You return a blow so quickly that your opponent is shocked.

A probing blow allows you to take the measure of your foe.

When you activate this maneuver, you take the Attack action and make a weapon attack, as well as any additional attacks granted by Extra Attack. Until the start of your next turn, when you deal damage to a creature you learn its current hit points, hit point maximum, immunities, resistances, and vulnerabilities. 

You tune your senses, focusing on the fight at hand.

By relying on your training and countless hours of repetition, you can easily manipulate the battlefield to position yourself where your strikes are able to inflict the most harm.

Your weapon attacks score a critical hit on a roll of 18–20. If you already have a feature that increases the range of your critical hits, your critical hit range increases by 1 (maximum 17–20).

You feed off the adrenaline from a solid strike and turn that energy into frenetic movement.

Move up to your Speed and make a melee weapon attack against a creature. On a hit, for the next minute your Speed is increased by 10 feet.

You execute a perfect retreat that distracts enemies and allows your companions to fall back beside you.

You take the Disengage action, and up to 3 allies within your reach can use their reactions to take the Disengage action and move their Speed.

By focusing on keeping enemies off-balance, you help allies attack more effectively.

Whenever you hit a creature with a melee weapon attack, you can also take the Help action. On a critical hit, the target of your Help action can use their reaction to take the Dodge action.

You interpose yourself to take a hit for your ally.

When an ally within your reach is hit by an attack, you can use your reaction to swap places with them and become the target of that attack, taking half as much damage as normal.

By focusing on balance and heft you can throw whatever you have in hand with deadly accuracy.

While you are wielding a weapon that does not have the heavy or special property, it gains the thrown property.

You aim carefully at your opponent’s most vulnerable spot.
