The '''detoxifier lung''' is an [[artificial body part]] added by the [[Biotech DLC]] that replaces a human [[lung]] and provides enhanced [[breathing]] and [[toxic environment resistance]].

== Acquisition ==
Detoxifier lungs can be crafted at a [[{{P|Production Facility 1}}]] once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. They require {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}.

They can also be [[Trade|bought]] from exotic traders, [[Empire]] traders, and at [[Outlander]] [[faction base]]s.

== Summary ==
=== Body part ===
A detoxifier lung replaces the user's organic [[lung]]. The detoxifier lung has a part efficiency of 110%. This not only fully replaces the functionality of a normal lung - when coupled with the lung body part having a [[Breathing]] importance of 50%, it results in an increase in breathing of {{+|5%}} over natural per lung replaced. Breathing, in turn, improves [[Moving]] by {{+|1%}} and Rest Rate Multiplier by {{+|1%}}, increasing the rate at which the pawn sleeps.{{Check Tag|Verify|Based on code + math, needs to be verified in-game}} 

By installing a detoxifier lung, the pawn's natural [[lung]], if perfectly healthy, is harvested without a penalty. 

=== Other effects ===
A detoxifier lung increases [[Toxic Environment Resistance]] by {{+|60%}}. Replacing both lungs stacks to the maximum of {{+|100%}} resistance. This reduces the amount of [[toxic buildup]] from [[toxic fallout]], [[tox gas]] and [[pollution]] by 60%. Note that it does not prevent the other effects of tox gas. Detoxifier lungs are also fully immune to [[rot stink]], [[acidic smog]], [[asthma]], and [[lung rot]], and will cure the latter two aliments in that lung.

=== Installation ===
Installing the part requires {{Ticks|2500}} of work, 2x medicine of [[Herbal medicine|herbal]] quality or better, and a [[Skills#Medical|Medical skill]] of 5.

Removing the part requires {{ticks|2000}} of work, 1x medicine of [[Herbal medicine|herbal]] quality or better, and has no [[Skills#Medical|Medical skill]] requirements.

If the operation fails, the part will be destroyed.

== Analysis ==
A form of resistance against [[tox gas]] is very helpful when fighting against [[Pirates#Waster pirates|waster pirates]].  Tox gas quickly causes toxic buildup, which, in practice, will force you to reposition tox-vulnerable colonists outside their usual [[cover]]. Gas is especially deadly when the pirates end up [[drop pod]]ding inside your base, because gas quickly spreads indoors. However, bionic parts are expensive to create. If a lung isn't missing, then creating a detox lung should be weighed against creating a more generally useful part (like a [[bionic arm]] or [[bionic leg]]), or the cheaper [[detoxifier kidney]]. 

In the mean time, [[face mask]]s are incredibly cheap to make and provide {{+|50%}} toxic environmental resistance, almost as much as a kidney. These are usually sufficient against toxic fallout and rot stink, and somewhat alleviate the threat of tox gas. As face masks only cover the jaw, they can be worn alongside [[simple helmet]]s or [[flak helmet]]s freely (but not any [[power armor]] helmet). Detox lungs stack additively with face masks; 1 lung and a mask will provide total environmental immunity. 

As an alternative, [[gene]]s can be used to provide toxic resistance or full immunity. Like all genes, they come at a [[metabolic efficiency|metabolic cost]].

Detoxifier lungs are craftable, meaning they can replace a destroyed lung when there are no [[prisoner]]s to harvest from, or if your colony's [[ideoligion]]{{IdeologyIcon}} prevents organ harvesting.

=== Comparisons ===
==== To detoxifier kidneys ====
The primary difference between detoxifier lungs and [[detoxifier kidney]] is that the lung provides [[Toxic Environment Resistance]], while the kidney provides [[Toxic Resistance]]. The kidney will not protect from [[rot stink]]. However, it does protect against direct toxic attacks. These include: a [[cobra]] or [[waste rat]]'s bite, the [[apocriton]]'s [[Toxic needle gun|gun]], or Royalty's [[venom fangs|venom-based]] [[venom talon|implants]]{{RoyaltyIcon}}. Note: toxic attacks are relatively rare. 

Detoxifier lungs stack additively with other sources of Toxic Environment Resistance. A single lung and a [[face mask]] will provide 100% protection against inhaled toxins, but a kidney and a face mask stack multiplicatively and provide only 75% protection against inhaled toxic buildup. 

If on a budget and no other items are to be used, such as when full face helmets are required, then a single detoxifier lung provides {{+|10%}} more resistance than a single detoxifier kidney.    

As a lung, detox lungs will increase movement and rest. In general, this is generally more useful than [[Immunity Gain Speed]], especially by the time you create bionic parts. However, both boosts are fairly small. Detox kidneys will also prevent installation of the [[immunoenhancer]] {{RoyaltyIcon}} in that kidney; this implant increases IGS by a greater amount. But, as artificial parts, lungs will prevent [[asthma]] and lung rot in that lung. Kidneys prevent [[chemical damage]] from taking too many [[psychite]] drugs.

Finally, detox kidneys require {{Required Resources|Detoxifier kidney}}, as opposed to {{Required Resources}} of the lung. The lung is nearly twice as expensive.

==== To antitoxic genes ====
There are 3 default [[xenotype]]s that come with anti-toxic genes:
* [[File:Hussar.png|20px|link=Hussars]] [[Hussars]] - [[File:Gene_PartialPollutionResistance.png|20px|link=Genes#Partial antitoxic lungs|Partial antitoxic lungs]] [[Genes#Partial antitoxic lungs|Partial antitoxic lungs]] - {{+|50%}} Toxic Environment Resistance - {{--|1}} [[Metabolic efficiency]]
* [[File:Waster.png|20px|link=Wasters]] [[Wasters]] - [[File:Gene_TotalPollutionResistance.png|20px|link=Genes#Total antitoxic lungs|Total antitoxic lungs]] [[Genes#Total antitoxic lungs|Total antitoxic lungs]] - {{+|100%}} Toxic Environment Resistance - {{--|3}} [[Metabolic efficiency]]
* [[File:Sanguophage.png|20px|link=Sanguophage]] [[Sanguophage]] - [[File:Gene_TotalToxicityResistance.png|20px|link=Genes#Tox immunity|Tox immunity]] [[Genes#Tox immunity|Tox immunity]] - {{+|100%}} [[Toxic Resistance]] - {{--|4}} [[Metabolic efficiency]]
Partial antitoxic lungs will stack with other sources of Toxic ''Enviroment'' Resistance additively. Having this gene and a [[face mask]], or a gene and a lung, renders full environmental immunity. In addition, the [[Genes#Tox resistance|Tox resistance]] gene gives {{+|50%}} Toxic Resistance, which stacks with the detoxifier ''kidney'' additively.

Not all potential colonists will be of these xenotypes; you'll need a xenogerm to implant. There are 2 costs of genetic modding. One is metabolic efficiency; you'll either have to compensate with a negative gene, or face up to a +75% increased hunger rate. The second is actually obtaining the relevant [[genepack]]. A [[gene extractor]] will extract random genes from a pawn, meaning there's no guarantee you'll get these genes. Traders can sell any of the 4 toxic genes, but they have, again, an entirely random selection.

Once you have a suitable gene combination (Total antitoxic lungs + [[Genes#Drugs|Psychite dependency]], for instance), then installing the [[xenogerm]] from there only requires {{icon small|herbal medicine}} 4 [[herbal medicine]] and a few hours of work. Genepacks are not consumed, so one set of genes can be applied to all your colonists. This is much cheaper than installing detoxifier lungs or kidneys into each colonist. Also note that xenogerm implantation will '''fully replace''' any xenogenes a pawn has. Installing a xenogerm into your [[genies]], [[highmates]], [[hussars]], or [[sanguophages]] will completely overwrite their genes.

When starting with a player-created [[xenotype]], you can begin with whatever genes you wish. The only cost, then, is the decreased metabolic efficiency. And if you recruit a [[waster]] or obtain a [[sanguophage]] later on, then they will start toxic immune - no need for a lung. (Sanguophages are immune to rot stink due to the [[Genes#Perfect immunity|Perfect immunity]] gene).
