Traditions are abilities or bonuses unlocked with the unity resource. Traditions can be seen as a representation of the socio-cultural evolution of the empire as it expands and develops. Traditions help define an empire by allowing the adoption of traditions trees that suit its particular play-style. Completing a tree allows the empire to pick an ascension perk to further enhance themselves.
Traditions are grouped into 7 Tradition Trees.
- Each tree must be adopted before the individual traditions can be adopted. Adopting the Tradition Tree grants the Adoption Effect.
- Adopting a Tradition grants its abilities and bonuses and unlocks the Traditions it linked to.
- Adopting all 5 Traditions in a tree grants the Finisher Effect, as well as an Ascension Perk slot.
Some empires have some traditions, or even entire tradition trees, that don't fit the empire by flavor and/or playstyle, swapped into other traditions. Authorities and Civics that can cause tradition swapping can normally only be picked during the empire creation phase and cannot be removed or replaced after the game starts by usual mean.
For example, the A New Life tradition grants +10% Pop growth speed, but Machine Intelligence empires makes little use for this effect and will have it swapped into +10% Pop Assembly Speed that better fit their playstyle.
This page does not show tradition swaps that involve only narrative changes to the names and flavor texts.
The cost of unlocking a tradition depends on how many traditions the empire has already unlocked as well as whether the Empire Sprawl is larger than Administrative Capacity. The tradition cost formula is the following:
An empire has completed one tradition tree and opened another, for a total of 8 unlocks (5 + 2 opens + one extra for finisher) and 2 open trees. Their empire size is 3 over their limit.
Note: Adopting and completing a tree both increase the unlocked traditions factor by 1.
There are 7 Tradition trees and each of them has a theme.

Discovery traditions are focused around research and space exploration. It grants bonuses to research and improves the performance of scientists and science ships.
Finishing an entire tradition tree or acquiring the Ascension Theory technology unlocks an ascension perk slot. Ascension perks can be viewed as defining characteristics that emerge as a product of with the socio-cultural evolution represented by the Traditions intertwining with the empire's identity (its Ethics, Civics, Government and Population). Ascension perks represent the empire's greater-scope ambition(s) and, in the case of the three Ascension paths, its ultimate final fate.
Ascension perks often favor either a tall or wide gameplay, with some that allow access to gameplay mechanics not available through Traditions alone. This includes the three ascension paths, the ability to build deep-space megastructures, the ability to use terraforming to create special planets and other powerful abilities. An empire can have up to 8 Ascension perks.
Due to the difficulty of unlocking an ascension perk slot, it is prudent to delay making a choice, especially if the desired perk cannot be selected if any required technologies have not been researched yet. In addition, once chosen, the Ascension perk is permanent and cannot be changed.
Tier 0 ascension perks can be taken from the start. Tier 1 ones require 1 previous ascension perk, tier 2 ones require 2 previous ascension perks and tier 3 ones require 3 previous ascension perks.

- The formula variables can be found at under tradition cost.
- Leader malfunction events are triggered on a decade pulse. With this tradition, each bad event has a 50% lower weight. Since the weight for no event is unchanged, the probability of a bad event is actually reduced to 53.17% of normal.
- If Federations DLC is installed, Barbaric Despoilers can create federations but limited to Martial Alliance and Hegemony. Otherwise, Barbaric Despoilers will just have the regular variant of this Adaptability tradition and cannot create federations.
