Stellaris 3.10.0 Pyxis Update and Astral Planes Expansion Patch Notes
Stellaris version 3.10.0 Pyxis overhauls the leader system with class consolidations and new UI features alongside the Astral Planes expansion. Explore dozens of new branching rifts, mechanics, and balance adjustments.
The Stellaris 3.10.0 Pyxis update arrives alongside the Astral Planes Narrative Expansion. This patch reorganizes the entire leader system, introduces tabbed outliners, adds new planetary decisions, and rebalances empire civics, traits, and traditions.
Leader System Overhaul and Class Consolidation
Admirals and Generals merge into the Commander class. Governors and select Envoys merge into the Administrative Official class, which represents your empire in the Galactic Community and Federations. Scientists remain the third leader class. All three classes can now govern planets and sectors to apply specific military, administrative, or scientific bonuses. Leader capacity rules change significantly, removing generic capacity while supporting three leaders per class without penalties. Administrative Leaders can no longer serve as Head of Research, and mandatory council positions like the Minister of Defense and Head of Research are now optional, though vacancies incur a 25% penalty to naval capacity, diplomatic weight, or research speed.
UI, Outliner, and Content Browsing
The interface receives a major organization pass with a new Tabbed Outliner dividing information into Government, Ships, Politics, and Structures tabs. The Recommended Content window is replaced by an Additional Content Browser that previews origins, civics with nested tooltips, portraits, and shipsets. Event windows now display event chain titles and subtitles for original precursors, and improve and harm relations monthly values now show two decimal places.
Exploration, Planets, and Balance Changes
Three new planet modifiers join the game: Abundant Geothermal Activity, Subterranean Wildlife, and Rich Microflora. Four new planetary decisions let players remove negative modifiers like Bleak Planet, Hazardous Weather, and Dangerous Wildlife without terraforming. Diplomatic stances now directly modify external leader pool sizes, and council legitimacy directly scales base agenda speed from 50% at zero legitimacy up to 125% at max legitimacy.
Astral Planes Expansion Features
Players who purchase the Astral Planes Narrative Expansion gain access to over 30 Astral Rift sites featuring branching narratives and multiple endings. The expansion introduces the Astral Thread resource, Rift Sphere technologies, Astral Scars, eight new relics, ten baseline astral actions, four additional actions for Overlord owners, the Riftworld Origin, four new civics, three music tracks, and dozens of new event pictures and sound effects.
Why this patch matters
The Pyxis update restructures Stellaris management layers, demanding a fresh look at council layouts, leader deployment, and empire scaling.
