Wand/Spell of Detect Secrets
Something to make secret doors easier to find
I think given that levels can be much bigger than in ADOM, connecting paths on levels are more complicated, and that we don't have the "You really hurt your foot kicking the wall" message when hunting for secret doors, it might be nice to have a wand (preferably), scroll, or spell that would detect secret doors, either in the line of sight, or on the whole level (like a wand of gold detection that just shows doors). As it is, even for a constantly searching thief, it's often extremely difficult to find secret passages and most of the time you have to just dig randomly around the level in the hopes of something turning up if you think there's a secret room.
