race features:
Size. Depending on what they have awoken in, a Living
Heirloom can stand anywhere from 4 feet to 7 feet tall and
weigh upwards of 150 pounds.
Sentient Construct. Even though you are made from
nonorganic material, you are a sentient lifeform. You are
immune to disease and you don't need to eat or breathe.
You don't require sleep, but you must enter an inactive state
for 8 hours to gain the benefits of a long rest.
Bloodless. You are immune to poison damage and the
poisoned condition.
Inanimate Disguise. While you remain motionless, you
have advantage on any ability checks made to disguise
yourself as an inanimate version of your form.
Subrace.
The three main kinds of Living Heirloom are
Statue, Mannequin, or Armor Set. Choose one of these
subraces.
Statue
You have awoken within a stone statue. For a statue to awake,
it must have a head, body, arms, and legs. A Living Heirloom
of this kind is imbued with proficiency in a skill that it was
depicted as doing before it gained sentience.
Skillful Depiction. You gain proficiency in one skill of your
choice.
Stony Exterior. Your body is completely made from stone,
granting you a +1 bonus to Armor Class.
Mannequin
You gained your consciousness in the body of a mannequin.
You have sat idly through the years, modeling hundreds of
articles of clothing and wigs of all kinds. A Living Heirloom of
this kind is imbued with skill in disguise and subterfuge, everchanging
their appearance and personality to suit the
occasion.
Verbal Avidity. You gain proficiency in one of the following
skills: Deception, Intimidation, Performance, or Persuasion.
When you finish a long rest, you can choose to replace the
proficiency you gained from this trait with one of the other
skills listed.
Masquerade. You can cast the disguise self spell with this
trait, using Charisma as your spell casting ability for it. You
can cast this spell a number of times equal to your proficiency
bonus. After you use this trait, you can't use it again until you
finish a long rest.
Armor Set
You awoke in a suit of full plate armor, watching silently over
your family. For a suit of armor to awake, it must be a suit of
full plate. A sentient suit of armor of this kind is imbued with
military prowess.
Innate Combat Prowess. You gain proficiency with one
martial weapon of your choice, and shields.
Fully Plated. Due to the fact that you are a sentient set of
armor, you are ill-suited to wearing additional armor.
However, you have a base AC of 16 (your Dexterity modifier
doesn't affect this number). You gain no benefits from wearing
additional armor, but if you are using a shield, you can apply
the shield's bonus as normal.
