Difference between revisions of "Injury"

Injuries are physical damage to a living being. Humanoids, animals, and mechanoids can sustain injuries from many sources, which each have their own Damage Type.

Injury types

Main article: Health Difficulties

Different weapons cause different types of injuries. For example, a mace will crush, a longsword will cut, and fire will burn. The type of injury impacts the amount of pain it causes, the rate of bleeding, and the chance of infection

Summary

Injuries reduce a body part's health, its efficiency, and causes pain to the pawn.

Damage

Every body part has a health value, which is lowered every time it takes damage. When it reaches 0, the part is completely destroyed.

Damage also lowers a body part's efficiency, proportional to its health remaining. For example, if a arm has 15/30 health, then that arm performs 50% worse. As each arm is responsible for 50% Manipulation, this results in the pawn having -25% Manipulation until the injury is healed. Some parts, like the torso, are not responsible for any pawn stat, but still take damage and cause pain.

Pain

Main article: Pain

The greater the damage, the greater the pain. Pain is equal to pain = (damage / healthscale) * damagetype, where most injuries have a damagetype of 1.25. For humans, health scale = 1, so it has no impact for their pain. Pain reduces Consciousness directly, which reduces most pawn capabilities. It also gives a rapidly increasing mood penalty, unless the pawn is a masochist or follows an ideoligion with the Pain is Virtue meme.

Excessive pain causes pain shock, the most common way to down pawns in combat, which prevents them from fighting. Most pawns have a Pain Shock Threshold of 80%. Note that enemies have a chance to immediately die when downed from pain shock, but not from other means, like blood loss or heat stroke.

Mechanoids are machines, and are immune to pain. In humans, pain can be completely eliminated with a painstopper, or reduced for a short time with go-juice or the Painblock psycast.

Bleeding

Bleeding is a common occurance from certain damage types. While an injury is bleeding, pawns will gain blood loss, scaling with the wound and amount of wounds. Total blood loss is listed under whole body, with a tooltip showing the percent. If blood loss reaches 100%, the pawn will die. Bleeding pawns will also leave blood on the ground, making the area dirty.

Bleeding always stops immediately with tending, regardless of the tend quality or medicine used. However, higher quality medicine can cover more wounds at once, which can stop a pawn from bleeding out faster. Injuries will also heal on their own, though a lost limb will always continue to bleed until tended to.

The coagulator implant halves the rate of blood loss, while the Superclotting gene rapidly stops bleeding. The ability added by the Coagulate gene also immediately tends all wounds on the target pawn, instantly stopping bleeding.

Infections can occur whenever a pawn is hurt by a bite, burn, frostbite, or any damage type that causes bleeding. A completely destroyed body part won't cause infection. Once a pawn recieves these injuries, the game starts a random timer between 15,000 ticks (4.17 mins) to 45,000 ticks (12.5 mins), per injury before checking for infection. The chance of infection depends on:

Damage type. Bite, burn or frostbite wounds have a 25% chance, other bleeding wounds have a 10% to infect.
Tend quality. The multipler is 85% at 0% tend quality, linearly decreasing to 5% at 100% tend quality.
Location. The higher the Cleanliness, the lower the chance for infection (50% at 0 Cleanliness).

Animals are 20% as likely to recieve an infection. Mechanoids can't get diseases.

Scarring

Scars are lasting markers of injuries. They permanently lower the health of the scarred body part, reducing their efficiency. They also cause a character a small amount of pain, even if the relevant body part is otherwise healed. The chance of scarring depends on damage type and the part being damaged. Pawns can also start with scars on them. The eyes are particularly vulnerable to scars, while brain damage will always be permanent.

Scars can be healed by a limited number of ways. Artificial body parts never scar, and replacing an organic part will cure any scars. Luciferium and the Scarless gene heal 1 scar every 15-30 days. A biosculpter pod can do Bioregeneration, which costs 2 glitterworld medicine and takes time to complete. A healer mech serum can heal scars, but is very rare.

Healing

Injured colonists will recover from their wounds over time. Tending to a wound and resting in bed speeds up recovery.

Healing Rate

Every 600 ticks (10 secs), heal rate × 0.01 points of damage are healed from a randomly selected (non-permanent) wound, or an average recovery of heal rate points of damage per in-game day (60,000 ticks). This healing reduces the severity of the injury, until the body part is fully recovered.

The exact heal rate is determined by adding up three factors:

Default healing rate: All pawns have a base heal rate of 8.
Is the pawn lying down or in a bed?: +4 for resting on a sleeping spot or the ground, +8 for resting on a bed / bedroll, and +14 for resting on a hospital bed.
Is the wound tended?: +4 for 0% tend quality and +0.08 per percentage of quality, up to +12 at 100% tend quality.

Immunity Gain Speed has no impact on injury recovery; it only impacts diseases.

Example

To put this in perspective, consider a colonist who has taken 20hp of damage to various body parts, given different recovery scenarios:

Do nothing: With no tending or rest, they get the base heal rate of 8, so it will take (20 × 60,000) / 8 = 150,000 ticks (2.5 in-game days) to fully heal.
Basic tend and resting: With a 40% tend quality (+7.2) and rest in a non-hospital bed (+8), they'll have a heal rate of 8 + 7.2 + 8 = 23.2, so it will take 51,724 ticks to heal (approximately 21 in-game hours)
Best quality care: With 100% tend quality (+12) and rest in a hospital bed (+14), they'll have a heal rate of 8 + 12 + 14 = 34, so it will take 35,294 ticks to heal (approximately 14 hours in game)

Medicine

Medicine does not directly cause healing, but it increases the average tend quality. Whenever a wound is tended, the quality is multiplied by the medicine given:

Medicine	Potency
None	0.30
Herbal medicine	0.60
Medicine	1.00
Glitterworld medicine	1.60

Each type of medicine has a cap on their tend quality; herbal medicine can reach a quality up to 70% in a regular bed, for instance.^[Verify]

While bleeding wounds can be stopped by any quaity of treatment, medicine can treat multiple small wounds in a single "batch" of tending. For patients with many bleeding wounds, the difference can easily be life or death.

Medicine is also useful for treating disease, where tend quality is more impactful, and performing surgery, which is boosted greatly by medicine.

Disfigured

Damage to the nose caused Hairy to become disfigured

Disfigurement is caused by damage or destruction to the nose, eyes, ears, or jaw. It adds the "Disfigured −15" opinion modifier. Disfigurement can be treated by healing/replacing the injured/destroyed body part.

While disfigurement does not have a direct impact on a pawn's beauty, it does disable the positive opinion for positive beauty, while stacking with negative beauty.

Similarly to beauty modifiers, ascetic, kind, and blind pawns do not gain nor lose any opinion based on disfigurement. Pawns with the Blindsight ideoligion instead revere pawns with destroyed eyes.

Trauma Savant

Being shot in the brain can cause the trauma savant condition.

A pawn may become a trauma savant upon taking and surviving an injury to the Brain. Certain capabilities will rise and some will fall.

Trauma Savant removes all ability to socialise, trade, or recruit by capping the pawn's capacity of Talking and Hearing at 0%; In exchange, the pawn's Manipulation is increased by 50%, and they regain full brain function (meaning Consciousness and other functions will be normal) - this is great for doctors, crafters, general workers, and melee combat pawns (all of which rely on Manipulation and are not capped on its usage), but it'll make affected wardens or traders completely useless at that aspect.

There is a 12% chance of any pawn becoming a trauma savant upon receiving brain damage. It does not have to be a humanlike, and can sometimes be seen applied on animals.

While Trauma Savant can be cured, it is difficult and expensive; it is usually better to take advantage of the increased manipulation. To cure Trauma Savant, you will need a Healer mech serum; however this will heal the brain scarring first, so you have to either use multiple Healer mech serums or first apply Luciferium which will eventually heal all the scarring, at which point you can apply the Healer mech serum when Trauma Savant is the only health negative left.

Trivia

Brain injuries in Rimworld cause large amounts of pain (20% or higher for a 5 hp wound), which can render a pawn permanently comatose in certain cases. This is a result of the reduction in Consciousness from the pain being added on top of the direct reduction in Consciousness from the brain injury itself due to the reduced part efficiency. However, in real life the human brain has no pain receptors. Despite their perceived location, headaches are usually caused by receptors triggering elsewhere in the head or neck, not by receptors in the brain. Certain types of headaches are due to irritation or swelling in the meninges, which is the membrane enveloping the brain and which does have pain receptors.

+==Summary==
-{{main|Pain}}
+Injuries reduce a body part's health, its efficiency, and causes pain to the pawn.
-Injuries cause pain to a pawn, and excessive pain can cause a pawn to be downed from pain shock. Enemies have a chance to [[Death|die]] instantly after being downed from pain, which can be adjusted in the difficulty settings. This can be particularly annoying when trying to capture a specific pawn for recruitment. Downing from other sources such as [[hypothermia]], [[heatstroke]], or [[toxic buildup]] do not kill instantly.
-Most pawns go into pain shock once their pain exceeds 80% except for [[Traits|wimps]] who are downed at 20% pain. Certain drugs such as [[go-juice]] and [[smokeleaf]] inhibit pain, and the [[painstopper]] implant removes it altogether. This does not come without a downside, however. Pain has a purpose. It tells the body when it is injured, and without pain or player intervention, pawns will continue to fight until they either win, die or, less likely, receive a crippling injury to the legs, pelvis or spine.
+===Damage===
+Every body part has a health value, which is lowered every time it takes damage. When it reaches 0, the part is completely destroyed.
-== Bleeding ==
+Damage also lowers a body part's efficiency, proportional to its health remaining. For example, if a arm has 15/30 health, then that arm performs 50% worse. As each arm is responsible for 50% [[Manipulation]], this results in the pawn having -25% Manipulation until the injury is healed. Some parts, like the torso, are not responsible for any pawn [[stat]], but still take damage and cause pain.
-Bleeding is a common side effect of certain types of injuries which leads to [[Ailments#Blood_loss|blood loss]]. Bleeding wounds are identified on the health tab by a blood icon next to an injury, and a tooltip shows the bleeding rate. Total blood loss is listed under whole body with a tooltip showing the percent. Overall bleeding rate is shown at the bottom. Bleeding pawns will leave [[Filth#Blood|blood]] on the ground, making the area [[cleanliness|dirty]].
-Injuries do not immediately lose any quantity of blood, instead only draining over time from open wounds. Pawns are unable to recover from [[Ailments#Blood_loss|blood loss]] until all wounds are sealed. Bleeding always stops immediately with tending, regardless of the tend quality or medicine used. However, higher quality medicine can cover more wounds at once, which can stop a pawn from bleeding out faster.
+===Pain===
+{{Main|Pain}}
+The greater the damage, the greater the [[pain]]. Pain is equal to <code>pain = (damage / healthscale) * [[Health Difficulties|damagetype]]</code>, where most injuries have a damagetype of 1.25. For humans, health scale = 1, so it has no impact for their pain. Pain reduces [[Consciousness]] directly, which reduces most pawn capabilities. It also gives a rapidly increasing [[mood]] penalty, unless the pawn is a [[masochist]] or follows an [[ideoligion]]{{IdeologyIcon}} with the [[Ideoligion#Memes|Pain is Virtue]] meme.
-Smaller cuts are able to seal thelselves over time, however larger injuries such as missing limbs will never stop bleeding without tending.
+Excessive pain causes [[pain shock]], the most common way to [[downed|down]] pawns in combat, which prevents them from fighting. Most pawns have a [[Pain Shock Threshold]] of 80%. Note that enemies have a chance to immediately die when downed from pain shock, but not from other means, like [[blood loss]] or [[heat stroke]].
-Have a [[coagulator]] {{RoyaltyIcon}} implant installed halves the rate of blood loss, while the [[Genes#Superclotting|Superclotting gene]] {{BiotechIcon}} rapidly stops bleeding.

Total blood loss is listed under whole body, with a tooltip showing the percent. If blood loss reaches 100%, the pawn will die. Bleeding pawns will also leave [[Filth#Blood|blood]] on the ground, making the area [[cleanliness|dirty]].
-Every couple of minutes in game, a random injury will be healed by a small amount.
-This healing reduces the severity of the injury, and when the severity of the injury reaches zero the injury is fully healed.
-Every {{ticks|600}}, <font color="#390">'''''heal rate'' &times; 0.01'''</font> points of damage are healed from a randomly selected (non-permanent) wound.  This is equivalent to healing ''heal rate'' points of damage per in-game day ([[Time|60,000 ticks]]), or healing an average of 1 point of damage every <font color="#390">'''60,000 / heal rate'''</font> ticks.
+Bleeding always stops immediately with tending, regardless of the tend quality or medicine used. However, higher quality medicine can cover more wounds at once, which can stop a pawn from bleeding out faster.

+[[Infection]]s can occur whenever a pawn is hurt by a bite, burn, frostbite, or any damage type that causes bleeding. A completely destroyed body part won't cause infection. Once a pawn recieves these injuries, the game starts a random timer between {{ticks|15000}} to {{ticks|45000}}, per injury before checking for infection. The chance of infection depends on:

+*Tend quality. The multipler is 85% at 0% tend quality, linearly decreasing to 5% at 100% tend quality.
+*Location. The higher the [[Cleanliness]], the lower the chance for infection (50% at 0 Cleanliness).
-Note that [[Immunity Gain Speed | immunity gain speed]] has no influence on the recovery rate from injuries -- it only affects recovery from [[disease]] (and vice-versa, the bonuses applied by beds and hospital beds to healing are different from the bonuses they apply to immunity gain speed).
+[[Animal]]s are 20% as likely to recieve an infection. [[Mechanoid]]s can't get diseases.
-=== Medicine ===
+===Scarring===
-Medicine does not ''directly'' cause healing.  Instead, it affects the average [[Doctoring|tend quality]], which is also affected by the bed (or surface) the pawn is resting in and the skill and physical capacities of the doctor.  Each type of medicine ([[Herbal medicine|herbal]], [[Medicine|industrial]], and [[Glitterworld medicine|glitterworld]]) has a medical potency value, which is a direct multiplier on the average treatment quality, ranging from 0.3 for no medicine at all to 1.6 for Glitterworld Medicine.   As the treatment quality is one element of the healing equation, it ''does'' impact the healing process, but only partially.  For example, a colonist resting in a hospital bed with one wound tended at 0% and another at 100% will have a heal rate for the first wound of 26 and for the second wound of 34, which results in only a 24% reduction in the amount of time needed to heal any given amount of damage.
+{{stub|section=1|reason=Scar information}}
+Scars are lasting markers of injuries. They ''permanently'' lower the health of the scarred body part, reducing their efficiency. They also cause a character a small amount of pain, even if the relevant body part is otherwise healed. The chance of scarring depends on damage type and the part being damaged. Pawns can also start with scars on them. The eyes are particularly vulnerable to scars, while brain damage will always be permanent.
-However, medicine is also highly useful during tending, in that a doctor using medicine can often treat multiple small wounds in a single "batch" of tending, but must treat each individually if not using medicine.  For patients with a high bleed rate, the difference can easily be life or death.  As medicine is a valuable commodity in the early to mid game, this generally means you should conserve it and be careful about what you use it on. Large, bleeding cuts should be prioritized, while burns, frostbite, and bites should be tended with medicine next because of the high infection chance (unless the wounded person is almost dead from [[blood loss]], in that case the smaller cuts should be tended with medicine). Bruises and cracks have no infection chance and should be tended with medicine last.  However, note that you cannot select which wound(s) a doctor treats with each tend, so if a colonists has both bleeding or high-infection-risk wounds and bruises, it may still be worth using medicine on the colonist's wounds to ensure the important ones are tended properly.
+Scars can be healed by a limited number of ways. [[Artificial body part]]s never scar, and replacing an organic part will cure any scars. [[Luciferium]] and the ''Scarless'' [[gene]]{{BiotechIcon}} heal 1 scar every 15-30 days. A [[biosculpter pod]]{{IdeologyIcon}} can do Bioregeneration, which costs {{icon small|glitterworld medicine}} 2 [[glitterworld medicine]] and takes time to complete. A [[healer mech serum]] can heal scars, but is very rare.
-Disease tending is also very important.  Most diseases have a certain amount of severity gained per day, and then a certain amount of severity ''lost'' per day when tended.  If severity reaches 100%, the colonist (or animal) dies from the disease.  The severity lost per day when tended is directly multiplied against the tend quality.  Since immunity gain speed is fixed for each specific disease, high tend quality versus low can mean the difference between living and dying to the disease in some cases, especially with older or impaired patients (who have lower immunity case rates).  Other diseases (ex. Muscle Parasites) do not gain severity at all (nor immunity), and instead require a certain ''sum'' of treatment quality across all tends to the illness before they disappear.  Using better-quality medicine gives a substantially higher average tend quality, which can make the diseases disappear substantially quicker.
+==Healing==
+Injured colonists will recover from their wounds over time. [[Doctoring|Tending]] to a wound and resting in bed speeds up recovery.
-Also note that surgery is impossible without medicine, and has a much lower base success chance than the equivalent base treatment quality at most levels of the Medicine skill.  As such, using the best available medicine, as well as the cleanest surgical environment and highest quality surgical bed possible, is very important, often more so than the skill of the surgeon.  For example, the difference between a level 10 surgeon (93% base surgery success chance) and a level 20 surgeon (99%) is only a 6.5% gain in surgical success rate.  The difference between Herbal Medicine (60% potency) and Glitterworld Medicine (160% potency) is a ''167% increase'' in surgical success rate.
+===Healing Rate===
+Every {{ticks|600}}, <font color="#390">'''''heal rate'' &times; 0.01'''</font> points of damage are healed from a randomly selected (non-permanent) wound, or an average recovery of ''heal rate'' points of damage per in-game day ([[Time|60,000 ticks]]). This healing reduces the severity of the injury, until the body part is fully recovered.
-However, note that '''surgery success rate cannot exceed 98%'''.  All doctors, regardless of skill, medicine, and surgical environment, always have at least a 2% chance of failing the surgery.  This means that any combination of doctor skill and capabilities, medicine, and surgical environment that results in a 98% or higher surgical success rate is equivalent, and all additional bonuses are wasted.
+The exact heal rate is determined by adding up three factors:
-* '''Examples''': A legendary hospital bed applies a 1.43 surgery success chance factor, which is a direct multiplier on the surgical success chance.  Assuming a level 10 doctor (93% base success chance) and a neutrally clean room (Cleanliness 0, though you'll generally want to use [[sterile tile]]s in your hospital to improve this), and a normal success chance surgery, the [[Doctoring#Surgery|surgical success chance]] with Herbal Medicine would be 83.78%, with Medicine 139.64%, and Glitterworld Medicine 223.42%.  However, since success chance cannot exceed 98%, both regular Medicine and Glitterworld Medicine are identical, and using the latter is a waste.
+* '''Default healing rate''': All pawns have a base heal rate of <font color="#390">'''8'''</font>.
+* '''Is the pawn lying down or in a bed?''': <font color="#390">'''+4'''</font> for resting on a [[sleeping spot]] or the ground, <font color="#390">'''+8'''</font> for resting on a [[bed]] / [[bedroll]], and <font color="#390">'''+14'''</font> for resting on a [[hospital bed]].
+* '''Is the wound tended?''': <font color="#390">'''+4'''</font> for 0% [[tend quality]] and <font color="#390">'''+0.08'''</font> per percentage of quality, up to <font color="#390">'''+12'''</font> at 100% tend quality.
+[[Immunity Gain Speed]] has no impact on injury recovery; it only impacts [[disease]]s.
-: The same surgery performed by the same doctor in a normal bed (1.0 surgical success chance factor) in dirty room (Cleanliness -0.55, resulting in a 1.0 cleanliness surgical success chance factor) would have a 55.8% chance, 93.0% chance, and 148.8% chance of success, using Herbal Medicine, regular Medicine, and Glitterworld Medicine, respectively.  In this case, using Glitterworld Medicine instead of regular Medicine reduces the failure chance of the surgery by 71%!
+===Example===
+To put this in perspective, consider a colonist who has taken 20hp of damage to various body parts, given different recovery scenarios:
-All surgeries in the base game have a 1.0 or higher multiplier to surgical success rate, though certain surgeries have differing rates of death on failure (ex. removing a Carcinoma has a 25% chance of death on failure).  Even aside from the direct death on failure rate, the damage dealt by a surgical failure can completely destroy a body part or organ, which may also result in the colonist's death.  Certain mods add surgeries with lower chance of success, which may justify using stronger medicine than would otherwise be required.
+* '''Do nothing''': With no tending or rest, they get the base heal rate of <font color="#390">'''8'''</font>, so it will take <font color="#390">(20 &times; 60,000) / 8 = 150,000</font> ticks (2.5 in-game days) to fully heal.
+* '''Basic tend and resting''': With a 40% tend quality (<font color="#390">'''+7.2'''</font>) and rest in a non-hospital bed (<font color="#390">'''+8'''</font>), they'll have a heal rate of <font color="#390">8 + 7.2 + 8 = '''23.2'''</font>, so it will take 51,724 ticks to heal (approximately 21 in-game hours)
-The net result is that using higher-end medicine for surgeries is mostly only worthwhile in lower-quality surgical environments (less cleanliness, lower quality hospital beds, lower skilled doctors).  Beyond that point, higher-end medicine is more useful for its improved tend quality than its surgical success benefits.
+* '''Best quality care''': With 100% tend quality (<font color="#390">'''+12'''</font>) and rest in a hospital bed (<font color="#390">'''+14'''</font>), they'll have a heal rate of <font color="#390">8 + 12 + 14 = '''34'''</font>, so it will take 35,294 ticks to heal (approximately 14 hours in game)
-==Scarring==
-Scars are permanent markers of [[#Injury|injuries]]. They permanently lower the health of the scarred body part, making it easier to damage the affected body part in the future, in addition to reducing the efficiency of that body part proportionally.  Body part efficiency is a factor in pawn [[Capacity|Capacities]].  For example, a scarred neck impairs [[Breathing]], which then reduces the pawn's [[Consciousness]], [[Moving]], and [[Rest Rate Multiplier]].  The reduction in Consciousness further reduces the pawn's Moving, as well as [[Manipulation]], [[Eating]], and [[Talking]] capabilities.
-Scars also cause a character a small amount of pain, even if the relevant body part is fully healed. Pain from scars results in a permanent mood penalty for non-masochistic characters. For a colonist with the [[Traits#Masochist|Masochist trait]], scar pain will provide a continual mood bonus instead of penalty.
-Sometimes colonists are generated with minor scars and old gunshots already in place. Some body parts (eyes and brain) also scar instantly upon injury.
+== Medicine ==
+Medicine does not ''directly'' cause healing, but it increases the average [[tend quality]]. Whenever a wound is tended, the quality is multiplied by the medicine given:
+{| {{#if:{{{1|}}}|{{{1|}}}|class="wikitable"}}

-It is possible to remove the pain from some scars by surgically implanting [[Health#Limb Replacement|artificial replacement]]s.  Artificial body parts will never scar.
+While bleeding wounds can be stopped by any quaity of treatment, medicine can treat multiple small wounds in a single "batch" of tending. For patients with many bleeding wounds, the difference can easily be life or death.
-Scars can be treated by [[luciferium]], however the cost of using it usually outweighs the benefit, unless used on numerous scars, or a permanent brain injury.
+Medicine is also useful for treating [[disease]], where tend quality is more impactful, and performing [[surgery]], which is boosted greatly by medicine.
-Another way to work around scar pain is to implement a [[Painstopper]], preventing all ongoing pain. The downside to this, however, is that should the pawn with an installed Painstopper take serious damage - they won't go down until they either lose a leg (or have it heavily injured), or die. Therefore, you should be extra watchful of their health as to decide whether to withdraw them from a controllable scenario (i.e. combat), as to prevent them from losing their life.

+Disfigurement is caused by damage or destruction to the nose, eyes, ears, or jaw. It adds the "Disfigured {{--|15}}" opinion modifier. Disfigurement can be treated by healing/replacing the injured/destroyed body part.
-While disfigurement does nothing to directly affect the [[Beauty (Pawn)|beauty]] of a pawn it does however disable the positive opinion added by positive beauty while stacking with negative beauty, possibly netting a -55 opinion for the affected pawn.
-Similarly to beauty modifiers, [[Traits#ascetic|ascetic]], [[Traits#kind|kind]], and blind pawns do not gain nor lose any opinion based on disfigurement. Nor will pawns with the [[Blindsight]] ideoligion{{IdeologyIcon}}, with regards to damage/removal of the eyes.{{Check Tag|Verify??| Removal of the eyes has a positive opinion effect on blindsight pawns but damage to the eyes, without destruction, is unknown to cause the disfigured status}}
