Chaos perks are the newest seasonal power introduced by the developers of Diablo 4 during the 2.4.0 Public Test Realms (PTR), which will be open for testing from August 19, 2025, to August 26, 2025. These Chaos perks will be available in four rarities: Magic, Rare, Legendary, and Unique. You will be able to equip one Unique and three Non-Unique perks at a time.

Each class of Diablo 4 will be getting 12 generic perks and four class-specific perks of every rarity. While some of the perks' modifications are straightforward, others can completely block out certain stat brackets and force you to build around the new logic.

All universal Chaos perks

Players will have access to 12 universal perks and 4 class specific pers to experiment with in Season 10 (Image via Blizzard Entertainment)

Magic category

1) 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.

This perk can be great for builds that revolve around expensive core skills like Bash/Upheaval, Pulverize/Tornado, etc., for a much larger resource pool.

2) 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.

This is a great choice for builds with a ton of Lucky-Hit modifiers that can randomly deal some serious damage while getting a cooldown reduction from that damage output.

3) 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.

This can be a great filler for builds based around Utility and Core skills, especially if it's built around Crit scaling or Overpower.

---

Rare category

1) 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.

Builds with a single damage type (fire, poison, chill, etc.) can heavily benefit from this perk, allowing them to deal massive burst damage of their highest damage type.

2) 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.

This can be a solid perk to craft your core-focused build, but the build must have a ton of resources in storage.

3) Alternating Alterations

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

Builds revolving around a dual-core skill setup can heavily benefit from this perk, allowing for increased damage output as well as resource management.

---

Legendary category

1) 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.

This high defense perk is perfect for builds that crafted around barrier or Fortify generation, allowing for greater sustainability.

2) 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.

This can effectively be a game changer for many builds in Diablo 4, especially if they are using skills with short cooldowns.

3) Crazy Brew

• Your Healing Potion is infused with the power of Chaos, granting you 100% Resource Cost Reduction, 40-80%[+] increased Attack Speed and 40-80[+] increased Movement Speed for 4 seconds.
• Your Healing Potion has a 10 second Cooldown and you can drink it at full Life.

This effectively turns your Health Potion into a damage multiplier, perfect for clearing boss phases at the risk of life pool management.

---

Unique category

1) 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.

This chaos perk is extremely effective for boss-melting builds that can quickly feed stacks for complete utilization.

2) Brawn Over Brains

Gain the following:

• 100-200% [x] Maximum Life
• +50-100% Healing Received
• 50-100%[x] Overpower Damage
• However, your Maximum Resistances are reduced by 25%, and your damage reduction from Armor is capped at 60%.

This will be a godsend if you're using Overpower-based builds in Diablo 4.

3) A Beast Cornered

• For every 10% Life you are missing, you gain 10-20% [x] increased damage and 5% damage reduction.
• Spending Resources also drains a percentage of your Life equal to 30% the Resources spent, refunding those Resources. This cannot reduce you to below 10% Life.

If you are experimenting with builds that run life-steal skills and can maintain stability in low-health conditions, this perk can be a game changer in Diablo 4.

2) Purge the Infected - Rare

• Your Core Skills also apply 100-200% of their Base damage as Poisoning over 4 seconds. Dealing direct damage to a Poisoned enemy spends 5 Spirit to be a guaranteed Critical Strike.

Necromancer

Builds with exceptionally high Crit scaling, can heavily benefit from this perk.

Run this perk beside Chaotic Cooldowns to fully utilize builds that use corpses as a source of damage output.

• Your base Core Skills are now empowered as Ultimate Skills, cost no Essence, but have a 30-20 second Cooldown.

Can be paired with Alternating Alterations to create Core skill synergy, while Stun Grenades creates a cast window.

4) Hit and Run - Unique

• Every 15 meters you move grants you 30-50%[x] increased damage for 5 seconds. This bonus stacks, but does not refresh. If this bonus is not active, you deal 30% reduced damage.

This allows for a high-mobility, high-damage-dealing build but can be extremely resource hungry. Pair it with Crazy Brews to passively generate resources.

---

Sorcerer

1) Explosive Combinations - Magic

• Casting a Basic Skill increases the damage of your next Core Skill Cast by 30-50%[x] stacking up to 3 times.

This perk effect is simple, and any build of the Sorcerer class made around basic and core skills can benefit from using it in Diablo 4.

2) Advanced Techniques - Rare

• Your base Core skill ranks increase their Mana Cost or Cooldown by 10% and further increase their damage by 10-20%[x].

While this perk can increase the casting cost significantly, pairing it with Crazy Brews and Invigorating Attacks can neutralize the penalty significantly.

• Your Conjurations are empowered and deal 10-30%[x] increased damage, but each one drains 5 Mana per second.
• Ice Blades attacks burst in an area around the target.
• Lightning Spear hits have a 10% chance to spawn static Ball Lightnings.

• You gain 200-400% increased Maximum Mana, and each point of Intelligence increases your Maximum Mana by 1.

This perk turns your Mana pool into armor by taking away 99% of your maximum life, so investing in Defensive skills like Ice Armor and barriers is a must. The massive mana pool gained from this perk can be a fantastic resource for repeated skill castings for Sorcerers in Diablo 4.

---

Spiritborn

1) Alacrity - Magic

• Your Basic Skills gain 10-30%[+] increased Attack Speed, their dash range is increased by 50% and their 3rd attack now happens every 2nd attack.

This is great for Basic skill-based spiritborn builds.

• Your base Core Skills hit additional times in a larger area for 20-40%[x] increased damage but also have a 10 second cooldown. Your Basic Skill’s 3rd attack resets the cooldown on your Core Skills.

Builds that revolve around Core-Basic skill rotations can heavily benefit from this Chaos perk in Diablo 4.

3) Back Off! - Legendary

• When Casting a Skill, it deals 30% reduced damage to enemies who are Close to you when you Cast and 100-200%[x] increased damage to all other enemies.

This perk allows you to lean towards a more mid- to long-range playstyle with massive damage output towards distant enemies in Diablo 4.
