There is excellent news for every fan of League of Legends who would like to have a skin for their favorite champion without actually giving money to this phenomenal free-to-play game. They will be able to do that via the Microsoft Rewards system.
Riot is not a stranger to giving out free RP. Even when the game just started, players who lacked some RP to buy a skin could send in a drawing of their favorite champion in paint, and they would be given up to 100 RP for a missing skin.
Last year, as everyone who is into LoL esports is already aware of, the Twitch Prime Capsules were introduced, and by being subscribed to Twitch Prime (even with the free trial), you would get 650 RP along with a lot of other goodies. But how does the system work with Microsoft Rewards, and is it worth it?
