Zenless Zone Zero New Eridu City Fund Battle Pass Guide

The New Eridu City Fund, Zenless Zone Zero's Battle Pass, is unlocked after completing the Explosive Last Train mission in Chapter 1 of ZZZ. You will likely be around Inter-Knot Level 10 when reaching this mission. Once completed, you will be able unlock and use the Battle Pass.

The Battle Pass provides a variety of daily, weekly and patch-length tasks that you can complete to earn Battle Pass XP in order to obtain a range of rewards that help you upgrade and progress your characters level, skills and equipment. You will also be able to claim Polychrome, Tapes and Master Tapes to pull for more characters!

The Battle Pass has 60 levels, each requiring 1000 XP to reach the next level meaning a total of 60,000 XP is required to complete the Battle Pass. The Battle Pass lasts for the duration of the patch and is then replaced with a new Pass with the beginning of the next patch. You are limited to 10.000 XP per week from your daily and weekly tasks.

There are 2 variations of the Battle Pass with the Basic Plan on the top, which every play can access for free, and the Growth Plan at the bottom, which is the paid version. The Growth Plan typically offers higher tier versions of each level's rewards, i.e. granting A-Rank instead of B-Rank Agent experience materials.

It also offers Tactical Chips that can be used to enhance Skills of Agents, regardless of Element, provides Master Tapes where the Basic Plan only offers Standard Tapes for pulling new Agents, and grants a Battle Pass A-Rank W-Engine that can only be acquired through the Battle Pass.

The Growth Plan has two variations: You can either buy the regular Growth Plan, which grants you all the rewards of the Growth Plan itself, or the Premium Plan, which immediately adds 10 Levels to your Battle Pass while also granting some cosmetic benefits like a character profile picture, some extra Ether Batteries, 200 Polychrome and a Lucky Scratcher for Howl in Sixth Street.

The 10 levels given by the Premium Plan are not even remotely needed to fully max out the Battle Pass, provided you play regularly to complete your tasks and hit your 10.000 weekly XP limit. Therefore, your choice should depend on if you personally like the exclusive profile picture or Namecard.

You also do not need to buy either to progress in the game. While the exclusive W-Engines are nice and some can be very useful, they are not needed or mandatory in any way. The character, skill upgrade, and leveling materials are very helpful as they allow you to spend your daily Battery Charge on other things instead, but you can progress at your own pace without relying on the Battle Pass.

While all of the Battlepass W-Engines provide unique bonuses, some of these are more useful than others. You should always look at your account and see if any of the weapons provide particularly useful benefits to you now, and long-term. Battlepass weapons take a long time to upgrade to max-rank, since you can only acquire one of them each Battlepass, and you need 5 copies for the maximum effect.

That being said, most players will likely end up wanting to get either the Rupture, Anomaly, or Support W-Engines.

Unfettered Game Ball, the Support W-Engine, is the potential top pick, if you can make use of it. It provides additional Energy Regen which will allow you to build up to more Quick Assists faster, but many other Support W-Engines do this too. However, this W-Engine also provides a very significant CRIT Rate increase as a debuff to any enemy you hit with an Attribute Counter. This will greatly boost the damage of your Attack Agents, and makes it a very future-proof W-Engine. The downside is that this major benefit will only be available to you when your Support is up against Attribute Weaknesses. With how static some team compositions are, you are unlikely to benefit from this for all fights, especially in endgame content.

Radiowave Journey, the Rupture W-Engine from the Battlepass, is the only A-Rank W-Engine in Patch 2.0 that provides HP as an Advanced Stat increase. This W-Engine only has use for one Agent at the time of this writing, Yixuan, and even at R51 this W-Engine is better than a fully enhanced R5 Puzzle Sphere that you can craft at the Gadget Store. If you pulled for Yixuan, this is worth picking up at least once, and we might see more HP scaling Rupture Agents in the future too!

Electro-Lip Gloss is the last high-value W-Engine, and will be a very useful W-Engine for any Anomaly Agent. With its Anomaly Proficiency bonus, and a passive that boosts both ATK % and DMG %, it will greatly increase the damage of your Anomaly and Disorder triggers. With multiple copies of this, it is a very strong alternative to all A-Rank Anomaly W-Engines, and at R5 it typically outperforms the best crafted W-Engine option, Weeping Gemini.

The remaining two W-Engines are not nearly as useful, as the game does not have a whole lot of Defense Agents that scale with Defense. The Stun W-Engine takes a long time to get its full effectiveness charged up without providing any unique Advanced Stat bonuses compared to F2P alternatives, while the Attack W-Engine has too many alternatives to be worth considering, especially with how strong the crafted Attack W-Engine is.

There are a range of daily, weekly and patch-based challenges you can complete to level up the New Eridu City Fund. There is a weekly cap of 10,000 XP meaning you can only level 10 levels at most in a week, but the Season Tasks do not count towards this cap. Some Season Tasks are tied to Events and are therefore unobtainable once the Event is over.

Listed below is a collection of Battle Pass tasks, how much XP they provide, as well as some advice on completing them.

Season Tasks:

Season Tasks are patch-based, and occasionally some are added halfway through the patch as well, as they often revolve around progressing through certain limited time events. XP gained through season tasks ignores the weekly XP limit. The below list is not exhaustive and only lists the permanent tasks, as many other these tasks are only available for the duration of limited-time events.
