RimWorld is a game based on the story of its characters, either player-managed colonists or AI-controlled wanderers and raiders.

Each character has two sets of attributes, a basic set of skills and a two-part backstory (childhood and adulthood) that affect the starting skills and (in)abilities of the characters.

See also Colonist.

Every character in RimWorld has a set of skills; these skills govern their effectiveness in the relevant tasks. A character may be unable to undertake certain work types due to backstory elements, and as such, the relevant skills will be disabled entirely, and show " - " under skills on the character tab. Experience points are gained by performing a relevant task or may be boosted by using a neurotrainer.


Experience counts assume "Interested", i.e. neutral, experience gain.


Colonists have the ability to tame and handle a variety of wild animals. These animals can then be trained in four basic categories:

Obedience.png Obedience: (Training intelligence required: Simple) - An animal trained in obedience follows its master and will attack nearby aggressors. An animal's master is listed on the Training tab and on the Animals menu. The assigned master can be changed to another colonist with sufficient animal skill for that animal. Multiple animals may be assigned to a single master. Note that assigning an animal to the pawn it is bonded with will give that pawn a permanent +5 moodlet, and if a bonded animal is not assigned to its bonded pawn, that pawn gets a permanent -3 moodlet. This effect does not stack with multiple bonded animals, however one pawn can have both the positive and negative moodlets from two bonded animals.

Release.png Release: (Training intelligence required: Intermediate) - When animals are released by their master, using the 'release animals' command, they may leave their master's immediate area to attack enemies. When the 'release animals' command is turned off, animals will guard their master and only attack enemies nearby.

Rescue.png Rescue: (Training intelligence required: Advanced) - Animals trained in rescue will rescue its master as well as nearby colonists. Only species of sufficient size can rescue.

Haul animal.png Haul: (Training intelligence required: Advanced) - Animals trained in hauling will haul just as colonists do, although each species has a specific carrying capacity according to its size. Only species of sufficient size can haul, but the size required is less than it is for rescuing, meaning some animals can haul items but cannot rescue. Animals will perform hauling intermittently.


Sculptures add beauty to any space that they occupy once they are installed.

They come in 3 different sizes.

Sculptures are created at the sculptor's table and they have a quality when they are made. The Artists skill is a driving factor in the quality of the sculpture.

On the small, large and grand sculpture pages are tables detailing statistics on that sculpture type.


The construction skill affects how long a colonist takes to complete a construction or repair task. It also affects the quality outcome of some items such as beds, chairs, tables, etc.

Each point increases speed by 15%.

Experience is gained each tick spent working on a construction project. At 100% work speed this seems to translate to roughly 82 experience per point of 'work required' for a construction job. At 200% work speed, disregarding colonist passions, each unit of 'work required' would reward only 41 experience.


The cooking skill affects how long it takes to cook meals and butcher dead creatures. It also affects Butchery Speed and Butchery Efficiency, how much meat is produced when butchering.

Cooking and butchering increase cooking skill.

A cooking skill of at least 6 is required to make a fine meal.
A cooking skill of at least 10 is required to make a lavish meal.

Each point decreases cooking time by 11%

Each point decreases butchering time by 10%

Each point increases meat amount by 2.5%

Project Experience Given Per Task
Simple Meal 60
Fine Meal 110
Lavish meal 160
Pemmican 80


The crafting skill affects the smith, tailor and craft work types.

The Crafter's skill is a driving factor in the quality of crafted clothing and neolithic weapons.

The crafting skill determines the time it takes for a colonist to cut stone, extract metal from slag, and disassemble mechanoids. It also determines the amount of resources produced.

Each point decreases crafting time by 10%

Each point increases the resource yield by 2.5%

Each stone cut into blocks provides 100 experience.


The growing skill affects how fast a colonists sows and harvests growing zones, hydroponics and flower pots.

Each point increases speed by 12%.

Project Experience Given Per Task
Harvesting 50

Some plants require a minimum growing skill in order to plant them:

Main article: Doctoring

The Medicine Skill is the driving factor in determining base medical treatment quality, surgery success chance, and the speed at which medical operations are performed. People with lower medicine skill are more likely to give Poor quality treatment, meaning that poorly treated open wounds are still susceptible to infection and also have a chance to leave a scar - which permanently lowers the health of the affected body part, along with giving a constant amount of pain. Certain scars can be painful enough that they give more than 10% pain, meaning that the consciousness of the affected individual is permanently weakened, which affects their performance in all aspects from work to shooting.

Doctors which are either physically hindered (e.g. missing an arm) or sick (e.g. food poisoning) and/or have low medicine skill are significantly more likely to fail at surgery. The severity of an operational failure varies from only a minor failure; where the part being installed (if installing) may still be re-usable and only do moderate damage to the patient. However, there can also be a catastrophic failure where the part being installed will be destroyed, and there will be surgical cuts doing severe damage, and possibly even being fatal.

Medicine can be trained very quickly by performing euthanasia on fast-breeding animals such as chickens.


The melee skill determines a characters' chance to land a hit in melee.


The mining skill determines how long it takes for a colonist to mine out each rock.

Each point increases speed by 15%.


This skill affects the speed at which research is completed.

Each point increases speed by 15%

Each point in research provides you with 1 experience.


The shooting skill affects a characters' accuracy with a ranged weapon. The table below shows post-processed shooting accuracy per tile of distance for each skill level and trait combination, assuming the pawn is healthy:

Skill Level Standard Careful Shooter Trigger-Happy Skill Level Standard Careful Shooter Trigger-Happy
0 86% 91.833% 72.667% - - - -

10 97% 99.17% 85.467% 20 97.85% 99.196% 85.92%


The social skill affects the impact of social interactions on other characters' mood, the impact of gifts on faction relations, the recruitment chance for prisoners and trader prices. A small amount of experience is gained every time two colonists have a social interaction with each other. Characters have a talking stat that somehow interacts with this skill

Each point increases social interaction impact by 10%

Each point increases gift impact by 5%

Each point increases recruitment chance by 5%

Each point makes trade prices 0.5% better


As well as their skill levels, each character can have a level of passion for each skill. The level of passion determines the rate at which the character will develop that skill. A characters' passion level for a particular skill is depicted by a flame icon beside the skill on the character tab. The levels of passion are:

As of Alpha 14 (July 15th, 2016), once colonists have learned a certain (4000) amount in a day, they’ll learn at a much-reduced rate(20%) until the next day.


Skills with no flames. Characters with no passion for a skill only gain experience toward that skill at 33% of the standard rate.


Skills with one flame. Characters that are interested in a skill will gain experience at the standard rate of 100%.


Skills with two flames. Characters with a burning passion for a skill will gain experience at 150% of the standard rate.

Experience Table

Note that level decay begins at level 10 (Expert), at which point colonists will be constantly losing experience at an increasing rate the higher the skill is. There is no level 21, as the max experience in the game is capped at 230999, 1 exp short of leveling up.
