How do you get the Shurima 2014 - Perfect Ascension?
It was a mission or event reward. Riot's description in the client reads: “Earned by winning a game of Ascension where the enemy team does not obtain the Ascension buff during the 2014 Ascension event.”
Is the Shurima 2014 - Perfect Ascension still available?
No. Riot tied the Shurima 2014 - Perfect Ascension to 2014 (mission reward), and it does not normally bring back past event rewards or bundles.
