Trent Tokens
Scroll Detect Secret Doors - 2004 (Wooden)
Reveals all secret doors in the room to the caster
In years past, it allowed the character to search a room for subtle tell-tale signs of secret doors. The effect was somewhat short-lived. The player was given a UV light and had 30 seconds to search for secret doors or compartments, which glowed red under the special light.
