Mimicry Advantage
You can duplicate any simple sound (alarm, gunshot, etc.) by listening to it for one second and making a successful IQ roll. You can also imitate voices by spending at least 10 seconds listening to them – live, recorded, or remotely – and making an IQ roll.
This trait gives you no special ability to stun or deafen others with loud sounds, or to speak unpronounceable magic words. Buy any such capabilities separately.
