Hello, I am some random notes! A Secret Door can never bypass a printed door or portcullis. If you fail to climb up and fall, and the rules call for d6 damage, take d3, and draw no Room or Trap card, like other cases where you try to move but fail. Besides when tiles let you climb up and down, climb down after evading a Trapdoor; up after falling through one. Rope gives +2 bonus to climbing, and discard it to turn a failed climb down into a success.
