Diablo 4 players should avoid doing this until Season 11 begins

Diablo 4Season 11, dubbed the Season of Divine Intervention, is coming in just a few days and brings much-needed changes to the game loop, the various in-game activities, equipment upgrades, and the type of loot players can get. Since most of the changes coming with Season of Divine Intervention are permanent and affect gameplay beyond the newly created Season 11 characters, Diablo 4 players need to be careful what they do before the update goes live, and what is best saved for later.

Season 11 of Diablo 4 begins on Thursday, December 11, 2025 at 8:30 p.m. PDT. This is also the end time for Season 10, Season of Infernal Chaos.

While most players will make a new character when Diablo 4Season 11 begins, as this is the only way to experience seasonal gimmicks and content as they are introduced, many others will linger in the Eternal Realm to complete test builds, max out characters made in Season 10, or simply wait until 2026 when all of S11's content rolls out. If playing in Eternal is something you want to do, even in a small way, when Season 11 launches, you should not use any Resplendent Sparks to craft Mythic Uniques until the new update goes live.

Diablo 4 Season 11 Revealed, and It's a Game Changer

Diablo 4 Season 11 is coming on December 11th, with new seasonal challenges and permanent gameplay changes that will shake up the game in a big way.

How to get radiant sparks in Diablo 4, what changes in season 11

To bring in Resplendent Sparks Diablo 4players must normally beat Uber Lilith for the first time in the season or complete the season's reputation. Then you can save a Mythic Unique to get a Shiny Spark, which can then be used to create more Mythic Uniques.

Diablo 4s best Resplendent Spark farm was introduced in Season 10. This goes as follows:

Farm Infernal Warp on your main character.
Talk to Shyan to buy Warp Scrolls.
Transfer at least 89 Warp Scrolls to your inventory.
Create a new character of the same class as your protagonist.
Complete the Sands of Chaos seasonal quests to unlock the S10 reputation board.
Collect the 89 Warp Scrolls from your inventory and use them, gain 22,500 reputation and reach max rank.
Collect all cache rewards from the seasonal rumor track.
Close all caches and log in to your main character again.
Use the caches to get loot and a guaranteed brilliant spark.

Since Resplendent Sparks are preserved on seasonal characters when they transfer to the Eternal Realm, you can keep them all to create more mythic uniques. However, using Resplendent Sparks to create myths before Season 11 is released will immediately make those items Legacy gear when the update goes live, meaning they can no longer be upgraded.

Diablo 4's Tempering, Masterworking and Affixes in Season 11 explained

Upgrading Mythics in Diablo 4 is a huge part of the game, and using Resplendent Sparks to get yourself good items to use in Eternal to test builds, create new characters, or finish your current one can be counterproductive. This is because, outside of seasonal mechanics like Sanctification, the game is undergoing massive changes to its upgrade system. These are:

Hardens objects Diablo 4Season 11 has you choose from the list of possible affixes for the one you want, but the range on the scroll is still random. Tempering is also limited to once per item.
All items will have 4 affixes, as opposed to 2 or 3 previously.
Items can be processed to increase their quality, which will:
- Increase armor on all armor pieces.
- Increase the resistance of all jewelry.
- Increase the damage of all weapons.
- Increase all attachments by 1% for each quality level (cap of 20).
A complete masterpiece in Diablo 4 may gain a capstone bonus, which improves a random affix or Greater Affix by 50% (can be rerolled).
Sanctification, which is exclusive to season 11 after completing the season quest and permanently locks an item from future changes, but gives it a random property.

Why you should wait to create mythic uniques in Diablo 4

All of these changes, with the exception of the Sanctification option, will take effect when Season 11 is released. This means that Eternal items will be marked as “legacy”, as they will have two Tempering rolls and fewer affixes. As such, you should save your Resplendent Sparks to craft Mythic Uniques in Diablo 4 after the new patch is released; Otherwise, these items will also be classified as older. In addition, the new Masterworking system has i Diablo 4 can make most items better than they could have been before, so it's worth waiting for.
