Complex Magical Trap 
Source Pathfinder #157: Devil at the Dreaming Palace pg. 49
Complexity Complex
Stealth +10 (trained) or DC 23 (expert) to spot the glyph
Description An invisible magical glyph on the guillotine's blade detects living creatures in the room, which causes the guillotine to fly off its hinges and attack.
Disable DC 20 Thievery (trained) to erase the glyph (which requires a successful unarmed attack roll if the blade is already active) or dispel magic (3rd level; counteract DC 20) to counteract it. The trap has a secret bypass known only to Ralso and Pratchett: as long as the guillotine can see a creature in the room touching thumb and pinky together with an empty hand, it remains dormant.
