Arknights: Endfield is running a trio of Spring Festival events under the Grand Blessings for the Spring banner. All three are live now and staggered across different start dates and claim windows, so keeping track of what lands in your mailbox — and when it expires — matters more than usual.
Quick answer: Log in daily to claim Fortune Connect-and-Win scratch cards (through Feb. 23), craft holiday cards in A Spring Note, Warmly Crafted (through Mar. 4), and collect three operator blessing mails on Feb. 16, Feb. 17, and Feb. 21 at 20:00 server time. You must create a character before Feb. 22 at 23:59 server time to qualify for the mail events.
Fortune Connect-and-Win mail reward event
This daily login mail event runs from Feb. 15 through Feb. 23, 2026 (server time), delivering a total of nine mails over the period. Each mail contains one Connect-and-Win scratch card that awards Oroberyls, one Emergency Sanity Concentrate, and five Sanity Usage Permits.
Four of those days carry upgraded rewards. On Feb. 15, Feb. 16, Feb. 17, and Feb. 21, the standard Connect-and-Win: Auspice card is replaced by a Connect-and-Win: Luck card, which guarantees 880 Oroberyls per scratch. That's a potential 3,520 Oroberyls across those four days alone, so missing them stings.
Claim deadlines are staggered. The first mail must be claimed by Mar. 1 at 12:00 server time, the second by Mar. 2 at 0:00, and each subsequent mail's deadline shifts one day later. The final mail expires on Mar. 9 at 0:00. Every mail also carries a hard 14-day expiration timer from the moment it arrives, so even if the rolling deadline hasn't passed, an unclaimed mail will vanish two weeks after delivery.
To participate, you need to have created a character before Feb. 22 at 23:59 server time and unlocked the Mail feature in-game.
A Spring Note, Warmly Crafted sharing event
Running from Feb. 15 at 12:00 through Mar. 4 at 04:00 (server time), this is the most interactive of the three events. You craft holiday greeting cards tailored to what specific operators like, then complete stage challenges tied to each card. Operators respond with their own Spring Festival greetings in return.
The event has seven stages total. The first three are available immediately, while the remaining four unlock on specific dates throughout the event window. Completing any three stages opens a Free Crafting mode, where you can design and share custom cards for additional rewards. Cards made in Free Crafting are not auto-saved, so you'll need to save them manually before leaving.
Rewards for completed missions are sent directly to your in-game Mail and expire 30 days after delivery. The prerequisite here is different from the other two events — you need to have finished the main mission Chapter I Process I: Break the Siege rather than just having created a character.
Tip: Some of the card-crafting hints can be tricky in English. Ardelia's stage, for instance, describes something "hard but fragile outside, melty in the center," which refers to a lava cake — a nod to her volcanic theming. If a clue stumps you, think about the operator's lore and elemental associations rather than taking the description too literally.
Steps to Sweet Success operator blessing mails
This is the smallest of the three events but delivers some of the most useful items. Three mails arrive at 20:00 server time on Feb. 16, Feb. 17, and Feb. 21, sent by the operators Gilberta, Laevatain, and Yvonne respectively.
Each mail contains:
- Springfest Pastry ×1 — a Spring Festival exclusive consumable that permanently sits in your inventory and restores 40 Sanity per use
- Mark of Perseverance ×1
- Operator Gift ×3
The Springfest Pastry is the standout here. Unlike most event consumables, it doesn't expire and remains usable indefinitely, making it a reliable Sanity recovery tool well beyond the festival period.
Operator Gifts require a bit of progression to actually use. You need to advance the main story to Chapter I Process II: Remediation Progress, which unlocks the Offering Gifts feature. Once that's available, head to Dijiang to hand the gifts to your operators.
Claim deadlines for the three mails are Mar. 2 at 20:00, Mar. 3 at 20:00, and Mar. 7 at 20:00 server time, respectively. Each mail also expires 14 days after receipt, whichever comes first.
Server time zones and eligibility cutoff
| Server region | Time zone |
|---|---|
| Asia | UTC+8 |
| Americas / Europe | UTC-5 |
All event times reference server time, so convert accordingly based on your region. The universal eligibility requirement for the two mail-based events — Fortune Connect-and-Win and Steps to Sweet Success — is character creation before Feb. 22 at 23:59 server time and having the Mail feature unlocked. A Spring Note, Warmly Crafted instead gates entry behind completing the Chapter I Process I main mission.
Between the three events, you're looking at thousands of Oroberyls from upgraded scratch cards, three permanent Springfest Pastries, Emergency Sanity Concentrates, Operator Gifts, and whatever the card-crafting missions yield. The biggest risk is simply letting mails expire — especially the Fortune Connect-and-Win cards with their rolling daily deadlines. Set a reminder if you need to, because the 14-day expiration timer is unforgiving once a mail lands.
