Impostor (feat)

You have developed impeccable mimicry and acting skills. You gain the following benefits:

• Increase your Charisma score by 1, if doing so does not exceed your maximum score for that ability.
• You can mimic the speech of another person or the sounds made by other creatures. You must have heard the person speaking, or heard the creature make the sound, for at least 1 minute. A successful Wisdom (Insight) check contested by your Charisma (Deception) check allows a listener to determine that the effect is faked.
• You have advantage on Charisma checks made to pass yourself off as a different creature.
• You gain proficiency with the disguise kit.
