Uncover the Secrets of Diablo 4's Forgotten Altars and Lost Powers

The Season of the Maelstrom introduces Witchcraft Powers in Diablo 4, reminiscent of magic systems in series like Harry Potter and The Witcher. Mastering these powers requires dedication, and a key element is discovering the elusive Forgotten Altars. This guide details their location and the potent Lost Powers they unlock.

Unlocking Witchcraft's Potential

The Witchcraft system features three core categories: Eldritch, Psyche, and Growth & Decay, each representing a distinct magical discipline. To gain access, you must earn favor with The Coven by completing specific tasks and gathering Restless Rot. This progress allows you to upgrade Altars near the Tree of Whispers. However, the Forgotten Altars offer a unique path to power.

The Challenge of Forgotten Altars

Unlike the standard Altars with fixed locations, Forgotten Altars appear randomly within Sanctuary's dungeons. This requires exploration and some degree of grinding, but the rewards are substantial. The Lost Powers they grant are among the game's most powerful abilities, making the search worthwhile. Since the seasonal questline already involves dungeon exploration, you may stumble upon them naturally.
