What Are Seasons?
Seasons are an optional, recurring game mode that offers PC players the opportunity to periodically start fresh, leveling new Normal or Hardcore heroes from level 1 without any currency, resources, items, or previously earned Paragon experience. Similar to the separation between Normal and Hardcore game modes, Seasonal heroes will also have their own shared stash and Artisan progression. Any currency, materials, recipes, items, Paragon experience, and Artisan progression earned during a Season will be rolled over to a player's non-Seasonal profile once the Season concludes.

Season 4 will offer unique rewards and new challenges for players, including new Legendaries, an exclusive Transmogrification set only available to those who compete in each Season, and Season-only achievements called Conquests. Progress within a given Season will also be tracked on the Leaderboard system, and in the brand new Seasons Journey interface. To learn more about Season 4, click here.
Good luck, nephalem! May the loot gods treat you kindly and your deeds of valor always be remembered.
