• Duration: 2026-09-30 10:00 – 2026-10-19 03:59 (server time)
• Eligibility: Inter-Knot Lv. 20 + Main Story Chapter 1 – Intermission

How Orbie-volution Works

During the event, Proxies receive a game console called Orbie-volution to start an exclusive Orbie upgrade plan. The core loop revolves around collecting Grub, the event currency used to upgrade your Orbie pets.

You can earn Grub in two ways each day:

• Daily login: 2 Grub
• Spend 30 Battery Charge: 1 Grub

That's a maximum of 3 Grub per day. Over the full event window (19 days), you can earn up to 57 Grub if you log in and spend Battery Charge daily. Missing days means fewer upgrades, so consistency matters.

Upgrade Progress and Carryover

A crucial detail: only fully upgraded Form pets carry over to subsequent events in this series. If you partially upgrade a pet during the event, that progress is lost when the event ends. This means you should focus on completing one pet at a time rather than spreading Grub across multiple pets.

Rewards and Missions

Beyond the pet upgrades, Orbie-volution includes limited-time reward missions. Completing these missions grants:

• Polychromes
• Title: "Chosen Zookeeper"
• Various upgrade materials

The exact number of Polychromes and materials is not stated in official materials. Based on similar events, expect a modest but useful sum, likely in the range of a few hundred Polychromes. We'll update if HoYoverse shares specifics.

Should You Prioritize This Event?

If you're a regular player, yes. The daily Grub routine is low-effort: log in, spend 30 Battery Charge (which you likely do anyway for dailies), and you're done. The main risk is forgetting to log in or letting Battery Charge cap. Set a reminder if needed.

For F2P players, the Polychromes are the main draw. The title is cosmetic, and upgrade materials are helpful but not game-changing. Still, the event is generous with minimal time investment.

Tips for Efficient Farming

• Log in daily to claim the 2 Grub from login. This is the easiest part.
• Spend 30 Battery Charge each day. You can do this by running routine missions, farming materials, or any activity that consumes Battery Charge. Don't let it sit at cap.
• Focus on one pet at a time to ensure you fully upgrade it before the event ends. Check the upgrade costs and plan your Grub spending.
• Complete reward missions early to avoid last-minute rushes. The missions are limited-time, so knock them out as they appear.

Event Timeline and Planning

The event runs for 19 days, from 2026-09-30 to 2026-10-19. Here's a quick breakdown of key dates:

If you start on day one and play daily, you'll have enough Grub to fully upgrade at least one pet, possibly more depending on costs. If you start late, prioritize the pet you want to carry over.

Conclusion

Orbie-volution is a straightforward daily-login event with a clear reward structure. The main things to remember: hit Inter-Knot Lv. 20, complete Chapter 1 – Intermission, and log in daily to collect Grub. Spend 30 Battery Charge each day, and focus on fully upgrading one pet to keep it for future events.
