31 BROAD HALL. This stretch of broad corridor is inhabited by an ankheg.
Ankheg (AC Overall 2, Underside 4; MV 12” (6”); HD 7; hp 38; #AT 1 bite; D 3-18 (+ 1-4); SA Squirt acid for 8-32; XP 654)
The hall is decorated in the same fashion as Area 1 of this level with horrible faces decorating the walls and orange-green light permeating the area. The ceiling height remains fourteen feet.
Attempting to excavate the collapsed portions at the extreme east and west will likely result in further movement of stones and rubble, causing 2d8 damage unless a saving throw vs petrification is made. Expert miners with proper tools and methods will eliminate that possibility.
