One fairly successful (but sadly deceased

) character of mine managed to find the dwarven pick of erebor (in the sandworm lair, I think). I had some other nice properties, but climbing came in really handy. It made taking down some pretty tough monsters much easier. GWoP just summoned some annoying great wyrm of foo? No problem, just stone prison him for later, retreat into the mountains, and switch places with the nasty! Unfortunately, I've only found a source of climbing one other time (a climbing set from the black market). What's a good place to find some source of climbing? Looking at the edit files the pick's not too rare (lower than Holcolleth, Colluin, and Collanon, which I find all the time in the lair), and a depth of 50 isn't much of a problem when you've got a bunch of greater vaults at lvl 30 of the lair, but I'm doubtful as to whether I'd be able to find a specific artifact. What would be good place to hunt for a source of climbing with a mid-level (high 20s to low 30s clvl) sorcerer?
