72. Irregular Room

(20'x30' room, southwest corner chopped 10', 10'x10' alcove north in northeast corner, door west to room 71) In the middle of the 10'x10' square alcove is a chest. It isn't locked; if it is opened, a 5'x5' section of ceiling directly above it will emit a loud grinding noise. It's a falling ceiling block, and it was supposed to fall instantly, but time has corroded the mechanism so that it is delayed one round before falling. The chest appears to be filled with gold coins; actually they are copper pieces which have been plated with a very thin layer of gold (so 54 the coins are worth no more than 1 cp each). There are 472 such coins in the chest (which has a raised bottom so as to appear more full). Characters attempting to spend such coins as gold can expect to be found out quickly; if melted down for the copper value, the party will be paid no more than 2 gp for the whole mess. If the character opening the chest does not leave the alcove instantly, the ceiling block will fall, doing 2d8 points of damage to the character(s) under it. A save vs. Death Ray (adjusted by Dexterity) can be made to jump clear at the last moment. There is a treasure in this room,
