How do you get the Worlds 2024 Viego Border Icon?
It came in a bundle. Riot's description in the client reads: “An icon that entitles the border for this champion.”
Is the Worlds 2024 Viego Border Icon still available?
Probably not. Riot tied the Worlds 2024 Viego Border Icon to 2024 (bundle), and it does not normally bring back past event rewards or bundles.
