Elegant duelist

You've learned to press the advantage with your weapon, letting its maneuverability empower your strikes. You gain the following benefits:

• You may add your proficiency bonus to damage with any strike made with a finesse weapon as long as you are not wielding anything in your off hand and are not at disadvantage.
• On your turn, when you hit with a weapon attack  with a melee weapon you are wielding with one hand, while wielding nothing in your off hand, you can make one melee weapon attack as a bonus action.
• If your bonus action hits the target you can preform a disorienting flourish. You fancy foot work leaves your opponent open for your next strike. You may make an acrobactics or deception check opposed by you opponents insight. On a success you have advantage on this target until the end of your next turn. You may only attempt this on a target once every 24 hours.
