The new Labyrinth Warriors event started and it feels really nice so far. Seeing Childe and Xinyan interacting isn't something I thought I'd ever see, but it's a lot of fun. Also figures he'd be the person you'd find skipping about in an excessively dangerous area.
My only gripe with the event is that it's not co-op. The event being roguelike dungeons feels perfect for multiplayer, but it's still a lot of fun nonetheless.
