... Getting Levrolurment's help for this will be Fun. "How hot can prestidigitation get?"

"Eventually water turns into steam?"

"That should be enough. We'll need to wash her clothes in hot water to kill the mites."

Glorified laundry wizard again. "Prestidigitate isn't enough?"

"It might be, but this is infectious enough I wouldn't want to take the chance."

"Strip," he says to the girl, "we're going to clean your clothes."

... Thanks, Tanidio. "We'll get you something to wear in the mean time." (And also have to wash, but endless washing is just how treating scabies goes.)

She doesn't seem to have any particular self-consciousness about being naked in front of two strange men. (She also clearly hasn't hit puberty.)

When the halfling brings the water he will go back to being a glorified laundry wizard. 

It's important work.

Bun goes to see how easily he can get Levrolurment to part with some sulphur.

"All right, but first you have to tell me whether you would kill someone in Tian Xia if their fortune would be immediately Teleported to you and if it were supernaturally guaranteed that no one would know you had killed them. And tell the truth, please."

"--I would not do that, because that would be immoral."

"Why do you find something being immoral motivating?"

??? "I don't want to do immoral things, because they are bad and harmful to other people." He's just. Not going to try and explain karma here unless he has to.

"Why do you care about things being harmful to other people? You aren't them."

Tanidio honestly thinks this is a good point.

"--but I could be them?" No, that's a bad explanation. "Or-- they're not actually different from me in a way that matters? If something is harmful to them, that matters in the same way as if it was harmful to me?"

"I guess that's as good as I'm going to get, here's the sulfur."

...Tanidio is not really sure he cares whether things are harmful to him either, and he guesses he does want everyone to be useful tools of Asmodeus's will.

"I still apologise for being a doctor and not a philosopher."

How does Imelda feel about getting covered in lard with sulfur in it, and having her hair gone over with a fine toothed comb. ... He's going to do it anyway, but he would like permission.

"Why does it work?"

"The sulfur is poisonous to the mites, and so if we treat you for a couple of days, it should kill all of them."

Suspicious: "is it poisonous to me."

"If you ate it, yes, but the mites are eating it and you aren't."

She nods, satisfied, and lets him work.
