Lots! Well, it's a mix of stuff. I mean, we're not just studying magic, I've been studying science and alchemy and learned a lot about chemical reactions and stuff, too, but...with magic stuff I learned how to make some good luck charms and stuff like that!

[Luca being Luca has focused a lot on the science side of things, though he did want to learn some of the magic stuff because it seems pretty useful in the Trench.]
