Drain Luck

One creature of your choice within range must make a Charisma saving throw. On a failed save, for the duration, whenever the target makes an attack roll, a saving throw, or a skill check, roll a d6 and subtract the number rolled from the creature’s roll. Whenever an attack roll is made against the target, add a d4 to the attack roll. A remove curse, or wish spell also ends it. 

At Higher Levels. When you cast this spell at 3rd level or higher, you can target one additional creature for each spell level above 2nd.
