Team Compositions

Top Sunna Teams

Sunna + Aria + Physical Stunner

• Dual-carry configuration
• Stunners: Koleda (Fire) or Lycaon (Physical shred)
• Best for multi-phase Shiyu Defense

Sunna + Billy + Anby

• Maximizes Physical damage
• Billy capitalizes on Mesmerized guaranteed CRIT
• Fastest single-target boss clears

Sunna + Anton + Anby (F2P)

• Electric-Physical hybrid
• ~80% premium comp performance

Top Aria Teams

Aria + Sunna + Nicole

• Max Anomaly damage
• Nicole: DEF shred + Ether damage
• Highest sustained DPS

Aria + Billy + Sunna

• Hybrid burst-sustain
• Billy handles Stun phases, Aria maintains pressure

Aria + Anby + Nicole (Budget)

• Anby: Stun setup
• Nicole: DEF shred + Ether amp
• Requires precise rotation timing

Sunna + Aria Synergy

Combined deployment creates 25-30% higher team DPS vs generic supports. Sunna's +50 ATK increases Aria's Basic Attack damage by ~18%. +30% Stun DMG Multiplier enhances Daze window damage.

Rotation: Sunna EX Special → Aria Charge Attack windows (40s buff coverage)

Bangboo Selection

• Butler: Unconditional ATK% (Sunna teams)
• Resonaboo: Anomaly Proficiency (Aria teams, 5-8% damage increase)
• Amillion: Energy Regen + hybrid utility

F2P Builds

Sunna F2P Options

Steam Oven: Requires 25%+ Energy Regen from Drive Disc substats to compensate for 20% performance deficit.

Weeping Gemini: Mid-tier investment, 55.2% Energy Regen reduces substat requirements.

Aria F2P Options

Electro-Lip Gloss: Needs 400+ total Anomaly Proficiency (30+ per disc) for meaningful Abloom scaling.

Rainforest Gourmet: 48 Anomaly Proficiency base reduces farming time.

Farming Timeline

• Complete 4-piece set with acceptable substats: 2-3 weeks focused farming
• Priority: Slot 6 first (Energy Regen/ATK%), then Slot 4 (ATK%/Anomaly Proficiency)

Resource Priority (Low Spenders)

1. Character ascension to 60: 800K Denny + chips (guaranteed returns)
2. Top-priority skills to max (70% resources): Special (Sunna), Charge Attack (Aria)
3. W-Engine to 50 (saves 400K Denny, only 8% stat loss)

Mindscape Investment

Sunna Mindscapes

• M1: +3s Mesmerized duration (12→15s), 25% uptime increase
• M2: Extra Energy Regen, sub-15s Ultimate rotations
• M6: 35% total performance vs M0 (luxury investment)

Aria Mindscapes

• M1: Faster Light Stick generation, 15% rotation speed increase
• M2: Enhanced Buildup Rate + Abloom scaling, 20% damage vs M0
• M6: 40% total performance vs M0

Recommended stops: M0/M1 for Sunna, M1/M2 for Aria (balanced accounts)

Combat Optimization

Sunna Rotation

Standard: EX Special → Stunner Stun → Mesmerized → DPS burst

Energy management: Song of Thoughts generates 8 Energy during 20s DPS windows. Ultimate ready every 18-22s.

Pro tip: Animation-cancel Basic Attack after EX Special (saves 1.5s per rotation).

Aria Rotation

Optimal: 4-hit Basic chain → EX Special (3 Light Sticks) → Charge Attack during Anomaly

Animation cancel: Dodge after 3rd Basic hit, resume chain (saves 0.8s, +8% DPS).

Resource management: Avoid EX Special at 3+ Light Sticks (wasted generation).

Shiyu Defense Floor 30+

Sunna teams: Activate Mesmerized immediately upon Daze. 12s buff covers Stun phase + recovery.

Aria teams: Generate Light Sticks during enemy attacks, execute Charge Attacks during vulnerability windows (3-4 per Anomaly window).

Timing: Activate Sunna EX Special 0.5s before Stun completion for seamless buff application.

Common Mistakes

Sunna Errors

❌ CRIT Rate main stat Slot 4 (Mesmerized guarantees CRIT regardless) ✅ ATK% Slot 4 for better base damage

❌ Physical DMG% Slot 5 for personal damage ✅ ATK% Slot 5 scales both Mesmerized and buffs

❌ Building Sunna as main DPS ✅ Support role maximizes team damage

Aria Errors

❌ Prioritizing CRIT stats over Anomaly Proficiency ✅ 450+ Anomaly Proficiency before CRIT investment

❌ ATK% main stat Slot 4 ✅ Anomaly Proficiency Slot 4 (Charge Attack = 60-70% total damage)

❌ Neglecting Energy Regen substats ✅ Minimum 10% Energy Regen for Ultimate uptime

Team Anti-Synergies

• Don't pair Sunna with non-Physical DPS (wasted Physical DMG buff)
• Aria needs Anomaly support or Stunners (solo application = low DPS)
• Avoid redundant ATK% buffers (additive stacking = diminishing returns)

Character Comparisons

Sunna vs Alternatives

• vs Nicole: Nicole wins Ether teams, Sunna wins Physical
• vs Soukaku: Soukaku peaks higher in Ice teams, Sunna more flexible
• vs Rina: Rina = sustained damage, Sunna = burst windows

Aria vs Alternatives

• vs Jane Doe: Jane higher burst, Aria better sustained (extended fights)
• vs Miyabi: Miyabi higher peak damage, Aria more consistent/accessible
• vs Soldier 11: Soldier 11 faster vs low-DEF, Aria consistent vs all enemy types

When to pull:

• Sunna: Running Physical DPS (Billy/Corin), need guaranteed CRIT support
• Aria: Need Ether DPS, high-DEF content, sustained damage scenarios
• Both: Flexible dual-carry comp covering burst + sustain
