I got them all except Keqing, lol- I’m newer to Genshin, not even past Liyue Archon quest and knowing most things about it from the internet I got them mostly through what they said, not how they sounded lol
Got all of them, Genshin gets a lot of shit but man they do make very distinct characters with silhouettes you recognize. It’s even more impressive when there are only 5 model types in the game.
