*Here is another installment of exTRAPaganza, our Thursday over-the-top trap series. *

The ceiling and floor are made of absolutely smooth metal. The doors go floor to ceiling. The top of the doors are sloped and angled.

The floor is calibrated to detect weight. When 200 lbs. of pressure is applied the ceiling starts to lower. It takes 2 full rounds to lower.

While lowering, the doors are stuck and cannot be opened, as they open into the room. The angle and slope of the doors cause them to shut right as the ceiling pushes on them.

Any creature in the room within 5′ of a door may roll for Initiative. Any target with an Initiative > 20 may escape through the closing doors.

The doors may be destroyed (AC 15, 30 hp) or broken open with a DC 22 Strength check.

Once the ceiling hits the floor, all targets take 100d6 bludgeoning damage, and then the ceiling rises back.
