Slamming Pillars (5e Trap)
From D&D Wiki
This trap uses pressure plates to slam those that step on them into the ceiling.
The trap is activated when someone steps on a pressure plate. A successful DC 15 Wisdom (Perception) check discerns an absence of foot traffic over the section of floor that is one of the trap's triggers. A successful DC 15 Intelligence (Investigation) check is necessary to confirm that the trapped section of floor is actually the trigger of a trap.
When triggered, the whole floor begins to spin and the circular stones thrust upward in a column slamming into the ceiling 15 feet up. A creature standing on a pressure plate must make a DC 15 Dexterity saving throw, taking 14 (4d6) bludgeoning damage on a failed save, or half as much damage on a successful one.
The trap resets 1 minute after it is triggered.
