Hey there all! I know this seems dodgy but it's honestly completely legit. They are 3 skins and champions that Riot give you for free, just for liking/ following/ subscribing to their social media sights.
I've got all three of the skins and champs and it is honestly fine, Riot wouldn't post it otherwise.
Sorry for all the links xD
