Have it give you a luck point and maybe also the ability to spend 2 luck points for a full reroll after you've failed a save, which includes the +2 bonus, maybe.
Note the version I gave isn't limited to saves. It's +2 to any d20 roll you care to spend a luck point on after seeing the result. (I'm tempted to phrase it such that you get to know if +2 would make the difference or not, first, even, if that would make it not too much.)
