Now, tin-foil-hat-ACTIVATE, but if one were to hypothetically look at the .dats, one might see that there's no noticeable difference between top and bottom floor Ghrahs / Aura Statues. Similarly, there's no real reason why monster drop rates couldn't vary between monsters on the same floor. Who would have predicted that Raxa only drops off Aura statues near Ulli's spawn point? Maybe (in addition) it only drops off the third, fifth, and seventh statues at Ulli's spawn point. We could be discovering a whole new sampling problem.
