You were created to be an addition to a family, either as a member or a caretaker. In order to fullfil your purpose, you were designed with the following in order to keep you safe and help you keep others in your family safe:

You have advantage on saving throws against being poisoned, and you have resistance to poison damage; you don’t need to eat, drink, or breathe; you are immune to disease; you don’t need to sleep, and magic can’t put you to sleep.

Designed to keep up with the mortal life around you, you can easily maintain their normal 30 ft pace.

You were designed to blend in as much as possible with your family. As such, you were built to be of a similar height as an average adult.

Although you are able to get tired the same way your mortal cohorts do, you do not need to sleep in the same way as them to relieve this. Rather than sleeping for eight hours, you only need to remain motionless for six hours. During this time, you may appear to be inactivated to the outside world, but you are still able to see and hear as normal.

Like most other warforged, living dolls normally take comfort from order and discipline. Because of this, they tend towards law and neutrality. However, over time some may absorb the morality, or lack thereof, of their family.

Constitution increases by two, and one ability of choice.

Due to their mechanical nature, living dolls do not have a childhood unless specifically designed as such by their creator. As such, they are considered to have reached the age of maturity from the first awakened moments. As they do not age, they are considered quasi-immortal, often living alongside many generations of the same family before their power source runs out or their body breaks down beyond repair. They are immune to magical aging effects.

Your body, with it's metal frame covered in brushed enamel, is able to absorb hits better than your squishier, mortal counterparts, granting a +1 to your AC. If you choose to wear armor, you are only able to don armor you are proficient in, as this is the only armor you fully understand. To don armor, you must spend a full hour in contact with it and absorb it into your body. It takes an hour to doff armor. You can don or doff armor while resting. While you are alive, armor cannot be removed from your body unless you are willing.

Your creator ensured that some of their skills were passed on to you during your creation. As such, you gain proficiency in one skill of your choice.

Your creator ensured you could communicate as best as they could, and granted you their full knowledge of both Common and one other language.

Despite having the outward build of a regular humanoid, the mechanical components of your body make you significantly heavier than one would expect.
