ZZZ 3.3 New Eridu City Fund Guide: Growth or Premium, 888 Polychrome, and Phoenix Budget

The Version 3.3 New Eridu City Fund is live, and the choice is more nuanced than “paid pass or free pass.” The Basic Plan costs nothing. The Growth Plan opens the paid level track and gives 680 Polychrome immediately. The Premium Plan adds 208 more Polychrome, a limited menu decoration set, and several upgrade items. Those instant rewards are useful, but the real value still depends on how many Fund levels you expect to finish before the season closes.

Version 3.3 also arrives with Phoenix and Velina in Phase I, two featured W-Engines, new Phoenix outfits, and a long list of event rewards. That makes it easy to count the same currency twice or buy a higher plan simply because the 888 Polychrome total sounds large. This guide separates the plans, converts the currency into pulls, explains the Level 30 W-Engine choice, and shows where the City Fund fits in a realistic Phoenix or Velina budget.

What the Version 3.3 New Eridu City Fund includes

Every eligible account automatically receives the Basic Plan. Completing Expansion Tasks raises the City Fund level and unlocks the free-track rewards. The Growth Plan opens the paid rewards for every level reached and immediately grants 680 Polychrome plus the exclusive “Trick or Treat!” avatar. If you buy it after progressing the free track, the paid rewards for completed levels unlock retroactively.

The Premium Plan includes the Growth Plan benefits and adds an immediate 208 Polychrome, the “Night of Tricks” menu decoration set, a W-Engine Microcontroller Unit, a Resonating Core, and Ether Batteries. Players who already purchased Growth can use Plan Upgrade instead of buying a second pass. Premium is therefore an upgrade layer, not a separate reward track that can be collected twice.

Event duration, purchase cutoff, and unlock requirement

According to the official Version 3.3 City Fund notice, the season runs from the Version 3.3 update until November 30, 2026 at 03:59 server time. Growth Plan, Premium Plan, and Plan Upgrade purchases close one hour earlier, at 02:59 server time. The final hour is for finishing available tasks and claiming rewards; it is not an extra hour in which to purchase or upgrade.

The City Fund becomes available after unlocking Combat Simulation in Main Story Chapter 1, “Cat's Lost & Found.” Because the notice uses server time, the countdown inside your own game is the safest reference. Do not replace it with one universal Beijing-time conversion for every region, and do not wait until the last few minutes if a platform payment check may be required.

Basic, Growth, or Premium: which plan fits your account

Basic is enough for players who mainly want event currency and routine materials without paying. Growth is the practical middle choice for an active player who expects to complete a good portion of the level track. It combines 680 immediate Polychrome with the paid materials and the Level 30 certificate, so its value increases sharply when the account is already progressing consistently.

Premium makes most sense when you genuinely want the limited menu decoration and value the extra upgrade materials alongside the additional 208 Polychrome. It is not automatically the “best value” for every player. Regional and platform prices may differ, and the official notice does not publish one universal cash price, so compare the live amount in your own client with the rewards you will actually use.

How many pulls are 680, 208, and 888 Polychrome

One Signal Search costs 160 Polychrome. The Growth Plan's 680 Polychrome covers four pulls with 40 left. Premium's additional 208 covers one pull with 48 left. If you obtain the full Premium route, the two instant amounts total 888 Polychrome, equal to five pulls with 88 left. This is a helpful boost, but nowhere close to a guaranteed S-Rank by itself.

Keep the arithmetic honest. The 208 is additional to the Growth benefits; it is not a second 680 reward. The Polychrome is granted immediately when the relevant plan is unlocked, while most materials remain tied to Fund levels. When comparing the plans, separate “currency received today” from “rewards collected only after completing tasks.”

Fund levels, retroactive rewards, and the Level 30 checkpoint

City Fund purchases unlock paid rewards for levels you have already completed, which means you do not have to buy on day one. Waiting until your progress is clearer can be sensible, especially if your play schedule is uncertain. The trade-off is that waiting too long leaves less time to notice missed tasks, resolve a payment issue, or use the time-limited certificate.

Level 30 is the most important checkpoint because it unlocks the Great Builder's Certificate for Growth and Premium owners. The certificate does not carry into the next City Fund period and expires if unused. Claiming it from the track is only the first step: open the selection and choose a W-Engine before the season ends.

Choosing Bloodmarrow Coffer or another A-Rank W-Engine

At Level 30, the Great Builder's Certificate lets you choose one of seven A-Rank W-Engines, including Bloodmarrow Coffer for Armorer Agents. The other available choices cover different specialties, so “pick the newest one” is not a reliable rule. Look at the Agents you actively use, their current W-Engines, and whether another copy meaningfully improves a refinement level.

Bloodmarrow Coffer is a sensible choice when an Armorer Agent needs an accessible A-Rank option and your account lacks a better alternative. If a core Attack, Support, Stun, Anomaly, or Defense Agent is still using a weak engine, an older certificate option may improve the account more immediately. The certificate is valuable because it solves a real equipment gap, not because one item has the newest label.

Growth Plan vs Premium Plan for Phoenix and Velina players

Phoenix and Velina are both Anomaly Agents in the Phase I Exclusive Channels, while Plume of Rebirth and Joyau Dore appear in the W-Engine Channels. Agent-channel pity is separate from W-Engine pity. Before using City Fund Polychrome, record your current Agent pity, whether the next S-Rank is guaranteed, available Encrypted Master Tapes, and the closing time shown on your server.

For a limited budget, use the City Fund to support one clear target. Five extra pulls can close a small gap, but they should not turn into permission to chase Phoenix, Velina, a signature W-Engine, and cosmetics at once. Try the Agents, decide which roster problem you are solving, and reserve currency for that goal before considering a W-Engine channel.

Building a Polychrome and Monochrome budget without double counting

Start with resources already on the account: Polychrome, Encrypted Master Tapes, and current pity. Add only confirmed rewards you can earn before the target channel closes. Then add 680 Polychrome if you are buying Growth, or 888 total if you are taking the full Premium route. Do not count an unpurchased plan, unfinished event, or future mail as money already available.

If a shortfall remains, check the current package size, final price, region, server, and account details on the Treabar Zenless Zone Zero top-up page. Monochrome can be converted to Polychrome at 1:1, but first-purchase bonuses and package offers must be checked live. Choose a package only after calculating the actual gap, and never provide an account password for a normal UID-based top-up.

The practical recommendation for Version 3.3

Stay with Basic if your playtime is uncertain or the paid materials do not solve a current need. Choose Growth when you expect to reach at least Level 30 and want the strongest balance of instant Polychrome, paid-track materials, and a selectable A-Rank W-Engine. Upgrade to Premium when the limited decoration, extra materials, and 208 additional Polychrome are worth the displayed regional price to you.

There is no need to decide purely from launch-day excitement. Check your progress again after several weeks, but leave a comfortable margin before the November 30 purchase cutoff. Whichever plan you choose, claim every unlocked tier and use the Great Builder's Certificate before it expires. The City Fund is most useful as part of a measured pull plan, not as a substitute for knowing your pity and spending limit.
