Iron Maiden Trap

Trigger A creature steps onto the trap's pressure plate (indicated on the map) --- Effect The front of the iron maiden slams shut with incredible force and locks itself. The triggering creature takes 4d10+10 piercing damage and 2d6 persistent bleed damage (DC 26 reflex save; if the creature critically succeeds, they avoid the trap completely). The triggering creature is also Immobilized. The victim can end their immobilization only once a creature outside the iron maiden unlocks the device (requiring two successful DC 28 Thievery checks to Disable device) or breaks the iron maiden, after which the trapped creature must succeed at a DC 25 check to Escape the trap's spike-lined interior.
