I've recently been playing the RTC version of DM with twice as many monsters. Near the end of the worm level, I started finding monsters that had escaped from their usual places - first some screamers, then a mummy. When I reached the imprisoned mummy, I found the worms had already been released, though a mummy was still standing on the pressure plate.
- How would the screamers escape the regeneration room with the door closed? Could they have been placed in a wall, and moved into the neighboring corridor?
- Could the mummy escape by falling into the pit and teleporting out?
- Do pits usually kill all monsters in RTC?
