Dryus are just male Dryads, and that's all that's different about them.

And, of the Buggirl types, Arachne are Queen.

Onto the skills, even if there are gaps, what is presented is a really good approximation of her skills, as she's very much self-taught from the books that she gathered and trial and error; hence, her goal of mastering medicine.

There maybe come time in the story for why she was self-taught.

I'm looking forward to the magic, and I'm glad you like her, overall. Very spur of the moment character for me.
