Diablo 4 has always centered around acquiring exceptional loot, and with the introduction of Season 11, the game takes a significant step forward. The new feature, Hadriel’s Heavenly Forge, allows players to enhance their top-tier gear through a process called Sanctification. The High Heavens, led by the angels, are making a return to assist players, and although their contributions are limited, even minor enhancements to your best-in-slot (BiS) equipment can yield substantial benefits.
Utilizing Hadriel’s Forge to augment your gear may seem straightforward, yet it can be slightly perplexing initially. This guide will walk you through the Sanctification process in Diablo 4, while also addressing important aspects related to this enhancement system, such as limitations and the prerequisites for Sanctification.
How to Access the Heavenly Forge in Diablo 4

To reach the Heavenly Forge, simply use the angelic portal located in any of the main cities within the game. Once you arrive, you’ll meet Hadriel and several craftsmen gathered around the forge.
Upon interacting with the Heavenly Forge, you might experience a delay due to network lag, or a Sanctification menu could appear. Here, you can insert an item into the designated slot for Sanctification. However, before finalizing your selection, you’ll need to acquire a Heavenly Sigil.
Sanctification can yield the following enhancements for your gear:
- A random affix is upgraded to a Greater Affix.
- The overall quality of the item is elevated to its maximum potential.
- The impact of any gem set in the item is significantly amplified.
- The item can gain an entirely new and often potent affix.
It is essential to note one crucial limitation regarding Sanctification: once an item has been Sanctified in Diablo 4, it cannot be modified further. This means that alterations such as Tempering, Masterworking, changing Legendary Aspects, or adding sockets will no longer be possible. Ensure that you have no further changes in mind for the item before proceeding with the upgrade.
Where to Obtain Heavenly Sigils in Diablo 4

Heavenly Sigils can be obtained from various sources, including:
- Defeating World Bosses
- Taking on Bartuc from the Infernal Hordes
- Opening caches in the Dark Citadel
- Completing runs in the Kurast Undercity
- Collecting rewards from Helltide Tortured Gifts
- Exploring the Pit of the Artificer
- Finding Resplendent Chests
Moreover, on occasion, a portal to the Heavenly Forge may open upon completing activities like Nightmare Dungeons or Helltide boss encounters. This grants you a unique opportunity for a complimentary usage of Sanctification. Be mindful that this offer is time-sensitive, and neglecting the portal will forfeit your chance for a free upgrade.
