Chin Hexfield

You emit a subtle, unsettling vibration from your chin.
One creature of your choice within 10 feet must succeed on a Wisdom saving throw or suffer a minor curse until the start of your next turn.
While cursed, the creature subtracts 1 from its next attack roll.
At 5th level, the penalty becomes -2; at 11th, -3; at 17th, -4.
