Understanding New Eridu City Fund XP Mechanics
The City Fund operates as a seasonal progression system unlocked after Main Story Chapter 1 Cat's Lost & Found. Unlike Agent or Proxy experience, City Fund XP exclusively advances Battle Pass levels through accumulated points from tasks and Investigator Logs.
Three Investigator Log types determine progression speed:
- Senior Investigator Logs: 3000 XP per use (most efficient)
- Official Investigator Logs: 600 XP each
- Trainee Investigator Logs: 100 XP each
This 30:6:1 ratio shapes optimal farming strategies. Players can buy zzz monochrome film through BitTopup for secure, instant delivery of premium resources.
How City Fund XP Differs from Agent/Proxy XP
City Fund experience operates independently from character progression. Agent XP enhances individual character levels, while Proxy Level reflects overall account progression. City Fund XP exclusively tracks Battle Pass advancement, resetting each seasonal cycle.
This separation allows new players with low-level Agents to achieve Level 50 through consistent task completion. Current season ends 2026-02-02 03:59 server time, with Premium Plan purchases closing at 02:59.
XP Calculation Formula and Multipliers
City Fund XP accumulates through direct log consumption—no multiplicative bonuses. Each Senior Log adds exactly 3000 XP regardless of Inter-Knot Level or character strength.
Daily Errands provide the foundation: 3 Official Investigator Logs worth 1800 XP combined. Tasks include login confirmation, purchasing coffee, completing newsstand scratch cards, and visiting the video store. Unlocks after meeting Nekomata during Explosive Last Train quest.
Battery Charge caps at 240 maximum, regenerating 1 point per 6 minutes. Coffee at Coff Coffee restores 60 Battery Charge, enabling extended Combat Simulation sessions.
Level 50 Requirements: Total XP Breakdown
Level 50 demands systematic XP accumulation. Players starting from Level 40 face approximately 30,000-40,000 XP requirements. Final 10 levels typically require increased XP per level.
Premium Plan purchasers gain 10 instant Battle Pass Levels, reducing grind by 20-25%. The $19.99 investment grants 888 total Polychrome alongside these levels, while $9.99 Growth Plan provides 680 Polychrome without level boosts.
Current XP Gap Assessment: Where You Stand
Calculate your remaining XP requirement for realistic timelines:
- Level 45: 15,000-20,000 XP needed
- Level 48: 6,000-9,000 XP needed
- 3000 XP scenario: Roughly one day of intensive farming
Players can zenless zone zero monochrome top up via BitTopup for stamina refreshes during critical final hours.
Quick XP Calculator: Hours Needed Per Gap Size
3000 XP gap: 4-6 hours active gameplay with efficient Battery Charge management. Complete Daily Errands for 1800 XP, then farm one Senior Log through Combat Simulations for remaining 1200 XP.
6000 XP gap: 8-12 hours across two daily cycles. First day covers Daily Errands (1800 XP) plus two Senior Logs (6000 XP).
9000+ XP gap: 2-3 day schedules. Daily Errands contribute 5400 XP across three days, requiring three additional Senior Logs (9000 XP) from Combat Simulations.
3000 XP Scenario: Realistic Timeline
Morning optimization begins with Daily Errands immediately after server reset. Login, coffee purchase, newsstand interaction, and video store visit consume 10-15 minutes while granting 1800 XP—60% of the 3000 XP target.
Remaining 1200 XP requires one Senior Log from HIA Club Combat Simulations. Access requires Inter-Knot Level 10 for Combat Simulation (S5) or Main Chapter 1 completion for (S2) difficulty.
Battery Charge expenditure for one Senior Log typically requires 40-60 charge depending on clear speed. With 240 maximum capacity and 1 point per 6 minutes regeneration, use naturally regenerated charge from overnight accumulation.
Top 5 Highest XP-Per-Hour Activities (Tested & Ranked)
Combat Simulations: Direct Senior Log rewards (3000 XP each). HIA Club simulations provide Advanced Stun Certification Seals and Pioneer's Certification Seals alongside logs.
Daily Errands: 1800 XP from 3 Official Logs in 10-15 minutes. Effective rate of 7200-10800 XP per hour measured by active engagement time.
Weekly Tasks: Substantial XP chunks but reset only once per seven days.
Season Tasks: One-time completion bonuses for initial progression.
Expansion Tasks: Progressive unlocks with supplemental XP.
Combat Simulations: Optimal Routes & Clear Times
HIA Club Combat Simulations offer highest concentration of Senior Logs per Battery Charge spent. Advanced difficulty tiers require stronger Agent rosters but deliver superior Certification Seal quality alongside identical log rewards.
Clear times vary by team composition:
- AOE-focused teams complete wave-based simulations 30-40% faster than single-target specialists
- Boss-oriented simulations favor concentrated damage dealers
Optimal routes prioritize simulations with shortest clear times relative to Battery Charge costs. Test 2-3 simulation types to identify personal efficiency peaks.
Daily Errands: Foundation of Consistent Progression
Four-task structure requires minimal combat engagement:
- Login confirmation
- Coffee purchase (also restores 60 Battery Charge)
- Newsstand scratch cards
- Video store visit
Coffee purchases serve dual purposes: completing errands for log rewards while restoring Battery Charge for Combat Simulation farming. Newsstand and video store require only interaction prompts without resource expenditure.
The 24-Hour Emergency Grinding Schedule
Emergency scenarios require maximizing every XP source within compressed timeframes. Server reset timing determines optimal session scheduling—begin immediately after daily reset to capture two Daily Errands cycles if deadline permits (3600 XP before Combat Simulations).
Battery Charge regeneration limits same-day farming capacity. With 240 maximum charge and 1 point per 6 minutes (10 per hour), gain 240 charge across 24 hours plus starting reserves. Coffee purchases add 60 charge per transaction.
Hour 0-6: Daily Reset Optimization (Morning Block)
Immediate Daily Errands completion secures 1800 XP within 15 minutes. Optimal sequence: Random Play → Coff Coffee → newsstand → video store.
Coffee purchase serves triple duty: completing errands, restoring 60 Battery Charge, providing caffeine item for subsequent purchases.
Remaining 5 hours 45 minutes focus on Combat Simulation farming. Starting with 240 maximum charge plus 60 from coffee (300 total), complete multiple simulation runs targeting Senior Logs.
Hour 6-12: Stamina Burn Phase (Midday Intensive)
Battery Charge regeneration restores approximately 60 additional points by hour 6. Combined with strategic Coffee purchases, maintain continuous Combat Simulation access.
Prioritize Senior Log acquisition through repeated HIA Club simulations. Each 3000 XP log significantly advances Level 50 progress. Identify fastest-clearing simulation type and repeat exclusively.
Set 60-minute timers to return for simulation runs as soon as sufficient charge accumulates.
Hour 12-18: Weekly Mission Completion (Evening Push)
If weekly reset timing aligns, complete Weekly Tasks during this block for supplemental XP. Avoid tasks consuming excessive time relative to XP rewards.
Battery Charge continues regenerating, adding another 60 points across 6 hours. Sufficient charge for 2-3 additional simulation runs yielding Senior Logs.
Hour 18-24: Final Sprint with Refills (Night Grind)
Final 6-hour block determines success. Calculate exact XP deficits and available Battery Charge to determine if additional Coffee purchases become necessary.
Players approaching second daily reset gain access to another Daily Errands cycle for 1800 XP. This second set of Official Logs often provides final push for Level 50.
Battery Charge management becomes critical. Approximately 60 points regenerate across this block—optimize simulation runs to extract maximum XP before 2026-02-02 03:59 deadline.
Energy & Stamina Management for Maximum Output
Battery Charge regenerates at fixed 1 point per 6 minutes regardless of player activity. 240-point maximum capacity represents 24 hours of natural regeneration.
Coffee purchases provide only renewable Battery Charge restoration: 60 charge per transaction. Players with substantial Dennie reserves bypass regeneration timers through repeated purchases.
Natural Stamina Regeneration Math
Battery Charge regenerates 10 points per hour:
- 8-hour sleep period: 80 charge
- 8-hour workday: 80 charge
- Daily passive generation: 160 points
240-point maximum cap prevents overflow waste. Log in twice daily—morning and evening—to capture full regeneration benefits.
Calculate exact regeneration timing by dividing desired charge by 10 points per hour. Needing 60 charge requires 6 hours regeneration from zero.
When to Use Battery Charges vs Polychrome Refills
Battery Charge expenditure should prioritize Senior Log acquisition. 3000 XP per log vastly exceeds alternative XP sources.
Polychrome refills serve emergency scenarios where Battery Charge depletion blocks critical progression. Players within 3000 XP of Level 50 during final hours may justify Polychrome expenditure for Coffee purchases.
Cost-benefit analysis favors natural regeneration for players with multiple days remaining. Spend premium currency only when time constraints prevent natural accumulation.
Stamina-to-XP Conversion Rates by Activity
- Combat Simulations: 3000 XP per 40-60 Battery Charge = 50-75 XP per charge point
- Daily Errands: 1800 XP for zero Battery Charge = infinite conversion efficiency
- Weekly/Season Tasks: Variable rates depending on objectives
Speed Team Compositions for Fastest Clears
Team composition directly impacts Combat Simulation clear times. AOE damage dealers excel in wave-based simulations, while single-target specialists dominate boss-focused challenges.
Stun-focused teams leverage Advanced Stun Certification Seal rewards, creating synergy between farming objectives and team building. Rapid stun accumulation reduces enemy action windows.
Support characters that enhance team damage provide multiplicative benefits. Attack buffs, defense shreds, and elemental resistance reductions amplify primary damage dealers.
AOE Burst Teams for Combat Commissions
Multi-target simulations reward characters with wide-area ultimate abilities. Teams built around AOE burst damage eliminate entire enemy waves simultaneously.
Energy regeneration speed determines ultimate frequency. Characters with low energy costs or rapid energy gain enable more frequent burst windows. Pair with energy-generating supports for maximum ultimate uptime.
Group enemies before unleashing area abilities for maximum hit counts per skill activation.
Single-Target DPS for Boss Simulations
Boss-oriented simulations favor concentrated damage against single high-health targets. Characters with sustained DPS or powerful single-target ultimates outperform AOE specialists.
Coordinate stun accumulation with damage dealer burst windows, maximizing damage during vulnerability phases. This reduces total rotation cycles needed for boss elimination.
Defensive utility prevents team wipes that force simulation restarts, protecting Battery Charge investments.
Common XP Farming Mistakes That Waste Time
Inefficient activity prioritization: Engaging with low-XP tasks before exhausting high-efficiency sources like Daily Errands and Combat Simulations.
Battery Charge overflow: Reaching 240 maximum capacity while charge continues regenerating represents lost XP opportunities.
Incomplete Daily Errands: Minimal 10-15 minute investment for 1800 XP creates highest return-on-time in entire progression system.
Misconception: All Missions Give Equal XP Per Minute
XP acquisition rates vary dramatically. Combat Simulations yield 3000 XP in 5-10 minutes, while certain exploration tasks grant 100 XP for 15-20 minute investments—a 30:1 efficiency gap.
Players often overvalue task variety, attempting to complete every available objective rather than focusing on highest-efficiency activities.
Sequence tasks by XP-per-minute rates rather than arbitrary reset timers.
Avoiding Low-Efficiency Story Replays
Story mission replays provide minimal City Fund XP. XP differential between story replays and Combat Simulations often exceeds 10:1 ratios. A 20-minute story mission might grant 300 XP, while same timeframe enables 2-3 simulation runs yielding 6000-9000 XP.
Reserve story engagement for enjoyment rather than XP farming.
Stamina Overflow Prevention
Check current charge levels every 4-6 hours, ensuring timely Combat Simulation engagement before reaching 240 maximum capacity.
Set mobile reminders for charge depletion every 6 hours. Buy coffee at 0-60 charge to maximize total available charge—purchasing at 180/240 wastes 60 points of natural regeneration.
Last-Minute Optimization: The Final 500 XP Push
500 XP deficit requires only one Trainee Log (100 XP) plus partial Daily Errands completion, or approximately 17% of one Official Log's value.
Verify exact current XP total before final farming sessions. City Fund interface sometimes displays level progress bars that lag behind actual accumulated XP.
Target Level 50 completion 2-3 hours before 2026-02-02 03:59 cutoff for buffer time.
Quick Win Missions Under 5 Minutes
Certain Combat Simulations feature simplified enemy compositions that capable teams eliminate in under 3 minutes. Identify these quick-clear simulations for rapid Senior Log acquisition.
Daily Errands represent ultimate quick-win activity: 10-15 minute investment for 1800 XP.
Low-difficulty simulations sacrifice Certification Seal quality but maintain identical Investigator Log rewards. Select minimum difficulty tiers for 2-3 minute clears.
