Diablo 4 will receive a new season update on December 11, 2025, at 8:30 PM (UTC). The season is called Season of Divine Intervention. This is expected to be the largest update for Diablo 4 to date, bringing a wealth of new content.
Season 11 will see the return of Lesser Evils. Azmodan, one of Lesser Evils of Hell, will become the game's first new World Boss. The item system will also be completely revamped. A new Toughness stat improves the defense mechanics, and the more challenging Seasonal Rank system replaces Seasonal Renown.

Enemies and monsters have been updated, and due to the changes to items and various mechanics, the different character classes will be significantly reshuffled.
The enemies and monsters in the game have been updated, and due to the changes to items and various mechanics, the different character classes in the game will also be reshuffled. This update includes a lot of content, so I will summarize the important updates for you. The following is the main content of this 2.5.0 patch update.
Item Upgrade Paths
In Season of Divine Intervention, item upgrade paths have changed, and the enhancement system has been redesigned.
Tempering
Players no longer randomly obtain Affix from the required Temper Manual; instead, they can choose any Temper Affix they have acquired and add it to their items. This eliminates the previous randomness and makes enhancement more targeted.
The item Tempering Charges have also been changed, as follows:
- Rare: 1 Temper
- Legendary and above: 3 Tempers, plus one per Greater Affix.
Note that Scrolls of Restoration have also been redesigned; they now only restore one temper charge, but there is no limit to the number of times they can be used.
The materials required for Tempering have also been updated:
- Rare: 25 Common Salvage and 5 Veiled Crystals
- Legendary: 15 Veiled Crystals and 5 Legendary Salvage
- Ancestral Legendary: 25 Legendary Salvage and Forgotten Souls
Masterworking
Masterworking has been redesigned. A new attribute, Refinement, has been added to items. Each time a player Masterworks an item, its refinement value randomly increases by 1-3%. The maximum refinement threshold is 20%. Once this threshold is reached, the item is considered Masterworked.
Items can now be Masterworked without tempering. The item quality cap has been increased from 20 to 25. Each Masterwork increases the quality level by 1-3 levels.
Each quality level increases the item's affix stats by 1%, resulting in a 50% increase in random affix stats after full enhancement.
When an item reaches its highest quality, you gain a final affix upgrade opportunity, allowing you to upgrade a random affix to a higher-level one. You can re-upgrade this Masterworked affix using Obducite and Neathiron without resetting the quality.
Neathiron can be obtained in Sanctuary, while Infernal Horde is the best place to farm Obducite.
Sanctification
This season update introduces a new item upgrade stage-Sanctification. It infuses items with angelic power, granting them the following abilities:
- Add an additional Legendary ability;
- Upgrade an Affix to a Greater Affix;
- Add an additional Affix to a set of special Sanctification Affixes;
- Replace an existing Affix with a random Sanctification Affix;
- Make the item extremely tough, preventing it from losing durability.
Sanctification renders your item unchangeable, it is the final upgrade.
Defense Mechanism Changes
Toughness
This update introduces a new defense concept called Toughness, a new attribute in Attack Power that represents how much raw damage you can withstand after all damage reduction measures are in effect. Details are as follows:
- When comparing items, Armor or Resistance difference between items will be displayed as a uniform percentage of Toughness difference, instead of just a fixed Armor difference;
- Toughness will be displayed in Character Stats window;
- Toughness tooltip will differentiate Damage Resistance by damage type;
- Torment difficulty will display a recommended Toughness value when the player selects a difficulty level.
Armor & Resistances
Armor and Resistance will both be part of a rating system. Higher ratings result in decreasing benefits, and Armor now reduces all types of damage, both physical and non-physical.
Below Torment Tiers, the previous penalties for Armor and Resistance have been removed. Damage reduction effects from Skills and Paragon Nodes will now be multiplicatively added to Armor and Resistance.
Healing Potion
Potions offer the best healing in the game, but their acquisition is limited. All players start with only 4 potions. However, players can obtain Renown by exploring map areas and completing various quests. Reaching certain Renown levels will then unlock Potion replenishment.
This update includes significant changes to Healing Potion:
- Potion now instantly restores 35% of maximum Life and no longer provides continuous healing;
- Potion regeneration time is now 30 seconds per potion, down from 12 seconds previously;
- Healing Affixes have been changed; they can now be found on leg armor as Potion Count Affixes;
- Since healing is now percentage-based, Potion level upgrades have been removed.
Fortify
Fortify effect has been reworked. To align with Healing Potion changes, Fortify will now consume additional Life storage instead of Damage Reduction to heal the player.
While a player has Fortify, they will remain in Fortified state, and Fortify stacks will add to the player's Maximum Life. Fortify-related skills, passives, and items have also been updated accordingly.
Enemy And Monster Difficulty Updates
Elites
To accommodate the newly added Champion and Rare Elites, the elite density in Dungeon and Overworld has been adjusted. Undercity Afflicted Monsters have also adopted a new rarity system, reducing the locations where players can gain extra time and increasing the game's challenge.
Meanwhile, the developers have integrated Lesser Evils into the endgame system during Season of Divine Intervention, with these demons joining different events.
Azmodan
Azmodan will be a permanent World Boss during the season and a key dungeon. Players must defeat him in Season Rank V Capstone Dungeon to progress.
Azmodan's resilience has been increased, making it more balanced with other World Bosses, and Shrines will no longer disappear during combat. Defeating Azmodan will reward players with a chest in the summoning area, which can be opened with Corrupted Essence.
Duriel
Duriel will replace Blood Maiden as the main summoned monster in Helltide. Pangs of Duriel will appear instead of Hellborne at the highest threat level, after which you can summon Duriel using Baneful Hearts.
Belial
It will appear in Pit as Lord of Lies. Belial Eyes will randomly appear in limited-time dungeons. Defeating them will stun nearby enemies but also summon a group of Belial Apparitions.
When you destroy enough eyes, Belial will appear. Defeating Belial is a worthwhile challenge; if you encounter it in a dungeon, don't let it go. Defeating Belial will grant additional rewards and an extra Glyph upgrade.
Andariel
Andariel may appear in the limited-time dungeon mode of Kurast Undercity. It corrupts Spirit Beacon, making it quite dangerous but also granting players more Attunement.
Beware of Shades of Andariel and enemies that may appear at any time in the dungeon. If Andariel himself appears as the final boss of Undercity, try to defeat him for even greater rewards.
Divine Gifts And Essences
This season's progression will revolve around Divine Gifts bestowed by the angel Hadriel.
Divine Gifts
Each gift contains the following rewards:
- A Reward (Base Buff)
- A Corrupted Gift (Increased difficulty but same reward)
- A Purified Gift (No negative effects, additional buff and double reward)
Players can socket gifts into special inventory panels. A Corrupted Gift in an outer slot increases the challenge before the reward is granted, while a Purified Gift in an inner slot removes the challenge and doubles the reward.
Essences
Players will receive a Corrupted Essence upon their first kill of each Lesser Evil in the game. Giving these Essences to Hadriel for purification will grant Divine Gifts. The specific Essences are as follows:
- Essence of Pain (Duriel): Socketables in Pangs of Duriel
- Essence of Lies (Belial): Additional upgrade chances in Pit
- Essence of Sin (Azmodan): Activity Keys and more Dungeon Keys
- Essence of Anguish (Andariel): Obols and movement speed bonus
Season Rank System
Season Journey + Seasonal Renown is about to be upgraded to a more challenging and rewarding Season Rank system. Players will need to complete a Capstone Dungeon to advance to the next rank. Renown is currently only effective in Eternal Realms.
The good news is that the difficulty of Capstone Dungeons is fixed and will not increase with rank. Renown is currently only effective in Eternal Realms.
Class-Unique Item Updates
Season 11 also introduces several new class Diablo 4 items, including:
- Chainscourged Mail (Barbarian Pants): Disables damaging Brawling Skills and greatly increases attack power;
- Khamsin Steppewalkers (Druid Boots): Damaging 100-150 enemies with Nature Magic Skills grants maximum movement speed, and enemies you charge at are immobilized for one second;
- Death's Pavane (Rogue Pants): Dance of Knives drops daggers upon hitting enemies; picking them up grants 1 Charge and significantly increases damage;
- Gravebloom (Necromancer Mace): Summons three smaller Golems with faster attack and respawn rates;
- Orsivane (Sorcerer Mace): Provides increased damage and a free Enchantment effect to unused Defensive Skills in the skill bar;
- Path of the Emissary (Spiritborn Boots): Core Skills are automatically triggered when the player moves.
In addition, Necromancers' shields have gained an offensive attribute, unlocking new tanky offense builds. Many players predict that Necromancers will become one of the hottest classes in the new season.
Besides these major updates, Season 11 also addresses many player feedback issues, fixing numerous gameplay problems and other bugs. Stay tuned for the upcoming Diablo 4 Season of Divine Intervention!
