Changeling

A small lineage of natural shapechangers who alter facial structure, coloring and voice within a limited humanoid range and live among many cultures.

Changelings mature quickly and show their age mainly in their final decade, which the cultures they live among often fail to notice.

Features

Shapechange

As an action, you can alter your physical appearance to mimic that of a humanoid you have observed for at least 10 minutes. You can adjust apparent height (within 6 inches), build, facial structure, hair, skin tone, voice, and minor distinguishing marks. Your size, ability scores, hit points, and statistics remain unchanged. Weight changes are illusory and do not let you pass through spaces too small for your true mass. Checks made to see through your disguise have disadvantage. The change lasts until you end it or you fall Unconscious. The transformation is physical, so spells that detect illusion do not reveal it.
Mutable Mind

Your sense of self is more fluid than that of fixed-form lineages. You have advantage on saving throws against being Charmed and against effects that would compel you to act against your interests. While in a shifted form, you also have advantage on Charisma (Deception) checks made to maintain that form's social identity.
Unmarked Origin

You learn the speech of the cultures you move among. Each time you gain an Intelligence ability score increase, you also learn one additional language of your choice. You can read, write, and speak any languages you know without a native accent.
Familiar Tongues

You begin play with Common and one additional language of your choice.
