This spell makes a lock or other small mechanism seem to be
trapped to anyone who can detect traps. The character places the
spell upon any small mechanism or device, such as a lock, hinge,
hasp, cork, screw-on cap, or ratchet. Any character able to
detect traps, or who uses any spell or device enabling trap
detection, is 100% certain a real trap exists. Of course, the
effect is illusory and nothing happens if the trap is
"sprung"; its primary purpose is to frighten away
thieves or make them waste precious time.
If another Leomunds trap is active within 50 feet when
the spell is cast, the casting fails.
