Source note: Part 2 of the Stellaris 3.14 “Circinus” cheat sheet. Tier letters follow the community guide by Argure (based on Montu Plays’ tier lists), cross-checked against the Stellaris Fandom wiki and community discussions. Part 1 covered empire creation (ethics, origins, civics). This part covers the choices you make during the campaign.
Part 1 covered the choices you lock in before unpausing — ethics, origin, civics, authority. Part 2 covers the choices that define the middle and late game: which ascension path you commit to, which tradition trees you adopt, and which ascension perks you spend on them. These are the decisions that turn a generic empire into a specialized powerhouse — or a dead end.
What it covers: All four ascension paths, every tradition tree, and every ascension perk, rated. Why it matters: These mid/late-game picks turn a generic empire into a powerhouse or dead end. Who should pick this: Stellaris players deciding path, tradition order, and perk order.
Ascension Paths
An ascension path is the single biggest transformation your empire can undergo. You pick one via an ascension perk (tier 1), which unlocks a special ascension tradition tree. There are four paths, and they are mutually exclusive — pick one and commit. Some origins (Teachers of the Shroud, Cybernetic Creed, Synthetic Fertility) lock you into a specific path; the rest are open.
The four paths, in community-consensus strength order:
Ascension Path Comparison
| Path | Tier | Perk tier | Best for | Key payoff | Weakness |
|---|---|---|---|---|---|
| Cybernetic | S | T1 | General use, trade, wide | +10% global output, +5% specialist output, +40yr lifespan, +20% habitability, −10% upkeep — all from the tradition + assimilation alone, before traits. Cheap perk, cheap modding. | Niche without a trade or habitability build. |
| Genetic | S | T1 | Slavery, conquest, min-max, Hive Minds | Clone Vats, +2 mod points, biological ascension traits (Erudite, Robust, Nerve Stapled), per-planet subspecies specialization. Best minmax ceiling. | High micro; no global output bonus (only Robust +5% for 4 points); conquered/immigrated pops don’t auto-assimilate. |
| Psionic | A | T1 | Tall, rush, spiritualists, ship supremacy | Latent→Psionic pops, Psi Corps, Shroud covenants (Composer of Strands is strongest), Chosen One leader, best ship techs (Psi Shields, Psi Jump Drive, Precog computers), +115% pop output from telepaths on a Sanctuary world. | Weakest pop growth; RNG-dependent (mitigated by Teachers of the Shroud); locked to Spiritualist flavor. |
| Synthetic | B | T1 | Machine empires, ease of use, lategame | Immortal leaders, +10% robot output, assimilate everyone into one species (removes species lag), perfect habitability. The strongest lategame trait (Under One Rule). | Comes online very late; assimilation resets species to unmodded (post-3.6 bug); Spiritualist FE declares war on you. |
The four paths in detail
Cybernetic is the community’s pick for best general-use path. The Cybernetic tradition + assimilation alone grants +10% global output, +5% specialist output, +40 years leader lifespan, +20% habitability, and −10% pop upkeep — before you add a single cyborg trait. The perk is tier 1 (cheap), the ascension project is cheap, and pop-modding special projects are extremely cheap. Cyborg traits are flexible: double trade value, double research, whatever you want. It has a built-in pull toward Materialism, which makes conquered Spiritualist pops easy to manage. Recommended for general use — especially trade builds (stack Thrifty + Trading Algorithms for 1.25×→1.5× trade) and wide playstyles.
Genetic is the minmax ceiling. You get Clone Vats (+1.5 organic pop assembly), +2 genetic modification points, and access to biological ascension traits: Erudite (researcher output, leader bonuses), Robust (+5% all output, +30yr lifespan, +30% habitability), Nerve Stapled (for slaves), Delicious (for livestock). You can create a dedicated subspecies for every job — research pops, mining pops, alloy pops — each perfectly tailored. The catch is micro: conquered and immigrated pops don’t auto-assimilate, so you’ll spend decades gene-modding them, and the special project costs stack. Recommended for slavery/conquest builds and Hive Minds (hives don’t care about trade). Pairs exceptionally with the Overtuned origin for absurd trait stacking.
Psionic is the rush and tall path. It comes online fast (especially with Teachers of the Shroud), and its pop efficiency is unmatched: a Sanctuary world with telepaths can hit +115% pop output, and a single forge Ecumenopolis can crank 5k+ alloys. The Shroud grants the best ship techs in the game — Psi Shields, Psi Jump Drive (longer range), Precog computers (tracking). A Chosen One admiral is a fleet unto itself. The weakness is pop growth (psionics get none) and RNG: the Shroud is a slot machine, though covenants are no longer strictly random in 3.6+ and the Composer of Strands is the reliable strong pick. Recommended for spiritualists, tall play, and rush builds.
Synthetic is the lategame power and ease-of-use path — and the only real option for most Machine empires. You turn all organic pops into synths: immortal leaders, +10% robot output, perfect habitability everywhere, and you can assimilate the entire galaxy into one species (eliminating the notorious species lag). The downside is timing: the required techs (Synthetics) can take decades to roll, and post-3.6 assimilation resets pops to an unmodded template, so late-game modding projects stack to extreme durations. A Spiritualist Fallen Empire will also declare a humiliating war on you when you ascend. Recommended for Machine empires and players who want a simple, powerful lategame. It also offers the strongest lategame trait via the Under One Rule origin.
Which path should I pick?
- Unsure / general use → Cybernetic. Strong, cheap, flexible, no hard counters.
- I want to micro and minmax → Genetic. Highest ceiling, especially with Overtuned or slavery.
- I’m Spiritualist or want to rush/tall → Psionic. Best ship techs, best pop efficiency, fast online.
- I’m a Machine empire or want it simple → Synthetic. Immortal leaders, assimilate everything, strongest lategame.
Tradition Trees
Traditions are adopted one tree at a time, costing Unity. Each tree has an adoption bonus, several perk tiers, and a completion bonus. Completing a tree grants one ascension perk slot. In 3.1+, you choose which trees to adopt rather than filling a fixed set — so tradition order is a real decision.
There are base-game trees, expansion trees (gated by DLC), and ascension trees (gated by ascension perks). Below are all of them, rated.
Base & Expansion Tradition Trees
| Tradition | Tier | DLC | Best for | Key bonuses |
|---|---|---|---|---|
| Enmity | S | Grand Archive | Rivalry / hostile neighbors | Rivalry-focused bonuses; strong when surrounded by enemies. |
| Expansion (Void Dwellers) | S | — | Void Dweller tall | For Void Dwellers specifically; habitat-focused bonuses. |
| Mercantile (trade builds) | S | — | Megacorps, trade empires | For trade-focused empires; Consumer Benefits + Marketplace of Ideas policies. |
| Supremacy | S | — | War / military | Ship build cost/speed, fire rate, naval capacity, war doctrines on completion. Near-essential for any war. |
| Virtuality | S | The Machine Age | Machine, virtual ascension | Machine-specific virtuality bonuses. |
| Adaptability | A | — | Habitability / general | +10% habitability, +10% food, −33% resettlement cost. |
| Discovery | A | — | Tech rush | +35% survey speed, +1 research alternative, +20% anomaly research, +10% research speed on completion. The classic first pick. |
| Domination (Gestalt) | A | — | Gestalt wide | For Gestalt empires; influence, worker output, edict fund. |
| Harmony | A | — | Stability / unity | −10% pop upkeep, +25% governing ethics attraction, +5 stability, +25% planetary ascension effect. |
| Modularity | A | The Machine Age | Machine, modularity | Machine-specific modularity bonuses. |
| Nanotech | A | The Machine Age | Machine, nanotech | Machine-specific nanotech bonuses. |
| Statecraft | A | Galactic Paragons | Council / agendas | +20 edict fund, agenda speed/duration, +1 effective councilor level on completion. Underrated — nearly always-on agenda bonuses. |
| Synchronicity (Gestalt) | A | Utopia/Synthetic Dawn | Gestalt unity | For Gestalts; unity, lifespan, edict fund. |
| Cybernetics | B | Utopia | Cybernetic ascension | The ascension tradition for Cybernetic path. |
| Diplomacy | B | — | Federations | Federation creation, envoys, trust. Useful only for federation play. |
| Expansion (general) | B | — | Wide | Colony development, starbase influence cost, pop growth. Good early for wide. |
| Mercantile (general) | B | — | Trade | +1 trade value per clerk, trade policies, merchants. |
| Prosperity | B | — | Economy | −10% build cost/upkeep, +5% specialist output, +5% resources from jobs on completion. Megacorp go-to. |
| Psionics | B | Utopia | Psionic ascension | The ascension tradition for Psionic path. |
| Unyielding | B | Apocalypse | Defense / starbases | Starbase capacity, defense platforms, orbital bombardment resistance. Situational. |
| Versatile | B | Synthetic Dawn | Machine general | Mishmash of diplomacy/harmony/prosperity for machines. |
| Domination (general) | C | — | Wide / influence | Influence, worker output, edict fund. Outclassed for non-gestalts. |
| Subterfuge | C | Nemesis | Espionage | Codebreaking, cloaking, infiltration. Espionage has hard scaling caps — falls off fast. |
| Synchronicity (general) | C | Utopia/Synthetic Dawn | Gestalt | Slightly better than Harmony for gestalts but still weak. |
| Synthetics | C | Utopia | Synthetic ascension | The ascension tradition for Synthetic path. Weakest ascension tree for non-machines. |
| Aptitude | F | Galactic Paragons | Leaders | Leader upkeep, exp, capacity. Leader bonuses are nice but not tree-worthy alone. |
| Genetics | F | Utopia | Genetic ascension | The ascension tradition for Genetic path. (Rated low as a standalone tree, but mandatory if you take the Genetic perk.) |
| Politics | F | Federations | Galactic Community | Envoy + influence per envoy in GC, resolution bonuses. Only if you’re gunning for Galactic Emperor. |
Ascension Tradition Trees (gated by ascension perks)
These are unlocked by taking the corresponding ascension perk. They operate like normal traditions but are far more playthrough-defining. All require the Utopia DLC.
| Tree | Unlocked by | Tier | Notes |
|---|---|---|---|
| Cybernetic | The Flesh is Weak / Organo-Machine Interfacing | S | Best of both Genetic and Synthetic. Special project gives all pops the Cybernetic trait; cyborg traits; Assembly Standards policy. Fits almost any build. |
| Genetic | Engineered Evolution | S | Clone Vats, +2 mod points, biological ascension traits, Leviathan Transgenesis on completion. Best minmax. |
| Psionic | Mind over Matter | A | Latent→Psionic, Psi Corps, Shroud entry, covenants. RNG mitigated in 3.6+. |
| Synthetic | Synthetic Evolution / Synthetic Age | B | +25% leader exp, +1 level cap, turn organics mechanical. Must-pick for Machine empires; roundabout for others. |
Recommended tradition order
There’s no single correct order, but here are strong openers by playstyle:
| Playstyle | Recommended order |
|---|---|
| Tech rush | Discovery → Expansion → Prosperity → (ascension tree) → Supremacy |
| Wide/conquest | Expansion → Supremacy → Domination → Prosperity → (ascension tree) |
| Tall/Void Dwellers | Expansion (Void Dweller variant) → Discovery → Prosperity → Mercantile → (ascension tree) |
| Megacorp/trade | Mercantile → Prosperity → Diplomacy → Statecraft → (ascension tree) |
| Spiritualist/unity | Harmony → Discovery → Statecraft → (Psionic tree) → Supremacy |
| Gestalt | Synchronicity → Expansion → Supremacy → Domination (gestalt) → (ascension tree) |
Discovery first is the classic safe opener — survey speed and anomaly bonuses are invaluable early, and the +10% research speed completion bonus stays strong all game. Supremacy is near-mandatory if you expect war. Statecraft is sleeper-strong: its agenda speed/duration lets you keep a powerful agenda running nearly constantly, which compounds with whatever your council is good at.
Ascension Perks
Ascension perks are unlocked by completing tradition trees. Tier 0 perks are available immediately; tier 1 requires 1 prior perk, tier 2 requires 2, tier 3 requires 3. You have limited slots, so every pick matters. Below are all perks, rated.
Top Ascension Perks
| Perk | Tier | Perk tier | DLC | What it does |
|---|---|---|---|---|
| Synthetic Age | SSS | T2 | Synthetic Dawn | (Machine only) +2 machine mod points, −33% modding cost. The single highest-rated perk for machine empires. |
| One Vision | S+ | T0 | — | −10% pop amenities usage, +10% monthly unity, +50% governing ethics attraction. Excellent generic opener. |
| Arcology Project | S | T2 | MegaCorp | Create Ecumenopoli — the endgame of alloy/CG production. A single forge Ecu can supply your entire alloy need. |
| Colossus Project | S | T3 | Apocalypse | Unlocks the Colossus + Total War casus belli. Take it for the CB, not the ship (unless you’re a Driven Assimilator or Hydrocentric — their world-killers are insane). |
| Cosmogenesis | S | — | The Machine Age | Machine-age crisis path. Defies ranking — unique playstyle. |
| Defender of the Galaxy | S | T3 | — | +50% damage to endgame crisis + Grey Tempest, +200 opinion from all empires. The crisis insurance perk. |
| Galactic Nemesis | S | — | Nemesis | Become the Crisis path. Unique playstyle; defies ranking. |
| Hive Worlds | S | T2 | Utopia | (Hive Mind) Hive World terraforming. The hive-mind version of an Ecumenopolis — even more valuable given fewer options. |
| Machine Worlds | S | T2 | Synthetic Dawn | (Machine) Machine World terraforming. Good, not great — you can already ignore habitability. |
| Master Builders | S | T2 | Utopia | +1 megastructure build capacity, +50% build speed. Take if you unlock Mega-Engineering before 2350. |
| Mind over Matter | S | T1 | Utopia | Opens the Psionic ascension path. Must-pick if you roll the Zroni precursor. |
| Organo-Machine Interfacing | S | T1 | Utopia | (Gestalt) Opens the Cybernetic path for hive/machine. |
| The Flesh is Weak | S | T1 | Utopia | Opens the Cybernetic path for normal empires. The best of both Genetic and Synthetic. |
| Engineered Evolution | A+ | T1 | Utopia | Opens the Genetic ascension path. |
| Galactic Force Projection | A+ | T2 | — | +20 fleet command limit, +80 naval capacity. Strong if you need the fleet. |
| Imperial Prerogative | A+ | T0 | — | −50% empire size from planets. (Not available to megacorps — a shame.) |
| Nihilistic Acquisition | A+ | T0 | Apocalypse | Raiding bombardment stance — steal pops from besieged planets. Great for slavers/necrophages. |
| Technological Ascendancy | A+ | T0 | — | +10% research speed, +50% rare tech chance. The classic first pick. |
| Galactic Wonders | A | T3 | MegaCorp/Utopia | Unlocks Ring World, Dyson Sphere, Matter Decompressor research. Powerful but you’ll often not need them by the time you can take it. |
| Galactic Contender | B | T3 | — | +33% damage to fallen/awakened empires. By the time you need it, you don’t. |
| Lord of War | B | T0 | Overlord | +1 mercenary enclave capacity, +25% diplo weight from fleet power. |
| Mechromancy | B | — | The Machine Age | Machine-age perk. |
| Voidborne | B | T0 | Utopia | +20% habitat habitability, +2 habitat building slots. Zero-brainer for Void Dwellers. |
| World Shaper | B | T1 | — | −25% terraforming cost, Gaia World terraforming. Good for Life-Seeded/Shattered Ring. |
| Xeno-Compatibility | B | T0 | MegaCorp | +33% immigration pull, +20% growth on multi-species worlds, hybrid species. Memes aside, it’s a “lose control of pop growth” button — has a dedicated disable option. |
| Eternal Vigilance | B− | T0 | — | Starbase/defense platform bonuses. Only if boxed in by genocidals. |
| Consecrated Worlds | C | T0 | — | (Spiritualist) Consecrate up to 3 worlds for unity/amenities. RNG-dependent. |
| Grasp the Void | C | T1 | — | +5 starbase capacity. A waste. |
| Hydrocentric | C | T0 | Aquatics | (Aquatic) −25% ocean terraforming, expand ocean worlds, DELUGE Colossus. S-tier if you’re Aquatic — the guide rates it C in a vacuum but it’s mandatory for ocean builds. |
| Mastery of Nature | C | T0 | — | −33% blocker clear cost, +2 max districts decision. Vastly outshadowed. |
| Universal Transactions | C | T0 | — | (Megacorp) −15% branch office cost, free commercial pacts. Strong for megacorps but the guide rates it low. |
| Archaeo-Engineers | F | T0 | Ancient Relics | Archaeotech weapon/building bonuses. Jank system. |
| Detox | F | T0 | Toxoids | Terraform toxic-candidate worlds. Underwhelming. |
| Shared Destiny | F | T0 | — | −100% loyalty penalty from multiple subjects, +2 envoys. Contentious. |
| Transcendent Learning | F | T0 | — | +2 leader level cap, +50% leader exp. Outclassed by other leader sources. |
| Enigmatic Engineering | F− | T1 | Apocalypse | +2 cloaking, +2 encryption, no debris. Almost never sees use. |
| Executive Vigor | F− | T0 | — | +100 edict fund. Outshadowed. |
| Interstellar Dominion | F− | T0 | — | −20% claim/starbase influence cost. Moot once you have Colossus + Total War. |
