You have the power to give someone, anyone you want, the world's worst sore throat, so bad they cannot talk and can barely swallow. But that's not all. You also have the power to give someone a horrible, banging headache. You also have the power to give someone a nosebleed. You also have the power to give someone a really bad toothache. Finally, you have the power to make someone feel really nauseous and puke. Your pick.

The people you choose to make ill will suffer for up to 24 hours, then they will recover.

You can wield this power at any time, for any reason. You can strike the same person over and over if you so wish. There's no consequences or bad karma for you.

How will you use this power? Who will you go after, and why?
