Bad Luck Charm

You have learned how to brush your bad luck curse onto others, weakening them when you most need it.

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• When a creature you can see within 60 feet of you makes an attack, ability check, or saving throw you force the target to roll a d4 and subtract the number rolled from the attack,check, or saving throw. You and the target then both suffer psychic damage equal to the amount subtracted. Once a target has suffered this curse, they become immune to it for the next 24 hrs. 
  You can use this feature a number of times equal to your proficiency modifier and regain all uses after a long rest.
  
  The die for this feature grows when you reach 5th level (d6), 11th level (d8), and 17th level (d10).
