Haha, It took 10 doors or so until I realized that! Until then I was brute forcing all combinations (it are only 27, so no big deal anyway) Makes me wonder, who ever designed the doors - what did they think would be the benefit of this? 27 Combinations? Where the combo is written on the key you need anyways??? Took me about 30min to figure that out. I decided to read the journal from the guy who had the claw. It said, "those who hold the key have the answers in their hands". So basically, the answer was on the key. I know, it's like writing your locker combination on the locker. I mean, why make a puzzle door at all if you're only going to write it on the key? Why not just use a doorknob? Draugr logic. No wonder they're all dead :P
