Banner Overview: Timeline and Details
Release Date and Duration
Sunna's Exclusive Channel launches February 6, 2026 at 11:00 AM UTC+8, ending March 4, 2026 at 11:59 AM UTC+8. This 26-day Phase 1 window features Sunna, an S-Rank Physical Support from Angels of Delusion, designed to amplify Physical DPS through her Mesmerized debuff.
Pity carries over between limited character banners but stays separate from W-Engine and standard pools. Need resources fast? Buy Zenless Zone Zero Polychromes top up via BitTopup for competitive pricing and instant delivery.
Character Details
Sunna has 0.6% base pull rate on Exclusive Channel. Her Mesmerized debuff deals 500% ATK Physical damage with guaranteed crits and +50% CRIT DMG (12s duration). Best paired with Aria, Billy, or Ye Shunguang.
Signature W-Engine Thoughtbop provides 713 base ATK (level 60) and 140% Energy Regeneration (0.6 Energy/sec off-field), enabling ultimates every 15-18 seconds vs 25-30 with alternatives.
Banner Deadline Significance
March 4, 2026 cutoff creates urgency—limited characters may not return for 6-12 months. Time-gated content like Gilded Surprise (February 14-23) provides 4,000 Polychrome value through 25 free draws, but missing these windows permanently reduces earning potential.
W-Engine Banner
Thoughtbop runs separate pity (80 pulls hard pity = 12,800 Polychromes). Increases Energy Regeneration to 140%, enabling 15-18s ultimate rotations. EX Special grants stacking Physical DMG bonuses up to 25% plus 10% ATK (40s duration).
Character acquisition takes priority unless you've already guaranteed Sunna.
Pity System Mechanics
Polychrome Conversion
- 160 Polychromes = 1 pull
- 1,600 Polychromes = 10 pulls (no bulk discount)
- 28,800 Polychromes = 180 pulls (max guarantee)
Encrypted Master Tapes function identically but only work on Exclusive Channel. Version 2.6 provides ~16 tapes (2,560 Polychrome equivalent). Use these before converting Polychromes.
Hard Pity: 90-Pull Guarantee
S-Rank guaranteed at 90 pulls maximum. Counter resets immediately upon any S-Rank acquisition. Costs 14,400 Polychromes (90 × 160). Check current pity in Signal Search Records.
Soft Pity: Pull 75+
Soft pity starts at pull 75, increasing base 0.6% rate to ~6.6% per pull. Most S-Ranks appear at pulls 78-82. Players at 60-70 pity enter high-probability zone where each pull carries significantly better odds.
50/50 System
First S-Rank on limited banner: 50% chance for featured character, 50% for standard pool. Winning secures Sunna for 14,400 Polychromes or less. Losing activates guarantee—next S-Rank will be featured character.
Worst case: 180 pulls (28,800 Polychromes)—90 to hit hard pity and lose 50/50, then 90 more for guaranteed Sunna.
Pity Carryover
Pity persists across all Exclusive Channel banners indefinitely. 60 pulls on Sunna's banner carry to version 2.7's character banner. Guarantee status from lost 50/50 remains active until consumed.
Polychrome Requirements by Scenario
Zero Pity, No Guarantee
28,800 Polychromes maximum (180 pulls). Assumes losing 50/50 at hard pity (14,400), then another hard pity for guarantee (14,400).
Reality: Soft pity means ~78% of S-Ranks occur at pulls 75-89. Most players spend 12,000-14,400 Polychromes if winning 50/50.
Lost 50/50 (Active Guarantee)
14,400 Polychromes maximum at hard pity. Soft pity likely triggers at 12,000-13,600 Polychromes (75-85 pulls). Check Signal Search Records—if last S-Rank was off-banner (Koleda, Rina, Lycaon), guarantee is active.
Mid-Pity Starts
Calculate by subtracting current pity from 90:
- 30 pity: 60 pulls needed (9,600 Polychromes)
- 60 pity: 30 pulls needed (4,800 Polychromes)
At 60 pity without guarantee: ~50% odds of Sunna within 15-30 pulls (2,400-4,800 Polychromes) due to soft pity. Losing 50/50 requires rebuilding from zero (12,000-14,400 more).
Master Tape Stockpile
Version 2.6 provides 16 Encrypted Master Tapes (2,560 Polychrome value) through battle pass, events, and login bonuses. Use these first before converting Polychromes. Never buy Standard Master Tapes with Polychromes—permanent banner offers no guarantees.
Polychrome Income: February 6 - March 4

Hollow Zero
4,640 Polychromes/week × ~3 weeks = 13,920 Polychromes through investigations and milestones.
Monthly Login & Membership
Inter-Knot Membership: 90 Polychromes/day × 26 days = 2,340 Polychromes + 300 bonus = 2,640 total (requires real money).

- HIA Club (3 min): Daily check-in
Extend on Shiyu Defense reset days and during limited events.
Shiyu Defense Priority
Floor 10 yields 200 Polychromes/cycle vs floor 7's 100—a 100% increase. Over two cycles, that's 200 extra Polychromes.
Stuck? Analyze failures: low damage = invest in DPS/W-Engines; survivability issues = supports/defensive gear. Team composition adjustments (element matching, stun windows) often beat raw stat increases.
Complete Story Early
Claim A Harmony of Delusions' 1,200-1,590 Polychromes during week one to clarify if you're on track. Delaying until late February creates unnecessary pressure.
Event Priority
- Gilded Surprise (Feb 14-23): 25 draws = 4,000 value
- A Harmony of Delusions: 1,200-1,590 Polychromes
- Combat challenges: 400-600 Polychromes
- Mini-games: 200-400 Polychromes
Limited time? Focus on top-tier events. Strategic 80% completion of high-value content beats 100% of mid-tier.
Hidden Sources
Achievements: 20-60 Polychromes each. Version 2.6 adds 300-500 through story, enemies, exploration.
Exploration caches: 200-400 Polychromes in hidden locations, puzzles, NPC chains. No combat required—just time and attention.
Spending Options
Monthly Card
Inter-Knot Membership: 90 Polychromes/day × 30 days = 2,700 + 300 instant = 3,000 Polychromes. ~$4.99 USD = 600 Polychromes/dollar (best value). Activate at version launch for maximum 26-day value.
Battle Pass
Premium track: 1,680 Polychromes + 4-5 Encrypted Master Tapes (640-800 value) = 2,400-2,500 total plus materials. ~$9.99 USD. Better overall account value but lower pure Polychrome efficiency than monthly card.
Requires active play to reach level 50. Casual players should prioritize monthly card.
Light Spender Analysis
Monthly card + battle pass = 5,400-5,700 Polychromes for ~$15 USD. Combined with F2P 13,000-15,000 = 18,400-20,700 total (115-129 pulls).
Sufficient for guarantee if you lost previous 50/50 (14,400 needed). Starting from zero without guarantee needs favorable 50/50 luck or additional purchases.
Direct Polychrome Packs
Worst value: 100-200 Polychromes/dollar vs monthly card's 600. First-time bonuses double rates temporarily. Only justify for last-day emergency shortfalls.
Optimal Spending Strategy
- Activate monthly card February 6 (max 26-day value)
- Buy battle pass if actively playing daily
- Avoid direct packs unless emergency
- Track pity weekly to identify if more spending needed
Cost: $15 max, provides 5,400-5,700 Polychromes. Total with F2P: 18,400-20,700 (enough for guarantee if you have active guarantee, or 115-129 pulls toward worst case).
Time-Gated Content
Limited Events
Gilded Surprise (Feb 14-23): 9-day window, 25 draws = 4,000 value. Missing this cuts Phase 1 F2P income by ~30%. Likely requires daily participation.
Other events run 7-14 days, contributing 400-800 Polychromes each. Calendar event schedules at launch to avoid conflicts.
Weekly Resets
Shiyu Defense: Bi-weekly resets, two cycles in Phase 1. Missing one cycle = 800 Polychromes lost (5 pulls). Complete 1-2 days before reset if unavailable during reset period.
Hollow Zero: Weekly investigations, 4,640 Polychromes/week × 3 weeks. Flexible completion within each cycle—complete early to avoid event deadline conflicts.
Story Rewards
A Harmony of Delusions: 1,200-1,590 Polychromes in 2-4 hours. Claim during Phase 1 for Sunna's banner. Delaying until after March 4 wastes immediate utility.
Exploration Checklist
New zones contain 300-500 Polychromes in caches, achievements, puzzles. Don't expire but contribute to Phase 1 when claimed promptly.
Hollow Zero milestones: 4,640 Polychromes weekly. Prioritize efficient completion over perfect performance—90% rewards in 60 min beats 100% in 120 min.
Common Mistakes
Myth: Pity Resets at Banner End
False. Pity persists across all Exclusive Channel banners indefinitely. 60 pity on Sunna carries to version 2.7's character banner. W-Engine and standard banner pity are separate, but within each category, pity never resets.
Mistake: Standard Banner Polychrome Pulls
Never convert Polychromes to standard pulls. No guarantee mechanism exists. Only use Standard Master Tapes earned through gameplay. New players waste 1,600-3,200 Polychromes here before learning.
Misunderstanding Soft Pity
Soft pity at pull 75 increases rate from 0.6% to ~6.6%—doesn't guarantee S-Rank by 80-85. Each pull 75-89 has ~10× higher chance, but unlucky players still hit hard pity at 90.
Budget for hard pity. Treat soft pity as probable cost reduction, not guarantee. Statistical average: pulls 78-82, but individual results vary.
Ignoring W-Engine Costs
Thoughtbop requires separate 80-pull pity (12,800 Polychromes). Character + weapon worst case = 41,600 Polychromes.
Secure character first, then evaluate weapon. Sunna functions with Weeping Gemini or Kaboom the Cannon—Thoughtbop is luxury, not necessity.
Should You Pull?
Meta Viability
Sunna specializes in Physical damage via Mesmerized debuff (500% ATK Physical damage, guaranteed CRIT, +50% CRIT DMG) and team ATK buffs. Optimal with Aria, Billy, Ye Shunguang.
Value diminishes in non-Physical teams. Without invested Physical DPS, evaluate if 14,400-28,800 Polychrome investment justifies building entire Physical team (months of resources).
Version 2.7+ Leaks
Community leaks suggest broader-compatibility characters coming. Spending 28,800 on Sunna leaves minimal resources for version 2.7's first banner.
Conservative approach: Skip Sunna, accumulate pity/Polychromes for future flexibility. Works best for diverse rosters not needing Physical support, or players willing to wait 6-12 months for rerun.
Roster Analysis
Pull if:
- Invested Aria/Billy/Ye Shunguang (she amplifies existing investments)
Skip if:
- Lacking Physical DPS (invest in DPS first)
- Needing Stunners/universal supports (address immediate gaps)
- New account <30 days (focus on versatile characters)
Skipping doesn't waste pity—pulls carry to future banners.
W-Engine vs Character Priority
W-Engines offer lower value than characters (narrower applicability). Thoughtbop only benefits Sunna; new S-Rank enables new team comps.
Alternative W-Engines provide 70-85% of Thoughtbop's performance at zero cost. Weeping Gemini (Energy Regen, ATK%) or Kaboom the Cannon (CRIT Rate, damage amp) allow functional builds, preserving 12,800 Polychromes for future characters.
FAQ
How many Polychromes guarantee Sunna?
28,800 maximum (180 pulls) worst case. With active guarantee from previous lost 50/50: 14,400 (90 pulls). Soft pity typically reduces to 12,000-14,400 for most players.
When does Sunna's banner end?
March 4, 2026 at 11:59 AM UTC+8. 26-day window from February 6 launch. Missing deadline means 6-12 month wait for potential rerun.
Can F2P get Sunna before March?
F2P earns 13,000-15,000 Polychromes in Phase 1 (81-94 pulls). Sufficient for guarantee only with active guarantee from previous lost 50/50. Zero pity without guarantee needs favorable 50/50 luck or spending.
Does pity carry over?
Yes, across all Exclusive Channel character banners indefinitely. W-Engine and standard banner pity are separate systems.
What is soft pity?
Starts pull 75, increasing S-Rank rate from 0.6% to ~6.6% per pull. Most players get S-Rank at pulls 75-89 vs hard pity at 90. Reduces average cost but doesn't guarantee early acquisition.
Is Sunna worth pulling?
Exceptional for Physical teams (Aria, Billy, Ye Shunguang). Mesmerized debuff (500% ATK Physical damage, guaranteed CRIT, +50% CRIT DMG) and ATK buffs substantially boost Physical output. Minimal value for Elemental/Ether teams—specialist choice, not universal support. Without invested Physical DPS, evaluate if building entire Physical team justifies 14,400-28,800 investment.
