How do you get the Witch's Brew Blitzcrank Border Icon?
It came in a bundle. Riot's description in the client reads: “This icon was released as a bundle exclusive during the 2019 Tales from the Rift event.”
Is the Witch's Brew Blitzcrank Border Icon still available?
Probably not. Riot tied the Witch's Brew Blitzcrank Border Icon to 2019 (bundle), and it does not normally bring back past event rewards or bundles.
