Prosthetic legs are an artificial body part that replaces a pawn's leg. They are much better than a peg leg or no leg at all, but are inferior to bionic legs, which actually improve the pawn's moving capacity.


Prosthetic legs can be crafted at a Machining table once the Prosthetics research project has been completed. They require Steel 40 Steel, Component 4 Components, 15,000 ticks (4.17 mins) of work, and a Crafting skill of 5.

They can also be purchased from Exotic goods traders.


Prosthetic legs replace the user's entire organic leg. They are universal and can be installed on either the left or right side. The prosthetic leg has a part efficiency of 85%. This partially replaces the functionality of a normal leg - when coupled with the leg body part having a Moving importance of 50%, it results in restoring 42.5% moving per missing leg replaced, or a loss of 7.5% when replacing a healthy leg.

Moving, in turn, affects the following stats: Hunting Stealth, Melee Dodge Chance, Move Speed. This results in a directly proportional change to a pawn's move speed, and a change in melee dodge chance equivalent to losing 1.35 levels of Melee skill per leg replaced. Due to how the stat is fit to a post-process curve, this can result in the melee dodge chance dropping to 0% for pawns with skill under 7, when replacing one leg, or under 10 for both legs.

Each prosthetic leg results in -?% character quality and thus a ?% reduction in the affected individual's pawn value.[Values]

As an artificial part, prosthetic legs will give a mood buff to anyone with the Body modder trait, and a mood penalty to anyone with the Body purist trait.


Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal quality or better, and a Medical skill of 4.

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 will be destroyed.


If a pawn's Moving is lower than 92% due to damage to, or loss of, an organic leg, it is a good idea to replace that leg with a prosthetic leg. Compared to a peg leg, a prosthetic leg gives +12.5% Moving (base +0.575 c/s move speed); upgrading gives a great improvement for both work and combat and the cost of a prosethetic is low. Bionic legs offer a large improvement over even organic legs but are significantly more expensive to make or buy.

Compared to a wooden foot, a prosthetic leg only offers +2.5% Moving (base +0.115 c/s). If damage is limited to the foot or toes, then a wooden foot is mostly sufficient; the extra components can usually be put to better use than making a prosthetic.
