race features:
Size
Manikins can be small puppets or imposing armors. You are Medium or Small. You choose the size when you select this race.
Constructed Life
You are made of inanimate material but have been given life and a soul, making you a living being for the purpose of all effects that require it. You are a Humanoid. You are also considered a Construct for any prerequisite or effect that requires you to be a Construct.
Living Material
Manikins don’t need to eat, drink, or breathe. In addition their metallic mind is incorruptible, they have advantage on saving throws against madness.
Lightning Heart
You have resistance to lightning damage.
Born to Serve
Manikins are made to be unable to hate or resent their creators. This lapse in judgment affects you in all circumstances. You have disadvantage on Wisdom (Insight) checks.
Mendable Body
Either by performing 2 hours of work with appropriate Artisan's tools or by using the mending cantrip, you can re-attach your lost limbs, as long as they have not been destroyed. If your limbs get permanently lost or destroyed, they can be replaced by spending 1 workweek of work with appropriate Artisan's tools as well as 50 sp of appropriate materials. Alternatively they can be replaced through the Regenerate spell, as normal. If your head or heart get permanently destroyed, they can not be replaced by any means short of a Wish or True Resurrection spell, as they contain the essence of your soul.
Modular Plating
Your body can be upgraded with built-in defense layers, which determine your armor class. You gain no benefit from wearing armor, but if you are using a shield, you apply its bonus as normal.
Through 8 hours of work in a specialized workshop, you can alter your defensive layers to any armor type or back into your Unarmored state. To do so you require an undamaged armor of the type you want to upgrade your body with, with which you need to be proficient. By doing so, you gain the effects of wearing the armor (e.g. Armor Class, magical benefits or Disadvantage on Stealth checks), but the armor itself and therefore its weight becomes part of your body.
Unarmored. Your AC equals 11 + your Dexterity modifier.
Subraces
Manikins can be created for a variety of purposes, but they are mostly divided into three subraces: Custodian, Handler and Thespian. Choose one of the available subraces.
