Archotech arm

Archotech arm

An artificial arm built by an archotech. It's strong enough to crush a thick hardwood branch in its hand, and precise enough to write a sonnet on a grain of rice. It looks and feels like natural flesh, but it's harder to damage than plasteel. Even if it is harmed, it repairs itself over time. Its internal workings are a mystery to all human minds.

An archotech arm is an artificial body part that acts as a replacement for a pawn's natural arm, increasing Manipulation by 25% per arm while also offering a significantly more powerful punch attack and acting as a body part weapon.


Archotech arms cannot be crafted. They can only be obtained through trade, as a reward from quests, from raiding ancient shrines, from security and hermetic cratesContent added by the Ideology DLC, or at an extremely rare rate from random drop pod crashing.


Body part[edit]

Archotech arms replace the user's organic arm up to and including the shoulder. They are universal and can be installed on either the left or right. The archotech arm has a part efficiency of 150%. This not only fully replaces the functionality of a normal arm - when coupled with the arm body part having a Manipulation importance of 50%, it results in an increase in manipulation of 25% over natural for each archotech arm installed. Manipulation, in turn, affects a great many stats. For a full list of affected stats, see Manipulation.


An archotech arm replaces the natural "Fist" attack of the replaced arm with an over 70% more powerful, but otherwise equivalent, punch.

  • 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 even in a minor way the archotech arm will be destroyed.


    Useful for everything affected by Manipulation including Cooking Speed, General Labor Speed, Carrying Capacity and many others.

    For combat, the increased manipulation significantly improves Melee Hit Chance. When melee fighting without a weapon, Archotech arms do 14 damage per attack, and 7 DPS. For unarmed combat, this is somewhat high, compared to the 8.2 damage from fists and 12 from bionic arms and is in fact roughly equivalent to Normal-quality steel mace. In core, this is only outmatched by the power claw, which does 22 damage and inflicts bleeding wounds, or dedicated implant weapons from the Royalty DLC such as the Venom talon.

    While manipulation does affect Shooting Accuracy, no benefit is gained from having a manipulation over 100%. Thus, the archotech arm only improves the accuracy of pawns with damaged manipulation, and depending on the exact source of the manipulation penalty, potentially only improving it as much as having a bionic or even healthy natural arm already would. While the Archotech arm might not improve accuracy for a healthy shooter, it does create a reserve pool of extra manipulation; a shooter with >100% manipulation could receive a significant injury and continue shooting without decreased accuracy until they drop below 100%.
