Chemist. From the sound of things, I might be the only one... One of my friends was in the first group brought here and she said she's never met another Chemist. [Actually, she has, it's just that Qrow apparently rarely did anything with his path.] Though it could just be that she missed them. In any event, Chemists are essentially Apothecaries, but they also mix poisons as well as medicines. Presumably since combat is a necessity here.

[Since he is Japanese, not British, he doesn't realize that...technically the two words mean the same thing. "Chemist" brings a very different picture to his modern-world mind when he hears the term.]
