Teaching: Hand-to-hand. In case anyone wants to learn to do more than just defend themselves, he can actually teach them how to fight with hand-to-hand combat.

Regularly taking: None, since he's pretty comfortable with his abilities as of now.

Sometimes taking: Caeldonian Weaponry and Swording, he'd probably peek in on occasion
