How do I unlock prologue act 2 on Genshin Impact? I’m already on AR11.
It should naturally unlock itself when you’re done with prologue act 1. That is, when you did quests in all three temples around Mondstadt. And you need AR 10+, which you’ll probably have at that point.
According to the wiki, act 2 starts with you reporting to Jean, so why don’t you try visiting her in Knights of Favonius headquarters?
