Is the ZZZ 3.2 New Eridu City Fund Worth Buying Before It Ends?
The Version 3.2 New Eridu City Fund is almost over, but its two deadlines are not the same. Purchases of the Growth Plan, Premium Plan, and Plan Upgrade close on October 19 at 02:59 server time. The Fund remains open for one more hour, until 03:59 server time, so players who already paid can finish available tasks and claim rewards. Waiting for the final hour to buy is therefore a mistake: the purchase button disappears before the reward screen closes.
Whether it is worth paying now depends less on the headline Polychrome and more on the Fund level already reached. A player at Level 50 is buying a completed reward track. A player far below Level 30 may be paying for rewards that cannot realistically be unlocked before the claim deadline. This guide separates the instant currency, the level-based rewards, the Level 30 W-Engine choice, and the Monochrome budget for Version 3.3 so that the decision is based on what your account can still collect.

The exact City Fund purchase and claim deadlines
HoYoverse's Version 3.2 New Eridu City Fund notice sets the purchase deadline at October 19, 02:59 server time. The event and reward-claim period end at October 19, 03:59 server time. These are server-time deadlines, not one universal clock conversion for every region. The countdown shown inside your own game is the safest final reference.
That one-hour gap is useful only after a plan has been purchased. It gives existing buyers a short final window to complete any remaining Expansion Tasks and collect unlocked rewards; it does not extend the time for buying or upgrading the plan. Before spending, open the City Fund page, confirm the current level, inspect every unclaimed tier, and check whether the required tasks can still be completed.
The City Fund also ends before Version 3.2 itself. The 3.2 update announcement lists the version ending on October 21 at 06:00 UTC+8. Do not assume that every 3.2 feature remains available until maintenance; individual events have their own clocks.
Basic Plan, Growth Plan, and Premium Plan compared
The Basic Plan is unlocked automatically and costs nothing. Buying the Growth Plan opens the paid reward track and immediately grants 680 Polychrome plus the exclusive avatar Where the Waves Begin. Buying the Premium Plan adds the Growth Plan benefits and provides another 208 Polychrome, a menu decoration set, a W-Engine Microcontroller Unit, a Resonating Core, and Ether Batteries. Players who already own the Growth Plan can use Plan Upgrade to move to Premium.
The practical difference is simple. Growth Plan carries most of the value tied to the paid level track. Premium Plan is an optional upgrade for players who care about the cosmetics, extra upgrade materials, and 208 additional Polychrome. It should not be described as a second full battle pass, and the extra 208 Polychrome alone is not enough reason to upgrade if the other bonuses do not matter to you.
Prices can differ by platform and region, so compare the amount shown in your own client. Also check whether platform wallet balance or payment restrictions apply before the purchase deadline. The City Fund is an in-game plan; a separate Monochrome top-up does not automatically unlock it.
Your current Fund level matters more than the instant Polychrome
At a high Fund level with most paid tiers ready to claim, the decision is straightforward: the purchase retroactively unlocks the paid rewards for levels already completed. At Level 30 or above, it also makes the Great Builder's Certificate obtainable, provided you claim it in time. At a lower level, count the Expansion Tasks still available and calculate the Fund EXP they can actually provide before 03:59 server time.
Do not buy on the assumption that a future login will finish the track. There is no next-day recovery after the event closes. If the account cannot reach the reward tier you value, judge the purchase only by the instant Polychrome and the lower tiers already secured. Likewise, do not pay merely because the progress bar is close to a round number; check the actual rewards behind that number.
A useful rule is to divide the decision into three states. Level 50 or a nearly complete track offers the clearest total value. Level 30 to 49 can still be attractive because the selectable W-Engine and many paid materials are available. Below Level 30 requires caution: verify whether enough tasks remain to reach the certificate before treating it as part of the purchase.
What 680 and 208 Polychrome mean for Version 3.3
One Signal Search costs 160 Polychrome. The Growth Plan's 680 Polychrome equals four searches with 40 Polychrome left. The Premium upgrade's extra 208 equals one search with 48 left. Together, 888 Polychrome equals five searches with 88 left. This is helpful, but it is not a guarantee for Phoenix or any other S-Rank Agent.
Version 3.3 launches on October 21, and HoYoverse has confirmed Phoenix in the first phase. Before buying anything, record your current Exclusive Channel search count, whether the next S-Rank is guaranteed, the Encrypted Master Tapes already owned, and the Polychrome you can still earn. Then add only the City Fund currency you are certain to receive. This prevents five extra searches from being mistaken for a complete pull plan.
Keep Agent and W-Engine budgets separate. If Phoenix is the main target, reserve enough for the Agent before considering her signature W-Engine. The safest spending decision is based on the remaining number of searches to a conservative guarantee, not on the visual size of a currency bundle.
Choosing Bloodmarrow Coffer or another A-Rank W-Engine
After unlocking Growth or Premium and reaching City Fund Level 30, players can claim a Great Builder's Certificate and choose one of seven A-Rank W-Engines: Bloodmarrow Coffer, Radiowave Journey, Cannon Rotor, Six Shooter, Electro-Lip Gloss, Unfettered Game Ball, or Spring Embrace. Bloodmarrow Coffer is the new Armorer option introduced in Version 3.2, but “new” does not automatically mean “best for every account.”
Choose for a character you use or intend to build. Bloodmarrow Coffer has clear relevance when an Armorer Agent needs an accessible A-Rank option. If your established team urgently needs a W-Engine for another specialty, one of the older choices can produce more immediate account value. Check the equipped alternatives, refinement level, and whether another copy would meaningfully improve an existing weapon before selecting.
Most importantly, the certificate is time-limited. HoYoverse states that it does not carry into the next City Fund and expires if unused. Claiming the certificate is not the final step; open it and complete the W-Engine selection before the event closes.
Other Version 3.2 tasks ending around the same window
October 19 is also the listed end date for Clink, Clank, Pinball Knight!, Diary of an Orbie Parent, Chronicles of the Hobbling Crow, and the Combat Simulation double-reward event. Check each event page for its own entry requirements and server-time countdown. Use any remaining Battery Charge on the double-drop stages only if the materials match your current build plan.
Several rewards last longer, so do not mix every deadline together. The All-New Program login reward, Surprise Screening Plan, and “En-Nah” Into Your Lap run until October 20 at 03:59 server time. Angels Support Operation lasts beyond the version transition. A clean final checklist is better than trying to finish content in the order it appears on the event menu.
Prioritize irreversible losses: buy or upgrade the City Fund before 02:59 if you have decided it is worthwhile; claim the Fund and use the certificate before 03:59; finish same-day events; then collect the login rewards that remain available until October 20.
How to calculate a Monochrome top-up without overspending
First calculate the pull shortfall after free resources. Convert current Polychrome at 160 per search, add Encrypted Master Tapes, confirmed event rewards, and the City Fund amount you will actually receive. Subtract that total from the conservative number of searches needed for the target. Do not include future rewards you may not have time to finish.
If a shortfall remains, check current denominations, final checkout price, first-purchase bonus status, and supported server on the Treabar Zenless Zone Zero top-up page. Monochrome converts to Polychrome at a 1:1 rate, but package bonuses and prices can change, so use the live checkout rather than an old screenshot. Choose the smallest package that covers the verified gap and leaves a modest buffer.
Confirm the UID and server before payment. A normal UID top-up should not require an account password. City Fund value and Monochrome value should be evaluated separately: one unlocks a level-based reward track, while the other fills a direct currency shortage.
The final recommendation before October 19
Buy the Growth Plan when the account has already completed enough of the track to make the paid materials useful, especially at Level 30 or above. Consider Premium only when the extra cosmetics, upgrade items, and 208 Polychrome are worth the regional price to you. Skip the purchase when the account is too low to reach the important tiers and the instant currency alone does not justify the cost.
Before closing the menu, claim every unlocked tier and spend the Great Builder's Certificate. Then rebuild the Version 3.3 budget from the actual balance on the account. The City Fund can improve a Phoenix plan, but its strongest value comes from combining currency with materials and the selectable W-Engine, not from pretending that 888 Polychrome solves an entire limited-banner guarantee.

FAQ
When does the ZZZ 3.2 New Eridu City Fund purchase close?
Growth Plan, Premium Plan, and Plan Upgrade purchases close on October 19 at 02:59 server time. The event and reward claims close one hour later at 03:59 server time.
How much Polychrome do Growth and Premium provide?
Growth Plan grants 680 Polychrome immediately. Premium Plan adds another 208, making 888 in total for players who obtain the full Premium benefits.
Can I still get Bloodmarrow Coffer below City Fund Level 30?
No. You must unlock Growth or Premium, reach Level 30, claim the Great Builder's Certificate, and use it to select Bloodmarrow Coffer or another available A-Rank W-Engine.
Does the Great Builder's Certificate carry into Version 3.3?
No. It is limited to the current City Fund period and expires if it is not used before the deadline.
Should I buy City Fund or top up Monochrome for Phoenix?
They solve different needs. City Fund is strongest when much of its level track is already complete; Monochrome directly covers a verified pull shortfall. Calculate your pity, tapes, Polychrome, and remaining free rewards before choosing either.
