You sprint through your enemies, striking at every one you pass.

You take the Dash action. During your turn, any time you become adjacent to a creature, you can make a melee attack against it using a weapon that has the dual-wielding or finesse properties. 

You cannot attack the same creature twice in a row in this manner or make more attacks than your proficiency bonus.

An expert parry turns a hit into a miss.

You spin around, gathering momentum as you strike your foes harder and harder.

Make a melee weapon attack against any number of creatures within 5 feet of you, making a separate attack roll for each target. For each subsequent hit after the first, you deal an additional 1d6 damage.

You focus on moving so swiftly and with such subtlety that nothing can stop you.

You react and attack quicker than the eye can see.

After rolling initiative, you can use your reaction to treat your initiative as if you had rolled a critical success.
