Wow…. You guys have gotta be kidding me "THE KEY IS IN THE PALM OF YOUR HANDS!" It's literally enscribed on the key! ALSO: there are only 27 possible combinations! 3X3X3 = 27. The fourth one: 3x3x3 = 27 x3 = 71 combinations. Bring back the old Oblivion lockpicking. That shit was actually somewhat realistic to real life lock picking, and even so, the game gave you crutches that in real life, you wouldn't have. Balanced realism and difficulty. And killing dragons is the same: Evade/Block their breath, then attack them like you normally would.
