"That will be really nice and really useful, I bet, because I have to check now whether I'm doing real witchcraft or the witchcraft my magic learned that might not be the same at all."
"Hi, Raha! We need to be extra careful today because I think my magic learned how to do witchcraft and I don't know what happens if my magic and Elcenia's magic are doing it at the same time," she explains. "I think I'm mostly going to try to only do the Elcenian kind, but I also want to try my magic's kind some to see how they're different."
"Yeah! Witchcraft didn't work at all on Earth before, but I got it to work there this morning, except that doing it felt like doing my own magic and not like doing real witchcraft."
"Ooh," says Matilda, lighting up. "Yeah! More than one, to really make sure, I think."
Matilda works very conscientiously on her vitamin potion. She is fascinated by the new look at wizardry she gets through the analysis spell, and as far as she can tell she isn't doing any extra magic on top of the witchcraft.
Matilda double-checks that all of the ingredients are things she has heard of or expects to be available on Earth. (Her vitamin potion is coming along beautifully. She is an excellent student.)
Over the next two days she completes her homework, and then she comes back with all of the potions finished. They all came together fine, but of course she needs Raha to verify that because she doesn't know what any of them are supposed to do.
When she floats some objects by way of demonstration, her magic acts upon the objects while she's floating them, and then slowly fades from the objects after she sets them down.
When she whips up a batch of elixir base being very careful to do only witchcraft, her magic doesn't interact with it particularly.
When she whips up a batch of elixir base using witchcraft as well as her magic, her magic acts on it while she's working and sticks to it afterward, and in addition, the liquid has a faint shimmery glow that elixir base is not normally known to have.
"Well, that's interesting," says Matilda, peering at it.
