Welp, good luck. I don't know if you will get her or not, I also tried to get Childe but I couldn't get enough primo, i got near the pity tho(i also had the blessing moon), but at that time i didn't do things like Abyss, so if you try to get her doing the daily missions, Abyss, events, codes(?), etc. you may get her... If you buy the blessing moon and the battle pass that would help too
