I've always said I want the ability of flawless persuasion. I might not be able to get to work immediately, but I can persuade them I was on time. Or even to just give me the day off (and pay me anyway). I might not be able to fly, but I can persuade pilots to do that for me. I might not be able to shapeshift, but I can convince people all is not what it seems. I might not be able to read minds, but I could persuade people to tell me what they're thinking and be honest about it. And so on.
