Threat Assessment: 2. A bunch of creatures known for looking like stalactites. Then they drop down on unsuspecting passer bys below. Other than that they aren't the most dangerous thing one can find in a cave of a fantasy world.
Limitations: Pretty much of a one shot attack. Only really dangerous in numbers.
Personal Note: Always one of the great WTH monsters of D&D. Everyone falls for a piercer attack once, then for awhile is incredibly paranoid about ceillings till they reach a level where the Piercers just bounce off their heads like rain.
