I'm playing through the game as an unarmed character, and I just noticed I have 10-10 magic damage in addition to physical. I got this after equipping earrings with +7 magic damage which I got from beating the killer bunny (as Im level 11, I killed it with a LOT of arrows from the safety of a river).

From reading other reports on unarmed combat it was my understanding you couldn't get magic damage on unarmed like you could with weapons. Now that it seems you can what are the ways to increase this? Is it just getting items or enchants that increase magic damage?
