How the New Eridu City Fund Works
At the start of each season, the Basic Plan is automatically unlocked for all Proxies. You earn experience by completing Expansion Tasks, which raises your City Fund Level and unlocks rewards along the track. The free tier includes standard materials and Polychrome, but the premium tiers add exclusive items.
Unlocking the Growth Plan instantly grants Polychrome ×680 and the exclusive avatar Where the Waves Begin. The Premium Plan adds Polychrome ×208, a menu decoration set, the W-Engine Microcontroller Unit, Resonating Core, and Ether Batteries as instant rewards.
As you level up, both paid plans also grant the exclusive namecard Before Returning to the Sea, additional W-Engine Microcontroller Units, Resonating Cores, Hamster Cage Passes, and upgrade materials. Notably, you can choose the type of upgrade materials you receive, which is a small but welcome quality-of-life improvement for targeted farming.
The New W-Engine: Bloodmarrow Coffer
The standout addition this season is the A-Rank W-Engine Bloodmarrow Coffer, designed for Armorer Agents. To claim it, you must unlock the Growth Plan or Premium Plan, reach City Fund Level Lv. 30, and collect the Great Builder's Certificate. This certificate is a time-limited reward—it won’t carry over to the next City Fund period and expires if unused.
Once you have the certificate, you can choose one of seven W-Engines, including the Bloodmarrow Coffer. This gives you flexibility if you already own some of the other options, but the new engine is clearly the main draw for Armorer-focused players.
Should You Buy the Growth or Premium Plan?
For F2P players, the free Basic Plan still provides useful materials and Polychrome, but the premium tracks are where the real value lies. The Growth Plan is the most cost-effective way to secure the exclusive avatar and the bulk of the premium rewards, including the Bloodmarrow Coffer.
The Premium Plan adds extra Polychrome and a few convenience items, but the difference between Growth and Premium is smaller than the jump from free to paid. If you’re on a budget, the Growth Plan is the sweet spot. If you’re a collector or need the extra Ether Batteries for rapid progression, the Premium Plan may be worth the upgrade.
Remember that purchases close on 2026-10-19 02:59 (server time)—an hour before the event ends—so don’t wait until the last minute.
Pre-Patch To-Dos
Before the Version 3.2 update arrives, make sure you’ve completed any outstanding tasks from the current season. If you’re planning to buy the Growth Plan, ensure you have enough time to reach City Fund Level Lv. 30 to claim the Great Builder's Certificate. The event period is roughly six weeks, which is usually enough for dedicated players, but casual players should start early.
Also, check your current inventory of upgrade materials. The City Fund’s selectable rewards can help fill gaps, so plan which materials you need most.
Day-1 Priorities
After the update goes live, head straight to the New Eridu City Fund menu to review the reward track. If you’re buying the Growth Plan, do it early to start earning experience from day one. Complete your first batch of Expansion Tasks to get a head start on leveling.
If you’re aiming for the Bloodmarrow Coffer, prioritize reaching Lv. 30 as soon as possible. The certificate is time-limited, so don’t leave it to the last week.
Final Thoughts
The New Eridu City Fund remains one of the most consistent value sources in Zenless Zone Zero, and the Version 3.2 iteration adds a meaningful new W-Engine to the mix. For F2P players, the free track still offers solid rewards, but the Growth Plan is a clear upgrade if you’re willing to spend a little. Just keep an eye on the purchase deadline and plan your leveling accordingly.
