Hero Crystal In Miscellaneous
So trying to 100% variant 4, doing the final quest, you really are restricted because most people dont have alot of 1* champions. And buying that crystal gives you a very slim chance to get a 1* champion which I seriously think should be reconsidered. I mean 50 units for a 2* star champ is pretty messed up on its own, but odds are, if you are getting that crystal, you're aiming for a 1* champ. If anything I think the odds should be flipped where its 80% chance to get a 1* champ or just simply make a crystal that has only 1* champs. Not having a good access to 1* makes completing the content of variant 4 that much more difficult, and a little too far fetched.
