Random items not random?

So, I was playing around with a test game and advancing it dozens of turns to get more gems for Wishes.

At one point, I checked my lab for an artifact that got knocked off my Lich and I see......

Six Crowns of Command, four Swords of Sharpness, five Rings of Frost, and four other assorted items.

So that can't be random. The question is: what is the real formula for getting random items?

I really wish the random items were improved some. Would make taking luck more interesting. I always end up with a plethora of unusable level 1 items like swords of sharpness, or those thicket branch things.
