Unflinching Intimidation

You either devise a string of threats or a threatening action, laced with subtle enchantments, you can preform to instil fear into the very soul of a creature that attacked you. If the target can hear or see you (though it need not understand you), it must succeed on a Wisdom saving throw or take 1d6 psychic damage and have disadvantage on the next attack roll it makes before the end of its next turn.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
