The public test for Diablo 4 Season 11 kicks off on the 22nd (KST), giving players an early look at a massive overhaul involving the itemization, monster combat, and progression systems.

The public test server (PTR) will be live for roughly a week, running from 2:30 PM on the 22nd until 3:00 AM on the 29th for PC players. The highlight of Season 11 is the 'Celestial Power Infusion' accessed via 'Consecration', allowing you to bolster your gear with extra Legendary powers.

And yes, the classic high demons are making a comeback. Azmodan makes his grand debut as a new world boss, while Duriel, Belial, and Andariel return with fresh, devious mechanics. You can summon Azmodan via beacons; Duriel will corrupt the Helltide with parasitic maggots; Belial manipulates the Pit with illusions and shifting boss encounters; and Andariel haunts the Kurast Undercity, complete with time-draining shadows.

The itemization system is also getting a proper rethink. You'll have far more agency now: 'Tempering' lets you hand-pick specific attributes through recipes, and 'Masterworking' allows you to truly elevate the quality of your hard-earned loot.

As for the monster combat, it has been redesigned to be far more tactical. Expect foes that behave with actual intelligence, with clearer roles and improved elemental diversity that should make every skirmish feel significantly more dynamic.

Finally, we have 'The Tower', a new time-attack dungeon challenge, and the 'Leaderboards'. The Tower is a multi-layered gauntlet built around the new combat system; you have 10 minutes to clear floors and down the final boss to etch your name onto the leaderboard. Keep in mind, this is currently a beta version that will evolve over future seasons.
