Slamming Gate
HAZARD 5 +13 (expert)
A pressure-sensitive floor panel causes a spiked door to slam down into place from the ceiling, skewering anyone caught underneath.
DC 26 Thievery (trained) to jam either the floor panel or the associated winch
AC 22; Fort +15, Ref +5
Hardness 12, HP 50 (BT 25); Immunities critical hits, precision
Slam Closed
Pressure is placed on the associated floor tile
The door falls, closing off the hallway. The door deals 3d8+3 bludgeoning damage and 3d8+3 piercing damage to anyone beneath or adjacent to the door when it falls, and it pushes them out of its space (away from the door, or in a random direction if the creature is directly beneath the door) as it falls. A creature that succeeds at a DC 22 Reflex save takes no damage and moves out of the way in a random direction. On a critical success, they choose the direction.
Lifting the closed door 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 8 and 60 HP (BT 30).
