Event Details

The New Eridu City Fund is a seasonal progression system that rewards you for completing Expansion Tasks. Each level gained increases your Fund Level, unlocking tiers of loot. The Basic Plan is automatically unlocked for all Proxies who meet the requirements.

Rewards Breakdown

Basic Plan (free) – Standard tier rewards including Polychrome and upgrade materials.

Growth Plan (paid) – Instantly grants Polychrome ×680 and the exclusive avatar "Focus on This!". Additional rewards include a menu decoration set, W-Engine Microcontroller Unit, Resonating Core, and Ether Batteries as you level up.

Premium Plan (paid upgrade) – After purchasing the Growth Plan, you can upgrade to Premium for an extra Polychrome ×208, plus a second set of premium milestone rewards. The Premium Plan also grants the exclusive namecard "The Truth of the World!", more W-Engine Microcontroller Units, Resonating Cores, Hamster Cage Passes, and your choice of upgrade material type at certain levels.

Important: At Fund Level 30, both Growth and Premium plans reward a Great Builder's Certificate. This is a time-limited currency that expires at the end of the current City Fund period. Use it before the next season starts.

After purchases are closed, you can still complete Expansion Tasks and claim earned rewards until the event ends. Plan accordingly.

Tips for F2P and Low-Spend Players

  • F2P: Stick with the Basic Plan. Complete daily and weekly Expansion Tasks to reach higher Fund Levels. Focus on the free Polychrome and upgrade materials — they add up over the season.
  • Growth Plan: Worth it if you value the avatar and extra Polychrome plus the convenience of extra materials. The instant 680 Polychrome alone helps for pulling.
  • Premium Plan: Consider only if you need the namecard and the additional Hamster Cage Passes. The extra Polychrome (208) is modest, but the upgrade materials could save you battery charge.

For those considering a purchase, weigh the exclusive cosmetics and material efficiency against your Polychrome budget. The event runs through July 27, 2026, so you have plenty of time to level up.
