Viscid Shells. Many adventurers get a nasty surprise when they try to stab or slash at the shell. Intuitively, the attackers aim for the crevices between the rocks, only to find their weapons hopelessly stuck fast in the shell's binding agent. To further complicate matters, bashing on the shell with blunter weapons doesn't prove particularly effective. Often, weapons of past victims are compelling lures, for few can resist a seemingly unattended sword sticking out of a pile of rocks.
