Proxies diving into New Eridu this season are in for a treat. The New Eridu City Fund has returned with its Version 3.1 update, transforming routine dailies and missions into a cascade of rewards that feels like discovering a hidden pantry stocked with favorite delicacies. Before anyone even realizes it, the City Fund operates like a silent elevator in a skyscraper—each floor opened brings a better view and a tangible boost to a Proxy's arsenal.

At its core, the event invites players to earn generous rewards simply by raising their City Fund Level. The Foundation Plan unlocks automatically at the beginning of each season, requiring no payment, and expands through Expansion Tasks that grant experience. Think of the City Fund as a bonsai tree that grows richer foliage with each careful pruning—every completed task nurtures the progression, and the higher the level, the more lush the reward harvest becomes.

But the real gold lies in the paid tiers. By unlocking the Growth Plan, a Proxy immediately receives 680 Polychrome and the exclusive avatar \u201cBerry Party.\u201d This isn\u2019t just a cosmetic trinket—it\u2019s a badge of dedication, like a tailor-made suit that signals one\u2019s commitment in the city\u2019s chaotic fashion scene. For those who want to sprint ahead, the Premium Plan offers instant rewards as soon as it is unlocked: 208 Polychrome, a menu decoration set, a W-Engine Microcontroller Unit, a Resonating Core, and Ether Batteries. It\u2019s a starter kit that feels like being handed a master key to a locked library of power-ups.

Progression through the City Fund levels is where the layered incentives shine. Once a Growth Plan or Premium Plan is active, reaching certain milestones unlocks exclusive namecards like \u201cTime for Afternoon Tea,\u201d additional W-Engine Microcontroller Units, Resonating Cores, Hamster Cage Passes, and various upgrade materials. A unique twist: Proxies can even select their preferred type of upgrade materials, ensuring the rewards don\u2019t just pile up as generic currency but actually fit the character builds they\u2019re nurturing. This is akin to a chef being allowed to hand-pick the spices for the next signature dish rather than being given a standard seasoning packet.

Timing is everything. The event runs from the Version 3.1 update until September 7, 2026, at 03:59 (server time). However, the purchasing window for the Growth Plan, Premium Plan, and Plan Upgrade closes a little earlier, on September 7, 2026, at 02:59 (server time). After purchasing closes, Expansion Tasks can still be completed and rewards claimed, but planning ahead is wise. For those who missed the initial unlock, the Basic Plan is automatically active once Combat Simulation in Main Story Chapter 1 \u201cCat\u2019s Lost & Found\u201d is unlocked—meaning even newcomers can ride this generous wave.

A particularly juicy detail sits at the summit of this reward ladder. When a Proxy reaches City Fund Level 30 with a Growth Plan or Premium Plan active, they can claim the Great Builder\u2019s Certificate. This is not a permanent keepsake but a time-limited reward for the current City Fund period. It must be used before it expires; it won\u2019t carry over to the next season, making it akin to a golden ticket that vanishes if not redeemed in time.

Upgrading from Growth Plan to Premium Plan is also made seamless through the Plan Upgrade option—no need to repurchase the entire bundle. This flexibility ensures that Proxies can taste the lower tier and, if the hunger for polychromes and exclusive goodies strikes, leap upward without wasted resources.

The New Eridu City Fund is more than a battle pass. It\u2019s a symbiotic cycle where regular play, daily logins, and task completions pay off in a compounding loop of instant gratification and long-term gains. In a city where every Polychrome and upgrade material counts toward pulling the next S-Rank Agent, the City Fund acts like a reliable battery, steadily charging a Proxy\u2019s progress with each season.

For Proxies still on the fence, think of the Berry Party avatar and the afternoon tea namecard as small trophies that whisper \u201cI was there\u201d long after the season ends. The plan\u2019s design ensures that both casual explorers and min-maxing theorycrafters find compelling value. The City Fund doesn\u2019t just reward gameplay—it reshapes it, turning the daily grind into a treasure hunt with clearly marked X\u2019s on the map.

With Version 3.1\u2019s season still fresh, now is the perfect moment to jump in, complete those Expansion Tasks, and watch the Fund Level climb. Just keep an eye on that September cutoff—the Great Builder\u2019s Certificate won\u2019t wait, and neither will the exclusive namecard that adds a touch of afternoon elegance to any Proxy profile.
