Changelings mature slightly faster than humans but share a similar lifespan — typically a century or less. While a changeling can transform to conceal their age, the effects of aging affect them similarly to humans.
Changelings reach maturity slightly faster than humans and live as long as humans do, typically about 100 years.
Changelings born from two changeling parents are born in their natural form: pale, slender, with colorless eyes and white hair.
Changeling Appearance
Their true skin is usually grey or pale white, and their facial features are blank slates to an unnerving degree. They're typically thin and gaunt, and their hair is usually silvery with an occasional green or pink tint.
The true form of a changeling is a bit paler than a typical human with slightly elongated limbs. Their eyes are colorless and ringed by black as pictured in the artwork above by Julia Zhuravleva. They have no body hair, but the hair on their head can be platinum, white, or silver.
The changelings left by the Mamuna were said to have a noticeably different appearance; an abnormally large abdomen, unusually small or large head, a hump, thin arms and legs, a hairy body, and long claws. Mamuna changelings would also get their first set of teeth prematurely compared to a human baby.
Changelings don't inherently recognize each other. If they don't want to be recognized then when they do something suspicious it would be an insight check against the changelings deception, which the changeling has advantage on. A changeling could have expertise in insight from divergent persona.
Changelings are often very mischievous growing up, as they get older they tend to calm down and begin being more helpful. Changelings though do to their mischievous behavior are often depicted as evil creatures and sent by the devil to take the place of a human parents infant.
Conversation. By RAW changelings revert when they DIE but not when they are unconscious (it would be hard to maintain a long term masquerade if you revert when you sleep!). I bet suggested that a piece of a Changeling — such as cut hair — WILL revert, but that this is slow and may take up to 24 hours.
Changeling Reproduction
If a changeling in a female form conceives a child, she loses the ability to change her gender until after the child is born.
Size. In their natural forms, changelings average between 5 and 6 feet in height, with a slender build. Your size is Medium.
The short version is that a Changeling can shapeshift to a form that can produce sperm to impregnate someone, and can shapeshift to a form with a uterus and eggs to get pregnant, but a pregnant Changeling cannot shapechange to a form without a uterus without ending the pregnancy.
Changelings don't need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) After resting in this way, you gain the same benefit that a human does from 8 hours of sleep. Languages.
17. As a playable race, changelings have the following abilities: Shapechanger: Using an action they can change their appearance and voice at will, even adapting their size between small and medium in some cases.
You can't increase or decrease the number of limbs you have, and their basic arrangement needs to be in roughly the same location on your body (2 near the head and 2 near the rear). So, you can't, become a winged demon or angel, as the wings of those forms are additional limbs.
As for being tattooed, changelings can definitely be tattooed, and they can just as easily erase the tattoo with a moment's thought.
Changeling blood is green, unlike most other animals. Changelings, despite their thinly and seemingly fragile frame, are capable of surviving otherwise fatal injuries thanks to their magical abilities.
Babies are most at risk, although the Sidhe fear nothing more than iron and fire, so a pair of scissors or tongs may be left near to the crib, or the crib left close to a fireplace, and draping a garment belonging to the father of the child over the baby as it sleeps is also said to be a preventative.
A changeling can eliminate or add traditional physical disfigurements - such as scars or birthmarks - when changing shape.
When the human part of a changeling dies (Banal Death), the fae self may live on, but that changeling will never come into existence again. Commoners are reborn into another human host who has a different appearance and upbringing from the previous mortal seeming.
changeling, in European folklore, a deformed or imbecilic offspring of fairies or elves substituted by them surreptitiously for a human infant. According to legend, the abducted human children are given to the devil or used to strengthen fairy stock.
Will a legless changeling regrow both legs when it copies someone? I say no. The changeling can change their coloration, hair length, sex, height, and weight, but they can't change their number, arrangement, or function of their limbs, because nothing in the feature says they can or even hints at it.
Appearance. In their true form, or their form "at rest", changelings have pale skin, colorless eyes that can be completely white or completely black, and white or silver-white hair.
