Finally done the Shinra Combat Simulator Rank 7 Challenge, found shiva tricky until i figured out her pattern haha, kinda confused me at first but its easy
the trick is arcane ward, charge up ATB on all characters, once all charged unleash Firaga all at once
once she gets hit by fire she changes to a defensive mode and if you attack her with fire again then she will counter with blizzard so you want to beat her quick
you can check if shes in defensive mode by pressing the touchpad on the PS4 controller, check her weakness, if its Fire then you can attack her with fire obviously, if not, melle only until she exits that mode
