The creature had Sak'bas pinned to the ground, biting and clawing at his as she desperately tried to hold it off - as the largest, she was likely the one it saw as the 'best to hunt'. Its focus on her, though, left it open to his shots, and he took out one of its eyes, with his ray. The rest of the party scrambled back into the fight, Sydon leading the way... and getting snapped at by the huge beast, for his trouble, but the distraction is enough for Nordri to leap onto is back, find a weak spot in its plating, and drive his rapier into it, causing the beast to bellow in agony, before collapsing.
