Piercers inhabit caves, caverns, and similar subterranean places. With their
stoney outer casing these monsters are indistinguishable from stalactites
found on cave roofs. They are attracted by noise && heat, and when a
living creature passes beneath their position above they will drop upon it
in order to kill and devour it. Larger varieties will be found with smaller
ones.

The size of a piercer is equal to its HD, and there is an equal
probability of a piercer being 1,2,3, or 4 dice in size. The largest piercer is
about 6' long, 1' base diameter, and weighs 500 pounds.

ADQ: What kind of attack do piercers
have after they land? What is the damage
for the succeeding rounds after a
successful 1st attack?
ADA: None. Their sole attack mode is
dropping on the intended victim. There is
no further damage after the 1st attack.
    Proper staging and the creation of the
right atmosphere is the key to running
piercer encounters. Piercers should be
used in quantity for encounters. The
classic piercer attack is to have masses of
the creatures dropping on the party as it
runs through an AREA.
(Polyhedron #16)

ADQ: What will a piercer do after the
1st attack?
ADA: Since it can inflict no further damage,
a piercer will ignore the party and
climb to the neartest wall if its victim is still
alive and circumstances. 

Q. What kind of attack do piercers have 
after they land, and what is the 
damage for succeeding rounds 
after the 1st successful attack? 
A. Their sole mode of attack is dropping 
on a victim -- and if they miss, they 
don't eat.  After it has dropped a 
piercer will not cause any further 
damage.
