How do you get the On Duty Icon?
It was an esports viewing reward. Riot's description in the client reads: “Unlocked by watching games during the 2018 Worlds event.”
Is the On Duty Icon still available?
No. The On Duty Icon dropped to viewers who watched LoL Esports broadcasts or finished LoL Esports missions in 2018. Riot does not hand out past esports drops again, so you cannot earn this icon anymore.
