"Right now the spells I have available to me are another casting of the spell I'm using to communicate with you and a couple of spells that produce light. I suppose if light is harmful to you that could make me non-helpless. One is Dancing Lights, which allows me to create four lights of approximately lantern intensity that I could manipulate the position of. They would last for sixty seconds. The other is simply Light, which makes a single targeted object shine like a torch for, for a wizard of my tier, two hours and fifty minutes. In order to prepare any other spells, I would need a written record thereof, which conventionally come in the form of spellbooks but can be written on individual sheets of paper just fine, or even tattooed on my person. As you can see, I have no tattoos. In addition to my spellcasting abilities and my divinely inflicted attributes, I have a racial immunity to magical sleep. I can't think of how to prove any of this to you. I can expand on how wizardry works if you like but I'm seventeenth-tier and people who are advanced in a craft and haven't specialized in teaching are notoriously bad at explaining things to beginners so you're going to have to ask specific questions."
