Welcome to the Coils [reaction] Trigger A creature enters the northernmost alcove; Effect Zyphaniss’s telepathic chuckle echoes in the minds of all creatures in the area. A 9th-rank wall of force appears across the entrance of the northern alcove. Any creature in that alcove can attempt a DC 38 Reflex save to leap out of the alcove before the wall of force traps them inside. The hazard rolls initiative.
Routine (1 action) The ceiling of one of the four alcoves— starting with the southernmost alcove and moving one alcove north each round—slams down with incredible force. A creature bracing the ceiling can prevent it from descending by making a successful DC 44 Athletics check, but the creature must repeat this check each round. The ceiling drops if the creature fails the check or leaves the alcove. Creatures and objects in an alcove when a ceiling drops each take 6d12+41 bludgeoning damage (DC 44 basic Fortitude save). A creature that takes this damage also falls prone. The contents of the alcove are then teleported to the secret hallway north of area H2, leaving the alcove filled with nothing but a block of solid stone.
Reset Once the ceiling of the northernmost alcove descends, all four ceilings return to their original positions, the wall of force sealing the northern alcove disappears, and the hazard resets. Opening the iron door (even from the opposite side) permanently disables the hazard.
