This is something awesome that I found on the League of Legends website.
"It has now come to that glorious time when League of Legends players the world over shall band together and tell all of their friends to come join them in combat on the Field of Justice! And why, you ask? Because we're going to give you free stuff for doing so!
As we all know, League of Legends is more fun when you play it with your friends. And so, to encourage you to help your friends broaden their horizons, we're going to give you rewards for getting them to sign up. Every time someone that you have referred reaches summoner level 10, you’ll be eligible for a reward. This reward can be anything from an IP boost, to a unique champion skin, to a free trip out to the Riot Office in sunny California to design your own champion.
Here’s how it works: every fifth friend that reaches level 10 will net you an IP boost that you can redeem whenever you want. In addition, every time you reach one of the following reward tiers, you will receive a unique reward.
* 10 - Tier 3 Champion
* 25 - Forum Title - “Recruiter”
* 50 - Grey Warwick Champion Skin
* 100 - The League of Legends Digital Collector’s Pack
* 150 - Forum Title - “Senior Recruiter”
* 200 - 10,000 Riot Points
* 250 - Forum Title - “Master Recruiter”
* 350 - Ultra-rare champion skin - Champion will be selected by the first player to reach this tier*
* 500 - Get your name added to the “Wall of Fame” in the Riot Office
* 1,000 - A content element will be named after your summoner
* 5,000 - All current and future content permanently unlocked
* 10,000 - All expenses paid trip to visit Riot Games and develop a champion with the Riot Design Team
So, what are you waiting for? Get out there and spread the word! You know that you all want to design your own champion with the League of Legends team. 10,000 friend referrals is child’s play for a well connected socialite such as yourself! Either that, or at least get 5 buddies to come help you earn a free IP boost!"
So yeah... Help me out, and signup! It's free.
