Diablo 4’s next big system is literally going to bring some divine power to Sanctuary. After changing completely how crafting and item progression works with all the Tempering and Masterworking rework, Blizzard is adding a final touch for endgame crafting, and that is Sanctification.
This new system will sort of channel the “power of the High Heavens” into your gear. This lets you ascend your best items to a new, celestial level.
What Is Sanctification
When you Sanctify an item, you will essentially bless it with some sort of angelic energy. However, it is not just another way to boost your stats. Each Sanctified item gets unique effects that can completely change its potential:
- Gain a bonus Legendary power
- Upgrade an affix into a Greater Affix
- Add a bonus Sanctification affix from a special set of affixes
- Replace an existing affix with a random Sanctified one
- And even make the item indestructible
However, once you have Sanctified an item, its journey ends there. This means that you can not modify it anymore. It is meant to be the final, ultimate upgrade to your weapon or armor.
So you will have to first make sure you perfect it with Tempering, Masterworking, Enchanting, before you use the Sanctification system.
How to Sanctify Items

There are two ways to access this angelic upgrade:
- In Pre-Torment difficulties, you can earn a divine invitation after defeating a Lesser Evil in activities like Helltide. This grants a rare chance to Sanctify an item at the Heavenly Anvil, but if you skip it, you will have to wait for another invitation.
- In Torment difficulties, you will need Heavenly Sigils. Those let you access the Heavenly Forge to Sanctify Ancestral-quality items whenever you want.
Why Is Sanctification So Important
Sanctification feels like Blizzard’s way of giving players a true “final destination” for their best loot. This is a way to lock in that perfect weapon or armor once all other upgrades are done. It is cool, powerful, and fits perfectly with the angelic theme of the upcoming Season.
Between Tempering, Masterworking, and now Sanctification, Diablo 4’s entire gear progression is looking far more refined and satisfying, and that is something long-time players have been asking for since launch.
