Traits represents a species' innate functions, abilities and personality. A species's traits are selected at the start of a new game, but a species or certain pops of a species can adapt new traits through genetic engineering or occasionally events. Traits affect a wide variety of areas, from population growth rate to resource output to lifespan or even how pops are viewed by other aliens. Most traits come in mutually exclusive groups that affect the same aspect of the species, such as Nomadic.png Nomadic and Sedentary.png Sedentary, and each pop can only have one such trait from the group at any given time. These groups include traits with opposite effects, as well as stronger variants of a trait. Though traits are initially decided at a species level, individual pops of the same species can end up with different traits with genetic modification, producing new subspecies or variants. This rarely happens without player intervention.

Traits are mostly fixed at the start of the game. Altering traits during the game is generally possible only later in the game through some select events or by using genetic engineering. Certain technologies and Ascension Perks add additional trait points that can be used to alter a part of your species' pops; modifications can range from altering their planet habitability to adding an additional positive trait or removing a negative one.


Organic traitsEdit

Traits are purchased from a points pool, with 2 points being available at the start of the game. Some traits are negative and have a negative cost, refunding points into the pool. Each species is limited to a maximum of 5 traits; non-standard traits do not count against this limit. Non-standard traits are all traits that have a cost of zero.

Initial traitsEdit

Initial traits are available when first creating a species. They can all be changed later via genetic modification. Initial traits can be both positive and negative, with the two being mutually exclusive. Traits that affect   Happiness cannot be added to species with the   Hive-Minded trait.

Origin traitsEdit

Origin traits can only be given by certain Origins. The   Serviles trait can be removed after researching the   Genetic Resequencing technology but other origin traits are permanent. All origin traits have a 33% chance of being inherited by hybrid species.

Special traitsEdit

These traits are required for special cases of species and cannot be removed from the creation menu.

The   Hive-Minded trait can only be added by hive mind empires and can only be removed by empires that are not hive minds. Pops with this trait in an non-Hive Mind empire will slowly die while pops without the Hive-Minded trait in a Hive Mind empire can only be displaced, purged or used as livestock.

Special traits that cost trait points can be removed via the biological ascension path. Special traits that do not cost trait points have a fixed chance of being inherited by hybrid species.

Climate preference traitsEdit

Each organic species has a climate preference trait that determines their base   Habitability on the various types of planets, usually that corresponding to the type of their homeworld. Habitability traits can be changed through genetic modification, but a pop can never have more than one Habitability trait. The Habitability of other celestial body types is unaffected by these traits.

Preference Climate   80% Habitability   60% Habitability   20% Habitability

Exotic climate preferencesEdit

Exotic climate preferences can only be obtained through Origins, events, conquest of a unique species or when the   Omnicodex relic creates a species on a matching celestial body.

Robotic traitsEdit

All Robotic Pops have either the   Mechanical or the   Machine trait. Both traits grant +200%   Habitability on all planets.   Mechanical Pops can exist within   Machine Intelligence empires via conquest but   Machine Pops cannot exist outside   Machine Intelligence empires. All Robotic Pops can then be given new traits through Robomodding, a few of them being restricted to   Mechanical or   Machine pops. Robotic Traits can be both positive and negative, which are mutually exclusive with each other, and both of them can be added and removed at will once the technology to enable Robomodding becomes available.

Empires that are not   Machine Intelligence must research higher tiers of robot technologies before they can add some of the more powerful traits to Robot Pops.
