Genshin Impact Version Luna II: What You Need to Know
HoYoverse has confirmed that Genshin Impact's next major update, officially titled Version “Luna II”: Song of the Welkin Moon – Reprise, will launch on October 22, 2025. This update builds on the preceding “Luna I” release and brings significant new content—most notably a user-generated content (UGC) system, a new playable 5-star character, refreshed event cycles, and new story quests.

Key Features & Content Highlights
1. Miliastra Wonderland (UGC System)
Possibly the biggest headline of this version: the introduction of Miliastra Wonderland, an in-game UGC hub. Players will be able to create, share, and explore custom stages created by the community—ranging from mini-games to adventure-style levels. This system promises to deepen Genshin's sandbox elements and give players new ways to engage beyond the standard open-world questing.
2. New Character: Nefer
Version Luna II introduces Nefer, a 5-star Dendro Catalyst user whose kit revolves around the Lunar-Bloom reaction system. Her arrival is paired with a banner that runs from October 22 to November 11 (Phase 1) and is followed by a second phase featuring rerun characters like Arlecchino and Zhongli from November 11 to December 2.

3. New Archon Quest & Story Progression
The Archon Quest reaches further into the Nod-Krai region's lore—players will face the looming threat of the “Rächer of Solnari” and see alliances formed with unlikely characters.
4. Maintenance Schedule & Update Size
Due to the scale of changes, maintenance for the update is scheduled for approximately seven hours—longer than the usual five. Region-by-region timing is listed by HoYoverse. Pre-load sizes: PC ~11 GB; mobile ~4 GB.
Why This Update is Important
Version Luna II isn't just another patch—it feels like a pivot. With UGC tools, Genshin moves toward being both an open-world action RPG and a creative platform. For players, that means beyond grinding and questing, you'll soon build or explore custom content. The character lineup continues to expand, and the lore in Nod-Krai deepens. If you've been playing casually, this is a strong moment to return; if you're a veteran, there's new meta and content to master.
What Players Should Do Before the Update
Save Primogems and Intertwined Fates for the Phase 1 banner (Nefer + plus rerun) if you're planning pulls.
Complete current Archon Quest content so you're ready to dive into Act 3 when the update hits.
Free up space on your device (PC/mobile) to pre-load the update—especially helpful for smooth start.
Check your schedule: With longer maintenance, log-in events may begin later than usual; plan accordingly.
Prepare for UGC content: If you're interested in creating stages or exploring player-made ones, consider which characters/weapons you want ready for creative modes.
Final Thoughts
Version Luna II marks a major milestone for Genshin Impact. It's not only delivering new characters and story but also unlocking a mode that allows players to be creators. The challenge for HoYoverse will be to balance that creative potential with the core gameplay players love. For you as a Traveler: this update offers new narrative, new mechanics, and new freedom.
