Someone showed how seeds work long time ago by putting thousands of monsters on screen at same time. The odds of them dropping exact same item was quite high. When I find a high rune I make sure to clear as much around as possible. More likely to find two of the same thing close together.

reaaaally? so the odds are just rare to find the item once but back to back is not actually that much rarer youre sayin
the rng is not truly random
its seeded to appear random
