Jsk Feats:Luck

You have inexplicable luck that seems to kick in at just the right moment. You regain one expended luck point when you finish a short rest, and all your expended luck points when you finish a long rest.
 * You have three luck points.
 * Whenever you make an attack roll, an ability check, or a saving throw, you can spend one or more luck points to get a bonus to the roll equal to your proficiency bonus. You can use more than one luck point on a single roll, but you must decide how many luck points to use before you roll any dice.
