Tonight's co-op guest was a Childe/Bennett to go with my Ganyu/Qiqi (Qiqi sometimes replaced with Klee). We were both just killing time but they helped me get a few chests that I hadn't found yet and I got the achievement for co-oping a pyro regisvine even though I don't think either of us took the reward for that. They seemed like a pretty good player and the whole thing was just wholesome chill. #GenshinImpact
