It's as Savyna pulls around the corner that she hears a shocked exclamation from above, as the drow sees her. He's carrying supplies to repair the trap, and hastily pulls out a rock to drop on her, then pulls out some oil and eyes the edge of the wall that she's holding onto, obviously hefting it consideringly as she's thirty feet from the top.<br/><br/>((11 to hit with the rock, if it hits, make a climb check, DC 10, or fall.))
