Hmmm... choices, choices. Oh! I got one! You make a 15 foot wide and 15 foot tall laser ray, you shoot it randomly. Unfortunately for you, one of the lasers hit a mirror, bounced off your mirror, it hit you, and then you melted.
I'm in a room where I teleported to. it's completely white. The walls aren't breakable. and you can't get in or out. There is a lifetime supply of food and water and I have an impetrable shield around my body and moves with me that cannot be removed.
