A new referral season is here: starting August 1, refer your friends and claim your very own mount skin! The Ironjaw Hyena skin turns your Direwolf base mount into a wild, warlike Hyena girded in iron - and like all mount skins, once you've unlocked it, it can be used by all characters on your account forever.
On top of that, you can earn huge amounts of Fame for your third and fifth referrals: three referrals scores you a T7 Pile of Tomes worth 100,000 Fame, and five referrals gets you a T8 Pile of Tomes granting a colossal 200,000 Fame. And as always, your first-ever referral grants an additional T8 Pile of Tomes along with the mount skin.
The current referral season lasts until maintenance on October 1, so you've got until then to refer your friends and claim your rewards.
