How the Fund Operates

Proxies earn rewards by completing various Expansion Tasks, which raise their overall Fund Level. The Basic Plan is accessible to all players automatically upon meeting the entry requirements, granting standard progression items at no cost.

Breaking Down the Tiers

Basic Plan (Free): Provides consistent, baseline rewards such as Polychrome and essential upgrade materials.

Growth Plan (Paid): Immediately awards 680 Polychrome and the “Focus on This!” avatar. Advancing your level unlocks additional resources, including menu decorations, W-Engine Microcontroller Units, Resonating Cores, and Ether Batteries.

Premium Plan (Paid Upgrade): This is an add-on to the Growth Plan. It provides an extra 208 Polychrome, the “The Truth of the World!” namecard, and deeper milestone rewards, such as extra W-Engine parts, Resonating Cores, Hamster Cage Passes, and flexible upgrade materials.

Note: Reaching level 30 on either paid plan awards the Great Builder’s Certificate. Be sure to spend this specialized currency before the current season concludes, as it will expire.

Essential Dates

While the purchase period ends on July 27, 2026, at 02:59, players can continue to earn progress and collect rewards through the end of the event at 03:59 (server time).

Strategic Advice

• F2P Players: Focus on maximizing your daily and weekly Expansion Tasks to climb the tiers of the Basic Plan for free resources.
• Growth Plan: Recommended for those who want the exclusive cosmetic avatar and a significant boost to their Polychrome stash for upcoming banner pulls.
• Premium Plan: Best suited for players aiming for the unique namecard and the resource efficiency provided by extra Hamster Cage Passes and upgrade items.
