacks, it increases Physical DMG by 36% and Anomaly Buildup Rate by 40%. Since Jane Doe constantly dodges and uses dash attacks, maintaining 100% uptime on these buffs is effortless.

2. Fusion Compiler (Alternative S-Rank)

Originally designed for Grace, this W-Engine is surprisingly potent on Jane. It offers PEN Ratio as a secondary stat and boosts Anomaly Proficiency whenever the equipper uses a Special Attack.

• Trade-off: While the raw stats are high, Jane Doe doesn't use her Special Attack as frequently as Grace, meaning you may need to adjust your rotation to keep the AP buffs active.

3. Electro-Lip Gloss (A-Rank Battle Pass)

For players who purchase the New Eridu City Fund, this is her best A-Rank choice. It provides Anomaly Proficiency and increases ATK and DMG when an enemy is afflicted with an Attribute Anomaly.

• Experience Tip: Since Jane triggers Assault almost every 3-4 seconds, the enemy is almost constantly under an anomaly state, making this buff very reliable.

4. Weeping Gemini (F2P/Craftable)

This is the go-to option for F2P players. It can be purchased from the Gadget Store. It provides a stacking AP buff whenever any squad member triggers an Anomaly.

• Mathematical Context: In a "Disorder" team where you switch between Jane and another Anomaly agent (like Burnice), this weapon reaches its maximum potential extremely quickly.

Optimal Drive Disc Sets and Stats

Drive Discs are where you fine-tune Jane Doe's scaling. The goal is to reach the Anomaly Proficiency "soft cap" while maintaining enough Anomaly Mastery for fast triggers.

The Best 4-Piece Set: Fanged Metal

Fanged Metal is non-negotiable for a high-end Jane Doe build.

• 2-Piece Bonus: Physical DMG +10%.
• 4-Piece Bonus: Whenever a squad member inflicts Assault on an enemy, the equipper deals 35% increased damage to the target for 12 seconds. Given that Jane Doe is the one inflicting Assault, she essentially maintains a permanent 35% DMG multiplier throughout the fight.

The Best 2-Piece Complement

1. Freedom Blues: Provides +30 Anomaly Proficiency. This is the standard choice to help Jane reach the required AP thresholds for her passive.
2. Chaos Jazz: Also provides +30 Anomaly Proficiency. It is interchangeable with Freedom Blues if the substats are better.

Recommended Main Stats

• Partition 4: Anomaly Proficiency (Mandatory). This is the core of her damage scaling.
• Partition 5: Physical DMG% or ATK%. Physical DMG% generally scales better in the endgame, but a high-roll ATK% disc can be a placeholder.
• Partition 6: Anomaly Mastery. This stat dictates how fast you fill the enemy's Anomaly circle. Faster fills mean more Assault triggers.

Substat Priority

1. Anomaly Proficiency: Every single point counts until you hit at least 420 AP.
2. ATK%: Increases the base damage that Assault scales from.
3. PEN Ratio: Useful for high-defense bosses in Shiyu Defense.
4. Flat ATK: A secondary but welcome boost.

Note: Crit Rate and Crit DMG substats are largely wasted on Jane Doe because her only crits (Assault) are governed by her AP-based passive, not your gear's Crit stats.

Skill Leveling Priority

Jane Doe’s damage distribution is heavily weighted toward her Basic Attacks and her Core Passive.

1. Core Skill (Highest Priority): This upgrades the "Insight" passive, increasing the conversion rate of AP to ATK and the crit scaling of Assault. Level this as soon as materials allow.
2. Basic Attack: Since Jane spends 90% of her time on-field performing basic attack combos and the "Salchow Jump" during the Passion state, this is her primary active damage source.
3. Dodge: Her dash attacks are crucial for maintaining Passion Stream and triggering W-Engine passives.
4. Special Attack / Ultimate: These provide high burst and instant Passion energy but are secondary to the sustained output of her basic combos.

Best Team Compositions for Jane Doe

Jane Doe thrives in teams that can either buff her Physical output or provide a second element for "Disorder" procs.

1. The PubSec Assault Team (Jane + Seth + Rina/Lucy)

This is the most popular and consistent team.

• Seth Lowell: Seth provides a shield that grants the protected character a flat Anomaly Proficiency buff (up to 100 AP). He also shreds enemy Anomaly Resistance.
• Rina: Provides PEN Ratio buffs, which significantly increase the impact of Jane’s Assault hits.
• Lucy: Provides a flat ATK buff that scales well with Jane’s high frequency of attacks.

2. The Disorder Powerhouse (Jane + Burnice + Seth)

This team focuses on "Disorder"—the damage explosion that occurs when one Attribute Anomaly replaces another.

• Burnice (Fire Anomaly): Burnice applies off-field Fire buildup. When Jane triggers Assault on a burning enemy, it triggers Disorder, dealing a massive chunk of damage based on the remaining Burn duration.
• Rotation: Start with Burnice to apply Scorched, then switch to Jane via Seth’s Quick Assist to carry over the AP buff and trigger repeated Assaults and Disorders.

Practical Gameplay and Rotation Tips

To play Jane Doe like a pro, you must master the "rhythm" of her Passion state.

Managing the Passion Stream

Do not waste your Passion state. If the enemy is about to go into a phase transition or invulnerability, avoid filling the gauge. Wait until the enemy is vulnerable, then use her Ex Special Attack or Ultimate to instantly enter the Passion state and unleash the Salchow Jump (Hold Basic Attack).

The Multi-Dodge Advantage

Jane Doe is the only character who can perform multiple dodges in rapid succession without the usual cooldown "stumble." Use this to stay glued to the enemy. Perfect Dodges are the fastest way to recover Passion Stream while in the Passion state, allowing you to extend her enhanced window indefinitely if played skillfully.

The 420 AP Goal

In our testing, reaching 420 Anomaly Proficiency is the "sweet spot." This value maximizes the conversion from her Core Passive and ensures that her Assault crits are consistent. If you are below 300 AP, Jane will feel significantly weaker than a traditional Attack agent. Prioritize AP over every other stat until you hit this mark.

Summary of the Best Jane Doe Build

FAQ

Why shouldn't I build Crit Rate on Jane Doe? Jane's special "Assault Crits" do not use your character's Crit Rate stat. Instead, they use a hidden calculation based on your Anomaly Proficiency. Building Crit Rate on her Drive Discs only affects her very weak physical slashes, not the massive 200k+ Assault procs that make up her main damage.

Is Anomaly Mastery better than Anomaly Proficiency? They serve different purposes. Anomaly Mastery (Slot 6) makes the "circle" fill faster, meaning you trigger Assault more often. Anomaly Proficiency increases the actual damage number when that circle fills. You need a balance, but generally, Mastery is only taken on Slot 6, while Proficiency is stacked everywhere else.

Can Jane Doe work without Seth? Yes, she can work with other supports like Lucy or Rina, but Seth is her best partner because his AP buff is tailored specifically for Anomaly agents. Without him, reaching the 420 AP threshold is much harder and requires perfect Drive Disc rolls.

How does "Disorder" damage work with Jane? Disorder occurs when you trigger a new Anomaly (e.g., Physical/Assault) while a previous one (e.g., Fire/Burn) is still active. The game calculates the remaining damage of the first Anomaly and triggers it all at once with a bonus multiplier. This makes Jane paired with Burnice or Grace extremely effective against high-HP bosses.

By following this build, Jane Doe becomes an unstoppable force in New Eridu, capable of solo-clearing endgame content like Shiyu Defense with ease. Focus on her Anomaly Proficiency, keep her in the Passion state, and watch the "Assault" numbers fly.
