Master Debater

Skilled at argumentation and analytics, you gain the following benefits:

• Increase your Intelligence score by 1, to a maximum of 20.
• You gain a new skill: Intelligence (Persuasion). Whenever a check calls for a Charisma (Persuasion) check, you may substitute this skill instead.
• You gain proficiency in the Intelligence (Persuasion), independent of any proficiency with Charisma (Persuasion. (At the time of this feat's creation, you will need to manually add it to your character sheet.)
• If a creature has an Intelligence score of 8 or lower, they have Disadvantage on Wisdom (Insight) checks to see through your arguments, but a creature with an Intelligence of 4 or lower cannot be persuaded in this manner, and automatically succeeds on checks against Intelligence (Persuasion).
