For anyone who's actually playing the game and not in this crazy reroll cycle... what is the Star Quartz used for? Can ANY 4* go to a 5*? I try to awaken and they are blacked out. No they're not maxed yet but neither are some of my 3*'s but they at least give me the options. I'm on the second continent and just finished the desert. I'm loving this game so far and I never rerolled. I don't have any 5* because my luck is crap but I do have a team of 4* and they're doing just fine. Only got killed once because I wasn't paying attention on auto battle (; well then there's that time with the White Dragon hahahaha my team is around level 30 right now.
