Diablo IV’s ninth season, titled Sins of the Horadrim, launches on July 1 and brings new content centered on the history of the Brotherhood of the Horadrim.
Players will be tasked with purifying blood-tainted relics corrupted by Astaroth and facing a new sequence of challenges in reworked areas of the game.
New questline focused on Donan and Bryona
The season introduces a new storyline featuring the druid Bryona, who returns to Cerrigar to confront the consequences of decisions made by the Horadric mage Donan.
Alongside her, players will explore the Horadric Strongroom, uncovering long-buried secrets and facing demonic threats.
Customizable Horadric spell system
One of the season’s major additions is the introduction of Horadric Spellcraft. This new system allows players to combine different elements to create customized magical abilities tailored to their playstyle. The feature adds a new layer of strategy to spellcasting during combat.
Permanent changes to Nightmare Dungeons
Three new mechanics are being permanently added to Nightmare Dungeons:
- Horadric Strongroom: Small dungeons found within Nightmare Dungeons. They offer tougher enemies and superior rewards, including mummified foes and exclusive encounters.
- Escalating Nightmares: A chain of three consecutive dungeons with escalating difficulty and increasing rewards. Upon completing all three, players face Astaroth in his Exalted form.
- New Astaroth encounter: During the boss fight, Astaroth separates from the creature known as the Amalgam of Rage, resulting in a dual-boss encounter. The Amalgam can return to the fight if Astaroth is not defeated quickly, requiring players to adopt a more tactical approach.
Additional new features
Season 9 also introduces official mouse and keyboard support for consoles, along with new Unique items for all playable classes, offering greater build diversity and customization.
Season Journey rewards
By completing objectives in the Season Journey: Sins of the Horadrim, players can unlock cosmetic and functional rewards. These include Dante, a companion dog that follows the character and can be summoned as an in-game pet.
