Unlucky

For some people, luck just doesn't seem to be on their side. You are frequently the victim of some unusual bad luck.

You have three bad luck points. 

Whenever an ally you can see makes an attack roll, ability check, or saving throw,  you can spend one bad luck point to give them advantage on the d20 roll.

As a consequence, the DM may impose disadvantage on a d20 roll you make or advantage on a roll made against you within the next 10 minutes.

This feat cannot be taken with the Lucky feat. You regain your expended bad luck points when you finish a long rest.
