Arknights Endfield Si banner ends on November 5, 2026 at 11:59 server time. Rejuvenation features six-star operator Si, and you unlock the event by finishing Chapter I Process I: Break the Siege. You can spend Spirit’s Restoration HH Permits, Chartered HH Permits or Oroberyls to recruit.
Before Rejuvenation closes, there are three useful things to do: collect sign-in permits, check the AIC Quota Exchange offers and try Si in Combat Drills. The headhunting milestones offer bonuses, but they don’t change which six-star operator you receive.
Arknights Endfield Si banner end date and unlock
When does Rejuvenation close?
Rejuvenation ends on November 5 at 11:59 server time. Asia uses UTC+8 and Americas/Europe uses UTC-5, so the deadline depends on the server your account uses, not the local clock on your device.
You need to finish Chapter I Process I: Break the Siege to participate. Once the mission is complete, check Headhunting for Rejuvenation. Si is the featured rate-up six-star; the other possible six-star operators are Typhoeus, Liino, Ember, Lifeng, Ardelia, Last Rite and Pogranichnik.
How to get the correct Si permits
The Arknights Endfield Si banner accepts Spirit’s Restoration HH Permit, regular Chartered HH Permit and Oroberyls. The special Spirit’s Restoration permits are intended for this event, so do not assume they can be carried into the next banner.
Spirit’s Restoration is a seven-day sign-in event with five of those permits among its rewards. You can also exchange AIC Quota for up to five discounted Spirit’s Restoration HH Permits. Check the AIC Quota Exchange for the current item price; the announcement confirms the purchase cap, not a single universal amount.
What do 30, 60 and 240 pulls award?
After 30 headhunting attempts, the banner grants ten Urgent Recruitment attempts. This free ten-pull is valid only during Rejuvenation and guarantees at least a five-star operator. GRYPHLINE explains that Urgent Recruitment attempts do not count toward normal headhunting guarantees or the banner’s attempt-reward milestones.
At 60 attempts, you receive a Headhunting Dossier. It converts into ten special HH Permits for the next Chartered banner when that banner begins; those converted permits also expire when the following banner ends. A token for the featured six-star operator is awarded every 240 attempts. These are extra rewards, not a fixed-pull guarantee of Si.
How to try Si without pulling her
The Arknights Endfield Si banner includes Combat Drills. Open the operator trial, play the specified stage with its preset team, then claim your reward from Event Center. This is a chance to test Si without using headhunting currency.
The announced reward includes 100 Oroberyl, an Arsenal Defense Crate and Mark of Perseverance. The crate contains a fully artificed level-60 gear set intended for the trial operator. Follow the challenge conditions shown in-game rather than assuming every trial stage has identical objectives.
What happens when the Arknights Endfield Si banner ends?
The next Chartered Headhunting event features Argent Flow and begins November 5 at 12:00 server time. Its special permits are The Stars Are With Me HH Permits, not Spirit’s Restoration HH Permits. The two banners have different rate-up operators and sign-in events.
Si may also appear in the next banner’s published operator pool, but that is not the same as remaining its featured rate-up. Check our Argent Flow guide before deciding where to spend ordinary Chartered HH Permits or Oroberyls.
Arknights Endfield Si banner: what to do before it ends
If you still have access to Rejuvenation, finish the unlock mission, claim available sign-in rewards, check AIC Quota Exchange and complete Combat Drills. Only then decide whether to spend additional currency on pulls.
Check the rewards you can still claim before the November 5 changeover: the trial, any remaining sign-in permits and the discounted exchange. Then decide whether you want to spend more pulls on Si.
