My account is level 12 and has enough to buy a chest of the legendary king, but the update arrived and I don’t know if I will have a champion.
As a level 12 account you can get champions as long as you have reached Arena 16, as that’s where the first 2 champions are unlocked.
Since arena 16 is locked to level 33, I am guessing it’s not possible?
It would be helpful if you would share a link to your profile so that we can see exactly your levels.
