Kidney

Kidneys are harvestable human organs that contribute to a pawn's blood filtration.

Acquisition[edit]

The kidney item can be harvested from live humans through surgery. The kidney 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. Kidneys can be directly harvested, but installing a detoxifier kidney will also net an organic kidney. Removing both kidneys will kill the pawn.

Removing a kidney from a guest or prisoner will decrease faction goodwill by 80 points, down to the cap of -100. Removing any organ from anyone depresses the "donor" with -30 mood penalty for 7 days and 7 hours. Other colony members can give potentially tremendous mood penalties, which all stack:

−5 for "Someone's organ harvested" (any organ); −6 if colonist harvested

−6 for "Someone organ-murdered" (if fatal)

−5 for "Witnessed ally's death" (if fatal and on colonist / guest)

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

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

Summary[edit]

A human requires 1 kidney to live. Each kidney accounts for 50% of a person's Blood Filtration. Blood Filtration itself affects Consciousness and Immunity Gain Speed; a completely removed kidney reduces Consciousness by 5% and Immunity Gain Speed by 25%. The Consciousness penalty reduces a variety of pawn capabilities.

Carcinoma, one form of tumor cancer, weakens blood filtration. Kidneys can also be damaged from physical injuries or chemically damaged from psychite tolerance.

Installation[edit]

Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal 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]

Immunity Gain Speed is helpful to survive infections and other diseases; if it is 58% or lower, such as from two damaged kidneys, then even the Flu will be invariably fatal. Thus, it is recommended to replace damaged, destroyed or missing kidneys on valuable colonists as soon as possible.

Immunoenhancers can be implanted into pawns with natural kidneys. Each immunoenhancer will grant +8% immunity gain speed to a pawn, which helps recovery from disease.

Harvesting from your own pawns is not recommended, so take from your prisoners or guests. For most pawns, the mood penalty of organ harvest is worth replacing the organ, but this may not apply to more disposable pawns.

Compared to detoxifier kidney[edit]

Detoxifier kidneys are a kidney replacement which can be crafted at a Fabrication bench once the Toxin filtration research project has been completed. Each detoxifier kidney requires 15 Plasteel, 2 Advanced components. Installing a detoxifier kidney replaces the pawn's natural kidney. If the kidney is in perfect condition, it is harvested from the pawn with no negative consequences. Immunoenhancers cannot be installed in a detoxifier kidney.

Detoxifier kidneys have a part efficiency of 110%, grant +50% toxic resistance, and are immune to chemical damage from drugs. Each detoxifier kidney increases blood filtration by +5%, which in turn increases immunity gain speed by +2.5%. Toxic resistance from detoxifier kidneys will stack to a maximum of +100% with 2 installed parts.

Trade[edit]

Each kidney is worth 900 silver. While lungs are worth more than kidneys, you can harvest both a kidney and a lung without killing a pawn. If the mood penalties don't concern you (or don't exist due to Ideoligion), you can harvest 1 kidney, 1 lung, and 1 heart/liver before a pawn dies. This can extract a lot of value, almost certainly more than selling the pawn to a slaver.

You can also harvest a kidney and lung, then donate the prisoner to a royal tribute collector for the same amount of honor as a healthy pawn.
