This time, HoYoverse surprised the Genshin Impact community with Version Luna II, set to release on October 22, 2025. One of the biggest surprises is Miliastra Wonderland, a new User Generated Content (UGC) mode that lets players build and explore worlds created by other Travelers.
Build Your World in Teyvat
Miliastra Wonderland marks a novelty for Genshin Impact. It’s similar to the Teapot system, but here, Travelers can interact far more with others.

This means every traveler can now become a World Creator, designing puzzles, minigames, and new adventures for the community!
Customize Your Avatar
In this mode, Travelers can create a special avatar called a Manekin, which can be fully customized, from hairstyle and clothing to accessories. Miliastra Wonderland also includes a Social Hub, where Travelers can gather, chat, and visit each other’s worlds. This feature pushes Genshin Impact toward a more creative and community-driven experience, closer to games like Roblox.

A Creative Playground
At the heart of this mode is the Creation Editor, a set of powerful yet easy-to-use tools. Players are free to design puzzles, spawn monsters, add visuals, or invite others to play in the worlds they build.

Of course, this poses challenges for the Genshin Impact community, maintaining content quality, performance stability, and the core feel of Teyvat in player-created worlds.
Not Just a Regular Update
In addition to Miliastra Wonderland, Version Luna II also introduces a new five-star Dendro character (Nefer), limited events, and rewards tied to Miliastra Wonderland.

This update is a major evolution for Genshin Impact players, transforming the open-world action RPG game into a platform that brings active players closer together.
With Miliastra Wonderland, Genshin Impact doesn’t just expand its world, it changes how players interact within it. For the first time, Travelers can not only explore Teyvat’s beauty, they can built it themselves!
