18. Chasm
-
At this point the floor of the tunnel disappears
into a 20-foot-wide chasm that blocks
further progress. The sides of the chasm are
sheer, and the pit itself is 200 feet deep. At
the bottom there are no exits. The walls
around the chasm are dry rock, and a thief <Climb, DSG/WSG>
can climb them at his or her normal percentage. <Crossing a Chasm on a Rope, DSG/WSG>
Check every 10 feet, i.e., twice if the
thief is climbing to the other side of the pit.
