Rigged Cargo Collapse
Hazard 1[MECHANICAL] [TRAP]
A concealed tripline releases suspended chain and destabilizes several heavy crates, sending them crashing into the storehouse aisle.
Stealth DC 17 (trained) to notice the thin tripline, unusually tensioned retaining rope, or fresh alterations to the shelving
Description A nearly invisible cord stretches across the aisle approximately ankle-high. Disturbing it pulls a retaining pin from an overhead storage frame, releasing heavy chain and causing nearby crates to collapse into the passage.
Disable Thievery DC 15 (trained) to disconnect the tripline without disturbing the release; Crafting DC 16 to brace the shelving and secure the suspended load.
A character who has detected the trap can also avoid the trigger entirely by stepping over the line and warning others, though the trap remains armed.
