Can you get victorious Elise anymore and if so how

Victorious skins are basically trophies for people who reached gold division in each season.

Season 1 had Jarvan, Season 2 had Janna, Season 3 Elise, and season 4 Morgana.

There is no other way to get these skins. Once they are given out, they are unavailable forever afterwards.

No, you cannot. It was a Season 3 reward and that has long past

Lol I actually got it through a mystery skin on my smurf. Bought elise (only champ on smurf) then mystery skinned myaelf until I got it. Took me two tries

I main Elise and i think it would be cool if your reached mastery 7 with Elise then you can buy the victorious skin with RP
