How do you get the Legendary Variant Dark Cosmic Lux Border Icon?
It came in a bundle. Riot's description in the client reads: “This icon was released as a bundle exclusive during the 2020 Galaxies event.”
Is the Legendary Variant Dark Cosmic Lux Border Icon still available?
Probably not. Riot tied the Legendary Variant Dark Cosmic Lux Border Icon to 2020 (bundle), and it does not normally bring back past event rewards or bundles.
