Blizzard previously did not do PTR tests in the update of "Diablo 4" and updated the game directly without giving patch instructions, and after being sprayed by players, it began to announce the patch instructions about a week in advance. In the early hours of December 2nd, Blizzard updated Diablo IV with 12.3 Patch Notes, which will be available on December 6th, includes the previously promised enchantment preview modifiers, and Zil's Slaughterhouse is expected to be implemented with the patch. 
The full list of possible modifiers can now be viewed in the enchantment menu using the new View Possible Modifiers button. Increased the amount of glyph experience gained from most Nightmare Dungeon levels. Levels 1-17: No change. Class 30: from 66 to 79. Class 50: From 106 to 139. Class 75: From 156 to 239. Class 100: From 206 to 339. Dev Note: After looking at the game stats and player feedback, we realized that completing the higher Nightmare tiers didn't pay off as much as we had hoped, with many players stopping their adventures after reaching level 50. The purpose of increasing the Glysed XP at the higher tiers is to motivate players to progress through their respective genres and give them a greater sense of accomplishment when they reach tier 100. We will closely monitor changes in the player experience and encourage players to provide any feedback we have about the system.
Added support for NVIDIA Reflex technology. Please enable this feature in the in-game settings. Bug fixesAccessibility toolsFixed an issue where screen reading aloud didn't have the blood pact required to read the Vampire ability. Fixed an issue that caused the screen to be read aloud on Steam Deck. DungeonsFixed an issue where trap boxes would not respawn if the player was killed by a boss in a fortress of faith. Fixed an issue in the Dungeon where if the Idol of the Temple of Destruction was destroyed instantly, the goal of destroying the Idol would not be completed correctly. Fixed an issue where exiting and re-entering the Dungeon of the Sinked Demon would avoid its negative effects. Fixed an issue where enemies could spawn behind locked doors in the Holy Orifice during the Sole Survivor event, preventing the Mastery event from being completed. Fixed an issue where playing local co-op would not properly reset the Nightmare Dungeon after all respawns were exhausted. Fixed an issue where monsters with summoner modifiers and carrying Hate would unexpectedly spawn enemies with Hate. Fixed an issue where the Nightmare Dungeon's extra elemental damage modifiers would be too low or too high for each tier. GameplayFixed an issue where dying while Lilith's Echo battle was starting would cause certain attacks to not trigger correctly. Fixed an issue where the first time Lilith's Echo cast Death from the Sky would have an irregular timing and the incoming projectile attack indicator would not display correctly. Fixed an issue where Frostburn and the Embracement of the Virgin could drop Hallowed items instead of Ancient in Echo of Vason's Agony in World Class IV Fixed an issue where certain gem fragment acquisitions, such as Greedy Chests or Whispering Chests, would still drop gems instead of gem fragments. Fixed an issue where a companion werewolf from the Boss's Legendary Essence could miss when casting Rabid Bite Fixed an issue where druids could keep hitting walls if they used trample to move to nearby walls. Fixed an issue where if the player rode or dismounted near a Treasure Hoarder, the Treasure Hoist would sometimes become invincible and run away. (Wanderer, the Treasure Heist Goblin has had enough of your bullying.) ）Season of BloodFixed an issue where Blood Reapers, which could despawn quickly after spawning. Fixed an issue where Novik enemies could respawn repeatedly under certain co-op situations. Fixed an issue where the Hate Seeds extracted would not count towards the progress of the Seasonal Journey Objectives after becoming the Hate Chosen Disciple. Fixed an issue where powerful blood that caused Blood Wells to fall could not be obtained. Dev Note: A previous quick fix allowed players to traverse blood wells and gain powerful blood. This change reverts to the ability to travel through blood wells, but Powerful Blood no longer spawns in the middle of blood wells, making it easy to pick up.
Fixed an issue where Durrell would not spawn when the player respawned and re-entered the boss arena. User Interface and User ExperienceFixed an issue where the maps of Hell Wave and Bloody Harvest overlapped and did not display correctly when entering an area covered in the fog of war. Fixed an issue where tooltips could flash periodically when the cursor was moved over certain items. Fixed an issue where the description of unlocking mounts would be inaccurate for players who skipped story missions. Dev Note: If you choose to play Story Missions, players who have not yet unlocked their mounts will have to complete the Donan's Favor quest to unlock them. If you skip the story mission, you must reach level 25 before you can unlock the mount. The previous hint only mentions the quest to be completed, but not how to unlock it when skipping the story quest.
Fixed an issue where entering the Season Journey from Seasonal Highlights would prevent the correct Chapter from being opened. Navigating Seasonal Chests with a controller is now more consistent. MiscellaneousFixed an issue where the visual effects on armor would still be fully visible when hidden. (Stupid wanderer, Lilith has seen through it.) Various visual, performance, and stability improvements.
