Complete Boss Pattern Analysis
Destructible Parts System:
- 2 large cannons (one per side) - Priority targets
- 2 small cannons (one per side) - Secondary threats
- Central core with bright yellow weak spot
Phase 1 (100%-70% HP)
Core Charge Attack: Yellow spot brightens 2-3 seconds before firing. Take cover immediately. Creates 3-second vulnerability window after completion.
Missile Barrage (WIPE MECHANIC): Large cannons glow red, then fire one-shot missiles that pierce cover. Telegraph: 2-second targeting phase with red ground circles. Counter: Destroy both large cannons before they execute this attack.
Small Cannon Side Attacks: Moderate damage, non-threatening. Prioritize only when boss jumps to front position.
Flying Discs: Spawn after elite shield mobs jump in. Must shoot down within 5 seconds - each hit reduces burst generation by 15% (stacks 3×).
Mob Waves: Clear back-row first with AoE, chip large cannon health during 8-10 second safe windows.
Phase 2 (70%-40% HP)
Coordinated Attacks: If both large cannons intact, they fire simultaneously with core charge, creating overlapping damage zones.
Elite Shield Mobs: Spawn more frequently. Require pierce damage or shield-break specialists.
Jump Attack Changes: Telegraph reduced from 2 seconds to 1 second. Pre-emptive repositioning required.
Small Cannons: Fire during jump animations, creating crossfire patterns.
Phase 3 (40%-0% HP)
Core Charge Frequency: Increases to every 15-20 seconds (vs 25-30 in Phase 1).
Extended Vulnerability: Core remains exposed 3-4 seconds after attacks (vs 2-3 earlier). Allows 30-40% HP burst damage in single rotation.
Small Cannon Rapid-Fire: New pattern with knockback that interrupts burst animations. Position behind cover essential.
Damage Window Timing:
- Post-core-charge: 3 seconds (best window)
- Post-jump landing: 2 seconds
- Between small cannon barrages: 1.5 seconds
Lowest-Investment Team Composition
Core Structure:
- Burst I: Centi (tank/burst generator) or Label (premium option)
- Burst II: Liter (ATK buffs + burst acceleration)
- Burst III: Rapunzel (healer)
- Flex DPS: Snow White (optimal) / Maxwell / Alice / Harran (budget)
Phase 1 Investment (200-250 total skill books):
- Liter: Burst 7, Skill 1 lvl 4, Skill 2 lvl 1 (60-80 books)
- Centi: Burst 4, Skill 1 lvl 4, Skill 2 lvl 1 (30-40 books)
- Rapunzel: Burst 7, Skill 1 lvl 4, Skill 2 lvl 1 (55-70 books)
- Budget DPS (Maxwell/Alice): Burst 4, Skill 1 lvl 4, Skill 2 lvl 1 (50-65 books)
Phase 2 Optimization (+80-120 books):
- Label: Burst 1, Skill 1 lvl 4, Skill 2 lvl 7 (45-75 books)
- DPS enhancement: +35-45 books
Why This Works:
- Centi's manual taunt generates 25-30% faster burst gauge
- Liter's burst acceleration aligns rotations with 25-30 second boss cycles
- Rapunzel's healing negates chip damage
- Label's 70.4% damage reduction vs Electric Code covers full core charge + vulnerability window
- Label's shield: 30.15% final Max HP for 10 seconds
Power Benchmarks:
- Full clear CP: 180,000-220,000 (160,000 minimum with optimal play)
- DPS should be 35-40% of team CP
- Equipment: Tier 7-8 standard gear sufficient, tier 9-10 for Phase 3 optimization
- Cubes: Tempering (DPS), Vigor (tank/healer) to level 5 minimum

Investment Priority Guide
Skill Level Economics:
- Levels 1-4: 2-5 books each
- Levels 5-7: 8-15 books each
- Levels 8-10: 20-40 books each
- Full investment (one unit): 200-300 books
Priority Order:
- Burst skills to level 7 (all units) - affects multipliers, durations, cooldowns
- Skill 1 to level 4 (all units) - baseline functionality
- Primary DPS Skill 1 to level 7 - 50-60% of team damage
- Label's Skill 2 to level 7 (Phase 2) - team-wide buff scaling
- Support/healer Skill 2 stays level 1 - minimal impact
Equipment Priority:
- Correct main stats > tier level
- DPS: ATK weapon, Elemental Damage accessories
- Tank/Healer: Max HP all slots
- Overload gear: DPS first (15-25% stat increase), then supports
Cube Allocation:
- All cubes to level 5 before pushing any to level 10 (70-80% benefit, 30-40% cost)
- Tempering (DPS): ATK%, Elemental Damage% overloads
- Vigor (tank/healer): Max HP% overloads
Efficiency Breakpoint: 1,500 stamina spent = Phase 2 optimization worth it (25-30% faster clears, 15-20% better consistency)
Optimal Burst Rotation Strategy
Burst Generation Management:
- Manual Centi: Taunt after boss completes attack pattern = 15-20% burst gauge per cycle (25-30% faster than auto)
- AoE for mobs: Each mob = 2-3% gauge, elite mobs = 3× standard mob value
- Label's passive: 1-second stun per stack (max 2) on attackers = extra gauge + DPS protection
Phase-Specific Timing:
Phase 1: Align with post-core-charge window. Begin charging during telegraph (2-3 sec before) so Burst I activates as vulnerability opens.
Phase 2: Wait for both core charge AND cannon attacks to complete (4-5 sec sequence), then execute full rotation in 2-3 sec window.
Phase 3: Flexible timing - activate Burst I after ANY attack pattern completes. Increases total rotations from 4-5 to 6-7 (20-25% more damage).
Rotation Sequence:
- Label/Centi Burst I (as yellow core dims)
- Liter Burst II (+0.5 sec after Burst I starts)
- Rapunzel Burst III (+0.5 sec after Burst II starts)
Common Mistakes:
- ❌ Burst I during attack animation (wastes damage reduction)
- ❌ Burst III before Burst I/II complete (misses Liter's 10-sec ATK buff)
- ❌ Auto-burst (30-40% damage loss vs manual)
Manual vs Auto:
- Manual essential for Phase 2-3 consistency (15-20% faster clears)
- Auto viable for Phase 1 if 200,000+ CP
- Hybrid: Manual first rotation, auto cleanup below 40% HP (80-90% efficiency)
Step-by-Step Clear Walkthrough
Pre-Fight Checklist:
- ✅ Equipment main stats: ATK (DPS weapons), Max HP (tank/healer), Elemental Damage (DPS accessories)
- ✅ Burst order: Label/Centi slot 1, Liter slot 2, Rapunzel slot 3
- ✅ Manual burst control enabled
Phase 1 Execution:
- Clear initial mob wave (back-row first with AoE)
- Chip large cannon health during mob waves (8-10 sec windows)
- First burst rotation after first core charge attack
- Focus large cannons during rotation - destroy at least one before 70% HP
Phase 2-3 Execution:
- Destroy second large cannon immediately at 70% HP (removes missile barrage)
- Shoot flying discs within 5 seconds of elite mob spawns
- Switch to core once both large cannons destroyed
- Maintain burst timing with post-attack windows
Manual Play Critical Moments:
- Reposition behind cover 2 seconds before core charge completes
- Activate Centi taunt after boss lands from jumps (1-2 sec stationary window)
- Focus fire elite shields (one elite = 3-4 standard mobs for burst gauge)
Consumables (If Needed):
- ATK buffs: 15-20% damage for 60 sec, use if consistently reaching Phase 3 with 15-20% HP remaining
- Burst gauge: 20-30% faster rotations, reserve for final-day farming pushes

Support Alternatives:
- Liter: Optimal burst acceleration
- D/Dolla: 15-20% longer clears, less forgiving timing
F2P Composition: Centi + Neon + Anis + Pepper (zero gacha, 150-180 sec clears at 45-75 total books)
Troubleshooting Common Failures
Team Dies Before Phase 2:
- Healer Burst level too low (need Burst 7 minimum)
- Missile barrage hitting (destroy large cannons during mob waves)
- Elite mob accumulation (bring AoE unit, use pierce damage)
Not Enough DPS:
- Wrong equipment main stats (30-40% damage loss)
- Burst mistiming (activate during vulnerability windows, not attack animations)
- Skill levels below threshold (DPS needs Burst 7, Skill 1 lvl 7, Skill 2 lvl 4)
Burst Timing Issues:
- Incorrect slot assignments (verify Burst I/II/III order)
- Delayed Burst III (tap sequence: I → wait 0.5s → II → wait 0.5s → III)
- Auto-burst enabled (disable in settings)
Random Wipes:
- Flying disc debuffs (destroy within 5 sec of spawn)
- Core charge without defensive buffs (activate Burst I before each core charge)
- Small cannon crossfire (reposition behind cover when boss stance shifts backward)
Advanced Tips
Hidden Mechanics:
- Core weak spot vulnerable 0.5-1 sec longer than visual indicator (continue attacking after dim)
- Large cannons take 15-20% bonus damage during firing animations
- Elite shields drop for 0.5 sec after jumping in (burst damage can bypass shields)
Screen Position Optimization:
- Center camera between both cannons (faster target switching)
- Max zoom in Phase 3 (track small cannons + flying discs)
- Manual aim mode during burst rotations (95-100% weak spot hit rate vs 70-80% auto)
Practice Strategies:
- 3-4 practice runs at 10 stamina (reduces failed attempt waste by 60-70%)
- Record successful clears, review for optimization
- Watch community clear videos for pattern recognition
Future Challenge Stage Prep:
- Consistent design: 3-4 destructible parts, 2-3 phases, vulnerability windows aligned with burst timing
- Maintain diverse roster (all damage types + elements)
- Stockpile 100-150 skill books between events
FAQ
What's the minimum CP to clear SIN EDITOR? 160,000-180,000 for Phase 1 with optimal mechanics. 180,000-220,000 for Phase 2-3 (15-20% lower with Label). DPS should be 35-40% of total team CP.
Which free NIKKEs can clear this boss? Centi + Neon + Anis + Pepper (zero gacha). Phase 1 clears at 45-75 total books, 150-180 sec clear times. Destroy both large cannons before Phase 2 to compensate for lower healing.
How do you counter the wipe mechanic? Destroy both large side cannons before they fire missiles. Focus cannons during 8-10 sec mob wave windows. Snow White: 1 rotation per side. Budget teams: 2-3 rotations per side. Once destroyed, mechanic permanently removed.
What are the attack patterns per phase?
- Phase 1 (100-70%): Core charge every 25-30s, missile barrages, side attacks
- Phase 2 (70-40%): Coordinated cannon attacks, more elite mobs, 1-sec jump telegraphs
- Phase 3 (40-0%): Core charge every 15-20s, 3-4 sec vulnerability windows, rapid-fire knockback barrages
Which burst rotation works best? Label/Centi Burst I (as core dims) → Liter Burst II (+0.5s) → Rapunzel Burst III (+0.5s). Manual control essential - auto-burst loses 30-40% damage.
What skill levels for F2P clear? Phase 1: DPS (Burst 7/Skill 1 lvl 7/Skill 2 lvl 4), Liter (Burst 7/Skill 1 lvl 4/Skill 2 lvl 1), Centi (Burst 4/Skill 1 lvl 4/Skill 2 lvl 1), Healer (Burst 7/Skill 1 lvl 4/Skill 2 lvl 1). Total: 200-250 books. Phase 2: +80-120 books for Label + DPS optimization.
