ZZZ 2.6 Banners: Sunna & Aria Guide + Polychrome Tips

Version 2.6 drops two S-Rank Angels of Delusion agents in a 42-day cycle starting February 6, 2026. Sunna's a Physical Support specialist with squad-wide damage buffs and guaranteed crit detonations. Aria's an Ether Anomaly dealer using Light Stick mechanics for sustained attribute damage. F2P players earn 8,000-12,000 Polychromes per patch—you'll need 28,800 for guaranteed pulls. Here's your complete breakdown for smart pull decisions.

Version 2.6 Banner Schedule

Launch: February 6, 2026 at 11:00 AM UTC+8, running through March 25 (42 days total).

Phase 1 (Feb 6-27): Sunna + Song of Thoughts W-Engine
Phase 2 (Feb 27-Mar 25): Aria + Angel in the Shell W-Engine

Both agents share Angels of Delusion faction—first dual-banner featuring faction-exclusive characters.

W-Engine Stats

Song of Thoughts (Sunna): 713 base ATK, 60% Energy Regen, +0.6 Energy/s off-field. EX Special Physical DMG grants squad DMG +12.5% for 40s (stacks 2x, adds +10% ATK at max).

Angel in the Shell (Aria): 713 base ATK, 30% Anomaly Mastery, +90 Anomaly Proficiency, +20% DMG to Attribute Anomaly enemies, +12% Attribute Anomaly DMG for 15s.

The 42-day window lets you delay pulls until final week—wait for community testing results. Daily commissions add 2,520 Polychromes over full duration (60 × 42 days).

Sunna Kit Breakdown

Sunna amplifies squad damage through Mesmerized marks. Allies detonating marks deal 500% ATK as AoE Attribute DMG. Anomaly-based detonations get guaranteed CRIT + 50% CRIT DMG—insane synergy with Anomaly teams despite Physical typing.

Core Mechanics

Mesmerized Mark: 12s duration. Transforms heavy attacks into detonations. Coordinate heavy attacks during uptime for max value.

Fever State: ATK +30% (capped at 1,000 bonus ATK). Applies Ether Veil Idol for Stun DMG Multiplier +30% for 40s. Near-permanent uptime in sustained fights.

Energy Management: Song of Thoughts' +0.6 Energy/s off-field solves her energy hunger. Without it, stack Energy Regen substats or accept longer rotations.

Rotation: Trigger Fever → swap to DPS for Mesmerized detonations → cycle back before buff expires.

Aria Abilities Deep Dive

Aria uses Light Stick charges for multiplicative damage. Scales purely with Anomaly Proficiency—first S-Rank fully committed to Anomaly scaling without ATK dependencies.

Light Stick System

• Every 4th Basic Attack = 1 Light Stick
• Charge Attacks consume sticks: +20 Decibels/stick, +10% DMG/stick (stacks 2x for +20% max), +15% Anomaly Buildup/stick
• EX Special generates 3 sticks instantly + Ether Veil Idol (+50 ATK squad-wide for 30s)

Gameplay Loop: 4 basic attacks → Charge Attack → repeat. Weave EX Specials for instant sticks.

Abloom Scaling

Level 3 Charge Attacks trigger Abloom: 6.2-7.7% Ether Anomaly DMG per 10 Anomaly Proficiency over 20s. At 500 Proficiency, that's 310-385% Ether Anomaly DMG from Abloom alone.

20s duration creates overlapping damage while generating more sticks. Maintain Abloom uptime as primary DPS priority.

Bonus damage against Attribute Anomaly enemies—pair with secondary Anomaly agents for multiplicative scaling.

Sunna vs Aria: Pull Priority

Sunna: Force multiplier for existing DPS. Minimal personal damage—value in enabling teammates. Best for accounts with strong DPS lacking support.

Aria: Self-sufficient Anomaly carry. Direct sustained damage through Abloom + Light Stick Charge Attacks. Best for accounts lacking Anomaly coverage or Ether attribute.

Content Performance

Shiyu Defense: Sunna's squad buffs excel in timed burst windows. Guaranteed CRIT on Anomaly detonations = free stat value.

Hollow Zero: Aria's sustained percentage-based scaling shines against high-HP targets.

Account Stage Recommendations

New (Level 1-30): Pull Aria. Self-sufficient carries accelerate early progression better than supports needing established rosters.

Mid-game (31-50): Evaluate roster gaps. Strong Physical DPS but no support? Sunna. Adequate supports but missing Anomaly? Aria.

Endgame (50+): Pull based on Shiyu Defense dual-team needs. Fill whichever gap exists—support or Anomaly coverage.

Sunna Best Builds

Disc Drives

Slot 4: ATK% > CRIT Rate > CRIT DMG (ATK scales Fever buffs + Mesmerized detonations)
Slot 5: ATK% > PEN > Physical DMG (PEN benefits all damage types including Attribute detonations)
Slot 6: Energy Regen > ATK% (Energy Regen mandatory without signature W-Engine)

W-Engine Priority

Song of Thoughts: Irreplaceable +0.6 Energy/s off-field + squad DMG +25% at max stacks. Directly solves energy issues.

F2P Alternatives: Any W-Engine with Energy Regen stat. Compensate with Energy Regen substats on Disc Drives.

Substat Priority

1. Energy Regen (25-30% total for comfortable rotations)
2. ATK% (scales buffs + detonations)
3. CRIT Rate/DMG (only after Energy + ATK satisfied)
4. PEN (universal team damage)

Aria Optimal Build

Disc Drives

Slot 4: Anomaly Mastery (non-negotiable—scales Abloom + attribute application)
Slot 5: Ether DMG > ATK% > PEN (Ether DMG multiplicative for all Ether instances)
Slot 6: Anomaly Proficiency > ATK% > Energy Regen (Proficiency feeds Abloom's 6.2-7.7%/10 scaling)

W-Engine Tiers

S-Tier: Angel in the Shell (+90 Proficiency, +20% DMG to Attribute Anomaly enemies, +12% Attribute Anomaly DMG)
A-Tier: Anomaly-focused alternatives with Mastery/Proficiency (70-80% signature effectiveness)
B-Tier: ATK-focused options (50-60% effectiveness—Aria scales Anomaly stats too heavily)

Stat Targets

Anomaly Proficiency: Soft cap at 500 for Abloom scaling, but application rates scale linearly—high investment still valuable for multi-target.

Ether DMG: Multiplicative stacking without diminishing returns. Target 40-50% from Slot 5 + substats.

Team Compositions

Sunna Teams

Premium: Ye + Sunna + Shunguang (maximizes Mesmerized detonations through coordinated heavy attacks)
Alternative: Zhao + Sunna + Dialyn (Zhao's heavy attack patterns + Dialyn defensive utility)
F2P: Any Physical DPS + Sunna + Defensive Support (requires heavy attack access)

Aria Teams

Anomaly Stack: Billy + Sunna + Aria (overlapping Anomaly windows, guaranteed CRIT detonations)
Dual-Attribute: Anton + Sunna + Aria (Electric + Ether pressure)
F2P: Nicole + Anby + Aria (Nicole ATK buffs + Ether RES shred, Anby Stun utility, no limited agents needed)

Bangboo Picks

Sunna: Energy Regen or ATK buff Bangboos (Physical DMG types offer minimal value)
Aria: Anomaly Mastery Bangboos directly scale damage. Ether-attribute types add application speed.

Polychrome Income & Planning

F2P earns 8,000-12,000 Polychromes per 42-day patch:

• Daily Commissions: 60/day = 2,520 over 42 days
• Shiyu Defense: 720 bi-weekly = 1,440 monthly (endgame-gated)
• Hollow Zero: 960 over 6 weeks
• Events: 2,000-4,000 per version (varies by complexity)

Pull Costs

• 1 pull = 160 Polychromes
• Hard pity = 90 pulls = 14,400 Polychromes
• Guaranteed featured (accounting for 50/50 loss) = 180 pulls = 28,800 Polychromes
• Soft pity (pulls 75-80) averages 12,000-13,600 Polychromes

Timeline Projections

Patch 2.6: 8,000-12,000 earned. Can't guarantee both agents starting from 0—prioritize one.
Patch 2.7: Skip 2.6 to accumulate 16,000-24,000 (approaching single guarantee).
Patch 2.8: Three-patch savings = 24,000-36,000 (one guarantee + potential second 50/50).

Pity System Mechanics

Hard Pity

Guaranteed S-Rank at pull 90. Pity persists across same banner type (limited character banners share pity; W-Engine separate).

50/50 System: First S-Rank = 50% featured, 50% standard pool. Losing guarantees next S-Rank as featured (180-pull worst case).

Soft Pity

Starts pull 75. S-Rank rate increases from 0.6% base to ~32% by pull 89. Most S-Ranks appear pulls 75-85.

Strategy: If approaching 75 pulls with limited Polychromes, continue through soft pity for improved rates if targeting current featured agent.

Track These

• Current pull count (0-90)
• 50/50 status (guaranteed or 50/50)
• Available Polychromes + Master Tapes
• Projected income through banner end

Pull Decision Framework

New Players

Pull Aria. Self-sufficient Anomaly carry accelerates progression. Skip W-Engine banners entirely—invest all Polychromes in characters until you have two full Shiyu Defense teams.

Mid-Game

Strong Physical DPS with heavy attacks? Pull Sunna.
Adequate supports but missing Anomaly? Pull Aria.

Endgame

Pull based on Shiyu Defense dual-team gaps. Consider W-Engine banners only if character roster complete (15-25% performance gain).

Skip If

• Current roster handles all content
• Future leaked banners feature higher-priority agents
• Polychromes below 14,400 (insufficient acquisition chance)
• Neither fills critical roster gap

Maintain daily commissions even when skipping for passive accumulation.

Common Mistakes

Polychrome Errors

❌ Spending on standard banner (no rate-up mechanics)
❌ Pulling W-Engines before complete character roster
❌ Continuing pulls after winning 50/50 early without guaranteed pity

Evaluation Misconceptions

❌ S-Rank always beats A-Rank (certain A-Ranks match S-Rank in specific roles)
❌ Signature W-Engines mandatory (both function with F2P alternatives)
❌ Newer = automatic powercreep (2.6 agents fill niches, don't universally replace)

Team Building Oversights

❌ Building around single agents without synergy consideration
❌ Neglecting Bangboo selection (10-15% performance impact)
❌ Ignoring attribute coverage (Shiyu Defense elemental weaknesses reward diversity)

FAQ

When do ZZZ 2.6 banners release?
February 6, 2026 at 11:00 AM UTC+8. Phase 1 (Sunna) runs Feb 6-27; Phase 2 (Aria) runs Feb 27-Mar 25.

How many polychromes for guaranteed character?
28,800 maximum (180 pulls accounting for 50/50 loss). Most acquire between 12,000-13,600 due to soft pity at pull 75.

Sunna or Aria better for F2P?
Aria. Self-sufficient carry needing minimal team investment. Sunna requires established DPS teammates to maximize buffs.

Best Aria teams?
Billy + Sunna + Aria (Anomaly stacking), Anton + Sunna + Aria (dual-attribute), Nicole + Anby + Aria (F2P, no limited agents).

Pull Sunna's signature W-Engine?
Only after securing Sunna and if reserves exceed 14,400 for future guarantees. Significant Energy Regen + squad buffs but not mandatory. F2P prioritize characters over weapons.

How does soft pity work?
Starts pull 75, increasing S-Rank rate from 0.6% to ~32% by pull 89. Most acquire S-Ranks pulls 75-85, not hard pity at 90.
