You can study a character for 10 minutes to learn information about them. They must be within 30 feet and you must be able to see them for the full 10 minutes to gain this feature's benefits. You gain advantage on all Persuasion, Deception, Wealth, Reputation, and Intimidation checks made against them within the next hour, but if you fail any of those checks against them during this time-frame, they become immune to this feature for the next 24 hours. (A character affected by Mind Blank cannot be affected by this feature.)
