The new Version 4.1 update has arrived! In this guide, we will walk you through the Archon Quest Chapter IV: Acts 3 & 4. In this update, we have new characters, exciting quests, a plethora of additional features, and fresh areas to explore.

After the Version 4.0 Archon Quest, Neuvillette has asked the Traveler to visit the imprisoned Childe in the Fortress of Meropide. To get inside the Fortress, which runs on its own, the Traveler must disguise themselves as a criminal who has been caught and convicted.

While searching for Childe, the Traveler will meet Wriothesley, the administrator of the Fortress of Meropide, and look into some incidents that have taken place in the prison. Check out what the latest Genshin Impact update brings.
