This week, we're asking you to play as a champion that has stealth. Simply play three games as any champion that has invisibility on any map (Summoner’s Rift, The Crystal Scar, The Shadow Isle, Howling Abyss, Team Builder).
This week's challenge is easy: play 3 games with a champion that is invisible. We've included all champions that stealth, even those who only do it briefly.
Update: we have extended this contest and DOUBLED the prizes due to the Riot API being down intermittently for about four days due to the champion mastery. We had so many emails about people unable to enter, we wanted to ensure all of those who played the champions could.
