Season 10: Theme, Features, and New Items
What is the theme of Season 10? The official theme of Season 10 is “Hellish Chaos.” The focus is on chaos, which runs through various contents and even items. There will be new Chaos-uniques and Chaos powers that expand your builds.
This is what Season 10 includes:
- Chaos powers: The Chaos advantages are the seasonal mechanics and change the functions of your skills. There are 4 different rarity levels (magic, rare, legendary, unique), and you can equip 3 non-unique and 1 unique at the same time. There are 16 general Chaos powers and 4 class-specific ones.
- Chaos portals: Chaos portals can spawn throughout Sanctuary – for example, in the Hell Flood and in certain Nightmare dungeons. If you kill the monsters, you can expect loot. On Torment levels, you get additional XP, gems, and Chaos-uniques. In rare cases, you may even discover mythical Chaos portals on Torment levels.
- Chaos-uniques: The new Chaos armor is a stronger version of existing uniques. Their counterparts drop for other item slots, creating entirely new paths for builds and playstyles. You can only equip one version of a unique, thus you cannot combine the normal version with the Chaos version.
- Overhaul of the Hell Hordes: Blizzard has revamped the gifts you choose between the waves in the Hell Hordes. They are meant to feel like a valuable choice. Additionally, there will be Chaos monsters and occasional Chaos waves that should spice up your run. They are significantly harder, but also provide more Ether. Moreover, at the end, you can optionally fight against “Bartuc, the Warbringer of Blood” instead of the Cruel Council.
- Transient Hell Hordes: There will be a modified tier of Hell Hordes that you can run through even before the Torment levels.
- New uniques for all classes: In Season 10, new uniques for the six classes in Diablo 4 will be introduced again. New Mythic uniques are not planned as of now.
- “Quality of Life” changes: On the PTR for Season 10 in Diablo 4, players discovered that the seals for Nightmare dungeons have a new symbol. This is the symbol for “Whisper” – that is, tasks you complete for the Tree of Whispers. Additionally, players reported that bosses apparently no longer have immunity phases, but only moments when they are fortified.
Season 10: Best Classes & Builds
Which class is the best class in Season 10? At this time, it is still unclear which classes and builds will dominate in Season 10. While players can currently get an impression on the PTR, the developers will certainly make further adjustments at the start of the season.
