Distract

Choose a target in range to make a Wisdom saving throw. On a failure, the target's attention is diverted to a point you choose within 60 feet until the start of your next turn and it has disadvantage on Perception checks. The phenomenon that distracts the creature is invented by the creature's own mind, though they remain unaware of this fact. The creature is not compelled to investigate. 

Whether it succeeds or fails the saving throw, the creature is unaware you tried to cast a spell on it.
