How the City Fund Works: Plans, Upgrades & Rewards
All players begin with the Basic Plan for free. By completing Expansion Tasks—available throughout New Eridu—you accrue Fund Level XP and unlock tiered rewards.
- Growth Plan: Offers extra rewards for a one-time fee.
- Premium Plan: Includes all Growth Plan rewards, plus the Sweet Dreams in the Breeze avatar and Upon a Pillow of Clouds namecard.
- Upgrade Flexibility: Players who bought the Growth Plan can upgrade to Premium mid-season, keeping all accrued progress.
Reaching City Fund Level 30 unlocks the Great Builder's Certificate: a limited-use item for the current period only. Unused certificates expire automatically—plan usage accordingly.
Key Rewards Comparison
| Reward Tier | Free Plan (Basic) | Growth Plan | Premium Plan |
|---|---|---|---|
| Master Tapes | Yes (standard amount) | More (Encrypted) | Most + exclusive items |
| A-Rank W-Eg. | No | Yes (Selectable) | Yes (Selectable) |
| Skins | No | No | Yes (Avatar, Namecard) |
| Certif. | No | Yes (at Lv. 30) | Yes (at Lv. 30) |
F2P and Spender Strategy: Who Should Upgrade?
For F2P & Low-Spenders:
– Free Basic Plan still delivers some Master Tapes and upgrade fodder.
– Evaluate if the A-Rank W-Engine (choice) fills a gear gap; if not, consider saving for a future cycle.
– Premium cosmetic rewards have no gameplay impact—acquire only for collector’s sake.
Optimizers & Heavy Spenders:
– Calculate real-world currency cost per Encrypted Master Tape versus direct gacha purchase.
– Prioritize Premium Plan only if you value unique cosmetics and want to ensure all rare resource drops.
– Remember, timed rewards and certificates do not roll over—use before expiration.
Best Practices: Getting the Most from the City Fund
- Complete Expansion Tasks Daily: Don’t let XP go uncollected; progress towards Fund Levels steadily.
- Purchase/Upgrade Early: Maximize time spent with premium rewards active—late purchases forfeit prior high-tier unlocks.
- Monitor Event Timers: Purchases close one hour before event end; finish tasks and claims slightly ahead.
- Select Your W-Engine Wisely: Match selection to current roster needs or future meta shifts (see EarlyGG’s upcoming W-Engine tier list).
- Great Builder’s Certificate: Use as soon as eligible to prevent expiration waste.
Event Rewards: Highlights & Milestones
- Encrypted Master Tapes: For premium banner pulls—essential for limited units.
- Selectable A-Rank W-Engine: Direct boost for any character’s loadout; eliminates poor RNG risk.
- Cosmetics: Avatars and namecards for premium spenders—showcase event participation.
- Standard Ascension Materials: Scattered throughout all plans, useful for daily progression.
