Following the recent public beta test weekends, Blizzard has unveiled the initial patch notes for Diablo 4. These patch notes encompass various improvements such as enhancements to the game's user interface and controls, balancing adjustments for all the classes available in Diablo 4 upon release, and significant revisions to enhance the overall dungeon exploration experience.

Diablo 4 mid-April Pre-Launch Update Patch Notes:

Dungeon Layouts

One of the most common pieces of feedback we received is that players felt they were doing a lot of backtracking within certain dungeons. We have optimized multiple dungeons across all zones to minimize the need for backtracking. Here is a list of dungeons specifically in the Fractured Peaks zone which received layout updates:

Caldera Gate
Defiled Catacombs
Derelict Lodge
Forbidden City
Hoarfrost Demise
Immortal Emanation
Kor Dragan Barracks
Maulwood
Rimescar Caverns


Dungeon Events

The chance for an Event to spawn inside of a dungeon has increased from 10% to 60%.


Dungeon Gameplay

To reduce the need to backtrack, small numbers of straggling monsters will seek out the player to help complete the Kill All Monsters objective.
When Animus is gathered, the player and nearby allies will:
Gain 10 Resource.
Reduce all active Cooldowns by 1 second.
Depositing Animus channel time was reduced from 3 to 0 seconds.
The time to Rescue was reduced from 3 to 1.5 seconds.
All Rescue objectives now drop a Health Potion upon completion.
While carrying the Ancient's Statue, Bloodstone, Mechanical Box, or Stone Carving, you will receive a Momentum bonus granting a 25% move speed increase to you and nearby allies.
Pedestals have had their channel time reduced from 2 to 0 seconds.
Returning a Portable Object to its Pedestal now fully restores Health, Resource, Potions, and resets cooldowns for all nearby players.
All doors will now generate a minimap ping when they are opened.
All Structure Objectives in dungeons now have additional combat mechanics players must overcome.


Developer’s Note: While our dungeons offer a variety of Objectives to complete, player feedback stated that the action of completing each Objective felt tedious. We hope that providing bonuses, such as the increase to mobility while carrying certain Objective items, will streamline and vary the experience of completing Objectives. This adjustment is merely a starting point, and we intend to extend this philosophy to keys in a future update.

General Class Gameplay:

Effects like Stun and Freeze can be applied to Elite Monsters twice as long before they become Unstoppable.
Reviewed class skills to confirm that all classes have access to sufficient skills that remove control impairing effects.
Many Legendary Powers have had updates to their effectiveness.

UI

Fixed an issue where the built-in Screen Reader was not reading key prompts, game options details, and other UI text.
Fixed an issue where actions could not be bound to the mouse wheel.
Fixed an issue where Evade couldn’t be bound to the right Analog Stick on controller.
Chat will now display on the left side of the screen when using the centered action bar configuration.
A character's stats will be displayed by default when players click the Materials & Stats button within their Inventory.
The Move and Interact inputs can now be mapped to one button while the Primary Attack input is mapped to a secondary button.
The sans serif font used in-game has been replaced with a new serif font.

Encounters

Fixed multiple issues that allowed bosses, like the Butcher, to become unresponsive.
The Butcher has been re-evaluated for difficulty and will present a greater challenge in World Tiers III and IV.
Bosses such as T’chort, Malnok, Vhenard, and others were reevaluated for melee character difficulty, resulting in attacks and fight mechanics changes.
Fixed an issue where Vampire Brutes using the Shadow Enchant affix would chain-cast Impale.

Cellars

Increased the chance for a dungeon Event to occur in Cellars.
Cellars will now consistently reward a chest upon completion.
Fixed an issue where Cellars would prematurely be marked as complete.
Fixed an issue where the guaranteed elite monster would be absent from a Cellar.

General Quality of Life

Fixed an issue where players could increase attack speed by move-cancelling attacks early.
Fixed an issue where characters weren’t immune and untargetable after loading into an area.
The Reset Dungeon button has been disabled.
Fixed an issue that caused Gale Valley and Serac Rapture to have less monsters than intended until the campaign quests in those territories were completed.
