Plane Sailing said:It used to go like this in our games:
Fred: "I'll knock on the walls, looking for hollow areas"
Joe: "meanwhile, I'll check the edges of the door for trick hinges"
DM: "Fred, there is a hollow sound just behind the bedstead. No obvious way of opening it though. Nothing around the door, Joe."
Joe: "I'll try each of the torch sconces"
DM "The third torch sconce moves, and with a creak the secret door opens"
If I may note - there was a distinct difference between searching for traps, which was handled by a die roll - and searching for secrets, which often was role-played. (And it also depended greatly on the DM and adventure).
Cheers!
