You have mastered the art of fighting with two weapons. You gain the following:
Once on your turn, when you make a melee weapon attack and score a critical hit or reduce an enemy's HP to 0, you can immediately make an extra melee weapon attack against a target within your melee weapon's range.
Weapon Feint
Once on your turn, you can use your bonus action to make a feint attack, granting advantage on your next melee weapon attack this turn. If this attack hits, you deal an additional amount of damage equal to your choice of your strength or dexterity modifier.
