Unlucky

You have inexplicable bad luck that seems to kick in at just the wrong moment for you as well as your enemies.

• You have 3 luck points. 
• You can spend one luck point when a creature you can see makes an attack roll, ability check or saving throw. Roll a d20, and then whichever die rolled the lowest is used. If more than one creature spends a luck point to influence the outcome of a roll, the points cancel each other out; no additional dice are rolled.
• You regain your expended luck points when you finish a long rest. Additionally whenever you have advantage on a roll you can choose to instead roll with disadvantage. Doing this restores 1 luck point. You can do this a number of times equal to half your proficiency bonus rounded down every long rest.
