Combat Superiority
When you choose this archetype at 3rd level, you learn maneuvers that are fueled by special dice called superiority dice.
Maneuvers. You learn three Throws of your choice, which are detailed under “Throws” below. Many Throws enhance an attack in some way. You can use only one Throw per attack.
You learn two additional Throws of your choice at 7th, 10th, and 15th level. Each time you learn new Throws, you can also replace one Throw you know with a different one.
Additionally, you may only use a Throw on a weapon attack at range with the Thrown property.
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 7th level and one more at 15th 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)
Nimble Fighter
At 3rd level, you gain proficiency in acrobatics and stealth.
Additionally, you may take the dodge or disengage action as a bonus action. You may only do this if you are not wearing heavy armor, a shield, or any armor that imposes disadvantage on Stealth checks.
Throws
The Throws are presented below.
Aerial Throw
When attacking a creature that is in the air due to natural flight or a spell, you can expend a superiority dice to attempt to knock it to the ground. After you hit a creature that is flying due to a spell or natural flight, add your superiority dice to the weapons damage. The creature must then make a strength saving throw. On a failed save, the creature plummets to the ground and falls prone, taking fall damage reduced by half.
Assisting Throw
When your ally is targeted by an enemy with an attack within your weapons effective range, you may expend a superiority dice to make an attack against the creature. You can use your reaction to make this attack, and if it hits, add the superiority dice to the damage roll. If the attack hits, the enemy must make their attack with disadvantage.

When you hit a creature with an eligible weapon attack, you can expend one superiority die to attempt to cripple the target.
