Changelings reach maturity slightly faster than humans and live as long as humans do, typically about 100 years.
Changelings reach maturity at about fifteen years of age, and they live about as long as humans do.
Like with disguise self, changelings can alter their total height by 1 foot. So they could make both their legs 1 foot shorter, and that would work. In theory, they could even turn both their legs into little stubs, with a 1-inch-tall torso, as long as they elongate their neck to be about 5 feet long.
A changeling can alter his or her gender (and reproductive abilities) as part of using the race's minor shapechange ability. Two changeling parents breed a changeling child. A changeling and a humanoid can mate to produce an offspring with the child having a 50% chance to be of either race.
DS9: "Chimera" suggests Changelings have a lifespan of at least two hundred years, although if Odo was indeed two hundred years old when he traveled back with the USS Defiant in an alternate timeline in DS9: "Children of Time", that would indicate Changelings could live for at least four hundred years.
Some stories tell of changelings who forget they are not human and proceed to live a human life. Changelings who do not forget, however, in some stories return to their fairy family, possibly leaving the human family without warning. The human child that was taken may often stay with the fairy family forever.
A changeling can make it LOOK like they have sharper teeth or claws, but this doesn't actually give them natural weapons; it's a deception. Essentially, it is a form of disguise self, NOT alter self.
Changelings cannot alter themselves enough to change physical sizes (i.e, changing from Medium to Small, etc). It is worth noting that while a changeling could technically shift into something like an aarakocra, their wings would be non-functional.
The Gift of Water is the blessing of the Waterborn. The changelings blessed with it can spend one point of Glamour to allow the changeling to breathe underwater and swim at a terrific rate (equal to twice the character's Speed rating) for the rest of the scene.
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.
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.
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.
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.
A changeling can eliminate or add traditional physical disfigurements - such as scars or birthmarks - when changing shape.
If you want it to be able to grow a tail when it changes into a tiefling or tabaxi, it is your choice. It is also your choice if you want the tail to be prehensile and able to grab and hold stuff. You can appear as a member of another humanoid race which will include things like tails, frills, gills, wings, horns, etc.
Changelings born from two changeling parents are born in their natural form: pale, slender, with colorless eyes and white hair.
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.
Changelings are largely equine in appearance but possess insect-like characteristics. They have black, carapace-like, furless exteriors, webbed manes and tails, blue non-reflective eyes (unlike their queen's), fangs, bent horns, jagged ears, insect-like wings, and holes in their legs.
As a result he can cause himself to look and sound like an exact duplicate of any human, humanoid, or semi-humanoid being of either sex, wearing virtually any kind of clothing. Telepathy: Able to read minds and project his own thoughts into the minds of others within a limited radius.
Changelings lay their eggs directly within food sources her offspring will eat after hatching - namely stashes of meat - that the mother has procured and hidden out of sight in a secure place, such as the abandoned burrow of some small animal, a crevice in rock, or a small hollow in a tree.
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.
Changelings have an interesting relationship with gender as a concept, which is probably part of the reason a lot of the art doesn't find it necessary to distinguish the males with facial hair. As they're changelings though, they can have any kind of hair they want.
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.
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.
While changelings can look like anyone, they do have a true form. Their natural look can be scary to some due to their lack of detail and distinctive features. Their skin tone is always pale, either white or light gray, and they tend to have slender bodies with limbs slightly longer in proportion to other humanoids.
