---

Traits personalize and add flavor to your colonists by granting a wide variety of special bonuses or conditions to their day to day activities, and so encourage more complex player-conceived stories based on those individual characters. Traits provide physical or psychological abilities or limitations, likes/dislikes, behavior tendencies, personality quirks, and so on. Some are beneficial, some are harmful to the colonist or your colony as a whole. Some are constant, some only rarely triggered. Some can be more or less easily negated or manipulated to your advantage by catering to them (or denying them), others are more problematic or outright dangerous.

General traits

These traits are generalized into groups, organized roughly by topic but there are no such groupings laid out formally in the game. There are no relations or prohibitions between traits grouped together here unless noted (e.g. a colonist cannot be both "ascetic", wanting a minimal bedroom, and "jealous" of those with better bedrooms).

Spectrum traits

Theses are groups of related traits, that are inter-related and grouped by degree, creating a "spectrum" of good/bad/better/worse in that specific sphere of behaviour. A colonist can only have one trait from any single related spectrum for these traits, defining whether they are notably outside the norm for, for example, movement speed, or drug interest, or their physical (un)attractiveness.

Drug desire

These traits affect a colonist's likelihood to consume drugs.

Note that despite the common misconception, chemical fascination and interest pawns no longer randomly go on drug binges independent of mood.

Beauty

Main article: Beauty (Pawn)

These traits influence a colonist's appearance and how it affects other colonists' opinions of them - as well as sexual attractiveness.

Each point of beauty corresponds to +20 opinion from other colonists, e.g. a colonist with 2 beauty will have +40 opinion, while another with -1 beauty will have -20.

Creepjoiner traits

These traits are part of the Anomaly DLC and cannot be randomly assigned to pawns. They are normally found on creepjoiners, and therefore have powerful positive or negative effects to balance out the other strengths and weaknesses creepjoiners have.

Positive traits

These traits are considered benefits, to compensate whatever mysterious downside haunts the creepjoiner.

Name	Description	Effect
Perfect Memory	NAME has outstanding memory, both in terms of retaining information but also muscle memory. His/Her skills will never decay.	Skills cannot decay

Negative traits

These traits are downsides, meant to counterblance the creepjoiner's powerful benefits. Note that, unlike most other creepjoiner drawbacks, these traits are never hidden; as such, you be assured there are no other nasty surprises waiting for you.

Name	Description	Effect
Disturbing	NAME is a peculiar person who seems fixated on horrendous ideas. Talking to {PAWN_objective} is often upsetting.
