it's officially been a year of playing for me. honestly, since i ended up buying a lot of 6* girls and a few 5* ones, I probably spent at least 6-7 50 gem pulls on stamina refills...
i honestly felt like the event 5* girls was enough to hold me until I got some 6* ones, but I did do a few 50 gem pulls as well and got lucky (like a dupe Lycoris falling into my lap from the last one)
