The Temporal Sanctum dungeon is the heart of Legendary item crafting. Before entering, a Temporal Sanctum Key is required. Once inside, the dungeon introduces a unique mechanic: timeline swapping. Pressing the D key switches the dungeon between two versions of Last Epoch gold the map, often revealing new paths or bypassing hazards.

Dungeon Layout and Progression

The Temporal Sanctum consists of multiple floors. While layouts can vary, paths tend to lead upward or north, making those the best initial directions when navigating.

Throughout the dungeon:

Certain doors or terrain may be blocked in one timeline but passable in the other.

Progress often requires swapping back and forth to reveal objectives, interact with devices, or open new routing options.

This pattern continues until reaching the final floor, where the boss-Jura-awaits.

Defeating Jura Using Timelines

Jura is designed around timeline swapping. The fight becomes more complex as dungeon tiers increase, but the fundamentals always apply.

Jura's most dangerous attacks include:

A large, circular clock-shaped hazard is placed on the ground.

Rotating beams that sweep across the arena.

Both threats can be avoided by shifting timelines. These hazards disappear when switching timelines, allowing safe repositioning. Players may either remain in a safe timeline until the effects expire or wait for Jura to shift between timelines and re-engage.

Upon defeating Jura, a passage opens leading to the chamber where Legendary forging takes place.

Forging a Legendary Item

The chamber contains the player's stash and a special cache. Depending on the timeline, the cache will either:

Present the final Legendary item for pickup, or

Display the interface where the unique and exalted items are placed for merging.

If the wrong version appears, simply swap timelines.

To merge the items:

Place the unique with Legendary Potential in the left slot.

Place the exalted item with four affixes in the right slot.

The number of affixes transferred to the unique equals the amount of Legendary Potential on the unique item. These affixes are selected randomly from the exalted item's pool. After confirming, swap timelines again to retrieve the completed Legendary from the alternate version of the cache.

Successfully merging items yields a powerful Legendary equipped with unique effects plus high-value affixes, making it one of the strongest gear pieces obtainable for any build.

Understanding Weaver's Will

Weaver's Will is often encountered alongside Legendary Potential, but functions entirely differently. Instead of merging with an exalted item, a Weaver's Will item evolves independently through combat.

Each Weaver's Will item begins with a special counter. When worn, the item gains experience as enemies are killed. At certain thresholds, it will:

Add a completely new affix, or

Upgrade an existing affix on the item.

These added affixes can be exceptionally strong-or completely irrelevant-depending on the build being used. Fortunately, Weaver's Will items drop commonly at cheap Last Epoch gold higher levels, allowing experimentation with multiple versions until desirable outcomes are obtained.
