Nefer already released in Genshin Impact in the first phase of the Luna II (version 6.1) update, so she is not a future unreleased character anymore.

Quick answer

  • Nefer’s debut banner ran in Phase 1 of Luna II / 6.1 , starting around October 21–22, 2025 depending on your time zone.
  • That first banner lasted until roughly early–mid November 2025 as part of the standard 21‑day Phase 1 schedule.

What was officially announced

  • Nefer was announced as a 5‑star Dendro Catalyst character from the Nod‑Krai region, featured on the Phase 1 character banner for Luna II.
  • Official schedules and news posts list her banner as tied to the Luna II / 6.1 update , with the patch going live on October 22, 2025 (UTC+8) and Nefer’s banner starting alongside it.

Time zone details

Sources that broke down the release give slightly different local times, but all align on that late‑October window:

  • Around October 22, 2025 at 11:00–13:00 (UTC+8) for Asia servers, when the update finished maintenance.
  • For Americas, this translated to the evening of October 21, 2025 due to time zone differences, which is why some banners are listed as October 21–November 11 in local time.

Banner window

  • Phase 1 of version 6.1 (with Nefer’s debut and a Furina rerun) is documented as lasting about 21 days , from October 22 to around November 11–12, 2025.
  • After that, Phase 2 banners took over with other 5‑stars, so Nefer’s first limited run ended at that point.
