Riot Girl Tristana, Unchained Alistar and Dreadknight Garen will cease to be available as free skins August 1 as Riot Games discontinues social promotion, according to a Riot Games support article.

In the ​support article, Riot explains that each of these skins have been available for years to players who followed Riot on Facebook, YouTube and Twitter respectively. As the game has grown, these promotions have become less useful to Riot. Additionally, the game's art quality has improved significantly, leading to the discontinuation of these older skins.

For a limited time, all three skins can be obtained at once by submitting a support request on Riot's website rather than by following the developer on Facebook, YouTube and Twitter. The request can be submitted up until the August 1 deadline.

Riot Girl Tristana and Unchained Alistar will no longer be available at all, while Dreadknight Garen will remain purchasable in the the store for 975 RP.
