As an action, you can assail a hostile creature within range of your weapon with a series of rapid, superficial strikes, putting the target on the defensive. Make an attack roll with this weapon. On a hit, the target’s mental focus shifts to defending itself. All attack rolls against the target have disadvantage until the start of your next turn, but the target has disadvantage on the next Int, Wis or Cha saving throw it makes before the start of your next turn.
