Boxer-puncher
Boxer-punchers are the jack of all trades of boxers, using movement, power and flurries in a tactical manner. These boxers tend to be more strategic and mindful, seeing the boxing match as a game of chess, were they must apply the correct solution to a certain situation.
Boxing Superiority
When you choose this style at 3rd level, you learn maneuvers that are fueled by special dice called superiority dice.
Maneuvers. You learn three maneuvers of your choice as a fighter. Many maneuvers enhance a melee attack in some way. You can use only one maneuver per melee attack. Attacks you enhance with maneuvers can only be melee attacks. You learn two additional maneuvers of your choice at 9th, 13th, and 17th level. Each time you learn new maneuvers, 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.
The size of the dice also increases, becoming a d10 at 9th level and a d12 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)
Tactical Punches
At 9th level, you have advantage on attack rolls with unarmed strikes and glove weapons against a creature affected by a maneuver.
Fighting Vigor
At 13th level, whenever you deal damage to a creature with a melee attack enhanced with a maneuver, you gain temporary hit points equal to half your boxer level + your Constitution modifier. You can use this feature a number of times equal to your Constitution modifier (minimum of once) and regain your uses after a short or a long rest.
Relentless
Starting at 17th level, when you roll initiative and have less than your maximum superiority dice remaining, you regain 1 superiority die.
