Stoneskin gland

Stoneskin gland

This bionic gland releases chemicals and nanomachines that transform the user's skin into a built-in suit of armor. The whole epidermis thickens and hardens to resist burns, while jointed exterior keratin plates form everywhere they can - including the head and face. While it's very difficult to physically hurt someone using this implant, the plates and hard skin significantly reduces the user's physical attractiveness.

The Stoneskin Gland is an implant added by the Royalty DLC that gives the host pawn natural armor, in exchange for making them uglier and slower. It is the most protective and has the largest penalties of the three skin gland implants, being stronger than both the toughskin and armorskin glands.


Stoneskin glands can be crafted at a Fabrication bench once the Skin hardening research project has been completed. The required techprint can be obtained either by trade or completing quests for the Empire. They require Plasteel 25 Plasteel, Advanced component 8 Advanced components, 26,000 ticks (7.22 mins) of work, and a Crafting skill of 8.


Pawns that are implanted with a stoneskin gland gain a bonus to Sharp/Blunt/Heat Armor by 70/30/50% respectively, considered as its own layer for the purposes of armor calculations. It also reduces pawn beauty by 2 and multiplies moving by 85%, a 15% reduction. In turn, the penalty to moving reduces the move speed, hunting stealth, and melee dodge chance of a pawn.

The armor rating of the gland still protects body parts replaced by artificial body parts, even if they would not logically have skin. This is likely to prevent them from being a detriment to survivability.


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 2,500 ticks (41.67 secs) of work, 1x medicine of herbal quality or better, and a Medical skill of 5.

If the operation fails, the part will be destroyed.


Stoneskin glands provide a moderate amount of protection. While not to the point where it's "very difficult" to hurt a user as the description implies, a 30% to 40% reduction in incoming DPS for most weapons is significant, and better than that of a set of normal steel plate armor while also stacking with any armor option.

A stoneskin gland severely reduces the beauty of a pawn, which causes a −40 opinion debuff from other pawns.

Disfigurement adds -15 opinion and while it doesn't affect the beauty stat of a pawn, it disables the effect of positive beauty on the pawn. Disfigurement stacks with the effect of negative beauty possibly leading to -55 opinion on a pawn with less than or equal to -2 beauty.

It should be noted that a beauty greater than +/ 2 does not have any effects on gameplay, aside from the above mentioned disfigurement.

Here is a table of the total effects of the stoneskin gland, combined with other things that modify beauty.
