Diablo 4, the upcoming action RPG, is expected to follow a live-service model similar to its predecessors, Diablo 2 and Diablo 3. This model includes regular expansions and the addition of new classes over time. Considering Blizzard's history with Diablo 3, it is highly likely that a sixth class will be introduced in Diablo 4.
Speculations suggest that the game may introduce the Paladin or Templar classes from previous Diablo games as potential additions. These classes would fulfill the need for a heavily-armored option and a holy magic wielder, both of which are currently absent from the playable classes in Diablo 4. However, an unexpected but fitting addition could be a Death Knight or Hell Knight, which would fulfill the armored archetype and align with the darker tone of Diablo 4.
While Diablo 4 launches with five classes, it is probable that additional classes will be introduced in future updates or expansions, possibly tied to the game's seasons. And you can buy Diablo 4 gold to help you progress the game. Although the first season of Diablo 4 may not include a new class, it is reasonable to expect the game to expand within its first year, prompting the introduction of a fresh perspective through a new playable archetype. Despite the limited options due to existing archetypes in the game, the prospect of a sixth class remains exciting.
The existence of a sixth class in Diablo 4 has potentially been confirmed by a leaked image found on the official Diablo Displate page, showcasing the five known classes along with a mysterious sixth class.
The most likely candidate for the sixth class in Diablo 4 is a Holy Shieldbearing class, reminiscent of the Paladin or Crusader, which have previously fulfilled this role in Diablo games. The Paladin or Crusader archetype, which gained popularity in Diablo 2 and Diablo 3, aligns with the series' theme of defeating demons and protecting the land from evil. This choice offers a distinct playstyle compared to the existing Diablo 4 classes and makes sense from a lore perspective. It could be used to expand upon seasonal storylines, complementing the game's emphasis on the live-service model Blizzard has been implementing.
While the Paladin or Crusader is the most probable option for the sixth class, it is not the only one. Another potential archetype that could fit well in the world of Sanctuary is the Amazon. Introduced in Diablo 2 and recently reintroduced in Diablo 2: Resurrected, the Amazon brings a unique aspect to the game through her proficiency with the javelin. With a focus on ranged combat, the Amazon would be a valuable addition to Diablo 4, particularly considering the predominantly melee-oriented gameplay. Although some similarities exist with the Rogue class, the Amazon's introduction would offer a fresh and distinct experience, especially since it skipped Diablo 3.
Lastly, the Monk, a fan-favorite class from Diablo 3, could also be a suitable addition to Diablo 4. With a background similar to that of the Paladin and Crusader, the Monk would seamlessly fit into Diablo 4's Sanctuary and the ongoing war between angels and demons. While also being a melee-centered class, like the Barbarian and Druid in Diablo 4, the Monk would bring intriguing options for gear and abilities. Additionally, it could enhance the game's mobility aspect, providing value to classes with limited mobility options. The Monk's presence would contribute to the game's identity while retaining its unique qualities from Diablo 3.
