Martial Spirit

Ability Score Increase. Increase your Strength, Dexterity, or Constitution score by 1, to a maximum of 20.

Momentum Surge. When you score a critical hit with a melee weapon attack or reduce a hostile creature to 0 Hit Points with one, you can immediately move up to your Speed. This movement does not provoke opportunity attacks. If you end this movement within reach of another hostile creature, you can make one melee weapon attack against it as part of the previous Attack Action. You have Advantage on this attack. You can use this benefit a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

Martial Sweep. When you take the Attack action on your turn, you can replace one of your attacks with a sweeping strike. Make a single melee weapon attack roll and compare the result to the Armor Class of any number of creatures of your choice within your weapon's reach. Roll damage once and apply it to each creature hit by the attack. Once you use this feature, you must finish a short or long rest before you can use it again.
