Distracting Hand

"A spectral hand  appears by the target, slapping, yanking on, or making rude gestures at the target, distracting it from the dangers of battle and opening them up for attack."

You summon a ghostly hand that distracts the target.  The target must make a Wisdom saving throw.  On a fail, the target is distracted and any creatures within melee range of them can use their Reaction to make an attack of opportunity against it.
