I have read a couple times that players had great luck with an elemental summon when done right when the colors change over. I had been planning a 10 pull on Ice for a couple days and I just happened to be almost in bed when it changed over the last time, so I went for it. This was 30 seconds or so after the Ice became active. I was really hoping for Grimm to back up Kiril. Here’s what I got:
Magni, Isarina, Grimm, Sonya, Ulmer X3, Graymane X2, and Karil
Score! I don’t know how you would ever test this short of spending quite a lot of gems, but here’s another success using this approach.
