Alternatively, they may take a more active approach, sensing prey through a dividing rock wall and putting their powerful arms and claws to work to spring an ambush. A cave troll has no fear of tunnel collapse or of natural predators; it can will its already tough skin to become as hard and impenetrable as rock for a short time.'
