Complete Kit Analysis: Skills & Mechanics

Sunna's max stats: 7,896 ATK, 5,095 HP, 666 DEF, 110 Anomaly Mastery, 110 Impact. She's a Physical Support with exceptional team buffing via [Mesmerized] and Ether Veil.

[Mesmerized] Mechanic:

• Deals 500% ATK as Physical DMG
• Guaranteed CRIT + 50% CRIT DMG bonus
• No CRIT Rate investment needed—focus ATK and CRIT DMG

Ether Veil:

• +50 ATK team-wide for 30 seconds
• Stacks with other ATK bonuses
• Near-permanent uptime in combat

EX Special (with Thoughtbop):

• 12.5% Physical DMG per stack (max 2 stacks = 25%)
• Lasts 40 seconds
• At 2 stacks: +10% ATK bonus

Energy Generation:

• Thoughtbop: 0.6 Energy/second off-field
• 140% Energy Regen breakpoint = ultimate every 15-18 seconds

Optimal Rotation:

1. Deploy Sunna's EX Special (activate Ether Veil)
2. Swap to main DPS (Sunna generates off-field energy)
3. Return when ultimate ready
4. Reapply [Mesmerized] during damage windows

Meta Evaluation: Tier Placement

Sunna's the premier Physical Support in 2.6. Value scales with Physical DPS roster strength—especially Aria and Ye Shunguang.

Shiyu Defense Performance:

• Consistent team ATK scaling (on/off-field)
• Guaranteed CRIT damage for reliable burst
• 25% Physical DMG amp (with signature W-Engine)
• Faster ultimate rotations via energy support

Physical teams with Sunna achieve competitive Floor 12 clear times, particularly against enemies with Physical vulnerability.

Damage Output: Using The Biggest Fan Bangboo (7,896 ATK, 110 Anomaly Mastery, 50% CRIT Rate, 100% CRIT DMG, 110 Impact):

• [Mesmerized] base: 39,480 damage/proc
• With guaranteed CRIT + 50% CRIT DMG: 78,960 damage/proc

In optimal teams (Aria-Billy-Sunna or Aria-Anby-Sunna): 18-25% team DPS increase vs non-Sunna Physical teams.

Future-Proofing:

• ATK buffing works universally
• Physical DMG amp scales with future Physical DPS releases
• Value increases with each new Physical agent

Skip if you lack Physical DPS—upcoming banners may suit your roster better.

Sunna vs Alternatives: Pull Priority

Sunna excels when:

• Optimizing Physical teams (no other S-Rank matches her Physical support)
• Running ATK-scaling compositions (universal buffs)
• Needing consistent damage (guaranteed CRIT eliminates RNG)
• Supporting energy-hungry teams (off-field generation)

She underperforms when:

• Lacking Physical DPS investment
• Elemental reactions provide better scaling
• Content requires specific elemental coverage

Investment Costs:

• Promotion: 800,000 Denny, 4 Basic Support Seals, 32 Advanced Support Seals, 30 Ruler Support Seals
• Skills: 500,000 Denny, 5 Basic Physical Chips, 15 Advanced Physical Chips, 50 Specialized Physical Chips, 1 Hamster Cage Pass
• Thoughtbop upgrades: 400,000 Denny, 4 Basic Support Components, 32 Reinforced Support Components, 30 Specialized Support Components
• Total Denny: 1,700,000

Moderate investment vs main DPS. Most value at base M0.

Optimal Team Compositions

Premium: Aria-Billy-Sunna

• Aria: Main Physical DPS (benefits from ATK buffs + Physical DMG amp)
• Billy: Secondary DPS (fills Aria downtime)
• Sunna: Support (Ether Veil + [Mesmerized] burst)

Max Physical output with consistent buff uptime.

Alternative Premium: Ye Shunguang-Sunna-Zhao Sustained damage focus. Zhao provides defense while Sunna amps Ye Shunguang's Physical output.

F2P: Aria-Anby-Sunna

• Aria: Obtainable via standard banner/events
• Anby: Free starter (Electric support)
• Sunna: Only limited S-Rank needed

Anby stuns create damage windows for Aria burst. Sunna maintains ATK buffs. Achievable for F2P saving specifically for this banner.

Bangboo: The Biggest Fan Perfect synergy: 7,896 ATK, 110 Anomaly Mastery, 50% CRIT Rate, 100% CRIT DMG. ATK scales [Mesmerized]; CRIT stats boost team damage.

Build Guide: W-Engines, Drive Discs & Stats

Priority: 140% Energy Regen breakpoint for consistent ultimate uptime. Then ATK for [Mesmerized] scaling, Physical DMG for team amp.

W-Engine Rankings:

1. Thoughtbop (Signature S-Rank)

• 713 base ATK (Lv60)
• 60% Energy Regen
• 0.6 Energy/sec off-field
• 12.5% Physical DMG/stack (max 25%)
• 10% ATK at 2 stacks

Unmatched synergy—meets Energy Regen needs while amping Physical damage.

2. Weeping Cradle (Alternative S-Rank)

• 684 base ATK
• 24% PEN Ratio
• 0.6 Energy Regen/sec off-field

Comparable energy generation with penetration. Lacks Thoughtbop's Physical DMG amp but works if you already own it.

3-5. A-Rank Energy Regen Options Budget alternatives reach 140% breakpoint via W-Engine + Drive Disc combos. Sacrifice damage amp for accessibility.

Drive Disc: Swing Jazz 4-piece

• 2pc: +20% Energy Regen
• 4pc: +15% Chain/Ultimate squad DMG (12 sec)

Addresses Energy Regen + amps team damage during ultimates. 12-sec buff aligns with rotation timings.

Main Stats:

• Slot 4: ATK% (scales [Mesmerized])
• Slot 5: Physical DMG% (amps team Physical output)
• Slot 6: Energy Regen (reach 140%)

Substat Priority:

1. Energy Regen (until 140%)
2. ATK%
3. CRIT DMG (benefits guaranteed CRIT)
4. CRIT Rate (lower priority)

Stat Breakpoints:

• 140% Energy Regen: critical threshold for consistent ultimate availability. Exceeding provides minimal value—stop here.
• ATK: linear returns until 8,000+ (no diminishing returns)
• CRIT DMG: consistent value with guaranteed CRIT mechanic

Constellation Value: Pull Duplicates?

Sunna's Mindscape Cinema offers incremental improvements, not transformative spikes. Optimal value at M0 for most players.

M1: +15 Energy every 180 sec; -7% enemy DEF for 40 sec (stacks 3x max)

• 21% max DEF reduction = ~8-12% team damage increase

M2: +10% ATK in Ether Veil; Cat's Gaze DMG +200% (Attack builds) or +300% (Anomaly builds)

• Moderate value for hybrid damage builds

M4: Ultimate grants +18% squad DMG for 60 sec

• Highest-value constellation for team builds. 60-sec duration covers 3-4 rotation cycles.

M6: Focused Creation: 8 sec guaranteed CRIT with CRIT DMG +0.03%/point initial ATK (max 105%)

• At 7,896 ATK: ~237% additional CRIT DMG during 8-sec window
• Whale-tier investment with diminishing returns

Stopping Points:

• F2P/Low Spenders: M0. Constellations offer minimal value vs saving for future characters.
• Monthly Pass: M1 reasonable if long-term investment, but M0 recommended for roster diversity.
• Whales: M4 optimal (team damage amp without M6's extreme cost). M6 only for dedicated showcase accounts.

Pull Decision Framework

F2P Income: 8,000-10,000 Polychromes/month. Guaranteeing Sunna = 2.5-3 months income.

Pull if:

• You main Physical DPS (Aria, Ye Shunguang)
• Roster lacks S-Rank supports
• 30,000+ Polychromes saved with no immediate priorities
• Version 2.7 leaks don't address critical roster gaps

Skip if:

• Lacking Physical DPS investment
• Below 20,000 Polychromes without guarantee
• Upcoming banners fill more critical roles
• Prioritizing favorite characters over meta

Light Spenders (Monthly Pass): 12,000-15,000 Polychromes/month. More flexibility for targeted pulls. Prioritize character over W-Engine—Sunna works with A-Rank Energy Regen W-Engines. Thoughtbop provides incremental, not transformative, improvements.

For efficient management, top up zenless zone zero master tapes through BitTopup for competitive rates and instant delivery.

Conservative Strategy: Maintain 14,400 Polychromes (90 pulls) reserve after pulling Sunna for future 50/50 attempts.

Aggressive Strategy: Commit full reserves if comfortable with longer saving periods.

Final Verdict: Is Sunna Worth It?

Sunna's a specialized but powerful investment for Physical team compositions. Unique support, guaranteed CRIT mechanics, and team ATK buffing provide substantial value with appropriate DPS pairings.

Definite Pull:

• Physical DPS mains (Aria, Ye Shunguang)
• Lacking S-Rank supports
• 28,800+ Polychromes with no immediate priorities
• Angels of Delusion collectors

Conditional Pull:

• 14,400-28,000 Polychromes willing to risk 50/50
• Planning future Physical DPS acquisitions
• Light spenders comfortable with monthly pass supplementation

Skip:

• F2P below 20,000 Polychromes without Physical DPS
• Prioritizing upcoming leaked characters
• Satisfied with current support roster
• Preferring elemental reaction teams

Highest Priority When:

1. Primary DPS is Physical (Aria/Ye Shunguang invested)
2. Support roster lacks S-Rank options
3. 25,000+ Polychromes with guarantee
4. No upcoming characters address critical gaps
5. Shiyu Defense needs Physical optimization

Meeting 3+ criteria = Sunna pull value exceeds opportunity cost.

Skip if Version 2.7 features:

• New elemental DPS matching invested supports
• Universal supports with broader flexibility
• Favorite characters over meta
• Limited reruns of missed high-value characters

Meta suggests diversifying element coverage before specializing Physical teams.

FAQ

Is Sunna worth pulling in ZZZ 2.6? Yes for invested Physical DPS players (Aria/Ye Shunguang)—provides 18-25% team damage increase. F2P without Physical DPS should skip unless 28,800+ Polychromes saved with no upcoming priorities.

How many Polychromes to guarantee Sunna? 28,800 Polychromes (180 pulls) accounting for 50/50. Single 50/50 attempt: 14,400 (90 pulls). Most receive S-Ranks at pulls 75-85 during soft pity.

What are Sunna's best teams? Premium: Aria-Billy-Sunna. F2P: Aria-Anby-Sunna. Alternative: Ye Shunguang-Sunna-Zhao. All benefit from The Biggest Fan Bangboo.
