Tyrannic Kiss

You kiss a creature who is in melee range. A target must succeed on a Wisdom saving throw or take 3d8 psychic damage and your oponend is frightened.
On a failed save the target takes half the damage.

If your opponent is frigthend you can use your bonus action to command it to your will. It will do what ever you say, even harm it self, as long as your command is not suicidal.
