10 PIT TRAP. This is a teeter-totter style covered pit. The surface has been painted to resemble the surrounding stone floor, but is made of plaster over wood. The first row of the marching order might succumb to this trap. A saving throw at -4 versus petrification allows one to pull back before falling in. It is ten feet deep and lined with broken glass from wine bottles from Room 11 (1d6+3 damage).
