What is chest complexity based on? I have heard several thoughts. But here's what's weird to me. I have only ONCE found a Master level locked chest. EVERY one I have found in the past week has been simple, no matter where I find it. And I only once found, in the very first quest I did, an "Impossible" lock. Do you get better so what was once Master goes down, and I am the god of lockpicking now? Is that why? Or are Simple locks just very common? Anyone know?
