Hyperion basic arena
I'm going to grind the 4* basic for the first time for hyperion, so i have some questions.
1) what's the cost of units to refresh a 4* champion? I haven't used any of the stamina refills given in the beginner calendar yet so the unit cost isn't stated.
2) I'm pretty sure I'll need to refresh to score high enough to get hyperion, but how should i refresh to score as much as possible with my top 3 champions?
E.g. use boosts on top champs, refresh until boosts expire, wait 2 hours, repeat. Or is there another way?
Thanks!
