"I mostly just need to know if medicine with instructions like 'administer for pain and fever and not just randomly whenever under the weather, don't give more than X over Y period of time or Z over N period of time, discontinue if any of these four things' are too complicated."

"No, that'd be fine."

"Cool, I can get you some first line stuff of about that complexity. Is this for trading or for if I am not personally available to doctor here at some point in the future, medicines expire eventually like food does."

"I was assuming you might not indefinitely be around to doctor. How long do they take to expire?"

"It depends. Years, for most of the stuff I'd be giving you, it's probably not time to try to figure out vaccines for this population's pathogens."

"Okay. And is actively dangerous once it's too late, or just less likely to work?"

"I can stick to the latter without limiting the selection much."

"That sounds good."

"How much food do you want?"

"I can show you how much space we have to store it."

"That works. For complicated reasons I'm dubious about the history book, can I swap in an extra science book?"

"It seems less useful for the things you wanted us to learn but I'm sure it will be appreciated just as much, so sure."

"The complicated reasons are mostly orthogonal to your level of moral abominability."

"I see."

"How many musical instruments you want?"

"Let's do the food first and then see how close we are."

"Okay! Should I be assuming it has to be ready to eat or that stuff you have to boil or roast is fine?"

"We can cook things that require heat. We can't cook things that require anything more complicated than heat, if it needs to sit over a fire or be dropped in boiling water those don't work."

"You... have heat but not boiling water?"

"That's right. I know of the existence of boiling water from experiments my father did while he was slow."

"I might need to look at your heat thing to guess what kinds of cooking it can do. Like, most food has water in it."

"Sure!" 

They detour by there on their way to look at storage. They have a series of magic crystals that are very very hot to the touch. They might just not actually be hot enough to boil water.

Cam puts a drop of water that is a bit bigger than an ant on one.

That is some water sitting there.

"Okay, maybe at this pressure water doesn't boil at this temperature. This can probably make toast but I don't think it will let me do any food that actually needs cooking. These don't come any hotter?"
