Basics
The Apprentice Pass contains special Challenges for new players where you can earn rewards to help boost your progress. You can find the Passes window in the Bastion.

Apprentice Pass Rewards
Completing Daily and Apprentice Challenges will grant you Apprentice Pass Points, and more Points increases your Apprentice Pass Level. Each new Level earned in the Apprentice Pass will grant you a reward. There are two types of Apprentice Pass - Starter or Advanced. The type of Apprentice Pass you have will determine what rewards you can earn.
Starter and Advanced Apprentice Pass

The Starter Pass will be available to all players automatically. You can earn Apprentice Pass Points by completing Daily Challenges and Apprentice Challenges, which earn you rewards from the Starter Pass.
Purchasing the Advanced Pass unlocks an extra layer of rewards for you to earn alongside the rewards from the Starter Pass. Upon completing the Advanced Pass, you can also earn a mighty Epic Champion for your account. The Advanced Pass can only be purchased once per game account.
Daily Сhallenges

There are 4 Daily Challenges that are available through the Apprentice Pass. They are available every day, and always remain the same. These Daily Challenges refresh at 00:00 UTC.
Apprentice Сhallenges

Apprentice Challenges are special, one-time tasks that earn you more Apprentice Pass Points than Daily Challenges. They can be completed in any order. Apprentice Challenges are focused on helping you strengthen your starter Champion - Galek, Athel, Elhain, or Kael.
