Secret doors, leading to concealed passages and unseen rooms, are well-hidden from the naked eye. They are constructed to blend into the surrounding walls and most of the time characters will need to find a disguised mechanism to open them, such as a notch or switch.
Elves are able to spot these doors a roll of 1-2 on d6, just by walking past them. If the party takes 1 turn to search, an elf will succeed on a roll of 1-4, and everyone else on 1-2.
