"A Spring Note, Warmly Crafted" is a sharing event running inside Arknights: Endfield as part of the broader Grand Blessings for the Spring celebration. It asks you to craft holiday cards tailored to individual operators' preferences, clear stage challenges, and collect rewards that include Oroberyls, Emergency Sanity Concentrate, and other seasonal items. The event launched on February 15, 2026 and runs through March 4, 2026.
Quick answer: Craft a card for each operator by matching the decorations and imagery to their personal description, complete the stage challenge, and use the share function after finishing at least three stages to unlock Free Crafting and claim all available rewards.

Event window and server time zones
The event is active from February 15, 2026, at 12:00 through March 4, 202,6 at 04:00 (server time). Asia servers operate on UTC+8, while Americas and Europe servers use UTC-5. All deadlines and unlock dates follow the server time zone relevant to your account.
Participation requirements
You must have completed the main mission Chapter I Process I: Break the Siege before the event becomes accessible. If you haven't reached that point in the story yet, push through the early campaign first — the event will appear once that mission is cleared.

How the card-crafting stages work
The event contains seven stages in total. Three are available from the start, and the remaining four unlock on specific dates throughout the event period. Each stage is tied to a particular operator, and the goal is to assemble a holiday card that matches what that operator likes.
Every stage gives you a text description of what the operator wants to see on their card. You then pick from a set of visual elements — paper cuttings, food items, decorations, and background imagery — to build a card that satisfies the description. Getting the right combination earns a three-star rating on that stage.
Some of the English-language hints can be tricky to interpret. A few common stumbling points players have encountered early on:
- Perlica's stage mentions a "paper cutting of you holding a lantern and playing with children," but none of the selectable art pieces literally depict the Endministrator. Look for imagery that evokes the spirit of the description rather than a literal portrait.
- Ardelia's stage describes something with a "hard but fragile outside, melty in the center." The correct match is a lava cake — the volcano connection is the key thematic link, not a conventional filled pastry.
If you get stuck, you can retry each stage as many times as needed with no penalty. Experiment with different combinations until the description is fully satisfied.

Rewards and how to claim them
Completing a stage mission sends the associated rewards directly to your in-game Mail. Reward mails expire after 30 days, so don't let them sit uncollected for too long.
Once you finish any three stages, the Free Crafting stage unlocks. This mode lets you build custom cards with no operator-specific constraints. Importantly, cards made in Free Crafting are not auto-saved — you need to save them manually if you want to keep them.
After creating a card in Free Crafting, use the share function to earn additional rewards. Sharing is a separate step from simply completing the card, and skipping it means leaving rewards on the table.

"Grand Blessings for the Spring" companion events
Two other events run alongside "A Spring Note, Warmly Crafted" under the same seasonal umbrella. They operate independently, so you can participate in all of them simultaneously.
| Event | Duration | Key rewards |
|---|---|---|
| Fortune Connect-and-Win | Feb. 15 – Feb. 23, 2026 | Oroberyls (up to 880 guaranteed on select days), Emergency Sanity Concentrate, Sanity Usage Permits |
| Steps to Sweet Success | Feb. 16, 17, & 21, 2026 | Springfest Pastry (recovers 40 Sanity, permanent item), Mark of Perseverance, Operator Gifts ×3 per mail |
The Fortune Connect-and-Win event delivers one mail per day for nine days. On February 15, 16, 17, and 21, the scratch card inside upgrades to a "Connect-and-Win: Luck" variant that guarantees 880 Oroberyls. Each mail expires 14 days after you receive it.
Steps to Sweet Success sends three mails from Gilberta, Laevatain, and Yvonne on February 16, 17, and 21 at 20:00 server time. The Springfest Pastry included in each mail is a permanent consumable — it doesn't expire and restores 40 Sanity per use. The Operator Gifts can be given to operators in Dijiang once you've unlocked the Offering Gifts feature by reaching Chapter I Process II: Remediation Progress.

Deadlines worth tracking
With multiple overlapping mail windows and claim deadlines, it's easy to miss something. The most important dates to keep in mind:
| Deadline | What expires |
|---|---|
| Feb. 22, 2026 at 23:59 | Last day to create a character and qualify for mail events |
| Mar. 1, 2026 at 12:00 | First Fortune Connect-and-Win mail claim deadline |
| Mar. 4, 2026 at 04:00 | "A Spring Note, Warmly Crafted" event ends |
| Mar. 7, 2026 at 20:00 | Final Steps to Sweet Success mail claim deadline |
| Mar. 9, 2026 at 00:00 | Final Fortune Connect-and-Win mail claim deadline |
The card-crafting event is lightweight but easy to overthink, especially when the operator descriptions don't map neatly onto the visual options. Focus on thematic connections rather than literal matches, share your Free Crafting cards for the bonus rewards, and check your in-game Mail regularly so nothing expires before you collect it.
