Lightning Storm Trap CR 8
Used to protected treasure rooms, this trap sprays electricity from a suit of armor in the corner. Since it is triggered by noises as quiet as two coins clanging together, thieves fill up their bags with coins will set it off. However the trigger is disabled when the fingers of the suit of armor’s right fist are pointed out. Because the suit of armor is metal, failing the Disable Device check by 5 or more sets off the trap.
