Synthesised Stability is a new Atlas Keystone Passive Skill introduced in the 3.28 Mirage league. It is designed to facilitate "boss rushing" and repeat-farming of specific areas by changing how Atlas progression interacts with the new "Shaped Regions" system.

Synthesised Stability Atlas Keystone

PoE 3.28: Added a new Atlas Keystone Synthesised Stability, which grants Completing a Map Objective within a Shaped Region instead collapses a different Map within the Shaped Region.

Buy default, when you complete an objective in a Map within a Shaped region it collapses, removing itself from the Region. This causes all other maps in the region to gain additional modifiers. In cases where the shaped region would become bisected, only the region with the most connected maps will remain.

The new Shaped Region system is one that promotes running many different Maps, but for players that want to engage with this new system while still wanting to run the same map over and over again, the Synthesised Stability Keystone on the Atlas Tree enables exactly that.

Primary Use

It allows you to run the same influenced Map repeatedly. Normally, completing a map influenced by an Astrolabe (which creates a Shaped Region) removes that influence from the map you just finished. With this keystone, the influence is instead removed (collapsed) from a different map in that region, keeping your preferred map "juiced" and available for another run.

Strategic Goal

This is intended for players who want to farm a single efficient map layout over and over within a quadrant of the Atlas, rather than clearing through a variety of different map types.

Related

• Shaped Regions: Created by using a new item called an Astrolabe on the Atlas. This manifests a region where maps gain increasingly difficult and rewarding modifiers as you "cleanse" (complete) them.
• Memory Vaults: Successfully clearing all influenced maps in a quadrant allows you to speak to Eagon to access a Memory Vault for high-value rewards.
• Map Drops: Maps are no longer tied to specific areas on the Atlas, only to difficulty tiers, making it easier to sustain specific tiers regardless of where you farm.
