Here’s a complete walkthrough for the Lightless Arbor dungeon in Last Epoch.
Enter the Rift, wipe the area, and you’ll reach the Temporal Sanctum dungeon.
Be sure to have a Temporal Sanctum Key ready to start the dungeon.
You only need one key to jump into the dungeon, even if you’re playing with a group.
once you nail a key, head to the Temporal Sanctum entrance and interact with the gate.
Dungeon keys are one-time use.
There arefour difficulty optionsto select, labeled in-game as Tiers.
The higher the Tier, the more rewards you’ll receive.
If you don’t have either item, you won’t be able to create a Legendary.
after you grab a Unique that’s ready to become a Legendary, star the dungeon.
You must alternate between both timelines to find a path through the dungeon.
This dungeon requires you to travel between multiple timelines to reach the exit.
When you first enter the decrepit chamber, the entrance will be blocked by Void debris and black gunk.
You mustteleport to the Divine timelineto find a path forward.
Progress through the dungeon until you hit another dead-end, then swap timelines to find a path forward.
Repeat this process as needed.
You’ll find the exit in the Ruined Era near the northern edge of the zone.
Beyond that, the fight itself is rather simple.
In the above example, we placed a Unique ring with one Legendary Potential (1LP).
We insert an Exalted ring since it matches our item’s slot throw in.
Outside of Weaver’s Web items, this is the only way to craft Legendary items in Last Epoch.
