Sunna, the S-Rank Physical Support released February 6, 2026 in Version 2.6, revolutionizes team building through unique Quick Assist mechanics and Angels of Delusion synergy. This guide covers optimal Attack/Anomaly pairings, frame-perfect rotations, and energy management for endgame content. Whether building around Aria for Anomaly teams or Soldier 0/Anby for Attack comps, mastering Sunna's 60% Energy Regen mechanics and Cat's Gaze buff system unlocks full potential in Shiyu Defense and Deadly Assault.
Understanding Sunna's Role in 2.6 Meta
Sunna functions as Physical Support within Angels of Delusion faction, delivering squad buffs while generating energy off-field. Her kit centers on rapid EX Special deployment triggering Cat's Gaze—a damage amp dealing 300% ATK (Attackers) or 480% ATK (Anomaly agents). This guaranteed CRIT mechanic with 1-second internal cooldown makes her versatile across team archetypes.
Core distinction: Quick Assist activation system. After Assist Follow-Up, she generates zero Assist Points, allowing immediate re-entry without cooldowns. This enables 8-second rotation cycles where Sunna deploys EX Specials at 0.0s, 3.5s, and 6.0s while teammates execute damage windows between.

Combat Mechanics & Unique Systems
Sunna's kit revolves around three energy-dependent abilities:
Bubblegum Barrage (70 Energy Special)
Photography Technique (0 Energy)
Ultimate (variable cost)
Angelic Chord-ination passive grants 15 Energy on battlefield entry, with max buff effectiveness at 3500 ATK. This threshold determines optimal Drive Disc/W-Engine stat distribution.
Cat's Gaze trigger conditions: 1 hit during stun vs 3 hits outside stun. Effect expires after 12 seconds if not refreshed. With Anomaly agents, the 480% ATK multiplier transforms into primary damage source rather than supplementary buff.
Special Attack provides 12% Anomaly Buildup per stack (max 3 stacks). This makes her effective in Disorder comps despite Physical Support classification, especially with Aria who benefits from both Anomaly Buildup and guaranteed CRIT instances.
Angels of Delusion Faction Synergy
Faction synergy activates with multiple faction members, providing combat advantages. Sunna's release alongside Aria and Nangong Yu creates natural team cores maximizing faction bonuses while maintaining optimal rotations.
Off-field energy generation: 0.6/second (with Thoughtbop W-Engine) allows teammates to maintain Ultimate availability without sacrificing field time. This stacks with active combat gains, enabling 8-second scripts where both Sunna and primary DPS execute Ultimates within same cycle.
60% Energy Regen baseline from Thoughtbop + Slot 6 Energy Regen Drive Disc (15-20% additional) = 75-80% total. This ensures EX Special availability every 3.5 seconds—exact timing for optimal Quick Assist chains preventing damage gaps.
Key Stats & Multipliers
Stat Priority:
ATK% on Partition 4/5 Drive Discs
Energy Regen on Partition 6
Substats: ATK%, Flat ATK, CRIT RATE, CRIT DMG, Anomaly Proficiency
Mindscape Breakpoints:
M1: 15 Energy on entry + 21% DEF Shred during Cat's Gaze
M2: 10% ATK to squad + 1 Claw Sharpener/10s + Cat's Gaze multipliers to 200% (Attackers)/300% (Anomaly)
M4: 18% DMG to squad for 60s after Ultimate
M6: 100% CRIT RATE for 8s + 105% CRIT DMG (0.03% per ATK) + 50% DMG to Cat's Gaze
Attack Agent Pairings: Best Synergies
Attack comps leverage Sunna's DEF Shred and ATK buffs for burst damage. Optimal structure: Sunna + Primary Attacker + Stunner/Support. Soldier 0, Anby, and Trigger form documented meta composition.
Energy management critical—Attackers generate lower energy than Anomaly agents, making Sunna's 0.6/s off-field generation essential. 70 Energy cost for Bubblegum Barrage = ~117s passive generation alone, but active combat reduces to 10-15s with proper rotations.
300% ATK Cat's Gaze for Attackers (vs 480% Anomaly) triggers more frequently due to higher hit-rate abilities. With M2's 200% boost, rivals Anomaly pairing damage in shorter windows.
Sunna + Soldier 0 + Anby: Physical Core
Most accessible Attack team using Soldier 0 (primary DPS) with Anby (stun/Physical shred).
Rotation Script:
0.0s - Sunna EX Special
0.5-2.0s - Anby stun setup
2.0-3.0s - Soldier 0 burst during stun
3.5s - Sunna EX Special (Quick Assist)
4.0-5.5s - Soldier 0 continued assault
6.0s - Sunna EX Special
6.5-7.0s - Anby Ultimate/Special
7.5s - Soldier 0 Ultimate
8.0s - Sunna Ultimate
Repeat
Trigger substitutes for Anby in non-stun encounters, providing ATK buffs stacking multiplicatively with Sunna's bonuses. Effective against bosses with short vulnerability phases.
Attack Pairing Energy Dynamics
Attack comps generate 40-50 energy/rotation through combined actions. Sunna's 15 Energy on entry (30 with M1) accelerates rotations. Photography Technique's 0 Energy cost allows flexible positioning without sacrificing economy.
Decibel generation: 25-30/rotation, requiring 3-4 cycles for 3000 Chain Attack threshold. Optimal teams use Chain Attacks during Sunna's Ultimate buff window (M4's 18% DMG for 60s), stacking multiplicative bonuses.
60-80% Energy Regen target ensures EX Special availability every 3.5s. With Thoughtbop's 60% + Slot 6 (15-20%), threshold achievable without sacrificing ATK% on Partitions 4/5. Prioritize Flat ATK/ATK% substats once hitting 75%.
Anomaly Agent Pairings: Disorder & DoT
Anomaly comps transform Sunna into secondary damage dealer via 480% ATK Cat's Gaze. Aria = premier pairing within Angels of Delusion, creating faction synergy and complementary timing. Rotation shifts from burst windows to sustained Anomaly cycles.
Guaranteed CRIT on Cat's Gaze eliminates CRIT RATE requirements for this damage instance, letting Anomaly agents focus entirely on Anomaly Proficiency/Elemental Mastery. Stat optimization creates efficiency where traditional builds sacrifice CRIT stats, but Sunna adds guaranteed CRIT damage without investment trade-offs.
Disorder mechanics (second Anomaly type on afflicted enemies) gain amplification through Sunna's 12% Anomaly Buildup per Special stack. At max 3 stacks = 36% faster application, reducing time between Disorder triggers.
Sunna + Aria: Angels Meta Core
Aria's Ether Anomaly synergizes perfectly with Sunna's buff timing.
Rotation Script:
0.0s - Sunna EX Special
0.5-3.5s - Aria Basic Attack
3.5s - Sunna EX Special
4.0-5.0s - Aria Special
6.0s - Sunna EX Special
6.5-7.5s - Aria Ultimate
8.0s - Sunna Ultimate
Repeat
480% ATK multiplier transforms each proc into significant damage. With Sunna's ATK at 3500+, each Cat's Gaze = 16,800 damage before defense. Across 8s rotation with 6-8 triggers = 100,000+ supplementary damage beyond Aria's Anomaly DoT.
Faction synergy activates Angels of Delusion bonuses. Three-agent faction teams maximize benefits—Nangong Yu optimal third slot when available.
Anomaly Rotation Mechanics
Anomaly rotations prioritize sustained field time for primary Anomaly agents vs quick-swap bursts. Sunna's Quick Assist enables 0.5s entry/exit windows, minimizing interruption to Anomaly sequences. Creates weaving where Sunna punctuates chains without disrupting buildup.
Energy generation in Anomaly teams exceeds Attack comps by 15-20% due to higher hit-count abilities. Surplus allows flexible Ultimate timing—holding for boss phases viable without rotation desync. 8s script optimal, but 10-12s variations maintain effectiveness.
1s internal cooldown on Cat's Gaze requires precise hit spacing. Aria's Basic chain naturally spaces hits beyond 1s, ensuring max trigger frequency. Faster-hitting Anomaly agents may waste triggers—attack speed buffs occasionally counterproductive.
When to Choose Anomaly Over Attack
Anomaly excels:
Sustained combat >60s
Disorder stacking/DoT accumulation
Shiyu Defense Floor 12 (2+ min clears)
High Physical resistance enemies
Attack excels:
Speed clears <45s
Burst damage windows
Physical-weak enemies
Time-attack events
Investment differs: Anomaly needs 120+ Anomaly Proficiency + specific W-Engines. Attack demands CRIT RATE/CRIT DMG optimization. Assess existing roster before committing.
Complete Team Compositions
Optimal three-agent teams: Sunna (Support/Buffer) + Primary DPS (Attack/Anomaly) + Flex (Stunner/Support/Sub-DPS). Flex adapts to content—Stunners for stun-vulnerable bosses, Supports for survival, Sub-DPS for damage races.
Documented meta teams:
Ye Shunguang/Sunna/Zhao
Ye Shunguang/Sunna/Dialyn
Faction bonus activation requires careful construction. Full Angels teams (Sunna/Aria/Nangong Yu) maximize faction benefits but restrict flexibility. Hybrid teams sacrifice bonuses for superior synergy—trade-off varies by content difficulty.
Premium: Sunna + Aria + Nangong Yu
Angels of Delusion core = highest Anomaly potential. Aria (primary DPS), Sunna (buffs/secondary damage), Nangong Yu (flex with faction synergy). Full faction activates max bonuses.
Rotation maintains Aria's field time >60%. Sunna's Quick Assist entries during Aria's cooldowns utilize downtime. Nangong Yu's role depends on kit—Stunner setups windows for Aria's Special/Ultimate; Support layers buffs during Sunna's EX Special windows.
Investment Priority:
Aria (primary DPS) - max Anomaly Proficiency + signature W-Engine
Sunna (force multiplier) - functions at M0 with Thoughtbop, M2/M4 significant boosts
Nangong Yu (flex) - Stunners need less than Sub-DPS configs
F2P: Sunna + Soldier 0 + Anby
F2P viable using Soldier 0 (A-Rank Attacker) + Anby (A-Rank Stunner). Zero limited pulls beyond Sunna—most accessible meta team.
Anby's stun windows create damage amp phases where Soldier 0's burst gains max effectiveness. Sunna's Cat's Gaze during stuns benefits from stun bonuses, stacking multiplicatively with DEF Shred (21% at M1). Standard 8s script with Anby initiating stuns at 0.5-2.0s.
Drive Discs achievable through standard farming. Sunna uses 4-Pc Moonlight Lullaby + 2-Pc Swing Jazz (Hollow Zero runs). Soldier 0/Anby use standard sets with ATK%/CRIT RATE/CRIT DMG priorities.
Hybrid: Mixing Factions
Non-faction teams sacrifice Angels bonuses for superior synergies. Sunna's universal buffs make her viable in any comp needing Physical Support.
Example: Sunna + Ellen + Caesar. Ellen (Ice Attacker) benefits from ATK buffs/DEF Shred despite elemental mismatch. Caesar (Support) provides shields + buffs stacking with Sunna's kit. Sacrifices faction bonuses but gains Caesar's defensive utility + Ellen's higher DPS ceiling.
Decision matrix: If faction bonuses <15% total damage increase, hybrid teams with 20%+ synergy advantages mathematically superior. Calculate specific bonuses vs defaulting to faction teams.
Quick-Assist Rotation Scripts
Quick Assist activates when Sunna performs Assist Follow-Up, generating zero Assist Points for immediate re-entry. Differs from standard Assist systems with cooldowns. Understanding this separates functional from optimized comps.
8s rotation = mathematical optimization of Sunna's 3.5s EX Special availability + teammate cooldowns. Deviating creates gaps where buffs expire before refresh or energy stalls. Frame-perfect execution not required for casual content, but Shiyu Floor 12/Deadly Assault demand precise timing.
Scripts adapt by teammate. Aria rotations differ from Soldier 0 due to ability duration/cooldown variations. Core principle constant: Sunna EX Special every 3.5s, teammate abilities filling intervals, synchronized Ultimates at 8s marks.
Advanced Quick-Swap for Speed Clears
Speed-clear rotations compress 8s script into 6-7s by overlapping animations and cancels. Requires precise input timing but reduces clear times 15-20%.
Compression front-loads damage by executing Ultimates at 5.5-6.5s vs 7.5-8.0s, sacrificing final Sunna EX Special. Works when enemies die before second rotation—missed EX Special irrelevant.
Animation canceling: input next command during recovery frames, reducing animation time 0.2-0.3s/cancel. Across 8-10 abilities = 2-3s saved total. Becomes muscle memory after 20-30 reps.
Energy Threshold Management
Maintaining consistency requires tracking thresholds. Sunna needs 70 Energy for Bubblegum Barrage: 15 Energy entry + 0.6/s passive + active gains. Across 3.5s interval = ~17 Energy passively, requiring 53 from combat.
Teammates generate via Basic Attacks (3-5), Specials (8-12), taking damage (variable). Full 8s rotation = 80-100 total Energy for Sunna, providing surplus for Ultimate (60-80 cost) without disrupting EX Special availability.
Energy Regen scaling: diminishing returns beyond 80%. 60-80% target = optimal efficiency where additional regen provides minimal rotation speed while sacrificing ATK% for Cat's Gaze damage. Avoid exceeding 85% unless specific Mindscape configs require higher.
Decibel & Energy Optimization
Decibel Rating accumulates through combat, reaching 3000 for Chain Attacks. Sunna teams generate varying rates—Attack 25-30/rotation, Anomaly 30-35 (higher hit counts). Understanding rates enables strategic Chain Attack timing.
Chain Attack Priority: Primary DPS > Sunna > Flex Support
Execute during Sunna's buff windows (M4's 18% DMG) for max damage. Holding for boss vulnerability phases often outweighs immediate usage.
Ultimate timing creates decision points. Immediate usage maintains consistency but may waste potential outside vulnerability windows. Holding 4-8s delays rotations but can double effective damage with proper timing. Content familiarity determines strategy.
Decibel Generation by Agent Type
Attackers: 8-12/Special, 2-3/Basic hit
Anomaly: 10-15/Special, 3-4/Basic hit
Stunners: 12-18/stun (Anby), varies by kit
Sunna: 10/EX Special
Across 8s rotation with three EX Specials, Sunna contributes 30 Decibels—30-35% of 3000 Chain Attack requirement. Consistent generation makes her reliable Decibel engine.
Optimizing involves maximizing hit counts. Multi-hit abilities generate more Decibels than single-hit high-damage attacks—lower-damage multi-hit Specials sometimes outperform for Decibel economy.
Ultimate Timing: Hold vs Burst
Immediate (8.0s marks): Maintains perfect consistency, prevents energy overcapping. Best for fights without distinct vulnerability phases.
Delayed (4-12s beyond availability): Syncs with boss windows/buff stacks. Risks energy waste but can increase effective damage 50-100% with optimal timing. Deadly Assault scoring rewards this.
Decision matrix: If delaying wastes 20 Energy (~3s generation) but increases Ultimate damage 60% through better timing = net positive. Calculate scenarios vs defaulting universally.
Chain Attack Availability
3000 Decibel accumulation = 3-4 rotation cycles (24-32s) for optimized teams. Strategic usage during M4 buff window (18% DMG for 60s post-Ultimate) creates multiplicative scaling outperforming random timing.
Coordinating with teammate Ultimates stacks bonuses. Example: Sunna Ultimate (8.0s) → Aria Ultimate (8.5s) → Chain Attack (9.0s) layers buffs into 1s window. Burst stacking = highest damage potential.
Avoid premature Chain Attacks. Visual/audio cues create pressure for immediate use, but optimal play often demands 5-10s wait for setup. Practice delayed usage in low-stakes content.
Angels of Delusion Content
Faction content includes specialized encounters where bonuses provide significant advantages. Sunna teams gain max value here, making faction-focused building worthwhile despite synergy sacrifices.
Shiyu Defense Floor 12 = primary endgame where Sunna shows full potential. DPS checks, resistance profiles, time limits demand optimized rotations and construction. Flexibility across Attack/Anomaly enables adaptation to rotating Floor 12 lineups.
Hollow Zero benefits from sustained energy generation and buff uptime. Extended 3-5 min encounters favor Anomaly comps where Disorder stacking accumulates massive damage. Bangboo selection: prioritize energy generation or Anomaly Proficiency bonuses.
Shiyu Defense Floor 12 Adjustments
Current Floor 12 (Version 2.6) features varying resistance profiles. Physical-resistant encounters require pivoting to Aria Anomaly despite Sunna's Physical classification. Universal buffs maintain effectiveness regardless of damage type.
Time optimization targets 90s completion/side (180s total both chambers). Allows 11-12 full cycles within 90s, providing multiple burst windows for boss phases.
Team positioning matters in multi-enemy encounters. Sunna's EX Special has specific range/targeting—understanding prevents wasted activations. Practice target switching during Quick Assist windows.
Deadly Assault Scoring
Scoring rewards damage concentration and time efficiency. Sunna teams excel through burst stacking—concentrating buffs/Ultimates into narrow windows maximizing score multipliers. Algorithm heavily weights peak damage over sustained output.
Optimal strategy delays all Ultimates until 15-20s, allowing full energy accumulation and buff stacking. Burst window: Sunna Ultimate → Primary DPS Ultimate → Chain Attack → Sunna EX Special spam during remaining buff duration. This 8-10s window = 60-70% total score.
M6 Sunna transforms performance via 100% CRIT RATE for 8s buff. Aligns perfectly with burst stacking, guaranteeing CRIT on all abilities during critical scoring phase. Structure entire rotations around this window for max score.
Common Mistakes to Avoid
Overvaluing faction bonuses: Forcing suboptimal agents for faction completion sacrifices 20-30% damage from superior synergies for 10-15% bonuses. Calculate actual values vs assuming faction always outperforms.
Ignoring energy generation: Insufficient Energy Regen (<60% on Sunna) creates gaps where EX Specials aren't available at 3.5s intervals, breaking timing and reducing buff uptime.
Misunderstanding Quick Assist: Executing standard Assist Follow-Ups vs Quick Assists introduces unnecessary cooldowns. Quick Assist activates after Assist Follow-Up completion—must complete full animation before zero-cooldown benefit applies.
Suboptimal Ultimate Usage
Random timing: Wastes 30-50% effective damage. Ultimates = highest-value abilities deserving strategic planning, not reflexive use.
Excessive holding: Delaying for perfect moments often means never finding them, reducing total usage. Optimal strategy uses Ultimates 80-90% of max possible times.
Failing to coordinate: Staggering team Ultimates across 30-40s wastes overlapping buff potential. Compressed usage within 8-10s windows maximizes damage through buff stacking.
Investment Priority & Resources
Resource allocation determines effectiveness more than agent selection. Fully-invested A-Rank team outperforms poorly-invested S-Rank comp.
Primary DPS first priority: Aria for Anomaly, Soldier 0/Attackers for Attack comps. Max level, skill upgrades, optimal W-Engines, complete Drive Discs. Sunna functions as force multiplier—her buffs scale with primary DPS investment.
Sunna moderate investment: Level 50+, Core Passive maxed, EX Special level 8+, Basic Attack 6+, Ultimate 6+. Costs ~800,000 Denny, 4 Basic Support Certification Seals, 32 Advanced, 30 Ruler, plus Chip materials (5 Basic Physical, 15 Advanced, 50 Specialized).
Build Order
Anomaly Teams (Sunna + Aria):
Aria - max level, signature W-Engine, complete Drive Discs with optimal main stats
Sunna - Level 50, Thoughtbop, 4-Pc Moonlight Lullaby + 2-Pc Swing Jazz
Flex Support - Level 40-50, functional W-Engine, basic Drive Disc coverage
Attack Teams (Sunna + Soldier 0):
Primary Attacker - max level, best W-Engine, optimized CRIT ratio
Sunna - Level 50, Thoughtbop, proper sets
Stunner - Level 40-50, Energy Regen focused, basic completion
Ensures max return on limited resources. Fully investing Sunna before primary DPS = well-buffed weak dealer, mathematically inferior to moderately-buffed strong dealer.
Mindscape Breakpoints
M0: Functions effectively in all comps—accessible for F2P. Baseline kit provides sufficient buffs/energy generation for meta-viable performance.
M1: First significant breakpoint. 15 Energy on entry + 21% DEF Shred accelerates rotations, amplifies team damage 18-22%. Highest value-per-pull ratio—recommended stopping point for budget players.
M2 + M4: Second breakpoint tier. M2's 10% ATK + enhanced Cat's Gaze (200% Attackers, 300% Anomaly) increases team damage 15-18%. M4's 18% DMG for 60s post-Ultimate adds 12-15%. Combined transforms Sunna from good to premium.
M6: Luxury investment. 100% CRIT RATE for 8s + 105% CRIT DMG (scaling with ATK) primarily benefits personal damage. Increases total team damage 8-12%—significant but lower value than earlier Mindscapes.
W-Engine Rankings
Sunna:
Thoughtbop - 60% Energy Regen, 0.6 energy/s off-field, 25% DMG Bonus squad, 10% Combat ATK squad (BiS)
Weeping Cradle - 24% PEN Ratio, 0.6 Energy Regen off-field, 20.2% DMG Bonus squad
Kaboom the Cannon - 50% Energy Regen, 16% Combat ATK (budget)
Unfettered Game Ball - 50% Energy Regen, 20% CRIT RATE squad (situational)
Thoughtbop's 60% Energy Regen + off-field generation + dual squad buffs = irreplaceable. Enables 75-80% total target with minimal Drive Disc substat requirements.
Primary DPS: Signature W-Engines provide 25-35% personal damage = 20-28% total team damage. Higher-value than Sunna M2+ for players choosing between options. Secure primary DPS signatures before pursuing Sunna Mindscapes.

FAQ
Can Sunna work without premium S-Rank teammates?
Yes. F2P comp (Sunna + Soldier 0 + Anby) clears Shiyu Floor 12 with proper investment and execution. Buffs scale with teammate quality, but baseline kit provides sufficient value in budget teams. 8s rotation works identically regardless of rarity—mechanical execution more important than roster premium status.
Who are the best Attack agents to pair with Sunna?
Soldier 0 = most accessible (A-Rank, guaranteed acquisition). For premium options, any Physical/Elemental Attacker benefits from universal buffs—Physical Support classification doesn't restrict to Physical dealers. Documented Soldier 0 + Anby + Trigger shows meta-viable Attack construction without limited S-Ranks.
Which Anomaly characters work best?
Aria = premier pairing through Angels faction synergy and 480% ATK Cat's Gaze for Anomaly agents. Documented rotation provides frame-perfect timing for max Anomaly application and Disorder triggers. Alternative Anomaly agents work but sacrifice faction bonuses and optimized timing.
How does quick-assist rotation work?
Quick Assist activates after Sunna completes Assist Follow-Up, generating zero Assist Points for immediate re-entry without cooldowns. Allows 3.5s cycling where Sunna enters, deploys EX Special, exits within 0.5s windows. 8s script schedules Sunna EX Specials at 0.0s, 3.5s, 6.0s while teammates execute between.
What's the optimal rotation script?
Base 8s: Sunna EX Special (0.0s) → Teammate abilities (0.5-3.5s) → Sunna EX Special (3.5s) → Teammate abilities (4.0-6.0s) → Sunna EX Special (6.0s) → Teammate Ultimate (6.5-7.5s) → Sunna Ultimate (8.0s) → Repeat. Specific abilities vary by comp, but 3.5s Sunna timing constant across variations.
Is Sunna better with Attack or Anomaly teammates?
Anomaly gains higher value from 480% ATK Cat's Gaze vs 300% for Attackers, plus benefits from 12% Anomaly Buildup. But Attack excels in burst scenarios <60s. Content determines optimal pairing—Anomaly for sustained fights (Shiyu Floor 12, extended bosses), Attack for speed clears (Deadly Assault, time-attacks). Roster availability and investment often matter more than theoretical optimization.
