From D&D Wiki
A life of disrepute has lead to you gaining skills in disreputable combat. Street fights, underground fighting rings, and bar fights were your training ground rather than any formal teaching. Your skills have are best used to weave in and around the battleground hitting enemies when they are least able to defend themselves.
At 3rd level, you learn maneuvers that are fueled by special dice called superiority dice.
Maneuvers. You learn two maneuvers of your choice, which are chosen from the list of maneuvers available to fighters with the Battle Master archetype. Many maneuvers enhance an attack in some way. You can use only one maneuver per attack. You learn one additional maneuver of your choice at 5th, 9th, 13th, and 17th levels. Each time you learn a new maneuver, you can also replace one maneuver you know with a different one.
Superiority Dice. You have four superiority dice, which are d8s. A superiority die is expended when you use it. You regain all of your expended superiority dice when you finish a short or long rest.
You gain another superiority die at 9th level and one more at 17th level.
Saving Throws. Some of your maneuvers require your target to make a saving throw to resist the maneuver’s effects. The saving throw DC is calculated as follows:
Maneuver save DC = 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice)
At 3rd Level you can also use Dodge as a bonus action from Cunning Action.
At 7th Level you gain proficiency in Intimidation. You gain Advantage on all Intimidation checks and may add your Strength modifier if the target is restrained or grappled.
Improved Combat Superiority
At 10th level, your superiority dice turn into d10s. At 18th level, they turn into d12s.
Starting at 15th Level, Any attacks that hit a prone or incapacitated target is a critical hit.
