The Bane of Matt Cauthon

An ancient curse, or blessing if one wishes to view it as such, passed down through generations by a noble hero once cursed with the unluckiest luck one could ever experience. Creatures with this feat can, thrice per short rest, automatically succeed on a check/save/attack roll. When the target uses this spell they have disadvantage on every check/save and their enemies have advantage on them until their next short rest.
