Core mechanic: Mesmerized state deals 210-500% ATK Physical DMG (guaranteed CRIT) + grants all teammates +100% CRIT DMG for 12 seconds. Powerful enabler for CRIT-focused Physical DPS.

Exclusive vs Standard Channel
Exclusive Channel:
- Limited characters with 50/50 on first S-Rank
- Guaranteed featured character on second S-Rank if first was off-banner
- Pity carries across all limited banners
Standard Channel:
- Permanent pool, no rate-ups or guarantees
- Independent pity (doesn't transfer)
Use Encrypted Master Tapes (bought with Polychromes) exclusively on Exclusive Channel for limited characters.
Pull Rates Breakdown
Base Rate: 0.6%
Every pull = 0.6% S-Rank chance (roughly 1 in 167). Applies uniformly to pulls 1-74. No cumulative increase until soft pity.
When S-Rank drops: 50% Sunna, 50% off-banner. Losing 50/50 guarantees next S-Rank is featured character.
Soft Pity: Pull 75
Rate jumps from 0.6% to 6% at pull 75—10x increase. Continues escalating through pull 89.
Realistic expectation: Most S-Ranks arrive pulls 75-80 (~60% probability before hard pity). Budget for this range, not the 90-pull max.
Soft pity + guaranteed status = best position possible.
Hard Pity: Pull 90
Pull 90 = 100% S-Rank guarantee. Caps worst-case at 14,400 Polychromes (90 × 160).
Resets immediately upon any S-Rank. 50/50 system operates independently—hitting hard pity doesn't guarantee featured character without prior 50/50 loss.
Absolute worst case: 180 pulls (28,800 Polychromes) for guaranteed featured—90 for first S-Rank losing 50/50, then 90 more.
Pity Carry-Over
Pity persists across all Exclusive Channel banners. Pulls from previous versions count toward Sunna. Both pity count AND 50/50 status carry forward.
Does NOT carry between banner types. Exclusive, Standard, W-Engine, and Bangboo banners have separate counters.
Track Your Pity
Signal Search → Exclusive Channel → Details → History. Count pulls since last S-Rank. Game doesn't display count—manual tracking required.

Polychrome Costs
Per Pull: 160 Polychromes
One Encrypted Master Tape = 160 Polychromes. No bulk discounts.
Quick math: Total Polychromes ÷ 160 = pull count.
Guarantee Costs
Worst case (180 pulls): 28,800 Polychromes
Realistic (soft pity twice at ~75): 24,000 Polychromes (150 pulls)
With guaranteed status: 14,400 max, ~12,000 realistic
At pull 60 with guarantee? Only 30 pulls to soft pity = 4,800 Polychromes.

Sunna Value Assessment
Role & Teams
Physical Support amplifying team CRIT DMG. Minimal field time—activate Mesmerized, apply +100% CRIT DMG buff, swap to DPS.
Best for: Physical DPS teams lacking CRIT DMG. Characters with high CRIT Rate but low CRIT DMG gain most value.
Limited for: Non-Physical teams. Element-specific support—no value without Physical DPS investment.
Meta Position
+100% CRIT DMG = 50% damage increase for characters at 200% base CRIT DMG. Significant for Shiyu Defense time-attacks.
Pull if: You run developed Physical DPS needing CRIT support.
Skip if: No Physical DPS, or existing supports cover this role.
12-second buff duration = forgiving rotation windows.
Mindscape Investment
C0 = full functionality. Mesmerized state and team buff work without dupes.
Higher Mindscapes optimize, don't unlock core features. Each copy costs up to 28,800 Polychromes—C6 can exceed 150,000.
F2P priority: Roster breadth over depth. Multiple C0 S-Ranks > single C6.
Pull Strategy
Single vs 10-Pull
Mechanically identical rates. 10-pull = convenience only.
Strategy: Use 10-pulls at pulls 0-70, switch to singles at 71+ for precise pity control. Prevents wasted pulls if S-Rank arrives at pull 89 during 10-pull (though excess carries forward).
F2P Approach
Conservative: Save 28,800 before pulling—guarantees acquisition regardless of luck. Requires patience across multiple versions.
Aggressive: Pull with available resources—risks fragmentation without completing any character.
Recommended: Save for guarantee on high-priority characters only. Skip low-priority banners entirely. Sunna = priority only if you need Physical support.
Spender Strategy
Monthly subscription first (best ratio). Beyond that, set per-character budget, pull until limit or acquisition.
Losing 50/50 on skippable banner = guaranteed status for next desired character. Convert bad luck into strategic advantage.
Mindscape chasing: Calculate total cost before committing. C6 can exceed 150,000 Polychromes.
Pull or Skip?
Pull if:
- Developed Physical DPS lacking CRIT support
- Guaranteed status from previous 50/50 loss
- Sufficient resources (28,800 or current pity + reserves)
- Phase 2 Aria doesn't fit roster
Skip if:
- No Physical DPS synergy
- 50/50 status with insufficient resources
- Aria better addresses gaps (Ether Anomaly)
- Future versions have higher priorities
Wait for community testing during week 1 if uncertain. 21 days = ample research time.
Myths & Facts
Myth: 10-pulls have better rates
False. Each pull = identical 0.6% regardless of method. No bonus for bulk pulling.
Myth: Pull timing affects luck
False. Server-side RNG immune to timing. No advantage at specific hours/days.
Fact: Probability independence
Each pull = independent event. Previous results don't influence future pulls (except pity). Bad streaks don't create due outcomes.
Verify rates: Signal Search → Details → Probability tab. Regulatory requirements mandate accurate disclosure.
Realistic expectations: ~40% of players reach soft pity (75) without base rate S-Rank. Budget for 75-80 pulls, treat early drops as bonuses.
Resource Maximization
Daily/Weekly Income
- Daily Commissions: 60/day (10-15 min) = 1,260 over 21 days
- Hollow Zero: 4,640/week = 13,920 total (87 pulls worth)
- Shiyu Defense: 1,008/cycle—challenging but high value
One-time sources: Combat sims, exploration, character stories. New players have extensive untapped reserves.
Events
Gilded Surprise (Feb 14-20): 600-1,200 Polychromes, accessible requirements.

Long-Term Planning
Rank desired characters across future versions. Allocate to top priorities, skip lower ones.
Track pity status across banner types. Know Exclusive Channel count, 50/50 status, Polychrome reserves for accurate forecasting.
Roster breadth > depth. Multiple C0 S-Ranks enable diverse teams and flexible content responses.
