Some characters have unusual abilities that allow them to alter one or more things about their own bodies,
such as Growth or Intangibility.
It is possible for a character to take a custom Metamorphic trait and name it something like Chemomorph
or Husk Shedding as long as the players and GM involved reach a consensus on what that means in actual play.
Additionally, some abilities which are not normally considered Metamorphic traits might be classified as Metamorphic
for a given character. For instance Invisibility could reasonably be considered a Metamorphic ability on a
character who alters their own body to become translucent.
However, the following traits are standardized and assumed to be available to characters with sufficient justification within the setting.
