Memory Film Currency
Memory Film is primary event currency. Mid-tier stages yield 20-30 currency per stamina. Natural stamina: 250 daily × 14 days × 25 average rate = 87,500 total currency without refreshes.
Full optimization pushes 75,000-120,000 currency depending on difficulty and team CP. Exchange for skill books, core dust, overload gear, and exclusive Label Archives materials (OUT OF UNIFORM, NONSENSE RED, Delusion Shattered).
Combat Power Requirements
Full clears need 180,000-220,000 team CP, though skilled players clear at 160,000 CP minimum. DPS units should be 35-40% of total team CP. Tier 7-8 gear sufficient for most encounters; Tier 9-10 needed for Phase 3 optimization.
Cube investments: Tempering for DPS, Vigor for tank/healer. Level 5 minimum across all cubes.
Low-Investment Burst Rotations
Core strategy uses Label or Centi (B1, 30-75 books), Liter (B2, 60-80 books), Rapunzel (B3, 55-70 books) = 145-225 books for support framework. Add flex DPS (Snow White, Maxwell, Alice, Harran) for 200-300 books total.
Skill breakpoints:
- Burst skills to level 7 (all units)
- Skill 1 to level 4 (universal)
- Primary DPS Skill 1 to level 7
- Label Skill 2 to level 7 (Phase 2 survival)
Burst Gauge Mechanics
Gauge fills through damage, hits, and time. Challenge Stage accelerates generation during vulnerability windows. 3-second window after Core Charge attack = optimal burst generation.
Flying Discs shot within 5 seconds prevent penalties—each missed disc reduces generation by 15%, stacking 3× (45% total). Clear back-row enemies with AoE during 8-10 second safe windows.
Why Efficiency Matters
F2P commanders need every skill book to count. Efficient rotations maximize currency per stamina while preserving resources. 87,500 natural stamina baseline requires zero refreshes.
Well-executed 3-burst rotation in Phase 3 delivers 30-40% boss HP damage per cycle, dramatically shortening encounters.
Budget Team Compositions
Optimal setup: Label (B1 Defender) or Centi (B1 alternative) + Liter (B2 Support) + Rapunzel (B3 Healer) + flex DPS.
Label: 70.4% damage reduction vs Electric Code, 30.15% final Max HP shields (10s duration). Bursting Heart: 70.4% damage reduction (5s, 20s cooldown).
Centi: 30-40 books at Burst 4, Skill 1 level 4, Skill 2 level 1. Ideal for newer accounts.
Liter: Burst 7 (Skill 1 level 4, Skill 2 level 1) = 60-80 books. Provides attack buffs and burst gauge acceleration.
Skill Investment Priority
- Burst skills to level 7 (all units)
- Skill 1 to level 4 (universal)
- DPS Skill 1 to level 7
- Label Skill 2 to level 7 (Phase 2 survival)
Rapunzel: Burst 7 (Skill 1 level 4, Skill 2 level 1) = 55-70 books. Healing scales with burst level—level 7 non-negotiable.
Flex DPS Options
- Snow White: Sustained damage, high fire rate
- Maxwell: Burst damage spikes for short windows
- Alice: AoE clearing + competitive single-target
- Harran: Specialized burst with positioning advantages
Choose based on available investment and mechanical comfort, not meta chasing.
Optimal Burst Rotation Sequences
Standard 3-burst rotation:
- Activate B1 (Label/Centi) as yellow core dims post-attack
- Trigger B2 (Liter) 0.5s after B1 completes
- Execute B3 (Rapunzel) 0.5s after B2
Timing ensures buff stacking and maximizes damage during vulnerability windows.
Phase-Specific Adjustments
Phase 1 (100%-70% HP): Core charges every 25-30s with 2-3s telegraphs. Charge gauge during telegraph, align full rotation with 3s post-charge window. Destroy both large cannons before Phase 2.
Phase 2 (70%-40% HP): Increased attack frequency. Wait 4-5s after core charge/cannon attacks, execute rotation within 2-3s safe window. Activate Label's Bursting Heart before rotation for survivability.
Phase 3 (40%-0% HP): Core charges every 15-20s with 3-4s vulnerability windows. Yields 30-40% HP per rotation—primary DPS race. Activate B1 after any attack concludes, maintain 0.5s intervals.
Damage Windows
Three windows:
- Primary: 3s post-core-charge (full burst rotations)
- Secondary: 2s post-jump landing (basic attacks, gauge building)
- Tertiary: 1.5s between small cannon barrages (high-damage basics)
Core charge telegraph: yellow weak spot brightens 2-3s before firing. Position behind cover while building gauge, emerge post-charge for full 3s window.
Memory Film Farming
Natural stamina: 250 daily × 14 days = 3,500 total. At 25 average currency rate = 87,500 without refreshes. Covers most essential shop items.
For maximum efficiency, buy NIKKE gems instant recharge through BitTopup for strategic stamina refreshes with fast delivery.
Daily Stamina Allocation
Allocate all 250 natural stamina to Challenge Stage during event. Skip equipment farming/story until after Jan 29. 20-30 currency per stamina significantly outvalues standard content.
Time expenditure around FULL BURST DAY (Jan 24-26) for potential bonuses. Complete Land Eater missions (Jan 16-18) first, then dedicate remaining stamina to Challenge Stage.
Farming Route Optimization
Select highest difficulty clearable in 3-5 minutes. Longer clears reduce efficiency despite higher rewards. Mid-tier often provides optimal currency-per-minute for budget teams.
Track average currency per stamina across 5-10 runs. Below 20 per stamina? Lower difficulty. Under 2-minute clears? Test one tier higher.
Stamina Management
87,500 baseline assumes zero overflow waste. Set login timers every 8-10 hours to prevent capping at max stamina (240-280 depending on level).
Calculate stamina needed: desired currency ÷ average rate. Example: 100,000 ÷ 25 = 4,000 stamina. Subtract natural regen (3,500) = 500 needed (2-3 refreshes).
Natural Regen vs Refresh Costs
Natural: 250 daily at zero cost = 3,500 across 14 days.
Refresh costs:
- 1st: 40 gems for 120 stamina (0.33 gems/stamina)
- 2nd: 80 gems for 120 stamina (0.67 gems/stamina)
- Escalates thereafter
Compare refresh costs vs shop gem value. 120 stamina = 3,000 currency (at 25 rate). Shop items at 500 currency = 6 items per refresh. Evaluate if items justify 40-80 gems.
Should You Buy Refreshes?
Purchase only after exhausting natural stamina and confirming targets unattainable otherwise. Prioritize first daily refresh (40 gems) for best value if pursuing full-clear (75,000-120,000 range). Avoid 3rd+ refreshes unless chasing absolute completion with excess gems.
F2P: skip refreshes unless sitting on 10,000+ gems with no banner priorities. 87,500 baseline covers essential rewards.
Boss Mechanics and Counters
Electric Code: three phases, escalating mechanics. Structure: 2 large cannons (one per side), 2 small cannons (one per side), central core with yellow weak spot.
Core Charge Attack
Yellow weak spot brightens 2-3s before firing—take cover immediately. Failing to cover = massive team-wide damage/wipes. Position behind cover during telegraph while maintaining basic attacks.
Post-charge vulnerability: exactly 3s. Core exposed, takes increased damage. Coordinate full burst sequences before next attack.
Missile Barrage and Cannon Destruction
Large cannons glow red before Missile Barrage, 2s targeting window with red ground circles. Destroy both before Phase 2 (70% HP) to prevent complications. Focus sustained fire during 8-10s safe windows.
Designate one cannon for elimination first, then switch. Partial damage on both = no benefit. Complete destruction prevents attack entirely.
Flying Disc Management
Discs appear periodically, must shoot within 5s. Each missed disc = 15% burst generation reduction, stacking 3× (45% total). Severely hampers rotation timing.
Prioritize disc destruction with AoE or rapid-fire DPS. Clear back-row enemies first during safe windows to reduce clutter and improve disc visibility.
Common Mistakes
Failed rotations: Incorrect timing between bursts. 0.5s delay between B1→B2 and B2→B3 ensures buff stacking. Too quick = desynchronization; excessive delay = wasted window.
Team Composition Errors
Multiple B1 units create rotation conflicts and reduce damage. Maintain one unit per burst type (I, II, III) + flex DPS. Duplicate types force suboptimal timing or unused skills.
Neglecting Label Skill 2 for Phase 2 = frequent wipes. 70.4% damage reduction non-negotiable for budget teams. Allocate 45-75 books despite opportunity cost—survival enables farming, wipes yield nothing.
Stamina Waste Scenarios
Attempting difficulty beyond capability wastes stamina on failed clears (zero currency). Test new tiers with 1-2 attempts before committing daily allocation. Drop one tier if clear rate below 80%.
Forgetting to claim daily stamina from mailbox/event rewards creates artificial scarcity. Check all sources before purchasing refreshes.
Event Completion Checklist
Daily priorities:
- Expend 250 natural stamina on Challenge Stage
- Complete Land Eater missions (Jan 16-18)
- Participate in FULL BURST DAY (Jan 24-26)
- Track total currency toward targets
Maintain spreadsheet tracking daily earnings to project finals and adjust strategy.
Minimum Investment for Full Rewards
Full rewards: 75,000-120,000 currency depending on shop priorities. Natural stamina yields 87,500, covering baseline without refreshes.
Invest 145-225 books across Label/Centi, Liter, Rapunzel for support, then add DPS based on resources. Target 160,000 minimum CP with optimal play, scaling to 180,000-220,000 for comfortable clears. Prioritize Tier 7-8 gear and level 5 cubes.
Memory Film Exchange Priority
- Exclusive Label Archives materials (OUT OF UNIFORM, NONSENSE RED, Delusion Shattered)—event-only, permanent collection value
- Skill books for ongoing progression
- Core dust for gear enhancement
Avoid items farmable in standard content (basic materials, common equipment). 20-30 currency per stamina too valuable for low-priority exchanges.
Last-Minute Farming (Jan 27-29)
Reserve final 72 hours for intensive farming if tracking shows shortfall. Purchase first daily refresh (40 gems) for best value-to-currency conversion. Coordinate with FULL BURST DAY conclusion (Jan 26) for residual bonuses.
Avoid panic-refreshing Jan 29 final hours—costs escalate rapidly beyond first daily. Target 90% desired currency by Jan 27, use final days for safety margin.
