How do you get the DWG Kennen Signature Icon?
It was a mission or event reward. Riot's description in the client reads: “Honoring Nuguri's winning Kennen in the 2020 World Championship”
Is the DWG Kennen Signature Icon still available?
No. Riot tied the DWG Kennen Signature Icon to 2021 (mission reward), and it does not normally bring back past event rewards or bundles.
