Deadly Workshop
Level 5
A workshop strung with a lethal lattice of chains, each link studded with hidden blades and wired through a complex system of pulleys that sets the whole room swinging at once. Spotting the blades and their pulleys takes Stealth +16 (expert).
Disable it with Thievery DC 20 (expert) on the control panel on the raised platform to deactivate the trap. The chains have AC 21, Fort +12, Ref +14, Hardness 14, and 50 HP (BT 25) to destroy the chains and disable the trap; they are immune to critical hits, object immunities, and precision damage.
