Contrary to popular assumption, Capstone Dungeons in Diablo 4 support co-op, effectively allowing players to be carried by their friends if they desire to skip a World Tier or two. The open world in Diablo 4 represents a major departure from the randomly generated maps of past Diablo titles, as not only is the shape of the wilderness a fixed and predetermined path, but it dynamically connects Diablo 4 players across the same World Tier to offer a persistent, yet diverse online experience. While the events which spawn within the many regions of Sanctuary remain randomized, the classic Diablo zone design is reserved for its dungeons.
Dungeons in Diablo 4 represent the meat of its gameplay. Legendary traits for Diablo 4's Codex of Power are obtained by completing certain dungeons, while the endgame thus far revolves around challenging Nightmare Dungeons on a quest for better loot, and tackling the emerging Helltides in the open world. To unlock these features, players must first prove themselves by completing the campaign on either difficulty (Normal or Veteran), and finishing the Capstone Dungeon on the highest difficulty available.
With this understanding in mind, many players expected that Capstone Dungeons would be a solo experience, preventing the unworthy from unlocking the higher World Tiers until they're ready. According to Associate Game Director Joseph Piepiora on Twitter, this doesn't seem to be the case – players will be able to undertake Capstone Dungeons with their friends, regardless of their level. The reception to Piepiora's announcement has been rather mixed, as some fans believe the seemingly difficult Capstone Dungeons from the Diablo 4 closed beta served a logical purpose in personal player progression.
The developers of Diablo 4 likely made the decision to offer co-op Capstone Dungeons to accommodate players who either predominantly progress together, or are trying to catch up with their friends at higher World Tiers. It's a decision that does not impact the endgame experience at all, as players still have to tackle difficult content to be rewarded with better loot. Moreover, the practice of being carried at lower levels has been a cultural cornerstone of Diablo's community, and it is ultimately healthier for the game to offer that option to players in Diablo 4 as well.
It's plain that Blizzard Entertainment is confident in Diablo 4 becoming a huge success, as the company has spared no expense in marketing its flagship title ahead of the June 6 release date. Though some have had their misgivings with the microtransactions system in Diablo 4, the gameplay itself is solid for most of its classes, and the story evokes an atmosphere that truly hearkens back to Diablo's darker roots. Though its campaign will keep players entertained for a month or two, the quality of its online experience will ultimately decide the game's long-term success.
Diablo 4 launches on June 6 for PC, PS4, PS5, Xbox One, and Xbox Series X/S.
