The Mid Season Invitational for 2022 will be held in South Korea from May 10 through May 29. Pros will begin arriving beforehand to bootcamp and play on the KR server. When players come to a different region for a tournament, Riot gives them special accounts to use which have all skins, champions, and other goodies unlocked. This is one way you can tell an account was created by Riot for a player because it will have all 20 rune pages unlocked, be a fresh account but already level 30. These accounts also start with a Platinum 1 internal MMR which means they automatically start off against players around Platinum 1 or Diamond 4 in their first ranked games.
If you know an account belongs to a player that isn't on the list (or you need to correct an account that's assigned to the wrong player) use the form below to tell us!
