Zenless Zone Zero Sunna Banner Guide: Pull or Skip for Aria?

Banner Overview: Release Date & Pity System

Version 2.6 Schedule

Sunna's banner runs Feb 6 (11:00 AM UTC+8) through Mar 4, 2026—27 days before Aria's Phase 2 debut. The 154cm Angels of Delusion agent creates tight resource pressure for players managing limited Polychromes.

Pity carries forward from previous banners. Planning to pull? Buy Zenless Zone Zero polychromes via BitTopup for competitive rates and instant delivery.

Pity Mechanics

Signal Search operates at 0.6% base S-Rank rate (160 Polychromes/pull):

• Soft pity: Starts pull 75 with increasing rates
• Hard pity: Guaranteed S-Rank at pull 90
• 50/50 system: First S-Rank = 50% Sunna, 50% standard pool
• Guaranteed: Second S-Rank (if first lost) = 100% Sunna
• Worst case: 180 pulls (28,800 Polychromes)

Polychrome Costs

• Best case: 160 Polychromes (single pull)
• Average: 12,000-14,400 (75-90 pulls, 50/50 win)
• Worst case: 28,800 (180 pulls, 50/50 loss)

F2P income in 2.6: 8,000-12,000 Polychromes from dailies (60/day), Shiyu Defense (300 biweekly), events. Barely covers one soft pity—making Sunna vs Aria critical for non-spenders.

Complete Kit Breakdown

Basic & EX Special

Sunna's kit centers on Physical amplification via Mesmerized state and Ether Veil buff. EX Special Bubblegum Barrage costs 70 Energy, setting up rotations. Special Photography Technique requires 0 Energy for flexible combos.

Mesmerized delivers 500% ATK Physical damage with guaranteed crits and +50% CRIT DMG (12s duration). Max level stats: 7,896 ATK, 5,095 HP, 666 DEF, 110 Anomaly Mastery, 110 Impact.

Ultimate & Team Buffs

Ultimate triggers Ether Veil Idol: +50 ATK (30s) and +30% Stun DMG Multiplier (40s) for all squad members.

Angelic Chord-ination passive: 15 Energy on entry (max 3,500 ATK requirement), +30% initial ATK buff (40s). With Thoughtbop, cycles ultimates every 15-18s in sub-20s rotations.

Core Passive

Cat's Gaze: 1 hit stun buildup (3 hits to break), 12s duration, 1s internal cooldown. Scales 300% ATK (Attackers) or 480% ATK (Anomaly).

Core Skill maxed: +75 Base ATK, +21% Percent ATK. Requires 9 Clouded Crystalline Substance, 60 Bloodstained Miasma Feather, 405,000 Denny.

Total skill investment (1-12): 500,000 Denny, 5 Basic Physical Chips, 15 Advanced, 50 Specialized, 1 Hamster Cage Pass.

Energy Management

Critical breakpoint: 140% Energy Regen enables 15-18s ultimate cycles with Thoughtbop.

Optimal rotation:

1. 0.0s: EX Special (activate Ether Veil)
2. 3.5s: Second EX Special
3. 6.0s: Third EX Special
4. 8.0s: Ultimate (peak damage window)
5. Swap to main DPS during buffs
6. Return when ultimate ready

Meta Role: Strengths & Limitations

Classification

Physical Support, Angels of Delusion faction, Size 01 (standard hitbox). 110 Anomaly Mastery suggests hybrid potential, but multipliers favor Attack-scaling comps.

Natural synergy: Billy, Soldier 0, Anby. Limitation: Teams lacking Physical DPS gain minimal value vs universal supports.

Damage Output

Sub-DPS support with 500% ATK Mesmerized crits. Combined with +50 ATK team buff and +30% Stun DMG Multiplier, creates substantial team damage increases.

Shiyu Defense Floor 12 clear times:

• Sunna-Aria-Koleda: 49s

• Aria-Sunna-Nicole: 52s
• Sunna-Billy-Anby: 67s

Top-tier performance, but all comps include ≥1 premium S-Rank DPS. She multiplies existing damage, not creates it independently.

Content Performance

Shiyu Defense: Strongest application. 49s clears with Aria-Koleda show peak potential. +30% Stun DMG synergizes with Koleda/Anby.

Deadly Assault: Inconsistent—Physical-resistant encounters diminish value, Physical-weak stages elevate to top-tier.

Niche vs Universal

Excels in:

• Physical-focused teams
• Stun-oriented comps
• Burst damage windows

Underperforms in:

• Elemental diversity teams
• Sustained damage comps
• Solo carry situations

Binary decision: Strong Physical DPS roster = high value. Other elements = minimal synergy.

Best Team Compositions

Premium Setup

Highest performance: Aria-Sunna-Koleda (49s Shiyu clears). Aria's Ether Anomaly benefits from ATK buffs while covering elemental gaps. Need both? Recharge Zenless Zone Zero master tapes via BitTopup.

Alternatives:

• Aria-Sunna-Nicole: 52s clears, defensive utility
• Ye Shunguang-Sunna-Zhao: Physical synergy
• Soldier 0-Anby-Sunna: Stun damage focus

All require ≥1 S-Rank DPS + complementary coverage.

F2P Teams

Billy as primary Physical DPS: Sunna-Billy-Anby cleared Floor 12 in 67s—18s slower than premium but acceptable.

Options:

• Trigger-Anby-Sunna: Free starters
• Billy-Sunna-Nicole: Damage + defense
• Anby-Sunna-Flex: Stun-focused

Expect 15-30% lower performance vs premium, but viable for most content.

Bangboo & Flex Slots

Prioritize Physical DMG% or Energy generation Bangboo. 140% Energy Regen breakpoint easier with Energy-focused options.

Flex slot roles:

• Shielders (Koleda): Reduce damage
• Healers (Nicole): Sustain
• Secondary DPS (Aria): Max damage
• Stun supports (Anby): Amplify +30% multiplier

Sunna vs Aria: Pull Priority

Aria's Kit

S-Rank Ether Anomaly DPS, Angels of Delusion, Phase 2 (conflicting dates: Feb 27-Mar 20 or Mar 4-Mar 24, 2026). Anomaly archetype focuses on status effects vs traditional Attack scaling.

Complementary roles—teams can use both (49s Sunna-Aria-Koleda clears). But resource-limited players must choose.

Meta Relevance

Aria's DPS role = broader immediate value for weak damage rosters. DPS forms team foundation; supports enhance existing damage.

Content considerations:

• Shiyu Defense: Both perform well; depends on roster gaps
• Deadly Assault: Aria's Ether covers different enemies than Sunna's Physical
• Hollow Zero: DPS clears faster
• Story: DPS enables smoother progression

Audit roster: Lack damage output? Pull Aria. Lack amplification? Pull Sunna.

Long-Term Value

Supports maintain longer meta relevance via multiplicative scaling with future releases. Sunna's buffs benefit every future Physical DPS; Aria faces power creep from subsequent Ether DPS.

But assumes continued Physical development. If future versions prioritize other elements, Sunna's value drops.

Rerun probability: Sunna likely returns before Aria (earlier release). Skip = potential 6-9 month wait.

Team Flexibility

Aria integrates into more archetypes (any Ether/Anomaly comp). Sunna demands Physical teams for optimal value.

Conversely, Sunna doesn't compete for field time with existing DPS. Players with strong Ether DPS gain little from Aria but Sunna enhances current investments.

Mindscape Cinema: Dupe Value

M1 Analysis

15 Energy/180s (Investigation Zones), enemy DEF -7% (40s, stacks 3x to -21% max).

-21% DEF = ~15-20% team damage increase. Strong first constellation for supports. But 28,800 Polychrome worst-case cost post-M0 = substantial commitment.

M2-M6 Breakdown

• M2: Ether Veil +10% ATK, 1 Claw Sharpener/10s, Cat's Gaze DMG +200% ATK (+300% Anomaly)
• M4: Ultimate +18% squad DMG (60s)
• M6: 8s guaranteed CRIT, CRIT DMG +0.03%/initial ATK (max 105%), DMG taken -40%, Cat's Gaze +50% squad DMG

M6 transformative but requires 86,400-172,800 Polychromes worst-case—exceeds multiple S-Ranks.

M0 vs M1

M0 = optimal stop for most. M1 luxury, not essential. Only pursue if:

• All desired S-Ranks secured
• Polychromes >50,000 post-upcoming banners
• Endgame optimization phase
• No W-Engine upgrade needs

F2P/low spenders: Avoid dupes beyond M0. Opportunity cost vs Aria/future characters = negative value.

W-Engine Recommendations

Signature: Thoughtbop

713 base ATK (Lv60), 60% Energy Regen, 0.6 Energy/s off-field. EX Special: 12.5% Physical DMG (stacks 2x to 25%), +10% ATK (40s).

Achieves 140% Energy Regen breakpoint, reduces Drive Disc pressure. Off-field Energy benefits quick-swaps.

Upgrade: 400,000 Denny, 4 Basic Support Components, 32 Reinforced, 30 Specialized.

But separate pity (12,000-28,800 Polychromes). Evaluate vs saving for Aria/future characters.

Alternatives

1. Energy Regen W-Engines: Hit 140% breakpoint, lack Physical DMG bonus
2. ATK-scaling: Amplify Mesmerized damage, need Energy Regen from Drive Discs
3. Hybrid stat: Balance both, lower peak performance

Performance gap: 10-15% vs Thoughtbop in optimal rotations. Narrows with strong Drive Discs.

F2P Options

Prioritize any Energy Regen W-Engine approaching 140% breakpoint. Specific choice matters less than functional Energy economy.

Total build cost: 1,700,000-4,105,000 Denny, 5 Hamster Cage Passes across all systems.

Pull Decision Framework

Account Audit

Physical DPS Check:

• Own Billy, Soldier 0, or Physical dealers?
• Built with proper Drive Discs/W-Engines?
• Actively use Physical teams in endgame?

Support Roster:

• Current support characters?
• Existing ATK buffs/Stun DMG amplification?
• Gaps Sunna specifically addresses?

Elemental Coverage:

• Which elements lack representation?
• Struggle with content due to weaknesses?
• Would Aria's Ether fill more critical gap?

Yes to Physical + no to adequate support = max Sunna value. Opposite = prioritize Aria/future.

Budget Assessment

Calculate capacity:

1. Current Polychromes + pity progress
2. Expected income through Mar 4 (8,000-12,000 F2P)
3. Worst-case Sunna cost (28,800)
4. Remaining for Aria

Total >40,000 = reasonable attempt at both with 50/50 luck. <40,000 = choose one or risk neither.

F2P Recommendations

PULL if:

• Own built Physical DPS
• Polychromes >30,000 with favorable pity
• No interest in Aria
• Physical teams block progression

SKIP if:

• Lack Physical DPS or build plans
• Polychromes <20,000
• Aria addresses critical gaps
• Prefer guaranteed characters over 50/50

Conservative approach: Prioritize Aria (DPS, broader applications), save Sunna for rerun.

Spender Considerations

M0 Sunna + Thoughtbop: ~40,000-60,000 Polychromes average ($200-300 USD). Provides:

• One S-Rank support
• Signature optimization
• Immediate Physical team improvement

Compare to Sunna (M0, alt W-Engine) + Aria (M0) for similar cost. Dual-character = greater flexibility vs individual optimization.

Decision Tree

STRONG PULL:

• Own Billy/Soldier 0 with investment
• Polychromes >35,000
• Enjoy Physical playstyle
• Cleared desired past banners

CONDITIONAL:

• Physical DPS but limited resources (20,000-30,000)
• Uncertain about Aria's final kit
• Willing to skip Aria entirely

SKIP:

• Polychromes <20,000
• No Physical DPS built
• Prefer Aria's DPS role
• Anticipate must-pulls in 2.7+

Resource Planning

2.6 Income Sources

F2P accumulation (8,000-12,000 total):

• Dailies: 60 × 27 days = 1,620
• Shiyu Defense: 300 biweekly × 2 = 600
• Weekly: 420 × 4 = 1,680
• Events: 4,000-6,000 estimated
• Trust: 120 Polychromes + 1 Master Tape

Additional: Achievements, exploration, maintenance compensation.

Pity Strategy

Approaching soft pity (75 pulls) on Sunna? Options:

1. Complete pity: Secure character, reset to 0
2. Stop pulling: Preserve for Aria
3. Pull to threshold: Build to 60-70 without triggering soft pity

Lost previous 50/50 (guaranteed Sunna)? Complete if desired. On 50/50? Higher risk—consider stopping pre-soft pity.

Emergency Farming

Additional 2,000-5,000 Polychromes from:

• Uncompleted achievements
• Unexplored zones
• Character Trust levels
• Hollow Zero progression
• Incomplete story chapters

One-time sources—won't replenish for future banners.

Common Misconceptions

Myth 1: Every S-Rank is Must-Pull

New character syndrome creates false urgency. Sunna = strong Physical support, but players lacking Physical DPS gain minimal benefit. Supports require established DPS to amplify.

Reality: Sunna's 500% ATK Mesmerized + buffs multiply existing damage, not create independent clearing power.

Myth 2: Signature W-Engines Always Necessary

Thoughtbop optimizes but alternatives achieve 85-90% performance with proper Drive Discs. 12,000-28,800 Polychrome investment often provides lower value than additional characters.

Critical threshold: 140% Energy Regen. Any W-Engine enabling this = functional performance. 10-15% gap rarely determines content completion.

Myth 3: Limited Characters Never Rerun

Established gacha patterns suggest 6-9 month rerun cycles. Skip Sunna = temporary unavailability, not permanent exclusion. FOMO creates pressure conflicting with optimal resource management.

Reruns occur during content lulls. Most limited characters return with advance notice.

Future Banner Roadmap

Aria Timeline

Phase 2: Feb 27-Mar 20 or Mar 4-Mar 24, 2026 (conflicting reports). Earlier date = 6-day overlap with Sunna (ends Mar 4); later = immediate succession.

Duration: 20-24 days. Skip Sunna = accumulate additional 1,200-1,440 Polychromes from dailies + weekly/event income.

2.7+ Rumors

No official announcements. Community speculation suggests reruns, but unconfirmed. Treat predictions as speculative.

Historical patterns: New S-Rank every 3-4 weeks implies 2.7 introduces limited characters ~4-6 weeks post-Aria. Angels of Delusion faction hints at potential third member.

Rerun Predictions

Limited reruns typically 6-9 months post-release. Sunna (Feb 2026) = potential Aug-Nov 2026 rerun, assuming industry-standard patterns.

Reruns coincide with:

• Major version milestones
• Seasonal events
• Content lulls
• Faction-themed events

Skip Sunna = anticipate 6+ month wait (48,000-72,000 F2P income accumulation).

Final Verdict

Strong Pull

Pull confidently if:

• Own built Physical DPS (Billy with gear, Soldier 0)
• Polychromes >30,000 with favorable pity
• Lack strong supports
• Actively use Physical teams in endgame
• No interest in Aria

Immediate, measurable value via team amplification. 49-67s Shiyu clears show ceiling.

Skip

Save resources if:

• No Physical DPS built/planned
• Polychromes <20,000 without guaranteed pity
• Aria addresses critical gaps (Ether/Anomaly coverage)
• Prefer DPS over support playstyles
• Anticipate must-pulls in 2.7+

Conservative approach prioritizes roster breadth and DPS acquisition.

Conditional

20,000-30,000 Polychromes + moderate Physical investment = highest difficulty.

High-risk:

• On 50/50, no pity
• Want both Sunna + Aria
• Limited spending/strict F2P
• Uncertain Physical team viability

Acceptable-risk:

• Approaching soft pity (60+ pulls)
• Won previous 50/50 (guaranteed)
• Willing to skip Aria
• Moderate spending capacity

Borderline = default skip unless Physical teams = primary preference. Opportunity cost of missing both outweighs optimization.

FAQ

How many Polychromes guarantee Sunna?

28,800 worst-case (180 pulls × 160). Accounts for 50/50 loss (90 pulls) + guaranteed hard pity (90 pulls). Average: 12,000-14,400 with 50/50 win at soft pity (75 pulls).

Can Sunna replace meta supports?

Specialized Physical support niche, not universal replacement. Excels in Physical teams (+50 ATK, +30% Stun DMG, 500% ATK crits) but minimal value to non-Physical comps. Evaluate specific team needs vs universal upgrade.

Should F2P skip for Aria?

Most F2P prioritize Aria (DPS role, broader applications). Sunna requires existing Physical DPS; Aria functions as primary dealer. Skip unless actively using Billy/Soldier 0 in endgame with 30,000+ Polychromes.

Does Sunna need Thoughtbop?

Optimizes but not mandatory. Alternatives achieve 85-90% with Energy Regen Drive Discs reaching 140% breakpoint. Prioritize securing Sunna over signature—12,000-28,800 W-Engine cost better invested in additional characters.

When does Aria's banner start?

Conflicting reports: Feb 27-Mar 20 or Mar 4-Mar 24, 2026. Earlier = 6-day overlap with Sunna (ends Mar 4); later = immediate succession. Monitor official announcements.

Best Shiyu Defense teams?

Aria-Sunna-Koleda (49s), Aria-Sunna-Nicole (52s), Billy-Anby-Sunna (67s). All pair Sunna with ≥1 strong DPS + complementary support. F2P: Billy-Anby-Sunna most accessible with competitive clears.
