It's for the best, since I was going to be delaying 'til last anyways. Since it seems like we've been spotted, I propose a revised plan: There's one lighter-armored figure on the airship, so I suggest we just charge the airship, knock the hell out of that guy and pull up the ramp. That seems to be our best shot at dividing them and controlling any means of escape.
Also, sorry DrZ but I finally remember the one last spell I was going to cast: Fox's Cunning.
