How do you get the EDG Graves Signature Icon?
It was a mission or event reward. Riot's description in the client reads: “An icon honoring Flandre's winning Graves in 2021 World Championship.”
Is the EDG Graves Signature Icon still available?
No. Riot tied the EDG Graves Signature Icon to 2022 (mission reward), and it does not normally bring back past event rewards or bundles.
