After playing the game thief, which seemed very Lankhmar, I was impressed with the climbing claw item. My guess is that it is rare, worth 3,000 gold or something. With practice, one can scale vertically without leaving a mark. I guess leaning into it and using arms and legs perfect would be how its done. Pitched roofs would be near impossible to get up on for it would seem the thief could not let go of any weight or motion. I used to think climb walls was something like jump up and get a hand hold or scramble for some grab or pole or something. The climbing claw thing seems more interesting. More shadows to hide in way up high I guess. Any climbing claw rules?
