Practiced Liar

You have spent a lifetime lying to everyone around you. As an expert liar, you gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 20
• If you are not Proficient in Deception, you gain Proficiency. If you are Proficient in Deception, you gain Expertise
• Pick 3 well-defined and specific lies your character tells often; you and your DM must agree upon the terms of these lies prior to taking this feat. Every time your character tells one of those lies, roll a Deception check. If your Deception check beats the Passive Perception of those being lied to, they will not be able to roll an Insight check against your lie; if your Deception check does not beat the Passive Perception of those being lied to, they are able to make an Insight check and you will roll for Deception again.
