[QUOTE="Mannahnin, post: 9815556, member: 7026594"] Ah, no. You couldn't automatically detect traps or secret doors in TSR versions of D&D. You've misremembered the rules and are conflating four different ones in this bit. Dwarves in OD&D, AD&D, B/X and BECMI have an enhanced ability to find "room traps" (as B/X labels them) while actively searching. 2/6 instead of the normal 1/6 (AD&D makes it a bit more complicated and limits it to stonework features, though of several kinds), see 1978 PH 15-16, 1989 (PH p21), but that's the short version.) No passive detection ability. "Treasure traps" / small mechanical device traps you need a Thief to actively search for. No passive detection. Elves in AD&D, B/X and BECMI have an enhanced ability to find Secret Doors while actively searching for them - 2/6 instead of the normal 1/6. OD&D stands out as more generous, letting elves find them 4/6 and others 2/6, and offering an optional rule for elves to have 2/6 passive detection (Book III: TU&WA p9). AD&D adds a second, easier-to find category of hidden doors, called "Concealed Doors" (definitions quoted below). And it gives elves a [B]1[/B]/6 chance to automatically notice Concealed Doors by passing within 10', not Secret Doors. It also gives a 50% (3/6) chance to find a Concealed Door while actively searching. [/QUOTE]
