The shape takes a few short steps into a new position, and Gur and Banion take their shots. It almost seems as if Gur's attack should hit, but the arrow bounces off the shape. Apparently, it is at least lightly armored. Banion's mindblade is far off the mark, on the other hand. The figure then takes its own shot at Banion, which glances off his armor.
Gur takes two more shots, which both miss. Banion and Beamer move along and take their further shots (does Banion still want to ready a throw, or actually perform it now?). Despite the darkness, Beamer manages to hit the shape, and the grunt it lets out suggests that the hit caused a wound, as well.
Azaroth enters the corridor beneath the left wall. It appears to be entirely empty. Far south, the corridor predictably turns east. In the north, it appears as though the corridor has collapsed.
