The 2.4.0 Public Test Realm (PTR) for Diablo IV will be available from August 19—26, offering you the chance to test upcoming changes and features releasing with the next season for the base game, along with some Vessel of Hatred updates.

The purpose of the PTR is to test updates and features before the launch of the next season, where we’ll be focusing on formidable Chaos Amor, Chaos Perks, and a revamped Infernal Hordes.

Then, using your feedback, we’ll make some adjustments before our next season goes live. The feedback we receive helps us to fine-tune balance changes, eliminate bugs, and create the best experience possible while testing new systems. Thank you for playing through the PTR, testing new features, and providing feedback to the team.

Here is what the 2.4.0 PTR will preview ahead of next season.

Infernal Hordes Reborn

The Infernal Hordes are hotter than ever; we’re dialing up the intensity on this incendiary mode.

Infernal Hordes refined

We’ve done a significant re-work of Infernal Offerings revealed between each Wave. Our goal is to try to make all offerings feel valid as choices for you as you start to stack them to focus on your run.

We’re doing this by balancing existing offerings, changing the effects of some offerings, and adjusting base Monster populations.

At the start of the Infernal Hordes, you’ll now start with an Infernal Offering to immediately stoke the embers and breathe some fire into your run.

The Fell Council

The Fell Council has had some promotions. When fighting them, one of their members will now be the designated Council Speaker, and gain enhanced abilities.

Chaos Monsters

Hell has unearthed a new monster family from deep its horrid maw. Born of smoke and brimstone, these Chaos Monsters provide a powerful shrine-like buff when killed.

Chaos Waves

Hellfire brews the dastardliest maladies. Within the Infernal Hordes, you’ll occasionally be offered the choice of a Chaos Wave within the Infernal Hordes from your Infernal Offerings. You can expect an amount of Chaos Waves offered relative to the Infernal Compass Tier each time you enter the Infernal Hordes.

Chaos Waves completely alter the upcoming wave, imbuing havoc and intense challenge. These waves will have significantly increased difficulty, but reward far more Aether should you be able to survive.

Chaos Waves will have many different combinations to discover and master. Dodge deadly projectiles from Chaos Rifts, slay a rampaging Hellwyrm, or hunt down erratic Aether Goblins. Chaos awaits!

Fight Bartuc, the Warlord of Blood

Rather than facing off against the Fell Council, you can choose to risk your hard-earned Aether and throw down against the insidious, reborn Bartuc to complete your Infernal Hordes run.

The Fleeting Hordes

We’re introducing a warming version of the Infernal Hordes to burn through earlier in your character journey.

In Pre-Torment Tiers, you’ll play this modified version of the Infernal Hordes to slay through before reaching Torment difficulties.

Fleeting Hordes will be 4 waves in total, with limited Infernal Offerings to keep the packs of vicious Goblins under control.

Upon completing the 4 waves, you’ll fight two Fell Council members before you can spend your hard-earned Aether for rewards.

Bartuc Beckons

An infamous Vizjerei Warlord known for his acts of cruelty performed in the Mage Clan Wars, Bartuc’s perversion knows no bounds. He returns to Sanctuary with a new title, Warlord of Chaos.

Each member of your party will need to spend Aether to fight the infamous Vizjerei, Bartuc who was once known as the Warlord of Blood. The first player who chooses sets the decision for the rest of the party.

Bartuc will harness Chaos Portals to shoot projectiles at your location, master his tactics and enter these Chaos Portals tactically to gain the upper hand.

Upon defeat, Bartuc’s rewards will appear on the ground, so you do not have to spend additional Aether to claim these spoils.

Harness Entropy with Chaos Armor

The only certainty is that nothing is certain. No entity is free from Chaos’s grasp—human, Horadrim, Angel, or Demon. All dance in its path, so rather than succumb to its erratic forces, harness this untapped power for yourself.

A new Unique Armor type—Chaos Armor—has entered Sanctuary.

Chaos Armor is a more powerful version of existing Unique items that come with a diabolical twist. Chaos Armor are Unique items that appear as more powerful counterparts for other Item slots, leading to entirely new ways of dispensing carnage. Chaos Armor can appear for the following item slots:

Helm

Chest

Gloves

Pants

Boots

Chaos Armor will only appear as an item fit for anything other than its original slot. For example, Flickerstep won’t have a Chaos Armor version in the Boots slot.

Chaos Unique Powers are also more potent than their normal counterpart, always appear at Maximum power, and have at least one Greater Affix.

Note: you won’t be able to equip the same Unique item between Chaos version and standard.

For example, you could have Fists of Fate drop as a Helm instead of as Gloves, allowing you to equip a different set of Unique Gloves to compound those affixes in a combination that was previously unavailable.

The following Uniques will be available as Chaos Unique:

Seal Chaos Rifts

Strange portals of crackling energy have appeared across Sanctuary, unleashing the Burning Hells’ legions through their open maw. Chaos Rifts materialize in a few different ways:

Chaos Rifts will appear in the open world of Sanctuary within Helltide. Kill the demons pouring from them and seal them away for a variety of rewards. They’re a great source of chaotic loot, giving you additional experience, gems and Chaos Armor in Torment difficulties.

In extremely rare cases, when playing in Torment difficulties you may even come across a Mythic Chaos Rift.

Chaos Rift Nightmare Dungeons

These Nightmare Dungeons are rife with Chaos Rifts, these are bountiful sources of Fleeting Hordes Compasses.

Wield Chaos Perks

Something incredible has descended upon Sanctuary, imbuing your abilities with devastating effect. Chaotic magic distorts all that it touches, even you! Chaos is of course, chaotic, and these Perks often come at a price for the power they provide.

Chaos Perks change how your Skills function, harness your finest buildcraft to create devastating combinations.

There are 4 different rarities of Perks:

Magic

Rare

Legendary

Unique

Additionally:

You can equip 3 non-Unique Perks at once, and 1 Unique Perk.

In addition to the Perks every class can use, each class has access to a set of perks that are exclusive to them.
