Age: Changelings reach adulthood at the age of 16. Their fey heritage allows them to live much longer than humans, up to 200 years.
Lifespan. Changelings reach maturity slightly faster than humans and live as long as humans do, typically about 100 years.
Age. 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.
You can change directly from one form to another
You stay in the new form until you use an action to revert to your true form or until you die. "Stay" means "to remain in the same state". This means there is no duration, and unless you revert or die you will remain in the new form.
Age. Changelings mature slightly faster than humans but share a similar lifespan — typically a century or less.
It was suggested that Changelings were biologically immortal and therefore never died of old age (DS9: "Children of Time", "Behind the Lines") Laas was over 200 years old. (DS9: "Chimera") However, it was possible to kill Changelings by a number of means. Severe cases of radiation poisoning could prove fatal.
A changeling can't make the wings at all. If they had wings, like from a class feature or something, then they could look like an Aaracokra with wings because they will have those limbs at that point.
Most often, the mother begins to carry twins, and one of the twins is a changeling. There are extremely rare cases of being born alone, or as part of triplets. In the rarest of cases, the other twin is a hag.
Most changelings don't know they're changelings.
Though they may always feel somewhat different or removed from human life, most changelings are too young to understand who they truly are.
As for being tattooed, changelings can definitely be tattooed, and they can just as easily erase the tattoo with a moment's thought.
Unlike doppelgangers, which are entirely genderless, a changeling does have a default gender that manifests in adolescence, but each changeling can adapt his or her form to be of either gender, hermaphroditic (both genders simultaneously), or entirely genderless.
"A human child might be taken due to many factors: to act as a servant, the love of a human child, or malice. Most often it was thought that fairies exchanged the children.
Changelings are typically born with female anatomy, but some prefer to maintain male primary and secondary sex characteristics once in control of this ability.
If you're Irish, you know your child is a changeling if it's sickly and doesn't grow in size like a normal child. Another fairly obvious sign is if it grows a beard or has long teeth. Finally, your child might be far more intelligent than other kids that age, and possess unusual insight.
Within this description there are variants of changelings that show subtle differences. Some have opalescence in their skin (as if it contains various colors instead of just being white) and their eyes can be completely black.
Changelings have red blood like a majority of the other races. Bleeding around others may alert many that the Changeling is not of the same race (should the blood color vary). For this reason, a Changeling will usually choose to take the form of a race with red blood.
Changelings born from two changeling parents are born in their natural form: pale, slender, with colorless eyes and white hair.
Languages: You can speak, read, and write Common and two other languages of your choice.
Good Classes for Changeling
A Changeling makes a fantastic Bard, Paladin, Warlock, or Sorcerer. Really. They're good at all four classes. Bard Changelings benefit hugely from the +2 Charisma, augmenting their spellcasting, bardic inspiration, and talking skills.
Changelings typically have large eyes with narrow pupils, ranging in color from white, to yellow, to black. Hair colors are similar: Light grey, platinum blonde, shades of silver, all the way to the darkest hair color being a light brown.
According to legend, the abducted human children are given to the devil or used to strengthen fairy stock. The return of the original child may be effected by making the changeling laugh or by torturing it; this latter belief was responsible for numerous cases of actual child abuse.
Humans altered by the Wyrd to become Changelings can eventually turn into True Fae themselves. Perhaps the very first True Fae was a human who stumbled into Arcadia, and had to become part of it to survive... then started bringing more humans in... As a corollary to the above.
While changelings can shift forms into a humanoid of similar size, there are restrictions so as not to allow a changeling to "break" every social encounter they come across. Changelings cannot alter themselves enough to change physical sizes (i.e, changing from Medium to Small, etc).
If the changeling has lost a limb, the limb is missing in every form they take. If they haven't lost a limb, every form they take has all the limbs the changeling normally has.
