Diablo 4 is about to begin a PTR test for Season 10 next week, and the patch notes for it have been released in advance. The PTR itself will run from August 19 to 26, where you can sample the seasonal power flavor, which - this time - is Chaos Perks and Chaos gear. To join the PTR, you can select the Public Test Client from the drop-down tab above "Play" while Diablo IV is selected on Battle.Net.
But before you get started with that, here are all the balance changes as well as new Items introduced in Diablo 4 Season 10, so you can theorycraft your builds during the weekend. Testing out builds is even easier in this PTR because Mrak (the PTR-exclusive boost vendor) has received a few new tools, such as segmented boost choices.
Before we dive into the patch notes, one big change to note is that Infernal Hordes has been given a facelift.
Specifically, the Monsters in the Infernal Hordes had their stat adjusted, and more importantly, the Infernal Offerings have been significantly changed in some cases to make them more exciting. This is because Chaos Waves, one of the new seasonal mechanics, is tied to Infernal Hordes. Check out details on Chaos Powers, Chaos Armor, and Infernal Hordes Reborn here.
Meanwhile, here are all the new uniques in Diablo 4 Season 10.
