All Forgotten Altar (Lost Power) Locations in Diablo 4

A thrilling new power surge is electrifying Diablo 4, echoing familiar magical themes from beloved fantasy series like Harry Potter and Agatha All Along. Embarking on this coven journey and mastering its intricacies, however, isn't a walk in the park. To aid you, here's a comprehensive guide to all Forgotten Altar locations in Diablo 4.

How To Find All the Forgotten Altar Locations in Diablo 4

The Season of the Witchcraft introduces a captivating questline unlocking potent Witchcraft Powers. These powers are categorized into three distinct schools: Eldritch, Psyche, and Growth & Decay, each specializing in a unique form of occult magic. To harness these abilities, you must cultivate favor with The Coven, achieved by diligently completing their assigned missions and earning Restless Rot.

Significant progress unlocks the ability to upgrade structures near the Tree of Whispers, known as Altars. While many players focus on the primary Altars, a more elusive type offers a different magical path. Forgotten Altars bestow Lost Powers—exceptionally potent abilities. However, locating these hidden sanctuaries is far from straightforward.

Unlike their predictable counterparts, Forgotten Altars don't have fixed spawn points. Instead, they randomly appear within Sanctuary's dungeons. This necessitates some exploration, but the season's questline often leads you through dungeons, potentially minimizing extra effort. Regardless, the potent Lost Powers make the search worthwhile.
