Empowered Striker

Prerequisites: Dexterity 13 and no levels in the Rogue class

You know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.

You can use this feature a number of times equal to your character level. You regain all uses at the end of a long rest
