What are the requirements to receive a chest? I haven't received a hextech chest in months. I have 7 complete keys now and no chests to unlock. My account says there are 4 available, but I just can't seem to get one. Is there something special I need to do to unlock one? I've also received several S-, S, and even S+ ratings in the past few months, but no chest.
You must have an S- or higher and it cannot be for a champion that you have already revived a chest on. If you go to your profile and look at your champions if they have a golden border then you've already gained a chest for them for the season.
Receive S(-/+) grades on champions that you own (not free week), while playing on ARAM or Summoner's Rift. You can only get ONE chest per champion per season.
You can also play in a pre-made team with friends, and if one of those people gets an S grade, you will get a chest on the champion you played (unless you already got one with that champion).
