Challenges in Path of Exile: Sentinel

In the Sentinel league, we're revamping our challenge system, giving you harder challenges to complete in order to earn even greater rewards. There are still 40 challenges but you'll start earning pieces of the Ophidian and Ophidian Lord Armour Sets and Wings from as early as six completed challenges. Completing challenges also grants you pieces of the Sentinel Totem Pole Hideout decoration!

To give you an idea of what to expect from the challenges, we've included the details of all 40 challenges in the Sentinel league for you in this news post. You can also check out the challenge rewards in the video below.
