How do you get the Season 2021 Split 1 Icon?
It was a ranked reward. Riot's description in the client reads: “This icon was earned by winning ranked games in Season 2021 - Split 1.”
Is the Season 2021 Split 1 Icon still available?
No. The Season 2021 Split 1 Icon was a ranked reward. To earn it, you had to peak the required rank during Season 11 (2021). Riot does not hand out past ranked rewards again, so you cannot earn this icon anymore.
