Most Stellaris build lists you will find were written before 4.5, and a good part of what they recommend has been nerfed, fixed or reworked by the ‘Cygnus’ patches since.

Right now, the strongest build is Knights of the Toxic God played as a nomadic empire. The best all-rounder is the Cybernetic Creed megacorp, which more or less plays itself once the economy is running. If you are new to the game and do not own any DLC, start with the beginner build further down, because it uses nothing outside the base game.

All the ethics, civic, trait and origin combinations below are legal in the 4.5.2 game files, and the picks follow what is actually strong in 4.5 games right now. Stellaris 4.6 ‘Corona Borealis’ and the Willpower expansion release on 23 November 2026, and I will update this page for them.

Several of the builds take the Statecraft and Aptitude traditions early, and both belong to Galactic Paragons. If you do not own it, take Prosperity or Discovery in their place and keep the rest of the plan as it is.

1. Knights of the Toxic God (nomadic)

Knights of the Toxic God has been a top pick since 4.3, and 4.5 made it better by letting you play it as Nomads. Your Knights are specialist jobs that make Unity, all three research types and naval capacity at once, and they also count as Soldiers for most soldier bonuses.

This version follows Montu’s “idiot proof” nomadic Knights video from the 4.5 beta. The setup below keeps his ethics, civics, traits and tradition order, but it ascends Cybernetic instead of Synthetic and plans around the 4.5 nerfs that came after the video.

• Ethics: Militarist, Egalitarian, Spiritualist
• Authority: Oligarchic
• Civics: Citizen Service and Exalted Priesthood, then Meritocracy as the third civic
• Origin: Knights of the Toxic God, as a nomadic empire
• Traits: Very Strong (3), Enduring (1), Solitary (-1), Jinxed (-1)
• Ascension: Cybernetic, through The Flesh is Weak
• DLC: Toxoids Species Pack and Nomads, with Galactic Paragons and The Machine Age as optional extras

Oligarchic is the only authority that allows both starting civics, because Citizen Service needs Democratic or Oligarchic and Exalted Priesthood needs Oligarchic or Dictatorial. Citizen Service gives +2 Unity per 100 Soldiers, counting your Knights and the Lord Commander, and adds +15% naval capacity.

Exalted Priesthood turns your Politicians into High Priests and adds +1 Unity per 100 Bureaucrat or Priest jobs. As Nomads you will keep your Politicians, since only the settled Knights habitat swaps them for Knights. My Stellaris civics tier list ranks them outside of this build.

Very Strong is the key trait, with +15% job efficiency for Soldiers, Knights and the Lord Commander and +40% army damage. Enduring adds 20 years of leader lifespan, and Solitary and Jinxed are cheap negatives that pay for it.

Send out an extra science ship early and replace the Holo-Theatre with an alloy foundry. Knights cost 1.15 alloys and 0.15 consumer goods per 100 before quest boons, and alloys are going to be your first bottleneck. Each Knight’s Quest boon that raises output will add +100% to your Knights’ base Unity or research, but also +15% to their upkeep.

Go Statecraft, then Prosperity, then Aptitude (my tradition tier list ranks the other trees). Your first perk is Voidborne once you have researched Arkship Engineering, and it gives nomads +2 max Arkship districts, cheaper Arkships and +20% Arkship habitability. Technological Ascendancy comes second and The Flesh is Weak third. Put Strongholds on the Knights Arkship, where they will give Knight jobs at half the Soldier count, and research Global Defense Grid, which unlocks the Fortress upgrade and doubles those jobs.

Make your leaders governor-commanders and aim for the Grand Taskmaster destiny trait, which makes each 100 Soldiers or Knights on the governed planet also produce 0.5 energy, minerals and food. It needs Galactic Paragons. Between years 20 and 30, switch to Utopian Abundance when your consumer goods allow it, take The Flesh is Weak and add Meritocracy, whose +10% specialist output your Knights will inherit. For the fight against the Toxic God, frigates or torpedo cruisers will do the job, and my fleet composition guide has more on designs.

The price of all this is upkeep, because Knights eat alloys and consumer goods. You also start with 1,100 fewer pops and cannot settle until the Knight’s Quest is done, although since 4.5.2 you may settle once you reach the Toxic God’s system and keep the Order’s Keep and your Knights.

Nomads cannot take Fortification or Sovereign Guardianship, and your Spiritualist pops are not going to love the cyber ascension. The Limited Cyberization policy makes their faction’s approval penalty smaller, but avoid it anyway, because under it your Cybernetic Spiritualist pops do not get the Cybernetic job efficiency.

If pops hold you back more than Unity does, take Deep Sleep instead of Exalted Priesthood for +3,000 starting pops and swap Spiritualist for Materialist.

Settled Knights without Nomads

There is no clear consensus pick for wide conquest in 4.5, and Knights are the conquest build I would go with. Without Nomads, play them settled with Fanatic Militarist and Egalitarian, an Oligarchic government, Citizen Service and Meritocracy, and Distinguished Admiralty (+10% fire rate, +20% command limit) as the third civic.

Open with Expansion and Fortification, which needs Apocalypse or Overlord, and take Imperial Prerogative, Voidborne and The Flesh is Weak as your perks. Voidborne then gives +2 max districts to the Knights’ starting habitat (more in my habitats guide). Grow through vassals and build an Order’s Commandery on each vassal’s capital once it has 5,000 pops. It adds naval capacity and 100 Overlord Knight jobs that make Unity and research for you, which matters because your conquered worlds will not get Knights. Skip Sovereign Guardianship here, since it adds +75% Empire Size from colonies.

2. Cybernetic Creed megacorp

• Ethics: Fanatic Spiritualist and Egalitarian (Xenophile also works instead of Egalitarian)
• Authority: Corporate
• Civics: Augmentation Bazaars and Sequenced Securities, then Dimensional Enterprise as the third civic
• Origin: Cybernetic Creed
• Traits: Traditional (1), Compliance Filters (1), Rapid Breeders (2), Sedentary (-1), Slow Learners (-1)
• Ascension: Cybernetic through the origin, with no ascension perk needed
• DLC: MegaCorp, The Machine Age, BioGenesis and Astral Planes, plus Galactic Paragons if you have it

This is the build I would hand to anyone who wants strong results without much micromanagement. Cybernetic Creed turns your priests into Haruspex, and in a megacorp each 100 Haruspex will make 2 Unity, 1 engineering research and 2 trade for 2 consumer goods. Sequenced Securities adds 1.5 society research to them and Dimensional Enterprise adds 1 physics. One job ends up covering all three research types plus Unity and trade, and you will simply build more of it.

Make sure to take Augmentation Bazaars at empire creation, because you cannot reform into it later. It lets you pick cyborg traits like Compliance Filters at creation, places an Augmentation Bazaar on your capital and speeds up the Conclave of Fusion situation. Traditional and Compliance Filters each give +10% job efficiency for Administrative jobs, and since the Haruspex is the Bureaucrat job under another name, both should apply (check the Haruspex tooltip to confirm).

• Queue Integrated Cybernetics on day 1. The Creed guarantees it as a research option.
• Open Commerce first and take Adaptive Economic Policies early. Its Consumer Benefits trade policy turns half your trade into consumer goods, which keeps 2 consumer goods per 100 Haruspex from crashing your economy.
• Adopt Cybernetics the moment Integrated Cybernetics is researched, and pick Extra Funds or People Powered in the Conclave of Fusion situation.
• Grow Haruspex jobs before you build research labs, and add Dimensional Enterprise after Galactic Administration.
• Spend influence on Branch Offices on rich neighbour planets. Since 4.5 each one costs 75 influence plus 5 per jump, and your trade policy converts their trade as well.

After Commerce and Cybernetics, take Statecraft if you own Galactic Paragons and Prosperity if you do not. Technological Ascendancy and One Vision are good first perks, since megacorps cannot take Imperial Prerogative, and my ascension perks guide ranks the rest.

The ascension is the strongest part of the build. Cybernetic Creed skips the ascension perk entirely, which means no waiting for two other perks first.

Once the Cybernetics tree is open, the Conclave of Fusion situation starts, and more Haruspex will make it run faster. With Augmentation Bazaars you also do not need an Augmentation Center for it to finish. When it completes, the Cybernetic trait gives your pops +10% job efficiency and +20% habitability.

The 4.5.3 open beta from 28 October 2026 fixes a bug that could leave Cyberization stuck at -99% speed after dealing with spiritualists.

The weak points are money and DLC. The full version needs four DLC, and consumer goods are going to stay the bottleneck all game. The Corporate authority adds +50% Empire Size from colonies and each Branch Office adds 5 Empire Size, which means you should expand at a moderate pace. Only one empire per galaxy can have Cybernetic Creed, and once you go Cybernetic, Psionic is off the table for good.

If you only own MegaCorp and The Machine Age, pair Augmentation Bazaars with Gospel of the Masses instead, which gives +1 trade per 100 Haruspex, and keep the same ethics, traits and plan. Your Haruspex will then only make engineering research, and you will need normal research jobs next to them.

3. Wilderness hive with Behemoth Fury

The Wilderness Behemoth build still works in 4.5.2. What changed is the speed. Since 4.5, killing, breeding or capturing fauna and bio-ships gives the Behemoth crisis only a fifth of its old progress, and the old trick of feeding it your own empty bio-ships is much weaker because of that. The Mind Meld payoff at the end was not touched, though, and for a Wilderness empire it is still enormous.

• Ethics: Gestalt Consciousness
• Authority: Hive Mind, which Wilderness turns into Mutualistic Intelligence
• Civics: Natural Neural Network and Divided Attention, then Elevational Contemplations (the game shows it as Elevational Desires) as the third civic
• Origin: Wilderness (needs a bio-ship shipset and a homeworld that is not volcanic)
• Traits: Aquatic (2), Agrarian (2), Quick Learners (1), Rooted (-3), with an Ocean homeworld for Aquatic and a Fungoid or Plantoid species for Rooted
• Ascension: Biomorphosis into Purity, then Behemoth Fury as the crisis perk
• DLC: BioGenesis and Aquatics Species Pack, plus Federations if you start with Empath and reform into Divided Attention around year 20

Mind Meld is the last Behemoth crisis level. It gives your capital Mindlink districts, and for a Wilderness empire each one pays 300 Unity and 100 of each research per 1% of transferred pops. Any other empire gets 1.5 Unity and 0.5 research from the same district, which makes the Wilderness version a 200x multiplier.

When Mind Meld starts, each colony above 500 pops will lose 0 to 4 pops at random, and each of those pops adds +100 to the transfer. As such, you want as many big colonies as possible before you trigger it.

Build a Cradle of Rebirth on day 1 and keep adding more, because Wilderness colonises by terraforming and builds with Biomass. Take Prosperity first, then Statecraft, Aptitude and Adaptability.

Biomorphosis needs two perks before it, so spend your first two on Hydrocentric and World Shaper to turn your worlds into oceans, or swap one of them for Mastery of Nature if you are short on districts. Biomorphosis comes third, and since 4.5 its situation takes about half as long. Purity is the only genetic tree Wilderness can take. Behemoth Fury comes fourth, since it needs three perks before it and bio-ships, and after that you will push the crisis to level 5 and take Mind Meld.

This is a wide build. Claim and conquer as many planets as you can, and you will find that Wilderness worlds run at full output soon after you take them. Elevational Contemplations makes colony ascension cheaper and stronger, and ascending your planets keeps Empire Size down, and Divided Attention stacks a second -25% Empire Size effect. For a more aggressive game, Devouring Swarm (the game shows it as Devouring Wilderness) with Natural Neural Network gives you the “Blood Forest” version.

The downside is time. The start is very slow, the setup is long, and Mind Meld needs a lot of conquered planets before it pays off. If you enjoy building toward one huge late-game payoff, there is probably no other build here with a bigger late game. If you want early strength, pick the Knights or the Creed instead.

4. Teachers of the Shroud psionic

Most psionic builds have to spend an ascension perk on Mind Over Matter before anything happens. This one does not. Teachers of the Shroud and the Chosen civic both count as psionic ascension, which means researching Psionic Theory alone opens the Psionics tree and the Psionic Ascension situation. The origin guarantees Psionic Theory as a research option, and your first perk is free for something else.

• Ethics: Fanatic Spiritualist and Authoritarian
• Authority: Imperial, or Dictatorial
• Civics: Chosen and Environmentalist, then Ascensionists as the third civic
• Origin: Teachers of the Shroud
• Traits: Uncanny Intuition (3), Intelligent (2), Natural Sociologists (1), Nonadaptive (-2), Unruly (-2)
• Ascension: Psionic, with the Composer of Strands as your patron
• DLC: Overlord and Shadows of the Shroud

Uncanny Intuition (+2 effective councilor skill) needs a Shroud psionic portrait. Without one, take Intelligent, Natural Sociologists, Traditional and Unruly.

Environmentalist is what makes the economy work. Its Ranger Lodge on the capital gives 100 Ranger jobs plus 100 more for each natural blocker on the planet, and +1 Unity per natural blocker, so a capital with five blockers runs 600 Rangers. Rangers are a Biologist job, which is why Natural Sociologists is in the trait list.

The patron you want is the Composer of Strands. Your Fanatic Spiritualist ethic, Environmentalist and the Chosen gift of +300 attunement all push you toward it.

Passive accords open at 30% and 60% attunement and the Covenant at 70%. Its Growth accord gives your main species +20% pop growth, and its aura adds +10, +20 or +30 Unity per natural blocker on your planets. Later on, Transformation turns an uninhabitable world into a size-10 Gaia world every 10 years for 50 Zro, and Expansion adds +100 pops to each colony inside your aura for 150 Zro. That covers pop growth, which is usually where psionic empires struggle.

On day 1, pick the Composer in the Chosen event and leave the natural blockers on your capital alone. Go Statecraft, then Prosperity, and adopt Psionics in your next free slot as soon as Psionic Theory lands. For perks, take Transcendent Learning first, then Technological Ascendancy, then Imperial Prerogative. Settle worlds with many natural blockers and put a Ranger Lodge on each. You can only have one per planet, it needs a free district, and it cannot go on Ecumenopolis, Relic or habitat worlds.

At 60% attunement, the Vigor accord unlocks the Shrouded Vegetation decision, which plants 2 more natural blockers for 1000 food. Under the Covenant those blockers cost no district and even add a Farming district, and each one will feed both your Ranger Lodge and the aura’s Unity. Build the Sanctum of the Composer for 300 Telepath jobs once your capital building is upgraded. Since 4.5.2, the Covenant’s Telepath bonuses apply as soon as you form it.

If the Divine Sovereign coronation fires later, accepting is optional. It resets your ethics to Fanatic Authoritarian and Spiritualist, makes you Imperial and adds the permanent Divine Sovereign civic with +10% Unity. Under Imperial rule the crowned leader must be your heir, and Dictatorial is the alternative if you want any Chosen leader to be crownable.

Of all the builds here, this one leans on luck the most, because your economy rides on how many natural blockers your capital and colonies roll.

Turning a planet into an Ecumenopolis destroys its Ranger Lodge. Chosen is permanent and, together with the origin, locks you out of the other ascension paths, and the Composer Covenant will cost you 2 species trait picks. Only one empire per galaxy can take Teachers of the Shroud. Mind that if the game hands you the corporeal Imperial government, Imperium Vitalis, your psionic pops lose 20% job efficiency.

The Instrument of Desire raises pop upkeep by 25% under its Covenant, and I would only take it for an entertainer build like the Forever Cruise one further down.

5. Rogue Servitor with Virtuality

Rogue Servitor has stayed a strong machine pick from 4.0 to 4.5. Your Bio-Trophies keep scaling, and the Virtual ascension stacks a lot of job efficiency on a small number of planets, which makes this a good fit if you like a compact empire.

• Ethics: Gestalt Consciousness
• Authority: Machine Intelligence
• Civics: Rogue Servitor and Astro-Mining Drones, then Rapid Replicator as the third civic
• Origin: Arc Welders, or Remnants for a relic world start
• Traits: Emotion Emulators (1), Logic Engines (2), Bulky (-1), High Maintenance (-1)
• Ascension: Synthetic Age into Virtuality
• DLC: The Machine Age and MegaCorp, plus Ancient Relics only for Remnants

Emotion Emulators is there because the Bio-Trophy counts as an Influential job and gets its +20%. Bulky looks like a poor trade at first, but Virtual’s -90% housing for machine pops will cancel it later. Astro-Mining Drones gives +50% mining station output but -50% Menial Drone output, which roughly breaks even, and if you plan to fight early, take Tactical Algorithms instead.

Get organic pops into Organic Sanctuaries as early as you can. Each 100 Bio-Trophies on a planet give +1% Complex Drone efficiency there, and that is the job your whole empire scales with. Be ready for early aggression as well. Traditions go Prosperity, Statecraft and Aptitude, then the Virtuality tree. Take Synthetic Age as your third ascension perk at the latest, since it needs two perks before it and a free tradition slot, and pick Virtuality in the Transformation situation.

Settle only a few good planets. Virtual’s Clustered Capacity gives +75% job efficiency minus 10% per colony, and you will feel each extra colony. After that, Arcology Project for an ecumenopolis capital is the natural next step. If you would rather take Modularity, it doubles Bio-Trophy Unity from 1 to 2 per 100.

Bio-Trophies need organics and consumer goods, with Mandatory Pampering costing +1 consumer goods per 100, and the Virtual penalty works against wide expansion. 4.5.2 also took away the free job automation that Fallen Empire buildings gave Virtual empires. In the 4.5.3 open beta from 28 October 2026, the Virtual Bliss Plaza and Omni-Bliss Nexus automate Logistic Drone jobs for gestalt empires.

6. Beginner build without DLC

This one does not have the highest ceiling, and that is fine. Each pick is a flat bonus that is always on, nothing has to be combined to work, and it needs no DLC at all. I call it the Prosperous Technocrats, and if you are new, I would play it before any of the builds above.

• Ethics: Fanatic Egalitarian and Materialist
• Authority: Democratic
• Civics: Technocracy and Meritocracy, then Functional Architecture or Parliamentary System as the third civic
• Origin: Prosperous Unification
• Traits: Intelligent (2), Rapid Breeders (2), Sedentary (-1), Fleeting (-1)
• Ascension: Cybernetic, with The Flesh is Weak as your third perk
• DLC: none

The bonuses all land on the same people. Fanatic Egalitarian gives +10% specialist job efficiency, Meritocracy +10% specialist output, Intelligent +10% researcher efficiency and Materialist +5% research. Technocracy turns your Politicians into Science Directors that make research, and you will see one extra tech each time you pick research. Prosperous Unification starts you with +400 pops and gives 20 years of +10% resources from jobs, +25% amenities and +15% happiness, which will cover a lot of early mistakes.

Rapid Breeders is there because pop growth is the main pain point of 4.x, while Sedentary and Fleeting will barely matter early on. Simply leave the fifth trait pick empty.

• Take Discovery first, build a second science ship and keep your construction ship claiming systems toward chokepoints.
• Settle the habitable worlds near you in the first 10 years while Prosperous Unification carries your stability, and fill specialist jobs first.
• Research Galactic Administration, add Functional Architecture and take Prosperity as your second tradition, then Expansion.
• Build the Research Institute on your capital as soon as you can, which adds +200 Science Director jobs with Technocracy.
• Take Technological Ascendancy and One Vision as your first two perks, and research Integrated Cybernetics in the meantime.
• Before the 20-year bonus runs out, have three or more colonies working. Then take The Flesh is Weak and the Cybernetics tree.

Cybernetic is the easiest ascension for a first game, because it asks for no species design homework, no robot conversion and no Shroud events, and its +20% habitability lets you settle more planet types. Without The Machine Age the Cybernetics tree takes effect directly, and with it the effects wait until the Cyberization situation completes.

The trade-off is a lower ceiling than the other builds here. It leans on research, which means Unity and military come later, and your ascension arrives with the third perk instead of early through an origin. On the plus side, none of these civics locks you in, and you can reform them later.

7. Fun builds

These two are strong as well, but they need more DLC and more attention than the builds above, which is why I would save them for your second or third empire.

Forever Cruise entertainers

Forever Cruise is one of the Nomads origins, and it turns your empire into a pleasure cruise with a crew species and a passenger species. A legal setup is Fanatic Spiritualist and Egalitarian with a Democratic government, Pleasure Seekers and Beacon of Liberty as civics, and Charismatic (2), Intelligent (2), Wasteful (-1) and Deviants (-1) as traits. Sedentary is not allowed for this origin. The plan is to rush three tradition trees, take Mind Over Matter, finish the psionic ascension and form a Covenant with the Instrument of Desire.

Since 4.5, your Entertainers come from the Entertainment Hub specialization instead of the Operations Center. The Instrument’s Exploitation accord costs 150 Zro, first becomes usable 20 years after you form the Covenant, and gives +1% output from all jobs per 100 Entertainers in your empire while it runs. Entertainers, the psionic ascension and the Instrument all buff each other, and once that loop is running the numbers get silly.

It needs Nomads plus Shadows of the Shroud for the Instrument’s accords, it is a little bit fiddly to manage, it swings with the Passenger Satisfaction situation, and it will take a long time to come fully online. A machine version with Rogue Servitor and Tactical Algorithms works too, and since 4.5 its passengers give an extra +1% Complex Drone efficiency.

Shroud-Forged nanites

Shroud-Forged is a Machine Intelligence origin that Rogue Servitors cannot take, and it starts you with 1000 Shroud-Forged pops. The fun part is that you can reject the Animator of Clay and still get psionic ship components. Finish the Reintegration special project and it unlocks the Materiality Engine. Each 20,000-physics cycle of it will materialize one psionic ship tech you do not have yet, Zro launchers included, whatever ascension you took.

For the setup, take Tactical Algorithms and Rapid Replicator with Unitary Cohesion as the third civic, Logic Engines (2) and Bulky (-1) as traits, and Synthetic Age into Nanotech for the ascension. It needs Shadows of the Shroud and The Machine Age. It does take a while to get off the ground, and you cannot plan which psionic component the Engine hands you first.

Builds that stopped working in 4.5

If you are following an older guide or video, these are the setups that no longer do what they promise:

• Experimental Sentencing psionic rush. It was the loudest psionic build of the 4.5 beta, but 4.5.2 halved Experiment Engineer output to 1 of each research, with their upkeep halved to match, and fixed the exploit where high-level councilors turned Test Subject losses into extra pops. The civic is still a decent research pick for authoritarian or xenophobe empires, just not the build to copy.
• Red Giant Fire Cult rush. 4.5.2 changed Fire Cult from extra Unity to job efficiency for Fire Dancers, based on the habitability of each pop group, which makes the older Fire Cult rush guides outdated.
• Military Arkship weapon stacking. Each weapon zone now gives only +1% weapon damage per 100 Soldiers or Knights, down from 5% in the 4.5 beta, and Knights got +0.15 alloys and +0.15 consumer goods of upkeep in 4.5.
• Feeding the Behemoth. Killing, breeding or capturing fauna and bio-ships gives the Behemoth crisis only a fifth of its old progress since 4.5. The Wilderness payoff still works, but the fast growth is gone.
• Pre-4.0 slaver economies. Since 4.1, Slaver Guilds no longer enslaves a fixed share of your population and instead treats your Workers as if they were enslaved, with +15% job efficiency for slaves. Builds from before 4.0 were also made for a pop system that 4.0 replaced.

Common questions

Which build should a beginner play?

The Prosperous Technocrats build above, which needs no DLC. The premade United Nations of Earth plays in a similar way if you want a ready-made empire for your first game. Once you own MegaCorp and The Machine Age, the lighter Cybernetic Creed megacorp makes a great second empire, because it is very hard to get wrong.

What is the best build without DLC?

Of the builds on this page, only the beginner build runs on the base game alone. Its ascension perks and Cybernetic ascension have been part of the base game on PC since 4.3.6, and so have Rogue Servitor and Machine Intelligence, but the machine build’s Virtual ascension needs The Machine Age.

Is tall viable in 4.5?

Not in the old sense, because a wide empire with the same civics will still out-scale a tall one, and even a tall empire needs to expand some.

What does work is a low-sprawl empire with a few colonies built up fully, plus income that needs no pops, such as starbases, space deposits and research stations. Shattered Ring from Federations is the origin I would use for it, since it hands you a large ring-world homeworld to repair segment by segment, and my ring world guide explains how the segments work. The research core of the beginner build carries over well, and Synthetic ascension into the Virtual form suits a low colony count. Check the Virtual tooltip before you commit, and take the physical form or Cybernetic if its numbers do not suit your empire.

What is the best origin for a strong build?

• Knights of the Toxic God for the strongest overall economy and the best conquest base.
• Cybernetic Creed for a strong empire that is easy to run, with an ascension that needs no perk.
• Wilderness for the biggest late game, through Behemoth Fury and Mind Meld.
• Teachers of the Shroud for a psionic empire that skips Mind Over Matter.
• Prosperous Unification if you have no DLC, for +400 pops and 20 years of +10% resources from jobs.

For a full ranking of every origin, see my Stellaris origins tier list.

How do you make a good build in 2026?

On the current 4.5.2 patch, the strong builds above share a few habits. They pick one job and stack ethics, civics and traits on it, the way the Knights and the Haruspex builds do, and they plan the ascension from day 1, because rushing ascension is where most of the power sits in 4.x. Organic species get 2 trait points and 5 picks, machines get 1 point, and negative traits give points back. Ethics have 3 points, with a fanatic ethic costing 2, and you will get 2 civics at the start and a third from Galactic Administration.

Check the authority locks before you start. Fanatic Egalitarian forces Democratic, Fanatic Authoritarian forces Dictatorial or Imperial, and civics like Citizen Service or Exalted Priesthood only work under certain authorities. Then plan the upkeep behind your main job, meaning consumer goods for the Haruspex and alloys for Knights.

What are the best ethics?

There is no single best ethic, but Egalitarian and Spiritualist appear most often in the builds on this page. Egalitarian gives +5% specialist job efficiency, or +10% as a fanatic ethic, and unlocks the Utopian Abundance living standard. Spiritualist gives +10% Unity, or +20% as a fanatic ethic, and is required for Cybernetic Creed, Teachers of the Shroud and civics like Exalted Priesthood. Materialist adds +5% research and is needed for Technocracy, Militarist is there for Citizen Service and fire rate, and Gestalt Consciousness takes all three ethic points for hive minds and machines.

Personally, I would pick the ethics last, after the job you want to stack, because your civics and origin will usually decide them for you.
