How do you get the Prestige Mythmaker Cassiopeia 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 Prestige Mythmaker Cassiopeia Border Icon still available?
Probably not. Riot tied the Prestige Mythmaker Cassiopeia Border Icon to 2025 (bundle), and it does not normally bring back past event rewards or bundles.
