Diablo IV's Season 3 will add a new endgame activity in the form of a weekly challenge dungeon called The Gauntlet, which will see players competing to earn the top spots on the game's leaderboards for both fame and exclusive cosmetic rewards.

The mode sounds similar to Diablo III's Challenge Rifts, although players participating in The Gauntlet in Diablo IV Season 3 will be bringing their own characters and builds into the dungeon this time around. Each week, all players will compete by running the same "fixed seed linear dungeon" to earn high scores, with speed and efficiency being of the essence. The Gauntlet is on a timer, and killing enemies and completing the dungeon quickly will earn players points that contribute to their score. To encourage efficiency, loot will only drop at the end of The Gauntlet and not from defeated enemies along the way.

There will be separate leaderboards across the game's classes, as well as for hardcore characters, solo runs, and group runs. Players earning top scores will be rewarded with Seals, special cosmetics that can be applied to character portrait frames to show off their accomplishments. Each week The Gauntlet leaderboards will be wiped, but the best-of-the-best will see their scores recorded in the Hall of Ancients, a persistent leaderboard that doesn't reset.
