Optimal Daily Stamina Script
Morning: First Priority
- Log in after reset, claim 5 free event stamina
- Spend on stages matching your synchro level:
- Synchro 1-120: Core dust stages only
- Synchro 121-160: Split between battle data and core dust
- Synchro 161-200+: Core dust priority (10,000 per level beyond 200)
- Use bonus Nikkes—Velvet's +60% significantly boosts currency

- Pair with Reward Boost Nikkes (Modernia, Scarlet) for +50 currency drops
Midday: Regular Content
Event stamina doesn't regenerate throughout the day. Focus on:
- Regular campaign stamina (288/day at 1 per 5 min)
- Simulation rooms: 80 Skill I, 40 Burst I, 60 Skill II, 30 Burst II, 16 Skill III, 8 Burst III, 30 Code manuals daily
- Union Raid attempts (no stamina cost)
- Interception (3 free daily entries)
Evening: Safety Net
Check event stamina—if 10/5 or higher, spend 5 minimum before reset. For regular stamina:
- First-time clears if progressing story
- Targeted material farming for bottlenecks
- Coordinated Operation Zix attempts (January 30-February 1)
Weekend: Batch Farming
Don't buy event tickets with gems until hard mode unlocks—better currency ratios. Use weekends for:
- Simulation Overclock at max ratio 25: 168 Skill I, 84 Burst I, 124 Skill II, 62 Burst II, 56 Skill III, 28 Burst III (2.1x multiplier)

- Extended farming sessions
- Hard mode attempts once unlocked
Stage Priority Matrix
Tier 1: Event Stages
Event stages drop Pro Maid Certificates—time-limited until February 11. Focus on best currency-per-stamina ratio matching synchro needs:
- Synchro 1-120: Stages with event currency + core dust

- Synchro 121-160: Event currency + battle data (1H per clear)
- Synchro 161-200+: Event currency + core dust
Rewards: 1-4 counts per clear depending on difficulty.
Tier 2: High-Value Materials
After daily event stamina:
- Core dust stages (permanent content)
- Battle data farming (synchro 200+ only, after event stages maxed)
- Credits = lowest priority (abundant through daily activities)
Tier 3: Progression
Story progression unlocks simulation rooms at Chapter 20+. If below Chapter 20, calculate if stamina investment pays off before February 11. Otherwise, delay story until post-event.
Avoid
- Equipment farming (low RNG rates)
- Materials available in event shop
- Stages misaligned with synchro bottleneck
Stamina Efficiency
Natural Regeneration
- Event: 5/day flat = 65 total over 13 days
- Campaign: 288/day (1 per 5 min)
- Simulation: Daily attempts, no stamina cost
Refill Math
First campaign refill: 100 gems = 120 stamina. But refills don't give event stamina—limited utility during Fatal Maid.
Event ticket purchases: Skip until hard mode. Natural regen = 65 tickets over event.
Gem Priority: Save for Q1 2026 collabs. 200 Gold Mileage Tickets needed for guaranteed unit via mold exchange. Each refill = potential missed collab pull.
For gem stockpiling: Goddess of Victory NIKKE gem recharge via BitTopup offers secure transactions.
F2P vs. Low-Spender
F2P: Never buy refills. Gems = scarcest resource for pulls and inventory.
Low-Spender: Single refill justified only if 1-2 days from critical shop purchase before deadline.
Both benefit equally from simulation optimization—no stamina/gem cost.
Event Shop Priorities
Must-Buy (Tier 1)
- Recruit Vouchers: Highest priority. Limited quantity, enables collab pulls. Gone after February 11.
- Skill Books: Supplements simulation farming. Level 7→10 Burst needs 714 Burst I, 505 Burst II, 315 Burst III, 610 Code.
- Core Dust Cases: For synchro 161-200+. 10,000 per level beyond 200.
High-Value (Tier 2)
- Battle Data: For synchro <200 facing dual bottlenecks
- Consoles: If missing critical pieces for meta teams
- Credits: Lowest efficiency—only if completely blocked
Skip
- Items farmable at better rates elsewhere
- Event tickets before hard mode
- Cosmetics (unless completionist)
Sensual Rabbit costume = Mission Pass, not shop.

30-Day Accumulation: 2,400 Skill I, 1,200 Burst I, 1,800 Skill II, 900 Burst II, 480 Skill III, 240 Burst III, 900 Code = enough for 1 complete Level 10 Burst + surplus

- Farming shop-available materials: Check shop first
- Buying tickets before hard mode: Wait for better ratios
- Missing simulation clears: 234 manuals/day lost permanently
FAQ
How much stamina does Fatal Maid require daily?
5 free event stamina daily, 1 per stage. Spend 5 minimum to receive next day's allocation (caps at 10). Total 65 free stamina over 13 days.
What to buy first in shop?
Recruit Vouchers → Skill books → Core dust. Vouchers gone after Feb 11. Battle data for synchro <200. Credits lowest priority.
Should I use stamina refills?
No, unless high spender. 5 daily free stamina covers critical shop items. Save gems for Q1 2026 collabs (28,000 minimum). Campaign refills don't give event stamina.
How many gems for Q1 2026 collab?
28,000 for 1 guaranteed unit (200 Gold Mileage Tickets). 56,000 for 2 units, 84,000 for 3. Worst-case RNG calculation.
Best farming route?
Spend 5 daily event stamina on synchro-matched stages: core dust (1-120, 161-200+) or battle data + core dust (121-160). Use bonus Nikkes (Velvet +60%). First-time clears before repeats. No ticket purchases until hard mode.
Balance Fatal Maid with regular progression?
Event stamina first daily (time-limited until Feb 11). Regular campaign stamina on permanent content. Daily simulation clears for stockpiling. Union Raid doesn't use stamina. Story progression post-event unless unlocking simulation rooms (Chapter 20+).
