Slamming Gate

HAZARD 5

Stealth +13 (expert)

Description A pressure-sensitive floor panel causes a spiked door to slam down into place from the ceiling, skewering anyone caught underneath.

Disable 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

Trigger Pressure is placed on the associated floor tile

Effect 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).
