The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.  The liver accounts for up to 100% of a person's [[blood filtration]] along with the kidneys, and 50% of a person's [[metabolism]]. Destruction of the liver is instantly fatal.

==Analysis==

== Analysis ==
While livers can be harvested from prisoners, guests, and your own colonists, generally it is preferable to harvest from prisoners because removing the liver is fatal. Killing a guest or your own colonist carries a significant mood penalty.
+
Harvesting from a guest will inflict massive [[goodwill]] penalties, and harvesting from a colonist will bring even more [[mood]] penalties, so simply steal organs from a prisoner. If you want a colonist dead, it's best to imprison them first.
  
There are two primary reasons to harvest an organ - trade and transplantation.
+
Total destruction of the liver is instantly fatal, while Consciousness and Immunity Gain Speed are important stats. Thus, you should replace damaged livers on valuable colonists as soon as possible. It must be noted that the Liver is the only organ that has no current bionic replacement.  
 
 
===Transplantation===
 
Livers can be damaged by disease, drugs, or combat. Damage to the Liver reduces Blood Filtration (up to 100% when totally destroyed) and Metabolism (up to 50% when totally destroyed). This has several effects - the first is up to a 10% reduction in [[Consciousness]] which in turn affects almost every task a pawn can perform - making them slightly worse in basically every way.
 
 
 
The second, perhaps more urgent, effect is up to a 50% reduction in [[Immunity Gain Speed]] based on damage to Blood Filtration. This significantly reduces the survivability of infections and common diseases such as the [[Flu]]. If a pawn has an immunity gain speed of 58% or lower because of damage to the liver or kidneys, then the flu will be invariably fatal.
 
 
 
Finally, damage to the Metabolism capacity reduces the [[Rest Rate Multiplier]] which makes a pawn sleep for longer periods to become fully rested.
 
 
 
Total destruction of the liver is instantly fatal. Thus, it is recommended to replace damaged livers on valuable colonists as soon as possible.
 
  
 
===Trade===
 
===Trade===
Each liver is worth 500 silver, and only has a mass of 2. The abundant supply of [[raiders]] means that, if the mood penalty can be withstood, a significant amount of value can be extracted from them without having to keep prisoners and wait for a Slave Trader or Royal Tribute Collector {{RoyaltyIcon}}.
+
Livers are worth {{icon Small|silver||{{Q|Liver|Market Value Base}}}}, worth exactly the same as a [[heart]]. However, the heart can be replaced by the cheaper [[prosthetic heart]]; by installing the prosthetic, you can obtain both the heart and the liver.
 
 
Because removing the Liver is fatal, it's actually suboptimal to remove when the other organs are all okay.  The [[Heart]], [[Lung]]s, and [[Kidney]]s are also options for harvesting. If willing to organ-murder the donor, the optimum is removing:
 
* 1x Lung worth {{icon Small|silver||{{Q|Lung|Market Value Base}}}}
 
* 1x Kidney worth {{icon Small|silver||{{Q|Kidney|Market Value Base}}}}
 
* 1x Heart worth {{icon Small|silver||{{Q|Heart|Market Value Base}}}}
 
For a total of {{icon Small|silver||{{#expr:{{Q|Heart|Market Value Base}} + {{Q|Kidney|Market Value Base}} + {{Q|Lung|Market Value Base}}}}}}.
 
 
 
If the Heart is unavailable you can take the Liver instead which has the same value but weighs twice as much. If that is also unavailable, the second lung and then the second kidney are the optimal options.
 
Removing the heart, liver, second lung or second kidney are all fatal and prevent further harvesting.  
 
  
If unwilling to organ murder the donor, the best option is to harvest

A completely removed heart/liver will kill a pawn. Therefore, it's best to harvest a [[kidney]] and a [[lung]] before taking the liver.

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. Destruction of the liver is instantly fatal.

Acquisition[edit]

Liver items are harvested from live humans through surgery. It must be perfectly healthy in order to obtain the item. This bill requires 1 of any type of medicine to perform. Success chance is dependent on a number of factors, including bed quality, room cleanliness, and doctor skill - specifically the doctor's Medical Surgery Success Chance. Removing the liver will kill the pawn.

Removing the liver from a guest or prisoner will decrease faction goodwill by 160 points, to a cap of -100; -80 for the surgery, and -80 for murder. Other colony members can get potentially tremendous mood penalties, which all stack:

−5 for "Someone's organ harvested" (any organ); −6 if colonist
−6 for "Someone organ-murdered"
−5 for "Witnessed ally's death" (on colonist)
−4 for "Observed corpse"

Pawns with the Bloodlust or Psychopath traits, or those with an Ideoligion with Organ Use: AcceptableContent added by the Ideology DLC are not affected by the harvesting of other people. Other Ideologion precepts may change moodlets for harvest and organ use.

Livers can also be acquired through trading with faction settlements or Exotic Goods traders.

Summary[edit]

Livers are a vital part for humans; losing one will instantly kill them. Livers account for 100% of Blood Filtration and 50% of Digestion.

Blood Filtration has a 0.1x effect on Consciousness, so losing 90% of the liver means -9% Consciousness, which affects a wide variety of stats. It also has a 0.5x effect on Immunity Gain Speed, so a damaged liver will make diseases much more deadly. Finally, damage to Digestion reduces the Rest Rate Multiplier, which makes a pawn sleep for longer periods to become fully rested.

Installation[edit]

Installing the part requires 2,500 ticks (41.67 secs) of work, ?x medicine of ?? quality or better, and a Medical skill of 5.

Removing the part requires 2,000 ticks (33.33 secs) of work, 1x medicine of herbal quality or better, and has no Medical skill requirements.

If the operation fails, the part has a chance[What Chance?] to be destroyed.

Analysis[edit]

Harvesting from a guest will inflict massive goodwill penalties, and harvesting from a colonist will bring even more mood penalties, so simply steal organs from a prisoner. If you want a colonist dead, it's best to imprison them first.

Total destruction of the liver is instantly fatal, while Consciousness and Immunity Gain Speed are important stats. Thus, you should replace damaged livers on valuable colonists as soon as possible. It must be noted that the Liver is the only organ that has no current bionic replacement.

Trade[edit]

Livers are worth Silver 1,200, worth exactly the same as a heart. However, the heart can be replaced by the cheaper prosthetic heart; by installing the prosthetic, you can obtain both the heart and the liver.

A completely removed heart/liver will kill a pawn. Therefore, it's best to harvest a kidney and a lung before taking the liver. This is worth Silver 1,000 + Silver 900 + Silver 1,200 = Silver 3100, before accounting for Market Price or the prosthetic heart. This comes at the usual mood penalties, unless you have a colony filled with Psychopaths or a favorable IdeoligionContent added by the Ideology DLC. A Royal Tribute CollectorContent added by the Royalty DLC will ignore lost organs for sold prisoners, as long as they can walk.

Version history[edit]

  • 0.7.581 - Item form added, and now harvestable.
  • ? (Possibly 1.4) - Market value increased from Silver 500 silver to Silver 1200 silver.
