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