All that is left is probability. This game's random number generation is rather shaky. Thus, you MIGHT think that a stone of jordan should be as likely as a manald heal, but you'd be wrong. You might think that Arctic Mitts and Iratha's Cuffs would be equally likely to drop, but you'd be wrong. You might think that the three layouts of the Outer Cloister would be equally likely to encounter, but you'd be wrong. There is a clear ordering of probability there, with the barracks on the lower right showing up far less often. Seems to me that some possibilities in the Arcane show up far more than others, despite its dashing of all my theories. However, I just don't have enough data to offer anything meaningful at this time. I doubt observation alone could puzzle it out, and I'm not the sort who delves into the code.
