League of Legends Free Skins
3 skins you can get are for: Garen, Tristan and Alistar, that only requires you to follow offical Riot social media pages. There are also 2 other skins that can get free, but they require you to get affiliates and takes much more work to get. I started playing at season 2 and at that time Riot was promoting these 3 skins on their offical site. Now, they have removed those advertisments and only those who know about it can tell you.
Basically what you have to do, is that you have like/follow Riot social media pages (Facebook, Twitter) via 3rd party site, woobox.com. It's 100% legal and doesnt require account creation or anything else. You find below all the links for each skins.
Long story short: Get free skins for following Riot social media pages.
