Stealth DC 22 (expert)

Disable

• Thievery DC 22 (trained)
• Crafting DC 25 (trained) — to use a loose iron bar to shore up the ceiling.

Trigger A Medium or larger creature moves through the cell at a faster pace than simply Stepping, or more than one Medium or larger creature enter the cell at the same time

Effect The ceiling and walls of the cell collapse, creating a thunderous roar. All creatures in the cell must attempt a DC 25 Reflex save; the cell then becomes greater difficult terrain that can be passed through safely.
