Advantages
The advantages are presented in alphabetical order.
Beginner’s Luck. When you attempt a check with gaming set or a Dexterity (Sleight of Hand) check, you can expend one superiority die and add it to the roll. Roll the superiority die again, and subtract it from the opposed check or DC of the subject.
Eidetic Memory. When making an Intelligence check to recall lore you might know, you can expend one superiority die and add it to the roll to treat a roll of 9 or under as rolling a 10.
Endurance. By expending a superiority die, you can ignore half the rolled value of the die levels of exhaustion until you finish a long rest.
Flouette. When you take the attack action to shove a creature, you can expend one superiority die and use a Charisma check and add the superiority die and your proficiency bonus to the roll instead of rolling Strength (Athletics). You may also use this ability to perform a small feat of Dexterity or Strength, such as pulling a tablecloth from a table and leaving the dishes in place.
Honeyed Words. By expending one superiority die, you can deceive or persuade a number of creatures equal to the die roll without making a check. If seeking an audience with an influential creature, you can expend one superiority die to find out how.
Incite. By expending one superiority die, you can draw the attention of any creature who can see and hear you in a boorish display for as many minutes as the result rolled on the die. You cannot perform any other action, but any creature attempting any draw the attention of the crowd has disadvantage on their ability checks and any creature trying to avoid the attention of the crowd has advantage on their ability checks. This effect ends immediately if anything harmful happens to a creature watching your display.
Just a Rat. When you fail a Dexterity (Stealth) check, you can expend one superiority die to reroll the Dexterity (Stealth) check with disadvantage add the superiority die to the roll.
Medicate. By expending one superiority die you can drink or administer a potion as if interacting with an object during your movement or action.
Monster Whisperer. When you attempt a Wisdom (Handle Animal) check, you can expend one superiority die and add it to the roll to attempt the check on any creature with an Intelligence score of 7 or less contested with a Charisma saving throw. If you succeed on the check, the creature refuses to attack you unless coerced or attacked by you.
Paranoia. You can expend one superiority die to use the bonus action granted by your Cunning Action as a reaction. If you are surprised, you can expend a die this way when you roll initiative to no longer be surprised at the start of the encounter.
Parkour. When you move across any obstacle requiring a Strength (Athletics) or Dexterity (Acrobatics) check, you can do so without a decreasing your speed so long as you end one round worth of movement on stable terrain. You can expend one superiority die to ignore difficult terrain for as many rounds as rolled on the die.
Rodeo Grip. When you take the attack action to attempt a grapple, you can expend one superiority die to add it to the roll and ignore size restrictions for the check. If the subject is larger than you, you gain the grappled condition instead of the subject as you climb onto their back. The subject’s speed is halved, and all checks made by the subject against you have disadvantage while all checks you make against the subject have advantage. If the subject is your size or smaller, you gain the grappled condition and the subject gains the restrained condition.
Sleuth. You may make Intelligence (Investigation) and Wisdom (Perception) checks with either ability check. You can expend one superiority die to make one discovery within 30 feet that would normally require an ability check, such as the location of a secret door, hidden message in a text, how a corpse died, or the weak point of a structure that would allow it to collapse.
This is a first swag at it, so any feedback is welcome.
