This is the first Season for Diablo IV, categorized as a 'Season' update, focusing on temporary narrative and gameplay additions. You investigate a new corruption, hunting 'Malignant Monsters' to harvest build-altering 'Malignant Hearts' with the help of Cormond. Progression involves completing the Season Journey for rewards like skill resets and climbing the 90-Tier Battle Pass for temporary Season Blessings that boost XP or Gold. This content complements the core experience, offering a focused, time-limited adventure available on PC and consoles.
The central theme revolves around the "Malignancy," a corruption infecting the armies of the Burning Hells. The primary gameplay loop introduced involves hunting down these Malignant Monsters to harvest their core—the Malignant Hearts. These Hearts are not merely loot; they are converted into powerful, build-altering powers that players can utilize for the duration of the season.
The narrative progression involves assisting Cormond, who trains players in the specific mechanics required to capture and utilize these Malignant Hearts. The overarching goal is to trace this corruption back to its source before it fully overwhelms Sanctuary.
The introduction of Malignant Hearts is the defining mechanical feature of this season. These function as unique, temporary power sources that can significantly alter character builds, offering new avenues for experimentation outside of standard gear and skill progression.
Progression is structured around two main systems:
Rewards earned from the Free Tiers of the Battle Pass include Smoldering Ashes. These Ashes can be spent on Season Blessings, which grant temporary bonuses to the acquisition rates of Experience, Gold, or Obols. These specific bonuses are active only until the conclusion of this specific season.
This seasonal content is available across all platforms where the parent game resides, including PlayStation 5, PlayStation 4, PC (Microsoft Windows), Xbox Series X|S, and Xbox One. As a seasonal update, it functions as an episodic addition to the main game, rather than a standalone title or a permanent expansion.
This update focuses entirely on the seasonal narrative, mechanics, and progression systems described above. It is structured as a time-limited event complementing the ongoing world of the core game.
