Traits

Version

This article has been verified for the current PC version (2.8) of the game.

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 and 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 traits

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 traits

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.

Lithoid traits

Lithoid traits are only available to species with the Lithoid archetype. The Lithoid trait is always present on such species.

Origin traits

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.

Serviles	Happiness +10% Resources from Jobs +10% Cannot be employed in Ruler or Specialist Jobs Cannot generate Leaders	Intelligent Erudite Natural Physicists Natural Sociologists Natural Engineers	1	Syncretic Evolution	This species evolved alongside a second, more advanced species. Never particularly intelligent to begin with, selective breeding for physical prowess and docility has reduced them to servile proles.

Special traits

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.

Biological ascension traits

There are 5 advanced traits which are made available for genetic modification if the Evolutionary Mastery ascension perk is taken and Genetic Resequencing has been researched. Biological ascension traits are only half as likely as standard traits to be inherited by hybrid species.

Pre-Sapient traits

Pre-Sapient species have exclusive traits that cannot otherwise be chosen when creating or modifying a species. They retain these traits after being uplifted as a sapient species. All of these traits cost 1 trait point.

Type	Effects	Description

Climate preference traits

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
Arid	Dry	Arid	Desert Savannah	Frozen Wet
Desert		Desert	Arid Savannah
Savannah		Savannah	Arid Desert
Alpine	Frozen	Alpine	Arctic Tundra	Dry Wet
Arctic		Arctic	Alpine Tundra
Tundra		Tundra	Alpine Arctic
Continental	Wet	Continental	Ocean Tropical	Dry Frozen
Ocean		Ocean	Continental Tropical
Tropical		Tropical	Continental Ocean

Exotic climate preferences

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.

Preference	Habitability on native climate	Habitability on regular planets	Source
Tomb	80% Tomb	60%	Pre-FTL or pre-sapient species inhabiting a Tomb World Horizon Signal event A New Species event on a Tomb World
Gaia	100% Gaia	0%	Pre-FTL or pre-sapient species inhabiting a Gaia World Life-Seeded Origin Baol pops created by Nu-Baol Life Seeding decision
Ring	100% Ring World	0%	Sanctuary pre-FTL civilizations
Habitat	100% Habitat	0%	Void Dwellers Origin Marauder and Enclave pops
Relic	80% Relic	0%	Pops created by the Omnicodex relic on a Relic World or an Ecumenopolis

Robotic traits

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.
