Slamming Door
HAZARD 1 +7 (trained)
Pressure-sensitive panels in the floor connect to a stone slab hidden in a hallway's ceiling.
DC 15 Thievery (trained) on the floor panels before the slab falls
AC 16; Fort +10, Ref +2
Hardness 5, HP 20 (BT 10); Immunities critical hits, precision
Slam Shut
Pressure is placed on any floor tile.
The door falls, closing off the hallway. The stone slab deals 3d8 bludgeoning damage to anyone beneath or adjacent to the slab when it drops and pushes them out of its space in a random direction. A creature that succeeds at a DC 17 Reflex save takes no damage and rolls out of the way in a random direction. On a critical success, they can choose the direction.
Lifting the fallen slab requires a successful DC 25 Athletics check.
Hitting the floor panels triggers the trap. The slab uses the same AC and saves as the trap, but it has Hardness 12, HP 48 (BT 24).
Once this trap is triggered, the area of the fallen slab is greater difficult terrain until the trap is reset, which requires 1 hour of labor.
