Codexa, I have not answered that question before and had not personally thought of it. After taking a moment to check the Harry Potter wikia (such a glorious site) I have decided to allow it. There will be a quality for it, and yes, two students can have it.
The two famous wandmakers from the books were Ollivander and Gregorovitch. Grindelwald was the friend of Dumbledore's who stole the elder wand. So both were significant, wand-wise, but I wanted to make sure you had the right name.
I think it is a minor enough spoiler to admit that duels will eventually be allowed and even taught. During these teacher-supervised duels, swords will not be allowed. However, students may decide to practice on their own, and during these sessions, it is anyone's guess what will be allowed.
You can expect me to follow the examples of the books. Classroom scenes exist to provide information an side plots, give different glimpses of other characters and allow for interaction. Most of the story involves events completely unrelated to structured academic enrichment.
EDIT: Metamorphagus added to Qualities.
