Do I still have to save cards after level 175? I have plenty of level 8 cards but I’ve been saving them in case I had to use them for some grind wall or something. And if I do have to save them, what level do I use them?
You could use them to hit lv187 (exp curve reset), grind quickly to 190, do the dungeons and use the remaining for the last levels depending on how many are available.
