How do you get the Snowflake Icon?
It was an event pass reward. Riot's description in the client reads: “Acquired by purchasing the 2018 Snowdown Pass during the 2018 Snowdown event.”
Is the Snowflake Icon still available?
No. Riot tied the Snowflake Icon to 2018 (event pass), and it does not normally bring back past event rewards or bundles.
