She stiffens, noticeably, as Chess grabs her arm... and for good reason. The half-drow can feel, carefully tied to her upper arm, a long, and very sharp, dagger, apparently rendered invisible, though that doesn't stop her from feeling it.<br/><br/>She then attempts to jerk away, and run from the room.<br/><br/>(30 on her Escape Artist check, to slip free of Chess' grasp, though you'll take a -10 to your check, since you'd only grabbed her arm, and were likely surprised.)
