Zenless Zone Zero Sunna Banner Guide 2026: Worth Pulling?

Sunna Banner Overview: Key Details Before March 4

Banner launches February 6, 2026 at 11:00 AM UTC+8, ending March 4, 2026 at 11:59 AM UTC+8. This 26-day window features Sunna as primary S-Rank with A-Rank rate-ups: Nekomata, Lycaon, and Soldier 11. A-Rank pity guarantees one every 10 pulls.

Polychrome Cost and Pity Mechanics

S-Rank base rate: 0.6% per pull at 160 Polychromes each. Soft pity starts at pull 75, hard pity at 90. 50/50 system applies.

Worst-case costs:

• First 50/50 loss: 90 pulls × 160 = 14,400 Polychromes
• Guaranteed Sunna: 90 pulls × 160 = 14,400 Polychromes
• Total maximum: 28,800 Polychromes

Players with existing pity progress subtract from these totals. Need polychromes? Buy Zenless Zone Zero polychromes top up via BitTopup for competitive pricing and instant delivery.

Who Is Sunna? Character Profile

S-Rank Physical Support from Angels of Delusion faction. Functions as quick-swap buffer, not field-time DPS. Amplifies Physical damage dealers like Aria, Billy, and Anby.

Level 60 base stats: 7,896 ATK, 5,095 HP, 666 DEF, 110 Anomaly Mastery, 110 Impact.

Limited banner exclusive - won't enter standard pool immediately after rate-up ends.

Sunna Kit Analysis: Skills and Mechanics

Mesmerized: Guaranteed CRIT Burst

Deals 500% ATK as Physical DMG with guaranteed CRIT and +50% CRIT DMG bonus. 12-second duration enables multiple DPS rotation cycles.

Shiyu Defense Floor 12 testing: ~39,480 damage per activation at 7,896 ATK. Eliminates RNG variance.

Ether Veil and Physical DMG Stacking

Team-wide +50 ATK buff lasting 30 seconds. EX Special stacks Physical DMG at 12.5% per stack, max 25% at 2 stacks (40-second duration).

Bubblegum Barrage costs 70 Energy; Special Photography Technique costs 0 Energy for flexible management.

Energy Management

140% Energy Regen breakpoint enables ultimate every 15-18 seconds. This threshold transforms Sunna from periodic to consistent buffer.

Rotation: Deploy Sunna → EX Special → Ether Veil → Swap to DPS → Return for ultimate → Reapply Mesmerized → Repeat.

Meta Position and Tier Ranking

Sunna fills specialized Physical Support tier. Physical teams historically lacked dedicated support infrastructure.

Shiyu Defense Floor 12 testing shows 18-25% team DPS increases when replacing generic supports with Sunna in Physical comps.

Sunna vs Ellen Joe

Different roles entirely. Ellen = on-field Ice DPS. Sunna = quick-swap Physical Support.

Choose based on roster gaps: Need primary DPS (Ellen) or support for existing Physical agents (Sunna)?

Future-Proofing

Support characters maintain relevance longer than DPS. Sunna's guaranteed CRIT and percentage-based buffs scale with future Physical DPS power levels.

Best Team Compositions

Premium Physical Team

Aria - Billy - Sunna: Highest damage ceiling. Continuous Physical uptime through alternating DPS windows.

Rotation: Sunna EX Special → Ether Veil → Aria full combo → Billy burst → Sunna ultimate → Repeat.

Mid-Tier Budget Team

Aria - Anby - Sunna: Anby's Stun creates damage windows. Performs within 10-15% of premium setups with lower investment.

F2P Accessible

Ye Shunguang - Sunna - Zhao or Anby - Sunna - Trigger: Completely F2P-accessible using starter characters.

Bangboo

The Biggest Fan: 7,896 ATK, 110 Anomaly Mastery, 50% CRIT Rate, 100% CRIT DMG, 110 Impact. Optimal synergy.

Mindscape Investment Guide

M0 Baseline

Base kit provides full functionality: Mesmerized guaranteed CRIT, Ether Veil buffs, 25% Physical DMG stacking. F2P should stop here.

M1: Energy and DEF Reduction

+15 Energy every 180 seconds, -7% enemy DEF for 40 seconds (stacks 3× to -21%). Moderate upgrade, 6-8% damage increase.

M2: ATK Scaling

+10% ATK during Ether Veil (team-wide), enhances Cat's Gaze DMG by 200-300%. Strongest single-constellation power spike. High value for dolphins.

M4: Ultimate Damage

+18% squad DMG for 60 seconds after ultimate. Near-permanent uptime with 15-18 second cycling. Whale territory.

M6: Guaranteed CRIT Scaling

8 seconds guaranteed CRIT with CRIT DMG increased by 0.03% per ATK point. At 7,896 ATK: +237% CRIT DMG total. Whale-only luxury.

Recommendations

• F2P: M0 only
• Dolphin: M0-M2 stopping point
• Whale: M2-M4 for optimization

Pull Decision Framework

Account Progression Assessment

Early Game (Level 1-30): Skip. Prioritize versatile DPS over specialized supports.

Mid Game (Level 31-50): Pull if Physical teams are your strongest composition with invested characters.

Late Game (Level 51+): Pull for Shiyu Defense optimization if you have established Physical DPS.

Roster Gap Analysis

Pull if:

• You have invested Physical DPS (Billy, Anby, Aria at level 50+ with proper gear)
• Physical teams struggle to clear content
• You lack alternative support options

Skip if:

• No invested Physical damage dealers
• Strongest teams use Elemental damage
• Upcoming banners fill critical gaps

Polychrome Budget

28,800+ available: Guaranteed acquisition, decide on roster value alone.

14,400-28,800: Single pity attempt, 50/50 risk. Can you accept potential loss?

Under 14,400: High risk, insufficient for guaranteed S-Rank.

F2P Strategy

Skip unless you meet ALL criteria:

• Established Physical DPS at high investment
• No upcoming characters filling critical gaps
• 28,800+ Polychromes available
• Physical teams = primary strategy

Skip Conditions

Definitively skip if:

• Roster lacks invested Physical dealers
• Can't reach 28,800 Polychromes before March 4
• Strongest teams use Elemental damage exclusively
• Saving for confirmed future characters

Performance Testing Results

Shiyu Defense Clear Times

Floor 12 with Aria-Billy-Sunna: 90-110 seconds vs 115-140 seconds with generic supports. 20-25% time reduction.

Metrics:

• Mesmerized procs: 39,480 damage average
• Team DPS increase: 18-25% vs Nicole/Rina
• Ultimate cycling: 15-18 second intervals at 140% Energy Regen

Deadly Assault Scoring

Physical teams with Sunna achieve 15-20% higher scores vs generic supports due to guaranteed CRIT eliminating RNG variance.

Common Misconceptions Debunked

Myth: Requires Full Premium Team Reality: Budget comps with Anby-Sunna-Trigger achieve 70-75% of premium damage with zero limited investment beyond Sunna.

Myth: Powercrept on Release Reality: Only dedicated Physical Support currently available. Occupies unique niche, not competing with DPS for slots.

Myth: Signature W-Engine Mandatory Reality: Weeping Cradle achieves 85-90% performance. 140% Energy Regen reachable with Drive Disc substats.

Actual Investment Requirements

• Character acquisition: 0-28,800 Polychromes
• Promotion to 60: 800,000 Denny, seals
• Skills to 12: 500,000 Denny, chips, 1 Hamster Cage Pass
• Drive Disc farming: 2-3 weeks stamina
• Total Denny: ~1,700,000

Polychrome Optimization
