Changeling:
As an action, a Clawdite may suffer 3 strain and make an Average Resilience check.
If the Clawdite succeeds, she changes her appearance to match that of a silhouette 1 character whom she has observed before,
An observing character must make opposed Perception vs Deception check to detect that something is amiss with the impersonated characters likeness, mannerisms, or behavior.
As always, the DM can add d6 for situational effects that might affect the check, such as if the Clawdites garb does not match expectations or if the Clawdite has studied the impersonated individuals mannerisms closely,
