ZZZ 2.6 Event Priority Guide: 1,750 Polychromes & Rewards

Time-Limited vs Permanent Content

Version 2.6 launches February 6, 2026 at 11:00 AM UTC+8. Phase 1 runs February 6 to March 4; Phase 2 extends March 4 to March 23.

Critical distinction: A Harmony of Delusions expires March 23 with 1,590 Polychromes, Pan Yinhu Culinary Jewel outfit, 420,000 Dennies, and 98 Original Chips. No extensions—rewards vanish completely.

Trust progression for Sunna and Aria is permanent after acquisition, but Quality Time requires Friendly Trust Rank first. Daily Trust Invites refresh after server reset (one per agent daily). Trust Events have three in-game days cooldown.

For energy refills during critical windows, Zenless Zone Zero top up through BitTopup ensures sufficient resources.

Event Timeline

• Feb 6: Version 2.6 launch, A Harmony of Delusions begins, Sunna banner starts
• Feb 14-23: Gilded Surprise Wonderful Boo-ns (single daily draw Feb 14-20, triple daily Feb 17-21)
• Feb 17-21: Triple draw window—missing one day costs three rewards
• Mar 4: Phase 2 begins, Aria banner starts
• Mar 23: All time-limited events expire, shops close

Trust System Checklist

Permanent vs Time-Gated

Trust Levels are permanent—progression remains accessible indefinitely after character acquisition. However, daily invites refresh once per day. Missing invites wastes progression opportunities that can't be recovered.

Mechanics:

• Daily invites: One per agent after server reset
• Trust Events: Three-day cooldown
• Dialogue choices: Aligned responses accelerate Trust gain
• Gifts: Cost 1,000-3,000 Dennies; aligned gifts grant 200+ Trust points
• Timeline to Friendly: 2-3 days with optimal invites

Unlock Requirements

Sunna:

1. Complete Encore for an Old Dream Season 2 Interlude
2. Acquire from Phase 1 banner (Feb 6 - Mar 4)
3. Complete initial Trust Missions
4. Access Trust Events: Whimsy in the Triple Meter and Encore for an Old Dream

Aria:

1. Complete prerequisite Phaethon's Story chapters
2. Acquire from Phase 2 banner (Mar 4 - Mar 23)
3. Complete Aria Agent Story chapters
4. Progress initial Trust Missions

Farming Priority

Stop at Level 4 for reward-focused players. Levels 2-4 provide all Polychromes (80 total), 30,000 Dennies, and Dynamic Wallpaper.

Ranking:

1. Level 2: 20 Polychromes, 5,000 Dennies, 3 Advanced Chips—fastest rewards
2. Level 3: 30 Polychromes, 10,000 Dennies—high yield
3. Level 4: 30 Polychromes, 15,000 Dennies, wallpaper—completionist milestone
4. Level 5+: Story content only—lower priority

Common Mistakes

1. Delaying Trust progression: Wastes daily invites that can't be recovered
2. Ignoring dialogue alignment: Slower Trust gain, extra days to Friendly rank
3. Assuming Trust expires with banners: Causes rushed/inefficient progression
4. Neglecting story prerequisites: Locks Trust despite character ownership
5. Forgetting three-day cooldown: Wasted time checking menus

1. Polychromes—absolute priority
2. Master Tapes—gacha currency

2. Common materials—low priority
3. Furniture/cosmetics—no gameplay impact

Cost-Efficiency

Polychromes: Not farmable—always purchase regardless of rate

W-Engine Energy Modules: Event shop 50-100 currency vs. 40 energy + low drop rates—high priority

Dennies: Event shop 1,000 currency per 10,000 vs. 20 energy per 10,000—low priority

Original Chips: Event shop 30-50 currency vs. 20 energy + moderate drops—medium priority

Skip If Short on Currency

2. Common materials—minimal energy investment
3. Furniture/cosmetics—zero gameplay impact
4. Duplicate stockpiled items—check inventory first
5. Materials for unowned/unplanned characters

Advanced Tips

Simultaneous Event Management

Daily Must-Complete (15-30 min):

• Trust Invites for all characters
• Gilded Surprise login (Feb 14-23)
• Inter-Knot Membership claim
• Commission missions

Every 2-3 Days (30-60 min):

• Trust Events (cooldown-dependent)
• A Harmony of Delusions stages
• Fun Events for milestones
• Event shop monitoring

Weekly Focus (1-2 hours):

• Story progression for Trust unlocks
• Quality Time interactions
• Hollow Zero and Shiyu Defense
• Comprehensive shop review

Energy Calculation

Total Version 2.6 demand:

• A Harmony of Delusions: ~1,500-2,000
• Fun Events: ~300-500
• Trust: Minimal (time-gated)
• Permanent maintenance: ~500-700 weekly
• Total: ~2,500-3,500 across 46 days

Available F2P: ~11,500-13,800 (250-300 daily × 46)

Verdict: Substantial surplus—bottleneck is time management, not energy.

Time-Saving Shortcuts

1. Batch Trust Invites: Complete all characters in one session via Knock Knock menu
2. Route optimization: Farm later event stages for superior currency-per-energy ratios
3. Pre-plan shop exchanges: Calculate total earnings, allocate before shop opens
4. Story skip: Use skip functions for prerequisite content if already experienced
5. Login reminders: Set phone alarms for Gilded Surprise period (Feb 14-23)

Common Mistakes

Trust Content Misconception

Mistake: Assuming Trust can be delayed indefinitely

Reality: Daily invites are time-sensitive. Each missed day extends timeline to Friendly rank and Quality Time access.

Fix: Begin Trust immediately after character acquisition. Three-day cooldowns mean early starts compound into significant time savings.

Forgetting Quality Time Checks

Mistake: Reaching Friendly rank but never checking Knock Knock menu

Reality: Quality Time doesn't auto-trigger—manual access required

Fix: Check Knock Knock daily after Friendly rank. Set reminders every 2-3 days until all interactions completed.

Energy Waste

Mistake: Completing every task regardless of reward value

Reality: Not all content offers equal value

Fix: Calculate reward-per-energy ratios. Prioritize Polychromes, exclusives, high-rarity materials. Skip/delay Dennies or common materials if energy-constrained.

Shop Deadline Confusion

Mistake: Assuming shops remain open after event completion

Reality: Shops close with event expiration—unspent currency vanishes

Fix: Complete exchanges 24-48 hours before expiration for technical issue buffer.

Resource Top-Up Strategy

When Energy Refills Make Sense

Cost-effective when:

1. Approaching deadlines with incomplete S-tier rewards (missing 1,590 Polychromes costs more than refills)
2. Pulled characters late, need accelerated Trust progression
3. Building multiple characters simultaneously (event materials > permanent farming)

NOT cost-effective when:

• 7+ days remaining with normal progression on track
• Farming Dennies or common materials
• Haven't completed daily free energy sources

Polychrome Purchase Timing

Optimal windows:

1. During limited banner periods—direct conversion to pulls
2. Before event shop closures—enables last-minute exchanges
3. Approaching pity thresholds (10-20 pulls from guarantee)

Avoid when:

• No active banners interest you
• Far from pity with no immediate plans
• Major updates imminent (wait for announcements)

BitTopup Advantage

• Instant delivery: Immediate Polychromes for time-sensitive pulls
• Competitive pricing: Cost-effective vs. direct in-game purchases
• Secure transactions: Protected payment with buyer guarantees
• 24/7 support: Assistance during critical event periods
• Multiple payment options: Convenient purchasing
• High ratings: Established reputation

BitTopup's fast recharge ensures you never miss limited rewards due to resource constraints—emergency Polychromes for banner pulls or energy refills before event expiration.

FAQ

What should I prioritize first in ZZZ 2.6 events?

A Harmony of Delusions for 1,590 Polychromes and exclusives, daily Gilded Surprise logins (Feb 14-23), and immediate Trust progression for acquired characters. Complete story prerequisites for Trust unlocks before secondary events.

Can you miss permanent Trust unlocks?

Trust Levels are permanent after character acquisition. However, delaying wastes daily invite opportunities and extends Quality Time unlock timeline. Start Trust farming immediately.

How do Quality Time interactions work?

Requires Friendly Trust Rank (2-3 days of daily invites with aligned dialogue). Once unlocked, available at five permanent locations (Sixth Street, Lumina Square, Fantasy Resort, Ballet Twins Road, Port Elpis). Never expires.

Which event rewards expire in ZZZ 2.6?

A Harmony of Delusions (Pan Yinhu outfit, 1,590 Polychromes, Hamster Cage Pass) expires Mar 23. Gilded Surprise expires Feb 23. Event shops close with respective events. Trust and Quality Time remain permanent.

How many Polychromes from ZZZ 2.6 events?

A Harmony of Delusions: 1,590. Trust (both characters): 160 combined (80 each across Levels 2-4). Additional sources: 10-50 each. Total: ~1,750-1,800 Polychromes.

Are Quality Time conversations permanently missable?

No. Quality Time remains permanent after unlocking Friendly Trust Rank. Only missable element is time to reach Friendly—delaying Trust delays access, but content never expires once unlocked.
