Oh no I've gotten into Genshin Impact now it's on Xbox ddd
Oh maybe i should open the Genshin / HSR thread
Seriously though aside from Welkin Moon and the rare Battle Pass, don't spend anything on top ups. Don't spend anything on the weapon banner as a F2P as it still remains a scam and don't convert your primogems into blue fates (wishes for standard banners).
Other than all this, i think it remains a great game and time sink as you can easily clear 95% of the content with anyone and any team you like. Leave us an update once you do Fontaine cause it is the peak of Genshin.
