Traits

Version

Outliner top.png
This article is considered accurate for the current version (2.3) of the game.

This article is for the PC version of Stellaris only.

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.

Biological 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.

Initial traitsEdit

Initial traits are available when first creating a species. They can all be changed later via genetic modification.

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.

Habitability traitsEdit

See also: Planets

Each organic species also has a Habitability trait that determines their base habitability on the various types of worlds, 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   Gaia worlds, Ecumenopolises,   Habitats, Ringworlds,   Machine Worlds, Hive Worlds and (except for pops with a preference)   Tomb Worlds is unaffected by these traits.

Robotic traitsEdit

Outside   Machine Intelligence empires Robots always start only with the   Mechanical trait, which gives them   +200% Habitability on all habitable planets and structures. They can then be given new traits through Robomodding. A few of them are restricted to   Mechanical or   Machine pops.
