Season 9: Theme, Features and New Items
What is the theme of Season 9? The official theme of Season 9 is “Sins of the Horadrim”. The focus is on new powers that you can farm and equip to strengthen your builds. To start the seasonal quest, you must have completed the campaign once.
What is included in Season 9? In past “Campfire Chat” livestreams, the developers talked about the seasonal content and some “quality of life” changes that are coming in Season 9 in Diablo 4:
- “Horadric Powers”: You will receive the powers as usual through a seasonal quest line. You get Arcana by exploring Nightmare Dungeons. The new powers consist of three basic building blocks:
- Catalysts are the basis of your spell
- Infusions change the type of elemental damage
- Arcana change the basic mechanic of the spell
- Horadric Vaults (“Strongrooms”): These mini-dungeons appear in Nightmare Dungeons and contain powerful enemies and strong loot. However, you only have a limited time to complete the dungeons.
- Escalation Nightmare Dungeons: You will be sent through a chain of three connected Nightmare Dungeons, where the affixes stack. But not only does the difficulty increase, so do the rewards. You will receive the seals for the dungeons from vault chests. At the end, you can expect a reunion with Astaroth, a well-known boss from the campaign.
- Horadric Gems: From Qual 1, you will find so-called tomes in the Horadric Vaults. These can be used to craft new, socketable gems. These Horadric Gems will further amplify your spells and bring additional strong bonuses. They are used in amulets and rings.
- New affix types for Nightmare Dungeons: The seals for Nightmare Dungeons also receive new affixes – including “Horadric Reserves”. This gives you access to special chests full of gold, obols, gem fragments, and other resources.
- Updates on loot: Each class receives a new unique in Season 9. Additionally, the item quality from drops varies by difficulty level, as does the drop rate of legendary runes and gem fragments from the hell hordes.
- “Quality of Life” Update: From Season 9 onwards, you can activate the next Nightmare Dungeon directly in the dungeon and continue without detours, saving you time and loading screens. Additionally, the crafting costs for jewel chests are reduced.
Currently, Season 8 is still ongoing in Diablo 4, where you can take advantage of the powers of the hideout bosses:
Season 9: Best Classes & Builds
Which class is the best in Season 9? At this time, it is still unclear which classes and builds will dominate in Season 9. In the current Season 8, especially Necromancers, Druids, and Barbarians are at the top. In our tier list for Season 8, you can gain insight into the strongest builds in the endgame of Diablo 4, including an explanation of what makes the builds so good.
The enormous strength of the builds comes from the combination of various values, for which the overpowering mechanic is in focus. In Season 9, Blizzard wants to counteract this and adjusts the components, as it was not intended that so many builds would benefit from the mechanic.
