Summary
Character traits say a lot about yourRimWorldcolonists. Whether they’re happy, sad, enjoy socialising or being alone, or are simply morally questionable. With everygreat colony sim, you want the traits and bonuses that make your colonists work harder and faster.
Some traits are better to avoid. Traits like Chemical Fascination mean you have to cater to colonists’ needs to keep them happy. These traits are generated randomly, so there’s no picking and choosing. You’ll have to keep an eye out for the good ones. With that in mind, here are the best character traits for your colonists.

Trait Impact
Permanent Mood Buff +12
Happiness is a crucial aspect of RimWorld. Unhappy colonists can experience mental breaks that stop them from doing their tasks. There are lots of factors that change a colonist’s mood. You canincrease them in various ways, but the Sanguine trait is always a helpful addition.
The trait gives an additional 12 points to a colonist’s mood permanently. That means, no matter what your colony goes through, Sanguine will constantly be there to improve their mood. It’s a valuable trait when your colony is having a hard time; it prevents a colonist from suffering a mental break, so they can keep working.

Move Speed +0.40
Movement speed is a beneficial addition to have. It makes your colonists work faster, arrive at major events quickly, and keeps them safe when running away from enemies. An increase of 0.40 might not seem like much, but it will when you see them racing against your other colonists.
When you progress further, you’ll have access to bionic and archotech improvements that can increase the performance of your colonist’s limbs. With this, you’re able to potentially have a speedy colonist with archotech legs and a movement boost. That could be handy in any time-sensitive situation.

Global Learning Factor +75%
Your colonists are learning a skill almost every time they complete a task. Ideally, you’ll have colonists working on things they’re passionate about. Passionate skills increase quicker, and your colonists will be happier when carrying out the task.
Fast Learner is a great trait that increases the learning speed of your colonist. This trait means your colonists can pick up a skill quickly and, once they’re at a higher level, will produce higher-quality items. It also means that, if your colonists start to lose their skills, it won’t take long to get them back on track.

Skills Never Decay
Perfect Memory is a trait that prevents your colonist from forgetting a skill. Forgetting a skill will happen when your colonist gets to higher levels. Seeing all that progress go to waste can be frustrating, but your colonists can’t be good at everything.
Or can they? The Perfect Memory trait stops the skill decaying, so your colonists will never forget a skill again. This can be great if you have skills that aren’t utilised as much later in the game. If anything goes wrong, your colonists will be fine picking themselves back up with their expert skills.

Global Work Speed +35%
Everyone wants someone who works harder and faster. Industrious is a trait that makes your colonists work harder to finish their tasks. They’ll complete tasks faster than your other colonists, so assigning them to something that needs doing fast is always good.
This trait can be good for doctors who need to tend to patients quickly or for construction workers who need to expand or rebuild the colony before a threat arrives. Industrious is a practical trait for every part of the game; its use will depend on your colony’s most pressing matter.

Never mind the sight of blood or death
Bloodlust means your colonist is happy seeing bloody fights and rotting bodies all over the place. It’s a gruesome trait to have, sure. However, it’s one of the better traits for a game like RimWorld, where peace isn’t ever an option.

The trait will boost your colonist’s mood whenever they kill someone or witness a death. Since death often happens, it’s almost like having a permanent increase in your colonist’s mood. It also means they won’t be upset at the sight of dead bodies, or a room filled with blood. Weirdly, they’d probably enjoy the decoration. The only downside is that they’re more likely to start a social fight, so keep a trained doctor in the colony and you’ll be fine.
Immunity Gain Speed +30%
Your colonists will, at some point, be in danger of dying of some kind of sickness or infection. If their ailment reaches 100 percent before their immunity does, they’ll die. The Super-Immune can help you avoid that by increasing the immunity gain speed.
This trait is one of the ideal ones as it allows you to relax while your colonist is healing. Immunity tends to be based on many things, including the state of the hospital room, the quality of the medicine used, and the tend quality when treated by a doctor.

Mental Break Threshold +12%
Global Certainty Loss Factor +50%
Too Smart is a worthwhile trait for any colonist. It increases the colonists' learning rate, so they can gain expertise in their skills quickly. It also increases their mental break threshold, meaning they’re more mentally stable than other colonists. These traits can help your colonist work faster and increase their skills while staying happy.
The one downside to the trait is the global certainty loss factor. This is an ideology addition and determines how much certainty your colonist loses in their faith when being converted. If you’re focusing on your ideology, it can cause some havoc. Having solid, religious celebrations should be enough to counter it.

Incoming Damage Multiplier x50%
Colonists need to be able to take a beating, which is why Tough is a smart choice for a fighting colonist. Tough increases the incoming damage multiplier, which means they can take less damage when being hit. You’ll almost always be dealing with some danger, so having a colonist who can take a hit can make all the difference in the front lines.
Later on, when you’ve advanced your colony, you can equip them with even more protection, like marine or recon armour. You can rest assured knowing that those colonists can beatmore challenging enemiesin a fight, especially if they can protect more vulnerable members.

Rest Rate Multiplier +50%
We all need sleep, colonists included, annoyingly. Sleep is essential in RimWorld unless you want your colonist to pass out from exhaustion and be mad at you for it. Lack of sleep can make them unhappy and stop them from completing tasks in favour of getting some shuteye.
The Quick Sleeper trait means colonists will need only half the sleep time before they’re up and ready to face the day. This is one of the best traits, as it means your colonists can focus on working for longer and get more things done.
you’re able to control how much your colonists sleep using the schedule page, which you can access from the hotbar at the bottom.
