Rincewind stands very still, but his eyes are doing a mad tango, flicking from Xellos and the staff, to the cones and beach balls. All right, he's been in Hell, he's been up with the gods. He's lived in Ankh Morpork all his life, for goodness sake! He should be able to do this...Right, now to convince his feet to move. He takes tiny, tiny steps, picking the blue line at random. His hand hovers near the plate. He's got to keep his head up and still, while staying on the line and not dislodging any of the balls. Easy as falling off the Disc. One step, then two. Mad grab for the plate. Steady! Good! Now one more step...
