Diablo 4 2.4.0 PTR Update: Everything You Need To Know

News
Updated on Aug 17, 2025
Aug 17, 2025

Overview

The 2.4.0 Public Test Realm (PTR) for Diablo IV will be available from August 19-26.

Welcome to the 2.4.0 Diablo IV update. In this article, we will break down all the major changes and tell you what you need to know in the latest update for D4!

Infernal Hordes Reborn

Internal Offerings are being redesigned to make your choices more meaningful. You will also now start each run with an Infernal Offering to help you get started.

The Fell Council

A member is now a Council Speaker and gains stronger abilities.

Chaos Monsters

A new family of enemies that grants shrine-like buffs when killed.

Chaos Waves

Within the Infernal Hordes, you’ll have the option to now face off against higher-difficulty waves. They grant better rewards, so it might be worth fighting them!

Bartuc, the Warlord of Blood

A new optional boss. You can face Bartuc instead of the Fell Council.

The Fleeting Hordes

A modified version of the Infernal Hordes. There are a total of 4 waves in the early game, and you’ll eventually fight 2 Fell Council members.

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 party member has to spend Aether and the first player to decide chooses the decision for the whole group.

Bartus will harness Chaos Portals to fire projects, and players must learn these moves for an advantage.

After defeating Bartus, the rewards drop directly on the ground, so no need to spend Aether to claim them.

Harness Entropy with Chaos Armor

A unique new Armor type called Chaos Armor has entered the Sanctuary. They’re more powerful versions with unique twists.

They can appear from the following item slots:

  • Helm
  • Chest
  • Gloves
  • Pants
  • Boots

They always drop at max power, come with at least 1 greater affix and are always stronger than the standard versions. You will however be unable to equip the same unique item between standard and chaos versions.

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.

  • Unique

You can equip 3 non-unique Perks and 1 Unique Perk at once. Additionally each class has access to a set of perks that are exclusive to them. There are 16 perks for each class: 4 rare and 4 class-specific.

The following are class agnostic Chaos Perks:

Magic

Invigorating Attacks: Every 5 seconds, your next Basic Skill generates an additional 50-100% of your Maximum Primary Resource, but your Basic Skills deal 30% reduced damage.

Accelerating Chaos: Lucky Hit: Damaging an enemy has up to a 10% chance to trigger a Chaotic Burst on the enemy, dealing 200-400% damage. Your Chaotic Bursts that hit an enemy reduce a random active Cooldown by 0.5 seconds.

Unstable Power: Chaotic magics erupt from your Basic Skills, making them guaranteed to Critically Strike and Overpower for 50-100% increased damage, but the power is unstable, giving them a 3 second cooldown.

Rare

Erupting Chaos: Chaotic Bursts randomly erupt around you, dealing 200-400% damage of your highest damage type. Your Chaotic Bursts also deal 100% of their initial damage over 4 seconds.

Power Siphon: Your Core Skills deal 50-100% increased damage, but also reduce your Maximum Current Resource by 20 for 6 seconds. This reduction stacks but does not refresh.

Alternating Alterations: Casting a Corse Skill empowers your next non-Channeled Cast of a different Core Skill, refunding 50% of its Resource cost and dealing 10-30% increased damage.

Legendary

Marred Guard: You can no longer be healed above 50% Life. You gain 5-10% Maximum Resistance to All Elements, +20-40% Armor, and 50-100% increased Barrier and Fortify Generation.

Chaotic Cooldowns: Casting a Skill with a Cooldown will randomly set its Cooldown between 2 seconds and its base cooldown. You no longer benefit from Cooldown Reduction. Using a Cooldown unleashes a Chaotic Burst, dealing 300-500% damage of your highest damage type.

Unique

Chaos Unleashed: Killing an enemy generates 2 stacks of Chaos and dealing direct damage to a boss generates 5 stacks of Chaos. At 100 stacks, unleash a salvo of 9 Chaotic Bursts, dealing 300-500% of your highest damage type.

Your Chaotic Bursts gain 20%[+] Critical Strike Chance, and deal 50-100%[x] increased damage.

Brawn Over Brains:
