PoE Atlas Arcane Astrolabes List 3.28

Arcane Astrolabes are new currency items introduced in the Path of Exile: Mirage league (3.28) that allow players to apply powerful modifiers to a "Shaped Region" on the Atlas, covering multiple maps. These items increase map difficulty and rewards, creating highly juiced, unique, or league-mechanic-driven content in specific, clustered areas.

List of Atlas Arcane Astrolabes

Using an Astrolabe on a map on the Atlas creates a Shaped Region, affecting a quadrant or collection of maps within it.

• Regional Buffs: These regions grant increased rewards and specific league mechanics to all maps within them.
• Scaling Difficulty: Completing maps within a Shaped Region further increases the difficulty and rewards of the remaining maps in that region.

With these new Astrolabes, Eagon is able to trace her movement, but using them causes dangerous side effects.

When you use an Astrolabe on a Map on the Atlas, a Shaped Region will manifest itself in that quadrant, affecting many of the Maps within it. There are many different kinds of Astrolabes and they apply different types of Shaped Regions. For example, an Abyssal Region, which causes all the maps to have an additional Abyss. Or a Blighted Region, which adds a Blight Encounter.

How to use it

Speak to Eagon in your Hideout to right click this item and then left click a Map on your Atlas to apply a Shaped Region.

Adds a Shaped Region:

Memory Vaults

Fully clearing a Shaped Region grants access to a Memory Vault, which contains high-value loot specific to that Atlas quadrant.

Rewards and Difficulty

Completing maps within these Shaped Regions further increases the rewards—and difficulty—of other maps in the affected region, encouraging strategic, targeted farming.
