Healer mech serum - RimWorld Wiki (2024)

The healer mech serum is an item that can heal almost every health condition.

Acquisition[edit]

Healer mech serums cannot be crafted, nor can it be bought from traders. Instead they can only be found in ancient shrines or acquired as a reward for performing quests. Note that quest rewards are selected with a weighted random generator, so there is no way to guarantee access to a serum in a given play-through. Anecdotally, it is often reported that the increased number of reward options added by the DLC dilute the reward pool with more options.

Summary[edit]

Healer mech serums will heal a single health condition. It removes the most "severe" health problem, in a specific order. If there are no healable conditions, the serum will still be consumed. Pawns can be directed to use a serum on themselves or others.

The serum will heal these conditions in the following order:

1. Missing limbs, hands, and feet (Not fingers/ toes)
   • Legs
   • Shoulders/arms
   • Spine
2. Whole body ailments
   • Toxic buildup
   • Diseases, in order of severity
   • Blood loss
   • Heatstroke
   • Hypothermia
   • Frail
   • Sterilized
3. Brain ailments
   • Resurrection psychosis
   • Trauma savant
   • Alzheimer's
   • Dementia
   • Crumbling mind, so long as it has not progressed to crumbled mind.
4. Scars on the brain
5. Missing organs
   • Lungs
   • Kidneys
   • Facial parts
   • Fingers/ toes
6. Ailments in other parts
   • For example: Carcinoma, Cataract, Bad back
7. Drug addiction
8. Scars on other parts
9. Injuries

Organs that occur in pairs (kidneys, eyes, ears) will always be healed in pairs (e.g. the serum would cure a cataract in both eyes, not just one). Replacements, however, occur individually.

Restrictions[edit]

Below are the conditions which the serum cannot treat:

• Luciferium need
• Drug tolerances
• Anesthetic
• Fertility Procedures: Tubal Ligation, Implanted IUD, Vasectomy
• Crumbled mind

To regrow a missing body part, the artificial part has to be removed first (by surgery) before the serum is applied.

Analysis[edit]

Firstly, don't expect to find more than a handful of these serums during a playthrough, if even that many. Use it wisely: most missing limbs and failed organs can be replaced, either with artificial or natural parts. Serums should be saved for situations where all other treatments fail, such as brain damage, or when a pawn would certainly die otherwise.

Conditions are treated in a strict order. An infection (Major, developed immunity) will be cured over Alzheimer's, even though the former is virtually harmless. Blood loss and toxic buildup are cured before scars are. Do not apply the serum unless absolutely certain it will heal the correct condition.

Uses[edit]

• Great for colonists with brain damage, dementia and frailty. These can be quite crippling, and most other ways to treat them come with significant downsides (see below).
• Repair shattered spines or pelvises to allow colonists to function again (the former can however also be fixed with a bionic spine).
• Immediately end a colonist's catatonic break, at quite a cost. Do so when the colonist is absolutely vital to your colony's operations -- this should be a very rare occasion.
• This is the only option to fix certain Social penalties in the base game, such as the Disfigured debuff from a missing nose.
  • A missing nose can be fixed with the aesthetic nose or biosculpter pod, but both require their respective DLC installed.

Alternatives[edit]

Many permanent conditions like Dementia or Alzheimer's can be cured with other methods, which all have some other form of cost. For a full comparison of what can and can't be healed by these methods, see the Healing method table below.

• Killing the pawn and applying a resurrector mech serum, an item of the same rarity as the healer mech serum. It can also cause adverse side-effects, including the fatal psychosis (which ironically, requires a healer mech serum to treat).
• Luciferium, which will cause immediate hard dependence on the drug. It requires constant intake; while it does provide significant stat buffs, luciferium is expensive, and withdrawal is fatal.
• Biosculpter pods. The Bioregeneration cycle can heal many conditions (less than lucifierium), which costs 2 glitterworld medicine, up to 25 days in a clean room to complete, and dedicated research.
• Scarless gene. This either requires the scarless genepack and an archite capsule, or has the price of becoming a sanguophage. It can also be obtained from game start.

Healing method table

Some injuries and health conditions will not naturally heal or cannot be immediately cured by treatment. In these cases, transplantation, artificial body parts, healer mech sera, luciferium or biosculpter pods may help, but each has its own unique list of what it can and cannot cure.

^Both Heals both relevant organs if condition is present in both.

^One Heals only one organ, even if condition is present in both.

^Prev This option prevents the acquisition of new cases of this condition, independent of whether or not it cures existing cases.

^IGS While this option does not outright cure these diseases, the increase to Immunity Gain Speed can hasten their healing and/or help prevent fatal cases.

^Note 1 This condition can only be cured until it reaches its final stage. Once it has, it becomes permanently incurable.
