Breaking Down the City Fund: Plans, Tasks, and Rewards
Plan Tiers Explained
Every player is automatically enrolled in the Basic Plan at the start of each season, earning standard rewards for completing Expansion Tasks. This tier is especially appealing for F2P and low-spend players. However, HoYoverse’s offer of a dual-layered premium pass aligns closely with trendsetting monetization from titles like Genshin Impact’s Battle Pass or Honkai: Star Rail’s Nameless Honor.
- Growth Plan: Instantly gives Polychrome ×680 plus the exclusive avatar. This is a straightforward jump in value for moderate spenders.
- Premium Plan: Adds an extra Polychrome ×208, a menu decoration set, and expanded materials (including W-Engine Microcontroller Unit, Resonating Core, Ether Batteries).
Pro tip: Already bought Growth but want Premium? Purchase the "Plan Upgrade" to catch up—no lost rewards.

| Plan | Cost | Instant Polychrome | Avatars/Cosmetics | Materials & Extras |
|---|---|---|---|---|
| Basic (Free) | — | — | — | Standard upgrade materials |
| Growth Plan | Premium | ×680 | Exclusive Fan Support | Menu decor, W-Engine Microcontroller Unit, Resonating Core, Ether Batteries |

Not stated in official materials: precise purchase pricing, highest possible City Fund Level, or details on reward expiration beyond the Great Builder’s Certificate.
Should You Purchase or Upgrade?
For seasoned gacha players, the Polychrome bonus can sway calculations on optimal event spending. The total instant premium Polychrome is a notable boost—comparable to several multi-pulls—but the value for F2P players lies mainly in completion tasks and steady progression.
- F2P/Low-Spend: Basic Plan remains sufficient if you’re focused on long-term farming or saving for future banners. Compulsive upgraders should carefully gauge what units or gear are featured elsewhere this cycle.
- Optimal Value: Growth Plan offers good currency per dollar if you’re chasing avatars or need Polychrome now, while Premium is only worth it for completionists or meta-chasing Proxies.
Long-Term Implications
This structure closely mirrors other gacha season pass models—but the flexibility to select upgrade materials is a notable touch for minimizing wasted resources. Repeat engagement will depend on upcoming event synergies, like Shop rotations or limited-edition cosmetics attached to future City Funds.

Final Thoughts: City Fund as a Long-Term Feature

Key Takeaway: Prioritize task completion and claim all attainable rewards, but only upgrade if the material choice and avatars fill a real gap in your account. Keep an eye on server time windows—missing a purchase or claim deadline is an error even veteran gacha players regret.
