Let’s Play Friendly Feud

"During this event two normal Hearthstone players can come together to battle it out for glory, honor, the joy of playing AND quest rewards. That’s right, for just one week you can complete quests and receive the rewards when you throw down in Friendly Challenges with your pals!

Friend list looking a little sparse? No worries! You can Recruit A Friend to join you for some Hearthstone fun! The Friendly Feud is the perfect time to introduce a new player to Hearthstone, since you can help them complete quests, earn some gold, and have a great time learning the ropes."
