Thespian

Your mastery of the dramatic arts is useful both on and off the stage.

Raise your Charisma attribute by 1, up to the attribute cap of 20.
When adopting another persona, gain advantage on Deception and Performance checks.
You may perfectly mimic the voice or sounds of another creature. A creature with a reason to be suspicious may attempt a Wisdom (Insight) check opposed by your Charisma (Deception) to see through your ruse.
