The New Eridu City Fund returns in Zenless Zone Zero 3.3 on three tracks. Basic is free and unlocked automatically from the start of the season; Growth is the paid track; Premium includes Growth plus a set of instant extras. Expansion Tasks and the free track stay open to everyone, but buying a plan or upgrading one closes an hour before the event ends.
Growth grants 680 Polychromes and the Trick or Treat! avatar immediately, then adds the Horror Tale: Childhood Edition namecard and upgrade materials as your Fund Level rises. Premium stacks 208 more Polychromes, a menu decoration set, a W-Engine Microcontroller Unit, a Resonating Core and Ether Batteries on top.
The reward easiest to overlook is the Great Builder’s Certificate. Reach Fund Level 30, claim it, and pick one W-Engine from a selection of seven, the A-Rank Bloodmarrow Coffer among them. It belongs to this Fund period: unused, it expires with the season.
For value, Growth is the buy for players who will actually finish the track. Premium only pays if the cosmetics and materials matter to you as well; if it is Polychromes alone, compare the package against buying currency directly.
Monochrome tiers in USD are listed on our Zenless Zone Zero page.
