Immediately after another creature's turn, you can choose yourself or an ally within 60 feet of yourself that can see or hear you to take a Legendary Action. This action is one of the following: Attack (one attack only), Dash, Disengage, Dodge, Hide, Magic (cast one cantrip only), or Utilize. A creature can only take one Legendary Action each round. When a creature takes the Dash or Disengage action in this way, the benefits of that action last until the end of the creature's next turn.
You can use this feature to take three Legendary Actions and regain all expended uses when you finish a Short or Long Rest.
