Diablo IV is the latest entry in the Diablo series, and Blizzard regularly updates the game with new features, balance changes, and fixes to keep theplayer counthigh. You can find patch notes attached to each update, which we have listed below.
GAMEPLAY UPDATES
Vampiric Powers
Developer’s Note:Select Vampiric Powers from Season of Blood have returned with some tweaks to make their power level fit into Season of the Construct. These powers will be available as Legendary Aspects in all World Tiers and in both the Eternal and Seasonal Realms.
Book of the Dead
Skills
Developer’s Note:The goals of this change are to reduce the opportunity cost of using Blood Surge against fewer numbers of enemies as well as increasing its overall power, even in scenarios of hitting multiple enemies.
Unique Items
The Seneschal
Developer’s Note:We want the Seneschal to feel strong, but there are certain powers that are overperforming. Additionally, there are a couple of unintended interactions that are being addressed.
BUG FIXES
Gameplay
Developer’s Note:Some items, Legendary Aspects, Passives, Paragon bonuses, and Skills displayed bugs that allowed players to gain more power than intended when you equipped and then unequipped them. We believe these interactions lead to a worse experience for all players, as it creates a stigma that these bugs must be exploited to reach new levels of power. The bug fixes below address all known instances of this issue.
GAME UPDATES
Uber Unique Crafting
Developer’s Note:Uber Unique items are highly sought after. With Season of Blood, we introduced target-farming Uber Unique Items with Uber Duriel to gives players another source of acquiring this type of item. However, we want to give players increased autonomy in obtaining their desired Uber Unique by addressing feedback that expressed how acquiring duplicate or undesired Uber Unique Items lessens that feeling of triumph. A new system empowers players to make use of duplicate and undesired Uber Unique items by salvaging them for a new resource which can be used to eventually craft an Uber Unique of their choosing. Additionally, the chance for Uber Unique Items to drop everywhere but in Uber Duriel encounters has been increased.
Echo of Malphas
Developer’s Note:We have noticed players tended to use their Pearls of Warding for fighting Echo of Malphas instead of on Zoltun’s Warding. We are adding in Igneous Cores—a new item used solely to summon Malphas instead of Pearls—so players don’t have to choose between extra protection in the Vaults or fighting the boss. Additionally, we have made the fight against Malphas more difficult but also increased the rewards it provides.
Developer’s Note:We’ve received feedback that the Seneschal does not feel powerful. The Seneschal becomes more powerful as it reaches max level, but we have noticed that many players have not had the chance to level up their Seneschal enough to experience this. We are introducing multiple changes to ensure players have more sources to earn Governing and Tuning Stones from so they can level up their Seneschal and unlock their new companion’s full potential.
Vaults and Arcane Tremors
We have made multiple quality-of-life changes to the player experience in the Vaults and Arcane Tremors.
Diablo IV 1.3 Release Notes - Build #49213 May 07, 2025
CLASS UPDATES
Developer’s Note:It’s important to us that when a player chooses to fully invest in a Skill, the payoff is immense. In pursuit of this goal, several of our new Unique and Legendary items are targeting Skills that have yet to reach their full potential. We’re excited to see what players accomplish with our new Unique items for Barbarian’s Rend, Druid’s Lightning Storm, and Sorcerer’s Meteor. We’re also targeting some pressing issues for each Class. Necromancers with Cult Leader should see their Minions strike a bit harder, Barbarians shouldn’t feel that 3 Shouts are a requirement for their success, and Sorceresses applying Vulnerable with Lightning Spear should open new build opportunities. There are also Class updates to items and Skills that are underperforming, such as the Rogue’s Ranged Unique Items, and the Necromancer’s Golem.
Ring of the Ravenous
Gift of the Stag
Aspect of the Unsatiated
Item Updates
Bladedancer’s Aspect
Developer’s Note:This change was made to properly match the visuals of 2 rotations around the player.
End-Game Activities
Items
Developer’s Note:World Bosses are intended to reward powerful loot for your level. With this change, at a high level, players will see maximum Item Power gear from World Bosses at higher levels.
Miscellaneous
User Interface and User Experience
Developer’s Note:The new Respec options allows players to easily refund or re-add their Skills in a flexible way. Our goal with these additionsis to make purchasing and refunding Nodes less time consuming while encouraging players to experiment more.
Rogue
Sorcerer
Developer’s Note:Ball Lightning was dealing an unintended amount of damage because of its Enhanced upgrade. This bug fix returns the amount of damage done by this Skill to intended quantities.
Diablo IV 1.2.3 Release Notes - Build #47693 Jun 28, 2025
Developer’s Note:After reviewing gameplay data and player feedback, we recognized that completing higher Nightmare Tiers was not as rewarding as we initially hoped for, with many players stopping their journey after reaching Tier 50. The experience increase to Glyphs at higher Tiers was made with the intent of incentivizing players to push their builds, making their arrival at Tier 100 feel that much more fulfilling. We will monitor how this change in experience pans out for players and encourage you to provide us with any feedback you have around this system.
Season of Blood
Developer’s Note:A previous Hotfix allowed players to walk through Blood Wells to access Potent Blood. This change reverts the ability to walk through Blood Wells, but in exchange, Potent Blood will no longer spawn in the middle of Blood Wells so it can be easily picked up.
Developer’s Note:If they choose to play through the Campaign, players that haven’t yet unlocked Mounts must complete the Donan’s Favor quest to unlock them. If the campaign is skipped, you must reach Level 25 before unlocking Mounts. The tooltip previously mentioned Quest completion only, which is irrelevant when skipping the Campaign.
Malignant Rings
Five new Unique Rings have been added to the game, one for each class. These are based on popular Malignant Powers from Season of the Malignant, and are immediately available in both Seasonal and Eternal realms.
Developer’s Note:Creating the Malignant Rings are a way for us to take popular Seasonal content that resonated with Players and reintroduce it in a way that can persist beyond the Season and into the Eternal realm.
The following adjustments have been made for the Sanguine Battery Event.
