ZZZ 2.5 Banner Schedule & Jane Doe Overview

Version 2.5 releases December 30, 2025 at 11 AM UTC+8. Phase 1 (December 30, 2025 - January 21, 2026) features Zhao, an S-Rank Ice Defense agent. Phase 2 (January 21 - February 17, 2026) may include Ye Shunguang, an S-Rank Physical Attack agent, per community leaks—await official confirmation.

Jane Doe's base stats: HP 7788, ATK 805, DEF 606, Impact 86, Anomaly Mastery 150, Anomaly Proficiency 112. She's designed to trigger Assault anomaly effects rapidly through percentage-based damage. Players can Zenless Zone Zero polychrome recharge cheap fast through BitTopup for competitive rates and instant delivery.

Physical Anomaly Specialist Role

Jane Doe builds Physical Anomaly stacks through rapid hits, triggering Assault status for percentage-based damage over time. Unlike traditional DPS, she scales with Anomaly Proficiency, Anomaly Mastery, and Physical DMG—not CRIT stats. This makes her significantly more F2P-friendly.

Her Gnawed state (10s duration, 5s Flinch immunity) grants CRIT Rate +31% and CRIT DMG +50%, allowing respectable direct damage while maintaining anomaly focus. Physical Anomaly agents excel in Disorder teams where multiple anomaly types combine for amplified damage, particularly valuable against high-defense endgame enemies.

Best F2P Disk Drive Builds

Optimal Build: 4pc Fanged Metal + 2pc Freedom Blues

Zenless Zone Zero Fanged Metal and Freedom Blues disk drives for Jane Doe Physical Anomaly build

  • Fanged Metal 2pc: Physical DMG +10%
  • Fanged Metal 4pc: Squad Assault DMG +35% for 12s
  • Freedom Blues 2pc: Anomaly Proficiency +30

Alternative Build: 4pc Shockstar Disco + 2pc Swing Jazz

  • Shockstar Disco 2pc: Impact +6%
  • Shockstar Disco 4pc: Basic/Dash/Dodge Counter Daze +20%
  • Swing Jazz 2pc: Energy Regen +20%
  • Swing Jazz 4pc: Squad DMG +15% for 12s after Chain/Ultimate

Main Stat Priority

Position 4: Anomaly Proficiency (mandatory)

  • Largest single source of Anomaly Proficiency
  • Directly accelerates Assault stack application

Position 5: Physical DMG (mandatory)

  • Applies to both direct damage and Assault anomaly damage
  • Scales multiplicatively with other damage increases

Position 6: Anomaly Mastery or ATK%

  • Anomaly Mastery: Increases anomaly effect damage
  • ATK%: Boosts basic attacks and anomaly calculations
  • Choose based on which stat falls below target values

Target Stats: ATK 2200+, HP 9000+, DEF 800+, Anomaly Proficiency 360+, Anomaly Mastery 145+

Substat Priority

  1. Anomaly Proficiency (accelerates stack buildup)
  2. ATK% (universal value)
  3. PEN (overcomes enemy defense)
  4. Anomaly Mastery (amplifies anomaly damage)
  5. CRIT Rate (minimal value)

Discard: CRIT DMG, DEF%, HP% unless 3+ optimal substats present. Jane's Gnawed state provides temporary CRIT bonuses, making dedicated CRIT investment wasteful.

Farming: S-Rank disks unlock at Inter-Knot level 35 via Bardic Needle level 2. Farm through Routine Cleanup at Scott Outpost. Recycle unwanted disks for Master Copies to tune main stats.

F2P W-Engine Options

Sharpened Stinger (Signature S-Rank)

Zenless Zone Zero Sharpened Stinger W-Engine for Jane Doe with stats and passive effects

  • Base ATK: 48-713
  • Anomaly Proficiency: 36-90
  • Passive: Physical DMG +12% for 10s (3 stacks, triggers every 0.5s)
  • Performance: 15-20% better than A-Rank alternatives

Electro-Lip Gloss (Best A-Rank)

  • ATK +10%, DMG +15%
  • Straightforward damage without complex conditions
  • Recommended for most F2P players

Weeping Gemini (A-Rank Alternative)

  • Anomaly Proficiency +30 (4 stacks)
  • Best if Anomaly Proficiency below 360 after disks
  • Prioritizes faster Assault triggers over direct damage

Rainforest Gourmet (A-Rank Budget)

  • ATK +2.5% for 10s (10 stacks)
  • Incremental scaling through sustained combat

F2P vs. Signature Analysis

Sharpened Stinger outperforms A-Rank options by 15-20% in optimal conditions through higher base ATK and Anomaly Proficiency. The 36% Physical DMG bonus at full stacks significantly amplifies all damage. However, this gap narrows in teams with strong external buffs.

Decision Framework:

Constellation Synergy:

  • M1: Salchow Jump +1, Physical Anomaly Buildup Rate +15%, DMG +0.1% per Anomaly Proficiency (max 30%)
  • M6: Passion state CRIT Rate +20%, CRIT DMG +40%, Assault Physical DMG 1600% Anomaly Proficiency

Team Compositions

F2P Core Team

  • Jane Doe + Anby + Nicole

  • Bangboo: Magnetiboo, Bagboo, Booressure, Avocaboo
  • Anby provides Electro anomaly for Disorder
  • Nicole offers defense shred and team buffs
  • Fully accessible with standard banner agents

Assault-Focused Team

  • Jane Doe + Seth + Caesar
  • Bangboo: Bangvolver, Luckyboo, Magnetiboo, Officer Cui
  • Seth amplifies anomaly damage
  • Caesar provides shielding and interruption resistance
  • Requires limited S-Rank Caesar

Disorder Team

  • Jane Doe + Caesar + Burnice
  • Bangboo: Bangvolver, Luckyboo, Magnetiboo, Red Moccus
  • Burnice applies Fire anomaly for Disorder reactions
  • Highest damage ceiling
  • Requires two limited S-Rank agents

Optimal Rotations

  1. Start with secondary anomaly agent (Anby/Burnice/Grace) to apply status effect first
  2. Swap to Jane Doe at 80-90% anomaly buildup
  3. Trigger both Assault and Disorder simultaneously
  4. Use EX Special with Freedom Blues 4pc for -20% Anomaly RES (8s)
  5. Coordinate team ultimates during this debuff window
  6. Gnawed state activation = peak damage phase

Bangboo Selection:

  • Magnetiboo: Additional Electro buildup for Disorder teams
  • Bangvolver: Physical damage amplification for Assault teams
  • Luckyboo: Energy regeneration for faster ultimates

Jane Doe vs. Other Anomaly Agents

Jane Doe vs. Piper (Physical Anomaly)

  • Piper: Higher burst damage, spin-to-win playstyle
  • Jane Doe: Faster anomaly application, shorter rotations, better team flexibility
  • F2P advantage: Jane works with standard banner agents; Piper needs specific compositions

Jane Doe + Grace (Electro Anomaly)

  • Powerful Disorder synergy
  • Grace's ranged attacks complement Jane's melee focus
  • Strongest F2P Disorder composition (one limited agent + standard banner Grace)

Future-Proofing

Anomaly damage scales with enemy HP pools, making Jane increasingly valuable as endgame introduces higher HP bosses. Percentage-based damage bypasses defense scaling issues affecting traditional DPS agents.

Version 2.5's Zhao (Ice Defense) and potential Ye Shunguang (Physical Attack) don't compete with Jane's anomaly niche. Her specialization protects against immediate power creep.

Constellation Value:

  • M1: 15% Physical Anomaly Buildup Rate + scaling damage (substantial value)
  • M6: Luxury, not necessity
  • C0 remains competitive for F2P players

Pre-Farming Guide

Disk Drives (Inter-Knot Level 35+)

  • Farm Fanged Metal + Freedom Blues at Scott Outpost
  • Target: Anomaly Proficiency (pos 4), Physical DMG (pos 5), Anomaly Mastery/ATK% (pos 6)
  • Allocate stamina after character/W-Engine levels acceptable

Dennies: 2+ million required for max level, skills, disks

  • Sources: Daily commissions, Hollow Zero, events

Skill Materials: Enemy-specific drops

  • Plan farming routes for Jane's required materials
  • Available through story progression and repeatable zones

W-Engine Materials: A-Rank requires fewer resources than S-Rank

  • Reach level 50-60 before banner launch

Stamina Optimization

Daily Allocation:

  • 100% to disk drives during pre-farming (after stockpiling ascension materials)
  • Disk farming has highest variance—optimal stats may require hundreds of runs

Battery Items:

  • Save for double-drop events or limited-time opportunities
  • Avoid polychrome stamina refreshes unless approaching content deadlines

Double-Drop Events:

  • Rotate weekly through different material types
  • Plan intensive farming during relevant windows
  • Track material needs against event schedules

F2P Banner Pull Strategy

Pity System:

  • 90 pulls guarantee 5-star (50/50 for featured character)
  • Losing 50/50 guarantees featured character in next 90 pulls
  • Worst case: 180 pulls (14,400 polychromes)

Monthly F2P Income: 8,000-10,000 polychromes

  • Sources: Daily commissions, events, Shiyu Defense, exploration
  • Supports one guaranteed limited character every two months

W-Engine Banner: Separate pity, 80-pull guarantee

  • F2P should avoid—A-Rank alternatives provide 80-85% performance at zero cost
  • Invest polychromes in characters, not marginal W-Engine upgrades

Skip or Pull Decision

Pull if:

  • Lacking strong Physical Anomaly agent
  • Have compatible teammates (Anby/Nicole minimum, Seth/Caesar/Burnice optimal)
  • Enjoy melee-focused, rapid-attack playstyle

Skip if:

  • Invested heavily in Piper
  • Need to save for upcoming support agents
  • Prefer ranged or slower combat styles

Evaluation Framework:

  1. Current roster gaps
  2. Available synergistic teammates
  3. Upcoming banner schedule
  4. Personal gameplay preferences

Common Build Mistakes

Mistake 1: Prioritizing ATK% Over Anomaly Proficiency

  • Anomaly Proficiency accelerates status buildup
  • More frequent Assault triggers > marginal ATK% gains

Mistake 2: Building CRIT Rate/CRIT DMG

  • Gnawed state provides temporary CRIT bonuses (CRIT Rate +31%, CRIT DMG +50%)
  • Dedicated CRIT investment redundant
  • Allocate substats to Anomaly Proficiency or ATK%

Mistake 3: Poor Team Composition

  • Needs Disorder enablers (Anby/Grace/Burnice) or anomaly amplifiers (Seth/Nicole)
  • Avoid pairing with redundant Physical DPS
  • Jane requires field time for Assault stacks

Energy Recharge Trap

Jane generates energy efficiently through rapid attacks—dedicated Energy Recharge investment unnecessary. Swing Jazz 2pc Energy Regen +20% is a bonus, not primary goal. Ultimate timing matters more than frequency—coordinate with team buffs and vulnerability windows.

Endgame Performance

Shiyu Defense Floors 10+

  • High-HP enemies with significant defense favor anomaly damage
  • Percentage-based Assault bypasses defense scaling
  • Flinch immunity allows aggressive positioning

Optimal Teams: Jane + Grace + Nicole

  • Triggers Physical Assault + Electro Shock Disorder
  • Nicole's defense shred enhances all damage
  • Multiplicative scaling across team

Hollow Zero

  • Sustained damage output and self-sufficient kit
  • Flinch immunity reduces dodge reliance
  • Physical Anomaly consistent across enemy types (no resistance variations)

F2P Investment Priority

  1. Character Level + Skills (level 60, maxed core skills first)
  2. W-Engine (A-Rank to level 50-60)
  3. Disk Optimization (incremental improvements)

Constellation Consideration:

  • M1: Meaningful performance increase (15% buildup, scaling damage)
  • Requires additional pulls vs. securing different limited character
  • Prioritize roster diversity over constellation depth

FAQ

Is Jane Doe worth pulling in ZZZ 2.5 for F2P players? Strong value if lacking Physical Anomaly agent. Works effectively with standard banner teammates (Anby, Nicole). Anomaly scaling requires less perfect substats than CRIT-dependent DPS. Skip if heavily invested in Piper or saving for support agents.

What are the best F2P disk drives for Jane Doe? 4pc Fanged Metal + 2pc Freedom Blues. Main stats: Anomaly Proficiency (pos 4), Physical DMG (pos 5), Anomaly Mastery or ATK% (pos 6). Target ATK 2200+, Anomaly Proficiency 360+, Anomaly Mastery 145+.

When does the Jane Doe banner release in version 2.5? Version 2.5 launches December 30, 2025. Jane doesn't appear in confirmed Phase 1 (December 30 - January 21) featuring Zhao. Phase 2 runs January 21 - February 17, 2026—specific timing unconfirmed. Monitor official announcements.

Which W-Engine should F2P players use for Jane Doe? Electro-Lip Gloss (ATK +10%, DMG +15%) for best F2P performance. Weeping Gemini (Anomaly Proficiency +30) if below 360 total. Both perform 15-20% below signature Sharpened Stinger at zero polychrome cost.

What team compositions work best with Jane Doe? F2P core: Jane + Anby + Nicole. Premium: Jane + Seth + Caesar (max Assault) or Jane + Caesar + Burnice (Fire-Physical Disorder). All benefit from matching Bangboo support.

Should I farm disk drives before Jane Doe banner? Yes, pre-farm Fanged Metal + Freedom Blues at Inter-Knot level 35+. Target correct main stats first, optimize substats over time. Stockpile 2+ million Dennies and skill materials for immediate deployment.
