A Selection Of Fine Traps: The Horrible Spinning Room
A round room, 100 feet across and 15 feet high, with one big pillar in the center and 6 doors. It is all very fine wood, expertly carved. There are sofas, chairs, tables, and stools all over, seemingly carved right out of the wood of the floor. There are many interesting items on the tables. Many look expensive.
Sadly, 10 seconds after the final person enters the room, a massive stone block falls and blocks access to the outside. Then the room begins to slowly revolve. After every turn by the pCs, it picks up speed. A voice tells them to press one on the now glowing yellow lights on the central column to stop the spinning. This will get harder every turn as the centrifugal force pushes the PCs outward. If they haven’t shit it off by turn 10, it’s probably hopeless and by turn 15 they will all be dead.
