62 ROOM OF THE PIT. A covered pit trap is near the entrance to the room. If it is not discovered and avoided there is a 4 in 6 chance it will open. Anyone who steps on it must save vs paralyzation or fall in. It is ten feet deep and full of broken glass (for a total of 1d6+1d4 damage). Near the south wall is a juvenile killer mimic disguised as a treasure chest.
Killer Mimic (AC 7; MV 3”; HD 4; hp 18; #AT 1 pseudopod: D 2-7; SA Glue, surprise; SD Camouflage; XP 157)
There actually was a treasure chest here before, which the mimic ate. The treasure is still in its guts: 328 silver spanners and an amethyst worth 200 gold crescents.
