Hearthstone has introduced a new Recruit-a-Friend feature that can help get friends who don’t play much Hearthstone–or haven’t at all–back into the game. And if you’re the one to invite them, then you could earn a free Shaman hero and some packs.

All you have to do to get some free stuff is share your recruitment link, which you can get from here after logging into Battle.net. After using your link, your friends will receive a welcoming message that says they’ll earn a free pack of cards once they’ve created an account and played through the introductory missions. Once they do this, you’ll get your reward.

The first recruit earns you Morgl the Oracle, a new Shaman hero, while the next four recruits will each get you a Classic card pack. However, it’s worth noting that for the recruit to be eligible they can’t have any classes already at level 20. You can learn more at Blizzard’s website.

Hearthstone’s latest expansion, Whispers of the Old Gods, released back in April. It introduced the C’Thun card, which can be buffed by other Old Gods cards at any time–even if it’s not in your hand. You can see all 134 Old Gods cards right here.
