As the current referral season draws to a close, it is your last chance to get your hands on the White Direwolf!
On December 15, at 11:00 UTC, this referral season ends and the current rewards will become unavailable.
The Easiest way is by sending Trial Keys to your friends. Every Key that gets redeemed on an account without a key on it will count towards your referral season progress.
So does any Starter Pack that you buy and that gets redeemed on an account without a key.
And last, but not least: if a friend registers through your referral link, then buys and redeems a Starter Pack that they bought themselves on their account, you’ll also progress.
Also remember that each redeemed Starter Pack or Upgrade by your referrals will also give you additional Gold rewards!
