four years training

I don't think Caine knew much about quarterstaff fighting. Murphy had been teaching it to me, however, for almost four years. I got the staff up as Caine swung and intercepted the sock. The weighted end wrapped around my staff, and I jerked the weapon out of his hands with a sweeping twist. With the same motion, I brought the other end of the staff around and popped him in the noggin.
Caine flopped to the ground.
I stood there panting and leaning on my staff. Hey, I'd won a brawl. That generally didn't happen when I wasn't using magic. Mouse seemed fine, if occupied holding his thug down.
"Jerk," I muttered to the unconscious Caine, and kicked him lightly in the ribs. "I have no idea what happened to your freaking keg."
