As you progress through each season in Diablo 4, you will need stronger equipment to take on tougher challenges and more demanding content.
One of the ways to improve your gear is through Tempering, a system introduced during the Season of Loot Reborn that expanded how equipment can be customized.
Tempering allows you to add an additional affix to your equipment, providing new stats that help strengthen your build and improve overall combat performance.
How Does Tempering Work?
Tempering is a feature available through Blacksmiths, allowing you to add an additional affix to eligible items regardless of which town you visit.
You obtain Tempering Recipes by using Tempering Manuals, which drop as loot from defeating enemies, opening reward chests, clearing events, and fighting bosses.
Tempering Manuals come in different rarities and stat ranges, and finding a higher-quality manual will replace older versions with weaker affix options.
Once a recipe is unlocked, it appears in the Tempering menu, letting you select related affixes when modifying your gear.
Tempering can be applied to Rare-quality items or higher, and you may reroll the temper to improve the affix value or change it to a different option.
Tempering Affixes Count
When Tempering your equipment, you are allowed to add two Affixes to your Ancestral Legendary Equipment, making it possible to boost your build even further.
This is limited to adding one Recipe Category per equipment, where an example would be having one Affix from the weapons category and another Affix from the Offensive Category.
With this feature, you can add 2 Affixes to all of your Ancestral Legendary Gear provided you have enough resources for the Tempering process.
How To Use Tempering?
Tempering is available from the moment you log in with your character and may be used by visiting any Blacksmith you can find.
Once you select Tempering, place the item you wish to add an affix to, and you can select a recipe that will add an affix from a list of possible options.
You may also select a recipe first, which will show you which equipment may be used to get one of the possible affixes from it.
After choosing the equipment and recipe that you want, you may confirm by selecting “Temper Item” and this will complete the process, giving the equipment a random affix.
Tempering is limited to a certain number of times though, which can be shown once an item has been placed in the slot, which shows the remaining amount of rerolls available.
Where To Get Temper Manuals?
Temper Manuals can be obtained through normal gameplay by defeating enemies encountered throughout Sanctuary.
Stronger enemies such as elites, bosses, and event encounters have a higher chance to drop Temper Manuals, making them more reliable sources overall.
Participating in activities that reward chests is also effective, as these chests can contain Temper Manuals alongside other valuable loot.
Helltide zones are among the best places to farm Temper Manuals, thanks to the high enemy density, frequent events, Tortured Gift chests, and encounters like Blood Maidens.

How To Upgrade Tempering Recipes?
Tempering Recipes initially unlock with lower stat ranges, meaning the affixes you apply have more limited minimum and maximum values at first.
Obtaining duplicate Temper Manuals automatically upgrades the recipe, increasing the stat ranges the affix can roll.
Once a Tempering Recipe is fully upgraded, it allows the highest possible stat ranges for that affix, making upgraded recipes essential for endgame gear optimization.
Verdict
Tempering plays a key role in shaping effective builds, giving players a reliable way to enhance gear as difficulty increases throughout a season.
Upgrading recipes over time rewards continued play and preparation, making each improvement feel meaningful rather than dependent on luck.
When used consistently, Tempering helps bridge the gap between early progression and endgame content, ensuring smoother overall character growth.
